Turn on the ignition start stop button

The idea of using a button to start the engine is not new - it has been used in sports cars for a long time. In competitions, the speed factor of the driver's actions plays a decisive role. For example, doctors, studying the reaction of the well-known racing driver Schumacher, discovered that he owed much of his victories to the ability of his brain to quickly process information coming from the eyes. That is, while his rivals are still “digesting” the received data about the road situation, he is already making a decision appropriate to the situation.

If there is a start-stop button, there is no need to waste precious fractions of seconds turning the key - just “poke” the button.

The mechanisms of sports cars are also designed in such a way that the driver spends a minimum of time on movements associated with steering - that’s why the gear shift lever in such a car has a short stroke. The start button in a sports car allows you to instantly start a stalled engine - there is no need to waste precious fractions of seconds turning the key - just “poke” the button. Installing a start-stop button instead of an ignition switch in a personal car is justified mainly by the convenience of the starting process. There is no need to insert the key into the lock, which is sometimes inconvenient in the dark, and the ignition switch itself often tends to jam.

It is especially convenient to start the engine if you are in a hurry - unnecessary actions begin to irritate, everything falls out of your hands, which will inevitably lead to, let's say, a deterioration in the quality of driving. You can often observe how a novice driver, after an unsuccessful attempt to move off, begins to get nervous when starting the engine - his hand has not yet developed the skills of “blind” driving a car. As a result, it may happen that no one will leave the intersection when the traffic light allows the signal, which, as they say, is fraught with consequences - at least, the mood will deteriorate.

How does the start stop button work?

First of all, “a little history.” Car enthusiasts have mastered installing a button to start the engine themselves quite a long time ago. On a car with a relatively simple electrical circuit, this is not a problem. For example, let's take the VAZ 2108-09.

Installing a start-stop button with your own hands on a car with a relatively simple electrical circuit is not a problem.

On the body panel separating the engine compartment and the interior (popularly called the “chest”), next to the switch, there is a starter activation relay. Many car enthusiasts have encountered a situation where a burnt-out relay coil could be replaced with a finger - just press the contacts, removing the relay cover, with the ignition on. In the same way, you can “ignore” the operation of the ignition switch when turning the key to start. It is enough to “break” the wire coming from the lock to the relay and connect a button with normally open contacts into the break. But such a button can only carry out a start - it will not be possible to turn off the engine with its help. In addition, you still have to turn on the ignition with the key.

How to make such a launch possible

As an example, several options for implementing such an idea are considered below. It is worth considering that when undertaking such a modernization, you need to understand and understand what and how to do, because you carry out all manipulations at your own peril and risk. If during the work you have doubts about the correctness of the actions, you should seek advice from a specialist (auto electrician).

Scheme of starting an engine from a button using a key

There are a significant number of different options for implementing this approach. For example, the diagram below.

And below is a diagram of connecting the relay to the ignition switch

Everything works extremely simply. The key is inserted into the lock and turned. Then the button is pressed and held until the motor starts. To turn off the entire system, simply turn the key to its original position. With this option, all functions of the ignition switch and immobilizer are retained.

Installing an engine start button without an ignition key

This is a more complex option that allows you to start the engine using a button; this approach uses, for example, RZPTF (rear fog lamp relay). Its activation is shown in the diagram shown in the figure:

An additional advantage will be connecting power to the alarm system. In this case, the operating algorithm will be as follows:

the car is removed from the alarm system, power is supplied to pin 1 of the RZPTF, and the backlight turns on;
the button is pressed and held - the ignition and starter relays are turned on, the starter begins to spin;
the button is held until the engine starts, then it is released, the starter relay is turned off, the engine continues to run;
pressing again stops the engine;
After setting the car to the alarm system, the backlight goes out.

This is one of the possible ways to implement such a launch system. During such a launch, other elements can be used. For example, the engine will start when you press the clutch or brake, everything will be determined by the specified starting algorithm.

The idea of starting the engine using a button instead of a key is possible on any car. In this case, a completely arbitrary algorithm of action can be used. The decision on how to start the engine - with a button or with the ignition key - is a matter of personal choice and the skill of the person who will undertake the modification of the ignition system. » alt=»»>

How to start a car with a start stop button

Start-stop button on the steering column of a car

Modern start-stop buttons have a more complex connection diagram. In addition to the fact that the button installed on the conveyor does not serve not only to start, but also to stop the engine, car creators connect it in such a way as to avoid “unauthorized” start of movement. That is, if the car is “standing at speed” with the gear engaged, so that the car does not “jump off” suddenly for an inattentive driver who mechanically pressed “start”. If the car has an automatic transmission, then to start the engine you need to press the brake pedal - the start-stop button is connected to the “frog” - the brake light switch.

With the start-stop button, the engine cannot be started until the clutch or brake pedal is depressed.

On a car with a manual transmission, starting is impossible if the clutch pedal is not depressed. The designers of some cars even provided a hint for the driver who got behind the wheel of such a car for the first time. So, for example, on the dashboard of a Ford Kuga, a bright inscription lights up, indicating the need to squeeze the clutch to start the engine, and in Russian - if the car was purchased from us. The ignition is also turned on with this button - the first time you press it. Pressing it again turns on the starter. Moreover, depending on the features of the circuit, the starter turns on either for a short time interval, regardless of whether you hold the button pressed or not, or the starter works until you remove your finger from it.

How does the button affect anti-theft protection?

In most cases, the presence of the device does not affect the safety of the car in any way. Because the vast majority of modern schemes somehow provide for the use of a key in the car key fob. That is, if an attacker opens the door without the help of the “original” key, the “start/stop” button simply will not start the engine.

Problems can arise when the key fob is excluded from the scheme. This usually happens when the installation of the mechanism is carried out by amateurs. The solution is simple: entrust the installation of the button to professionals.

So what does the start/stop button do? Firstly, comfort, and secondly, saving time. The last point is especially relevant in the modern world, where people are constantly in a hurry to get somewhere. To install a button according to the simplest scheme, no serious knowledge of electrical engineering is required. All a beginner needs is to carefully study the diagram included with each kit and not confuse the colors of the wires.

How to install a start-stop button on a car with your own hands

As an example, you can consider the connection diagram of the start-stop button with an immobilizer on a VAZ 2114. You can buy everything you need at once in a kit. The price for such a start-stop button is approximately 4,000 rubles, but by placing an order online and waiting a couple of months, you can save more than twice. The following are sold complete with the button itself:

2 immobilizer key fobs;
immobilizer reader;
Control block;
wires and connectors.

Due to the fact that on the VAZ 2114 there is no limit switch on the clutch pedal, insurance against accidental starting is carried out by connecting the central unit to the “frog” of the brake light. Not the best option, but “inserting” the parking brake limit switch into the circuit will make using the button completely inconvenient. In general, installing a ready-made button is not a very difficult task if the electrical equipment of the car is not replete with frills.

How to install a mechanism in a car

Before you begin installing the start/stop button, it is necessary to carry out certain preparatory work, which will depend on the car model. The ignition switch is removed from the car. And if the design of the car does not allow this, then a small hole is made on the dashboard, next to the lock. To cut through it, any available tool will do: a knife or an ordinary household soldering iron. This hole will give access to the wiring (you can make a plug for it later).

Next, we consider the simplest and most accessible option for installing a button, which will work like this: the first press of the key in combination with the pressed brake pedal will start the engine, the second press will turn it off.

Consumables and tools

To install the device you will need:

start/stop button;
three relays with four contacts;
one relay with five contacts;
one relay for fog lights;
set of insulated wires with terminals.

Tools and consumables needed to install a start/stop button in a car

The simplest do-it-yourself start/stop button connection diagram

Device installation procedure:

the relay is connected with its positive contact to the positive terminal of the battery (this is the brown wire);
the enabling positive signal of the relay is also output to the positive terminal of the battery;
the general minus is output to ground;
the working contacts from the load relay are set to 12 volts (this is the blue wire);
the control negative signal is output to the “start/stop” button;
the enabling positive signal is not output anywhere.

The simplest connection diagram for the start/stop button allows you to install it in about half an hour

The operation of the device comes down to creating 3 connection points in the car: one should be in the ignition block, the second should be on the brake pedal limit switch, and the third should be on the control wire.

How to properly connect a start/stop device to a car

In other schemes, the above principle remains the same: there is a button with multi-colored wires that are difficult to confuse. If a problem may arise, it will be with the yellow wires, since on some models of buttons there are three of them. Here's what you need to remember: the thin yellow wire on the harness controls the brakes. The two remaining wires go to the ignition.

Keyless start button

It is quite obvious that the starter button in a car increases the ease of use of the vehicle. The standard versions require a mandatory combination of such a Push-Start button with the possibility of Key-Less-Go keyless entry. This combination allows the owner to free himself from the need to use the usual ignition key, replacing it with the so-called electronic key.

Without going into details, an electronic key is a tag by which the owner is identified by anti-theft and other car systems after approaching the vehicle at a certain distance. As for the engine start button, it will only work if the electronic key is in the car.

In practice it looks like this:

the owner of the electronic key approaches the car;
at a certain distance, car systems identify the owner by exchanging signals with an electronic key tag;
then the owner presses a button on the electronic key or simply approaches the car closely;
after this the door locks are unlocked;
the driver sits in the seat and presses the engine start button;

It turns out that the electronic key is used by the owner only to forcefully open and close the car doors. The keyless entry and start system performs all other actions automatically. Now let's talk about installing the Start-Stop Engine button yourself.

How the Start/Stop button works

Before starting all the work, it is important to understand the fundamental features of the device and understand the intricacies of its operation.

Without going into details, the procedure for activating this system itself consists of sequentially performing the following steps:

The last action involves briefly starting the car starter. In order to turn off the car, you should press the same brake pedal all the way and press the magic button.

Execution of the presented algorithm will lead to the desired result only if a number of certain conditions related to the installation of working units and elements are met.

Such a superficial analysis of the system’s operation, however, does not give the car enthusiast a clear idea of its functional features. For a more thorough acquaintance with the operating features of the device, it would be advisable to study the circuit diagram of its connection, which is attached below.

Pros and cons of the device in the car

According to established tradition, let’s try to find out what positive and negative aspects are hidden in installing a “start-stop” button.

Let's start, perhaps, with the positives. If you believe numerous reviews, there are much more of them than there are minuses.

So, the presence of the presented system allows:

If we talk about the negative phenomena associated with the installation of such a device, it is worth noting that they are all rather indirect in nature.

For example, in this case the driver has to get used to an unusual algorithm of actions for a long time. Some difficulties may also arise if the car has an autostart system.

In this case, in order to eliminate the possibility of malfunctions in the operation of the presented device, it becomes necessary to carry out work to reinstall the working module of the key fob. This will require the intervention of specialists and, as a result, unnecessary expenses.

Popular ways to install the starter button

Let's start with the fact that many car owners are attracted by the very possibility of starting and stopping the engine with a button, that is, not using the ignition key in the lock. In parallel with this, additional implementation of a keyless entry system is not expected. It is worth noting that in the case of such an installation scheme, comfort increases, but safety suffers. The fact is that after attackers enter the car, the engine start button is not blocked by anything, since there are no systems that identify the owner.

One of the simplest installation options is the starter button, which involves the parallel use of the ignition switch. With this installation scheme, the ignition is turned on using the key in the lock, and the engine itself is then started from the button. Note that this method has more disadvantages than advantages, since the presence of a “start-stop” button still does not provide the required degree of ease of use.
Another type of installation for starting an engine with a button is the ability to start the internal combustion engine with the gas pedal pressed for models with automatic transmission and the clutch pedal for vehicles with manual transmission. This scheme involves turning on the ignition from the Start-Stop button, while the engine is started directly after pressing the gas or clutch pedal.
It is also worth mentioning the method of starting the engine from the starter button, subject to parallel pressing of the brake pedal. The convenience of this solution is questioned by many, especially if the car suddenly stalls in traffic. Let us add that linking the start-stop button with the gas, brake or clutch pedals in various schemes will require installing a separate sensor on the pedal involved.
The installation of an engine start button with a “delay” deserves special attention. This method of non-standard installation has the least detrimental effect on the starter. The downside is the complexity of installation, which requires turning to professionals and making a number of changes to various car systems.

It turns out that the available installation methods can be divided into the following:

the engine start button only activates the ignition; the start itself occurs after pressing the brake, gas or clutch pedal;
the start-stop button allows you to both turn on the ignition and start the engine;
full installation of an engine start system from a button in combination with the installation of a keyless entry system into the car;

Start Stop system: pros and cons

The “Start Stop” buttons are being improved, but they still have shortcomings that are difficult to eliminate. Therefore, some car enthusiasts consider buttons to be a useless addition, believing that their disadvantages completely cancel out their advantages. First, about the benefits.

Whatever you say, start-stop really helps reduce fuel consumption. Savings can be 10%. This is a real “must-have” for those who constantly drive within the city with its traffic jams and traffic lights.

We must not forget about the environmental component. When the engine is running, a lot of harmful substances are generated and released into the atmosphere - using Start-Stop reduces the amount of emissions.

While sitting in a traffic jam, the engine will not work. Therefore, there will be no noise from it. The load on engine parts and the crankshaft is reduced.

And now about the cons. The main one is an increase in load on the battery and starter, which can lead to their breakdown. To start a car, you first need to press the brake, and some car enthusiasts forget to do this.

If you need to install an alarm on a car with a button, be prepared for the installation to be expensive. If there is a button, you will have to install a reinforced starter, but it is not cheap. Real fuel savings will only be achieved when driving from one traffic light to another - "Start Stop" loses its effectiveness when you have to move jerkily in large traffic jams. In this case, the starter operates frequently, which leads to a decrease in battery charge. It takes time to replenish, and there is never enough of it. Because of this, the system automatically shuts down.

The developers are constantly improving Stop & Start - we hope that in the near future its disadvantages will be minimized. The number of car models with such a system is multiplying in arithmetic progression.

What is the starter button for?
1. Starting the engine with a button, or like a starter button, makes life easier for car owners.
2. Starter button instead of ignition key: popular installation methods.
3. Do-it-yourself starter button: simple about the complex.

Self-installation of the engine start button

To better understand the issue, it is necessary to briefly consider the standard process of starting the engine on cars that are equipped from the factory with a simple ignition switch. In such cars, the power wires from the starter are connected to the contact group of the ignition switch. After turning the key in the lock, the contacts close. This solution is found on older car models. The fact is that a large current passes through the contacts, which leads to rapid burnout.

For this reason, more modern versions received a separate relay. The task of such a relay is to take on the entire load and close the contacts after turning the key in the ignition switch. The ability of the relay to cope with high loads, as well as the ease of replacing this element in the event of its failure, allows us to speak about the reliability of the system. As a result, the service life of the contact group has increased significantly.

To connect the engine start button, it is necessary to determine exactly which contacts are responsible for closing the power to the starter, which allows you to crank the crankshaft with the starter using the button and start the engine, as well as stop the power unit by opening the contacts. These contacts are connected to the engine start button or other elements (depending on the installation diagram), allowing you to completely bypass the key in the ignition switch.

To connect, you need to remove the decorative and protective elements on the steering column to gain access to the wiring. The final goal is the connector located on the back of the ignition switch contact group. The specified connector must be disconnected by snapping off the special latches. On machines without a relay, you will need to find power wires in the contact group that are directly connected to the starter contacts. For an accurate check, you can turn on the ignition in the lock using the key, and then short-circuit the found wires (often these are the two wires with the largest cross-section). The start of the starter after the wires are closed will indicate that the contacts are selected correctly.
The next step is to connect the start-stop button itself. First, you need to select a location for installing the button on the dashboard or in another suitable place, and then connect the necessary power wires from the ignition switch contact group to it. On cars with a relay, wires are connected to the starter button that supply voltage to the relay. For an accurate determination, you can use a multimeter, which is set to the ohmmeter mode for measuring resistance. First, the tester checks the wires from the starter to the car body, as a result of which the “minus” is determined.

Problems with keyless car starting system

As noted earlier, the use of such a system is associated with a number of problems. Most of them cause inconvenience only in the absence of certain skills in using the presented system.

This may include:

How to unlock the steering wheel

Another important problem that motorists who have equipped their cars with such a system often face is unlocking the steering wheel. Of course, as a last resort, you can resort to a barbaric method and get rid of the blockage using simple manipulations with a mounting tool and other tools.

You can solve this problem as follows:

But it’s still much easier to use the services of professionals. The fact is that it is not always possible to unlock the steering wheel yourself, due to the characteristics of a particular car. Therefore, in this case, it is best to contact specialists.

Tips and tricks

The engine start button works in such a way that the driver presses it and holds it for the required time to start. During this period of time, the starter rotates the crankshaft, resulting in the engine starting. Then the button can be released.

Note that when choosing a “start-stop” engine start button, a number of certain nuances should be taken into account. One of these points is the issue of fixing this button. The optimal option is when, after pressing, the contacts are closed, and when released, they open. If the button has a lock, then after starting the engine, you will need to quickly press it again to open the contacts.

For these reasons, it is worth considering when choosing:

a strong current will be supplied to the button;
the solution will be constantly used;

Taking into account these operating features, it is better to choose an engine start button with a high-quality external coating (for example, chrome plating). Such a product will have abrasion resistance to maintain an acceptable appearance. You also need to understand that cheap offers can burn out after just a few clicks, so this aspect should be given increased attention.

Every motorist wants to improve the comfort of using their vehicle. So, installing a “Start/Stop” button will help save you from such a routine task as turning the key in the ignition switch (IZ) to start/stop the engine again. And you will be able to save a little of your “precious time”. You can either make such a device yourself, or simply buy a ready-made kit and install it on your car. The features of installing such a device, its pros and cons, as well as some nuances that need to be remembered will be discussed in this article.

Audi A6 C.C.O. › Logbook › Start-Stop system and its features

As you remember, readers, my car has a start-stop system - which is a unique and amazing feature of the car, because not every car stalls at traffic lights!

And so I was puzzled by this question and started looking for information and testing. There are certain conditions under which the system does not work, there are certain protections, and there are certain tricks, but more on that later! After googling, I came across both the story and the principle of operation - it’s interesting, I’ll tell you, so, pay attention, everything is in order.

In general, what is this “Start-Stop”:

The Stop-Start system is designed to save fuel, reduce emissions and reduce noise by reducing engine idling time. As car operating practice shows, idle mode accounts for up to 30% of the total engine operating time. This is facilitated by frequent stops at traffic lights, being stuck in traffic jams and possibly waiting in a car for someone at the entrance. In your own words - get stuck in traffic jams for free, because both the climate system and the music work!

History of creation:

As for history, this is also interesting, I’ll just give an excerpt from the article dpgo.ru/article/2012-02-1…printsip-raboty-problemy-

How it works:

The principle of operation is to turn off the engine when the car is stopped and quickly start it when you press the brake pedal.
Structurally, the Stop-Start system includes the following elements: - a device that ensures repeated engine starting; - control system. There are several approaches to implementing the multiple engine start function:
- reinforced starter; — reversible generator (starter-generator); — fuel injection into the cylinders and ignition of the mixture. The simplest and most reliable in terms of design is the Stop&Start system from Bosch. Thanks to this system, the name “stop-start” has become a common name for other systems. The Stop&Start system is installed on Audi cars and reduces fuel consumption and harmful emissions by up to 8%.

The basis of the system is a special starter

, designed for a large number of engine starts and having an extended service life. The starter is equipped with a reinforced low-noise drive mechanism, guaranteeing fast, reliable and silent engine starting.

The control system performs the following functions:

— stopping the engine; - engine starting; — battery charge control. Like all modern electronic control systems, the Stop&Start control system includes: - input sensors; - Control block; - actuators. Input sensors include the engine speed sensor, clutch pedal position sensor (brake pedal position sensor), battery sensor, and other engine management system sensors.

The system does not have its own electronic unit, but uses the power of the engine control unit, where the corresponding software is installed.

The actuators of the system are: — nozzles of the injection system; — ignition coils of the ignition system; — starter.

The Stop&Start system works as follows:

When the car stops at a traffic light or in a traffic jam, the system, based on the signal from the crankshaft speed sensor, stops the engine. Electrical consumers (air conditioning, audio systems, etc.) are powered from a battery. When you release the brake pedal on the car, the system activates the starter and starts the engine. Subsequently, the cycle of stopping and starting the engine continues.

If the battery charge level drops below a preset value, the system turns off based on the signal from the corresponding sensor. The system is turned on after charging the battery. The system can be forcibly disabled using a special button on the instrument panel.

The trick is also the reversible generator, which is an alternating current electrical machine that can act as a generator and starter depending on conditions. The operation of the reversible generator is ensured by a special drive belt and a reversible tensioner, which allows force to be transmitted in two directions. The reversible generator operates silently and has a shorter starting time (0.4 s compared to 0.8 s for a conventional starter). Therefore, starting at a traffic light occurs almost imperceptibly.

Required working conditions

The start-stop system only operates at speeds above 4 km/h, with the driver's door closed and the driver wearing a seat belt, as well as other parameters that may be specified by the manufacturer.
In addition, the system will not turn on when the car is not warmed up (this also includes a discrepancy between the engine speed and idle speed), if the heated windows, mirrors and other elements are turned on, the generator is faulty or the battery charge level is below normal, the stop occurred after turning off the rear travel or the steering wheel is turned to a large angle (for example, for parking maneuvers). This is all yes, and at first I thought that if these conditions were not met, the car could only be turned off manually, but no, there are options:
- movement, door, cold car, as well as the battery charge level and discrepancy in rotation speed for any reason - this is invincible; — after moving backwards, the system does not work, everything is simple: you turn off the parking sensors after stopping and the “A off” button clicks and stalls; — the wheel is turned out, and the system does not work, well, it’s generally not very good to turn off the car with the wheel turned out, because the hydraulic system turns off, and there are opinions that this is not safe for it, the principle is the same: you twist the steering wheel until the wheels are straight and press the brake pedal harder; — I didn’t notice the heated mirrors and windows, but in the heat, when the climate control is turned on, the car stalls only when the temperature in the cabin is comfortable; - in general, if the system does not work, you should click “A off” and you will be happy!

They made, in principle, the correct conclusion: “THE START-STOP SYSTEM SAVES FUEL ONLY WHEN THE CAR MOVES THROUGH A HALF-EMPTY CITY AND STOPS BRIEFLY AT TRAFFIC LIGHTS. IN PROLONGED TRAFFIC TRAFFIC TRAFFICS THIS ELECTRONIC ASSISTANT GIVES ALMOST NO GAIN.”

This is actually true - in traffic jams the savings are not so great when you move a teaspoon per hour, but in general it really helps to save money, otherwise how can you explain that a huge business class sedan eats like a small car!

My conclusion:

the system is good, necessary, useful - this is our future! Saves fuel!

Poll at the end:

who has? Who uses it? Who thinks about this?

I hope I didn’t bore you, thank you for your attention! The “like” and “tell” buttons are relevant!

Standard delivery set

The delivery set of the universal device for equipping a vehicle with an engine start/stop button consists of:

control module;
the “Start/Stop” button itself;
built-in immobilizer scanner;
2 keychains;
installation wires;
instruction manuals (with connection diagram).

This kit is designed for installation on almost all models of both domestic and imported cars. The current price (depending on the manufacturer) is 1500÷4500 rubles.

For information! To deactivate the immobilizer, simply bring the key fob close to the scanner at a distance of 2÷5 cm. After this, a sound signal will sound, informing you that the device is ready for operation. 15÷20 seconds after stopping the engine, the control module automatically switches the device into security mode.

Combined modification option

As practice shows, a combined conversion scheme can be implemented even by a novice motorist who is at least a little familiar with the electrical structure of his vehicle. To do this you will need to acquire the following components:

ZPTF relay;
4-pin relay;
5-pin relay;
engine start and stop button;
diodes and terminals.

Having prepared everything you need, including tools (nippers, pliers, insulating tape), you should connect the contacts according to the diagram with further installation of the diode, which can be installed almost anywhere.

How to install it yourself

The easiest way to retrofit a car with a “Start/Stop” button is to purchase a ready-made set (fortunately, the modern market for automobile accessories is replete with such devices) and install it yourself. For any motorist who has at least some electrical installation skills and knows the pinout of the standard ignition switch block, making such an “upgrade” will not be difficult.

On a note! The connection diagrams for ready-made kits are the same from almost all manufacturers.

dismantle the steering casing;
disconnect the ignition switch connector;

we install the control unit, button and immobilizer scanner in the most convenient places for subsequent use;
connect the wires from the control unit to the ignition switch connector in accordance with the diagram (it is supplied with the device);
lay and connect the wire to the “frog” of the brake pedal.

Important! If you purchase an ignition switch block in advance and connect the wires from the control unit to it in accordance with the diagram, then, if necessary, you can quickly return to the standard engine start/stop system using the key. If you were unable to buy a mating contact group for the 3Z (specifically for your vehicle model), then you can successfully use crimp terminal blocks of a suitable size.

Automatic start of the car from the key fob: instructions, description and recommendations

With the onset of cold weather, many car owners are faced with the problem of warming up the vehicle engine. How nice it is to finish your morning coffee, go downstairs, get into your car and immediately drive away. But - looking reality in the eye - we go out into the cold, get into a cold car, start the engine and wait until it warms up so that we can drive.

Time does not stand still, so all car owners have the opportunity to install an alarm system with an auto engine start system on their vehicle.

Description

An alarm system with auto start is a system that not only provides security, but also warms up the engine. The latter is activated through autostart of the car from the key fob. The price varies between 3,000-70,000 rubles, depending on the availability of various additional settings.

The main components of the system are similar for all manufacturers, but there are undoubtedly differences. Therefore, the choice of alarm system should be approached carefully, weighing all the pros and cons. For example, the Starline car alarm kit includes:

Two remote control key fobs.
Central block.
Paging decoder.
Shock sensor.
Led indicator.
Service button.
Remote controlled relay that blocks the engine.

Installation

Each car alarm is installed in accordance with its instructions. In this matter, of course, it is better to trust the professionals. After all, not only the warming up of your car depends on how it is installed, but also whether it will be stolen.

In the case of self-installation of a car alarm, the algorithm of actions will be basically similar for all system manufacturers. Therefore, let’s look at how to install car autostart using the Starline key fob.

The central unit of the system is located in the vehicle interior. It is most convenient to place it under the dashboard. There, moisture will not get on it, and the length of the connecting wires will be reduced to a minimum. The block is secured with self-tapping screws. This is necessary so that it does not move during vibration. The paging decoder is placed near the block.

The siren finds its location under the hood of the vehicle. Its horn must be lowered down - this way you will avoid collecting water in it. The siren should be kept away from sources of moisture and heat. Be sure to check that the wires are inaccessible from the outside of the hood.

Steering wheel unlock options

When we remove the key from the lock, the steering wheel is locked, that is, fixed with a spring-loaded metal pin. In order to operate the car normally after installing the “Start/Stop” button, it is necessary to remove this function. There are two ways to do this.

The first, and from our point of view, the most preferable method:

order a duplicate ignition key;
insert it into the lock and make a mark at a level of 1÷1.5 mm above the surface level;
take out the key and saw off the “excess” in accordance with the mark;
insert the “piece” into the lock and use pliers to turn it to position 2 (now the steering wheel is unlocked);

We leave a piece of the key in the lock until the need arises to return to the standard ignition circuit.

The second way to get rid of the steering wheel lock is to completely remove the ignition switch. In the resulting hole we either mount the “Start/Stop” button or install a plastic plug of a suitable size. The main disadvantage of this method is that it will no longer be possible to quickly “return” to the standard circuit of turning the car engine on/off using a key.

Installation Guide

Installation of an electronic stop system can be done at home. As reviews show, for car owners with experience in electronics, installation of equipment will not cause problems. To begin with, we suggest that you familiarize yourself with the possible diagrams that can be used for connection. In our example we will use the first scheme.

How to connect correctly?

To independently install the equipment in accordance with our diagram, you will need the button itself, three relays with 4 contacts, one with five contacts and one relay for fog lights. You will also need mounting wires and clamps for connection.

The process of connecting the equipment is as follows:

In total, there are three connection points in the car - directly on the lock block, on the brake pedal, in particular, to its limit switch, another point will be the control wire. This circuit will allow you to turn off the starter mechanism after starting the engine.

How to bypass the standard immobilizer

Many modern car models are equipped with an anti-theft device such as an immobilizer. Manufacturers equip the vehicle with a similar standard device already at the factory. The reading device is usually installed in the ignition switch, and the control mark in the key. If the security guard is not dismantled, then a key will be needed to deactivate the security mode. If you decide to remove the lock, then you need to disassemble it, find the immobilizer reader and move it to a suitable location. However, in order to start the engine with the Start/Stop button, you will still have to have the key with you.

For information! Some manufacturers, in addition to the universal “Star/Stop” kits, produce special devices for temporarily disabling (bypassing) the standard immobilizer.

DIY installation options

There are many product installation schemes, each with its own characteristics.

Option with ignition key. In this case, you will need a key to start. Turning it turns on the ignition, and to start the engine you will need to press a button. There is an option without a key - it is simpler, you just need to press a button.
“Short” and “long” press. In the first option, you need to press the button briefly - the starter will spin until the engine is activated. The second involves holding the button - the starter rotates only while it is pressed.
Various options for turning on the ignition. The first option is to turn on the ignition when you press a button. The second is the ability to activate it only together with the starter.

This is what the installation instructions usually look like

Experienced car enthusiasts combine different options, getting interesting schemes. To install the Start-stop button, you do not need to be an experienced auto mechanic - just ordinary knowledge in the field of car operation is enough. But if you want to implement a complex circuit, with a timer, startup delay and other nuances, you will need serious effort and a large number of additional components.

DIY option

The Internet is replete with diagrams for making your own ignition control units using the Start/Stop button. For those who like to do car tuning with their own hands, below is one of the fairly simple options that is easy to repeat:

To make this device yourself you will need:

4 relays: PTF 21.3777 (300 rubles), 231.3787 (150 rubles), 90.3747-10 (2 pieces for 75 rubles);
4 diodes (for example, 4007 - 4 rubles per piece);
button without fixation (30÷70 rubles);
installation wires of suitable diameter;
crimp terminal blocks (“female” - for switching relays among themselves, “male” - for connecting the manufactured unit to the ignition switch block).

The operating algorithm of the circuit is completely similar to the engine start/stop device of ready-made universal kits. Naturally, the homemade device does not have an additional anti-theft function (immobilizer). Otherwise, the scheme is quite workable and has been tested by many car enthusiasts.

Sequence of operations when installing “start/stop” on the ignition switch

To properly install the device into the system, you must follow the sequence of steps below:

First, the ignition lock cylinder is removed, followed by the lock itself.

The ignition lock cylinder has been removed from its socket.

Harness of cut wires from the ignition switch

The wires on the ignition unit are carefully wrapped with electrical tape

Advantages and disadvantages

Any car tuning has both pros and cons. Among the advantages of controlling the start/stop of the engine using the “Start/Stop” button, one can note only a slight increase in comfort and minimal time savings. And here are the disadvantages (where would we be without them):

You will still have to carry the key with you. Firstly, it may be needed to simply open the car if the battery is dead and the electromagnetic door activators do not work (this is especially true at significant sub-zero temperatures). Secondly, in many modern cars the standard immobilizer mark is located in the key, so you can start the engine only if it is in close proximity to the reader.
The installation of pre-heating devices and alarm systems becomes more complicated (due to changes in the standard electrical circuit of the car).

Important! Such modernization of the car threatens to void the vehicle manufacturer’s warranty.
