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.
Algori
The operating principle of such an auxiliary device is quite simple:
- get into the car;
- depress the brake pedal;
- press the “Start/Stop” button and the engine starts;
- To turn off the engine, press the brake pedal again and press the button - the engine stalls.
For information! If you simply press the button without pressing the brake pedal, the engine will not start, since the +12V voltage is supplied only to additional consumers (for example, an audio complex). This is similar to turning the ignition key to the first position - ACC.

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.

Go to the store A luminous red button with a removable chrome surround is installed in the car's dashboard, next to the gearbox. The kit only comes with a start-stop device, no instructions. Due to its small size, it requires minimal power consumption.
This model has bright backlighting. The built-in high-quality module ensures uninterrupted operation of the button in any climatic conditions and temperature range from -50 to +5 degrees. It is recommended to check the size chart before purchasing.
Advantages:
- presence of backlight;
- work in any weather conditions
Flaws:
- marking.

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.
Work order:
- 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.
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.
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.
Maintenance Recommendation
The current power mode is permanently stored in the memory of the power supply ECU. Therefore, if the power supply ECU is de-energized, for example, if the battery is removed, the power supply ECU will restore the power mode to the previously activated state after the battery is connected.
Therefore, if you remove the battery in any power mode other than "Off". (“OFF”), power will be supplied to the vehicle’s electrical equipment at the same moment as power is supplied to the power supply ECU (when the battery is connected). Therefore, before removing the battery, you should turn the engine start button to the “Off” mode. (“OFF”) and remove the key from the slot.
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.
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.
