What is an immobilizer and how to use it on Lada Granta

The immobilizer of the Lada Grant and any other car is a special anti-theft device that does not allow the engine to start. Motorists use it very rarely, even if the Lada Granta immobilizer is included, while others simply do not know about the existence of such a device. But safety cannot be neglected, and that is why all owners of Lada Granta, without exception, should be sure to familiarize themselves with the design and operating principle of this module.

The moment the driver inserts the ignition key, the Lada Granta immobilizer is identified using a code. If there is a match, there are no obstacles to starting the engine and you can start moving. Otherwise, the car will be locked until the correct code is received. There is one important disadvantage of using this device - if the Lada Granta immobilizer breaks down, then it will be possible to start the car only after repairing or replacing the module. In such a situation, the old code is deleted from the controller and new code is written. So, if the immobilizer is blinking, you should think about it and pay attention to it.

At the car dealership, the Lada Granta immobilizer is activated during the pre-sale preparation procedure under the supervision of the future owner. If the buyer refuses to use this function, then this is entered into the service documents, where it is certified by the seal of the car dealership and the signature of the buyer.

Immobilizer Lada Granta (how to disable or activate)

An immobilizer is an electronic anti-theft system that blocks part of the vehicle control modules when intruders enter the car. Such protection is a mandatory attribute of most modern middle and upper class cars. Despite belonging to the economy class, the Lada Granta immobilizer is also included in the standard factory equipment.

A detailed algorithm for reconfiguring the immobilizer

First of all, you need to close all the interior doors, insert the so-called “red” training key, and turn on the engine ignition. If the light is constantly on, it means training is required. Next, you need to turn off the ignition and wait for the immobilizer to blink. Remove the “red” key and immediately insert the regular key, turn on the ignition as usual. At the same time, you will first hear three consecutive short beeps, and after a short time you will hear a couple more. Then turn off the ignition again and re-enter the first training key: three should sound the same, and then the same two short beeps. Turn off the ignition and do not remove the learning key. After this, a short beep will sound and the indicator will flash quickly and rapidly. Turn the ignition on again and then immediately turn it off, after which 3 beeps will sound and the indicator will go out completely. Now you can remove the first “red” training key and use the regular one to test start the engine. So, the immobilizer on Lada Granta works.

It's no secret that Grant's cars are equipped with an additional protection system - an immobilizer, but almost no one has activated it. This protection system should be activated at the dealership during pre-sales, but many dealerships are simply too lazy to activate it, citing faults, etc. After several months of driving, I discovered that the car has an immobilizer for my Grant, but it is not activated. I wanted to go to the dealer and get it fixed, but somehow got lazy. As a result, I found information on the Internet about activating the Lada Grants immobilizer and shared it with all my readers!

How to determine whether the immobilizer on a Grant is activated?

everything is very simple: insert the key into the ignition and start the car, if the icon in the form of a car on the instrument panel (see Figure under number 6) lights up for 15 seconds and goes out, then the immobilizer is NOT activated!

So, if your immobilizer is not activated, below are the instructions to activate it:

• Get into the car and close all doors. • Insert the contact with the RED key (spare key with red mark) and wait 9-10 seconds. • Remove the key. The car icon should flash 5 times per second. • Quickly turn on (within 5-6 seconds) the BLACK ignition (daily key with black mark. • 3 beeps + 2 beeps will sound. • Turn off the ignition and remove the key. • Quickly (within 5-6 seconds) while the car is flashing, turn on the RED ignition • 3 beeps + 2 squeaks will sound • There will be 1 squeak • Quickly (within 5-6 seconds) turn on the ignition for 2-3 SECONDS! • Turn off the ignition LOCK KEY • 3 beeps will sound + the car icon will go out. Do not remove the key.(With some controllers, the light stops flashing and the buzzer beeps 3 times when the power is turned on. In this case, you still need to turn off the ignition and wait at least 10 seconds) • wait at least 10 seconds. • Remove key. • Check the activation of the immobilizer. Turn on the ignition with any key, if when you turn on the ignition the car does not turn on on the instrument panel, the immobilizer is activated.

An immobilizer is an electronic anti-theft system that blocks certain vehicle control modules when intruders enter the vehicle. Such protection is a mandatory attribute of most modern middle and high-class cars. Despite belonging to the economy class, the Lada Granta immobilizer is also included in the standard factory equipment.

Principle of operation

The main advantage of an immobilizer over an alarm system is its ability to break the chains necessary to start the car and prevent it from moving, while an alarm system can only report theft. Even if a thief turns off the alarm and gets inside the vehicle, he will not be able to start the engine and drive away.

There are models of anti-theft systems that allow you to start the engine and even drive several hundred meters, and only then block the vehicle’s movement.

Practice shows that such systems help not only protect the car, but also catch the criminal.

It is impossible to find out how the immobilizer works by the appearance of the car or keys, so it is almost impossible to bypass the system.

All modifications of Lada Granta are equipped with an immobilizer of the first type, which blocks the ignition when opened with someone else’s key or in the event of a break-in. Anti-theft protection is built into the control module of the electric motor and its components. It includes:

• 2 keys (the first is active, the second is training);
• control module;
• signaling device;
• communication coil in the ignition switch.

The system control unit houses a sensor, and a chip with a code is located on the key. The system reads the code and thereby allows or prohibits turning on the engine. The control light indicator is located on the instrument panel and signals the protection position. The model is also equipped with a door lock, which is controlled from the key fob: activated by a single click and deactivated by a double click.

Anti-theft protection operates in 2 modes:

• The immobilizer option is deactivated. In this case, there is no connection between the protective system and the electronic control unit, and the engine is not blocked when started by a third party.
• The function is active. In this mode, starting the engine is possible only with a valid key. If you try to start the engine in another way, the ECU is blocked.

Where is it located and how to activate it

Lada Granta cars are delivered to showrooms with the immobilizer function deactivated. Salon specialists perform activation at the time of sale, in the presence of the client. Sometimes salon employees forget to do this, or the buyer himself refuses to connect the protection. The vehicle owner needs to know where the immobilizer is located and how to make it active.

The brain of the anti-theft system is located directly in the ignition unit, which allows you to read the owner’s special code from the key. To activate the immobilizer, you need to perform the following sequence of actions:

• close the hood, trunk and all doors in the car;
• insert the training key (with a red mark) into the ignition and turn it until the ignition is activated;
• wait 6 seconds until the light on the instrument panel starts flashing;
• within 6 seconds, remove the training key and insert the working key, start the engine with it.

If everything is done correctly and on time, then this will be followed by 3 signals, and then 2 more. If there is no sound, the operation should be repeated again.

Granta Lada car immobilizer

Even though the Granta Lada occupies the automotive sector of the economy, it is still worth a lot of money and no one will lose it if it is stolen. Moreover, at the very least, an inexperienced vehicle poses an unnecessary hazard that can expose drivers, passengers and pedestrians to serious inconvenience. To prevent possible troubles, various anti-theft devices are installed on cars.

The main elements are an alarm system and an immobilizer. Each of these devices has both advantages and disadvantages. The alarm system provides the motorist with some additional comfort-enhancing features, such as opening only the side door or only the driver's trunk, auto start, which allows the car to start warming up without leaving home. But the alarm only notifies the car owner about break-in; the immobilizer specifically prevents theft.

The electronic anti-theft device is an electrical controller that blocks the car's engine from starting if the ignition was started with an external key. The ignition switch key has a built-in chip that sends an owner identification code to the electrical control unit every time you try to start the engine.

Activation of the electronic anti-theft device

Electronic anti-theft device Granta Lada Installed on all models, starting with standard equipment. Granta was one of the first Russian-made cars equipped with an immobilizer. And the first problem that the owner of the latest grants faces after studying the requirements of the “immobilizer” is the activation of the anti-theft accessory. As a rule, the controller is activated by the car dealership in the presence of the owner.

If the client refuses to activate the immobilizer, a note is entered in the service book. When the owner changes his mind and after some time decides to activate the device, he must do it himself. The main thing is to follow the activation method correctly to avoid possible problems. Granta Lada It is presented to the owner with a set of keys, in the middle of which there are two for the ignition switch, one of them is marked black and the other is reddish.

The dark key is used for daily use, in particular, it must be stored in the immobilizer memory for smooth engine starting. Red key , the so-called learning, designed to enter the source code into the controller's memory. Once activated, it should be kept in a safe place and removed only when necessary. If the key is red, all warranty obligations of the seller are lost.

Standard immobilizer Lada Granta Liftback (Chronicle LADA GRANTA)

Judging by the reaction of the salon staff and the fact that they repeatedly apologized to us, a memory was created.

Activation occurs when the car door is closed; there should be no keys in the ignition. You need to stick the red key and turn on the ignition. Wait 6 seconds. If everything is done correctly, the red immobilizer light should flash on the dashboard. The owner then has 6 seconds to remove the red key, stick a dark light on it and turn on the ignition. “Immobilizer” should sound first three, then two more.

If this doesn't work, you must start over. When everything is ok, the dark key changes color for 6 seconds. The beeps must be repeated: three, then two. It (reddish) turns off the ignition, followed by one beep. Turn the ignition off and on again for 6-2 seconds. Turn off the ignition and the red key remains in the lock. After you hear three beeps and one beep, 10 seconds will be counted and the red key will be removed.

How to disable the Lada Granta immobilizer

If the car has an alarm in addition to basic security, a conflict may arise between the anti-theft systems. In this case, you need to deactivate the immobilizer in the car.

To bypass this function on the Lada Granta, you need to create your own secret code. It will help unlock the engine if the key or other system components malfunction. It is important to remember that in order to carry out the shutdown procedure yourself, the code must be written immediately after activating the protection. To do this you need:

• tightly close all doors in the cabin, including the hood and trunk;
• insert the training key into the ignition, start and stop the engine;
• rapid flashing of the diode indicates the start of the procedure;
• in 6 seconds you need to remove the training key and insert a valid key, activate the ignition;
• a three-time beep will confirm the correctness of the action;
• wait for 2 more signals and turn off the engine;
• within 6 seconds the working key is removed, the training key is placed again and the engine is started;
• wait for 3 and then 2 more signals;
• turn off the engine and wait for 1 more signal (after this the LED should blink even faster);
• the ignition is reactivated with the red key, the Check Engine light should go out within 1 minute;
• then enter a six-digit password by pressing the accelerator pedal as many times as there should be in the code number;
• between the numbers, the pedal is held for at least 5 seconds until the CE light goes out;
• After recording all the numbers, the ignition is turned off.

To enter the code, the engine is started, nothing is pressed until the CE lamp stops lighting. The code is then entered by pressing the accelerator pedal as described above.

In this way, the immobilizer on the Grant is turned off until the next engine start. If more than 5 seconds have passed between turning off the engine and starting again, you will have to repeat the code entry.

Disadvantages of an immobilizer

The main disadvantage of this anti-theft device is considered to be blocking of the main components of the vehicle, or partial inability to control it (turning off turns, headlights, etc.). If you try to activate the controller several times in a row, the Lada Granta does not perceive it and stops working completely. The driver is completely confused and does not know what to do next.

In this case, you just need to disable the immobilizer. There is nothing difficult about this, although there may be problems with the controller. If there is a red key, then there will be no problems with disabling the “immobilizer”, since it contains a certain code. There are programs associated with disabling them, but it is not recommended to carry out such repairs on your own, and it is better to trust a specialist.

In contrast to the disadvantages, there are useful properties of the anti-theft agent, which will help protect the peace and sleep of its owner. If you have lost your Lada Grant password, you should not despair; it is enough to purchase a new one and re-learn your car.

It goes like this. The key is inserted into the ignition. If there is no sound signal on the buzzer and the indicator is flashing quickly, it is important to turn off the ignition in a timely manner and perform the training again. If, after repeated repetitions, it is still not possible to carry out detailed and complete training, then the problem is a malfunction or the training key is simply incompatible with the ECU.

Reasons why the standard immobilizer is not activated

• Just lazy.
• Some people demand money for it and don’t want to do it for free.
• Other dealers do not want to activate it, because then, when installing an alarm system with auto start, they will have to perform the “immobilizer bypass” procedure, which brings additional difficulties.
• Some argue that this operation may cause problems with starting the car. A strong argument here is that dealers claim that after activating the immobilizer, the Lada Granta can stall at any time. Then we can suggest not to lock the doors yet, they may not open at any time.

Please note that in the list of pre-sale work there is an item on the basis of which the car's immobilizer must be activated, regardless of what engine (more about engines here) and what equipment.

How to replace batteries in the remote control.

The remote control contains elements of the CR2032 type; to remove them, you must press any button to open the contents of the compartment. It is important that at this time the special indicator on the remote control lights up, but if it does not light up or turns on and off, then this indicates a problem with the batteries. Now we arm ourselves with a Phillips screwdriver with a small blade, which will help connect the housings on the remote control. Next, we pick up the remote control for the Lada Grant and begin to carefully separate the body into parts to see its filling.

After this, you should remove the damaged battery and install a new one, paying attention to the polarity so that the immobilizer can work correctly. After this, it is necessary to remove parts of the remote control housing until the latches snap into place and are completely closed.

How to find out if the immobilizer is activated?

This should not be confused with the “check engine” icon, which also lights up when you turn the ignition key. This icon does not go out until you start the engine. Learn more about why your check engine light may come on here.

If this icon is lit, it means the immobilizer is not activated.

If, when starting the car, the “car with key” icon lights up and goes out after a while, then the immobilizer is disabled! This is a direct threat to the safety of your car.

Instructions for activating the immobilizer

• Close all doors by pressing the button (door lock button).
• Turn on the ignition with the RED key and wait 9-10 seconds.
• Pull out the key . The “car with key” icon should blink 5 times per second.
• Quickly (within 5-6 seconds) turn on the ignition BLACK. There will be 3 beeps + 2 beeps.
• Turn off the ignition and remove the key.
• Quickly (within 5-6 seconds) while the “car with key” is blinking, turn on the RED ignition. There will be 3 beeps + 2 beeps.
• Turn off the ignition. 1 beep will sound.
• Quickly (within 5-6 seconds) turn on the ignition for 2-3 SECONDS !
• Turn off the ignition . THE KEY IS IN THE LOCK. 3 beeps will sound + the “car with key” icon goes out. We do not remove the key.
• Remove the key.

To check the operation of the immobilizer, simply start the car and see if the “car with key” icon lights up. If it is not lit, then the immobilizer is activated!

You can also remove the tag from the key and try to start the car. The immobilizer should not allow the car to start.

It may seem complicated at first glance, but in reality everything is simple. I got it right the first time. The video below shows my activation process.

If the engine does not start even with the tag, then there may be problems with the immobilizer itself or there are problems with the engine control system.

Video instruction

Especially for our portal, I made a video in which I activate the immobilizer on my Grant. Thank you, don't thank me!

Lada Granta Grantasalt + LADA.CC › Logbook › Fault No. 9 (immobilizer)

I spent the whole day igniting the doors (previous post), finished the installation... Got into the car.. key in the panel.. and oops! won't start! The immobilizer icon is lit on the dashboard. The car won't start?! I decided to reset the battery terminal for a couple of minutes to clear the error... It won’t start?! I began to blame the alarm for the fact that the fuse had blown and froze and blocked the fuel pump... I dismantle the entire beard, disconnect all the wires from the signal - it won’t start?! All the relays and fuses have worked, the starter, the fuel pump, and the ignition - everything works separately, but the car won’t start?! First, they tortured the family electricians over the phone) Then one of them arrived at the place around 10:00, climbed into the light of an LED flashlight and checked everything himself. He expressed the problem - there is no signal to the fuel pump, the fuse on the ECU has blown! We must look for him. The time is 24-00, we decided to resume repairs in the morning. I disconnected the battery terminals to reset the error, took a taxi home... The morning of the evening became wiser))

I arrived in the morning by car, connected the battery terminals and was already happy... I felt sad, the car wouldn’t start. It all started again. We checked all the locks and fuses, tortured another 5 hiccups in phone mode! electricians)) Everyone has the same answer, look for the fuse on the computer, it’s blown. I started climbing through all the blocks and boxes and found more fuses near the battery. It turns out the power) There I found a burnt out F5 (low beam headlights). The ring just burned out at the time ((We went to the store and bought it for 30 A. They replaced it - nothing starts, but the starter is already spinning on its own! I remembered the INJECTOR! Whose car I had the chip in. I called him. He explained that the immobilizer light was on, but the controls are turned off and the car won’t start, he arrived 20 minutes later because he lived nearby. He connected his ECU instead of mine and the car drove away! Happiness! How nice to hear that your half of the soul is ALIVE! He took my ECU. He arrived an hour later. Took off my immobilizer, he cleaned everything and filled in a new schedule that I just wrote. While trying to start the car, he decided that it was stolen! He probably opened the doors all day and inserted some kind of battery. He didn’t turn on the music at all! Now I understand the difference between electricians and They did not pay attention to the immobilizer icon, tore it off and climbed into the abyss in the old fashioned way, gradually eliminating all the affidavits!

Here's something else I'd like to add to this post, save it just in case: Grant Fuses

Now I see no point in activating the immobilizer, so in a minute the thief will open the passenger door, transfer the terminals to his ECU and calmly start the car.

look for fuses on the engine control unit

so i found a block

burned these 4 pieces

Concept of a locking system

An immobilizer is a special type of device, the main function of which is to block unauthorized activation. In other words, such a system will protect against theft of a vehicle, namely the Lada Grant. There is a small chip in the ignition key; once you activate it, a code is sent to identify the owner and the engine starts. The control program is designed so that the vehicle’s protection is activated once, that is, it is not possible to return everything back.

It should be noted that the immobilizer is a device that is able to identify its own lock, as well as control the supply of fuel, steering, engine power, and gearbox shifts. It quickly triggers and instantly “locks” the vehicle from an ill-wisher if the set parameters do not correspond to the specified ones at all (mostly we are talking about a password, but many car models can only respond to the fingerprints of the owner).

When purchasing a travel assistant, an employee in the cabin with the owner activates the immobilizer. If the owner does not want to connect it, then this is written down in the service book in case of disagreements and unforeseen situations on the part of the buyer.

If in a year he wants to turn it on, he will have to carry out a certain algorithm of actions. The owner will have two devices to open the car, one is black and the other is painted scarlet. The first one is necessary in order to turn on the ignition in the Lada Granta, the red one helps with entering the primary one, it must be hidden in a safe place so as not to be accidentally lost and taken only in case of emergency. If the red key is lost, the vehicle warranty received from the car dealership becomes invalid.

Equipment

The Lada Granta is equipped with two keys, the black one is considered the main and working one. In addition, it may also have a special remote control, which helps to remove the start ban. It is necessary to power the vehicle.

Red acts as a trainer. Its main functions are to operate the vehicle, as well as the training mode of the protection and door locking system.

Is it possible to do without an immobilizer?

There is an opinion that such a device is buggy in most cases, but this is hard to believe, since they almost never break down, unless, of course, they were installed by an experienced specialist. Remember that with its help you can protect your car from theft, although you should not be 100% sure of such security, since risks still exist.

Principle of operation

The main advantage of an immobilizer over an alarm system is its ability to break the chains necessary to start the car and prevent it from moving, while an alarm system can only report theft. Even if a thief turns off the alarm and gets inside the vehicle, he will not be able to start the engine and drive away.

There are models of anti-theft systems that allow you to start the engine and even drive several hundred meters, and only then block the vehicle’s movement.

Practice shows that such systems help not only protect the car, but also catch the criminal.

It is impossible to find out how the immobilizer works by the appearance of the car or keys, so it is almost impossible to bypass the system.

All modifications of Lada Granta are equipped with an immobilizer of the first type, which blocks the ignition when opened with someone else’s key or in the event of a break-in. Anti-theft protection is built into the control module of the electric motor and its components. It includes:

• 2 keys (the first is active, the second is training);
• control module;
• signaling device;
• communication coil in the ignition switch.

The system control unit houses a sensor, and a chip with a code is located on the key. The system reads the code and thereby allows or prohibits turning on the engine. The control light indicator is located on the instrument panel and signals the protection position. The model is also equipped with a door lock, which is controlled from the key fob: activated by a single click and deactivated by a double click.

Anti-theft protection operates in 2 modes:

• The immobilizer option is deactivated. In this case, there is no connection between the protective system and the electronic control unit, and the engine is not blocked when started by a third party.
• The function is active. In this mode, starting the engine is possible only with a valid key. If you try to start the engine in another way, the ECU is blocked.

Activation rules

Before this process, it is important to close the car doors and remove the keys from the ignition and wait six seconds. If nothing is forgotten and all actions are performed in a synchronized sequence, you can pay attention to how the red light starts and lights up, the immobilizer indicates the correctness of the actions. After this, the owner has no more than seven seconds to remove this key and replace it with a black one in the ignition. It is important that sound signals are emitted during this process. If this is not observed, the entire procedure must be started again.

Where is it located and how to activate it

Lada Granta cars are delivered to showrooms with the immobilizer function deactivated. Salon specialists perform activation at the time of sale, in the presence of the client. Sometimes salon employees forget to do this, or the buyer himself refuses to connect the protection. The vehicle owner needs to know where the immobilizer is located and how to make it active.

The brain of the anti-theft system is located directly in the ignition unit, which allows you to read the owner’s special code from the key. To activate the immobilizer, you need to perform the following sequence of actions:

• close the hood, trunk and all doors in the car;
• insert the training key (with a red mark) into the ignition and turn it until the ignition is activated;
• wait 6 seconds until the light on the instrument panel starts flashing;
• within 6 seconds, remove the training key and insert the working key, start the engine with it.

If everything is done correctly and on time, then this will be followed by 3 signals, and then 2 more. If there is no sound, the operation should be repeated again.

Anti-theft and signaling device

Many car enthusiasts, in particular Lada Granta owners, at the same time plan to make their vehicle universal, which means they plan to connect an alarm system in addition to the immobilizer, but won’t this lead to problems? It should be borne in mind that thanks to the latter, the engine starts automatically. What to do if the immobilizer does not allow you to turn on the engine without using the appropriate key?

There are several basic options, for example, do not remove it and let it be there permanently. But be that as it may, it is important that the immobilizer and the crawler in it are located in the car and have a special decoding chip. Many people recommend making a duplicate key so that it is always nearby.

The bypass block comes into effect when the transport starts. In the event that the vehicle is activated without a key, the engine is blocked. We must not forget that the simultaneous use of alarm and control significantly increases the price of CASCO insurance.

It is a well-known fact that equipment sometimes malfunctions at certain and most inopportune moments, and most new products break down, and the Lada Granta is no exception. For example, on the highway you can meet unfortunate drivers who find themselves in an unpleasant situation: the car does not start because the protection is blocked and there is no help for them, especially if they are far from the city limits.
