Properties of the Lada Granta

Despite the fact that
the Lada Granta occupies the sector of economical cars, it still costs a lot of money, and no one wants to lose it in case of theft.
In addition, any car in inexperienced hands is a source of inflated threat, which can threaten the thief driver, passengers and pedestrians with serious troubles. To avoid possible problems, various anti-theft means are installed on cars. The main elements are an alarm system and an immobilizer. Each of these devices has both pros and cons. The alarm system provides the car owner with some additional functions that increase comfort, for example, opening only the door on the driver's side or only the trunk, auto start, which allows you to start the car to warm up without leaving home. But the alarm system only notifies the owner of the car about penetration inside, while the immobilizer specifically prevents theft.

The immobilizer is an electrical controller that prevents the car from starting if the ignition was not started with the original key. A chip is integrated into the ignition key that sends the car owner identification code to the electrical control unit every time you try to start the engine.

Immobilization bypass procedure for Lada Granta cars

Question: How to deactivate the immobilizer, if necessary? That is, is it possible to activate and deactivate as needed?

Answer: Yes. You need to register your secret code in the ECM, and if suddenly a problem with key identification suddenly arises, you can use the service mode and start the car using the code (which was previously entered into the ECM memory).

Immobilization bypass procedure for Lada Granta cars

This procedure is used to start the engine without reading the code key in the event of a malfunction of the immobilizer. The algorithm for performing immobilization bypass is recorded in the non-volatile memory of the engine control system controller (ECSC). You can use the immobilization bypass procedure only after recording an individual numeric code (password) in the ICS. The car owner can change the password an unlimited number of times by entering the numeric code into the ICS. Initially, the KSUD is supplied with no programmed password, i.e. bypass procedure is prohibited.

1 Entering a numeric code into the KSUD

1.1 Prepare a set of ignition keys consisting of a working key (with a completely black head) and a training key (with a red insert).
1.2 Close all car doors. Insert the learning code key into the ignition switch. Turn the ignition on and off. The system status indicator (LED) should flash quickly. 1.3 Until the LED blinking stops (within 6 s), remove the training key from the ignition switch, insert the working key and turn on the ignition. The buzzer on the anti-theft control unit should emit three beeps. 1.4 Wait with the ignition on until the buzzer emits two more sound signals, then turn off the ignition. 1.5 Until the LED blinking stops (within 6 s), remove the working key from the ignition switch, insert the learning key and turn on the ignition. 1.6 The buzzer should emit three beeps. Wait with the ignition on until the buzzer emits two more sound signals. 1.7 Turn off the ignition without removing the training key, wait until the buzzer gives a single sound signal. The LED should blink twice as fast. 1.8 Turn on the ignition with the training key while the LED is flashing. The Check Engine (CE) light should be on. 1.9 Wait 1 minute until the CE goes out. 1.10 Enter a six-digit code number consisting of numbers from 1 to 9 (the minimum possible number is 111111, the maximum possible is 999999). 1.10.1 Entering a code number: press the accelerator pedal all the way, hold the pedal pressed for no more than 3 seconds. The number of presses on the accelerator corresponds to the entered number. The CE lamp lights up to confirm each press. 1.10.2 Recording a code number: press the accelerator pedal and hold it down until the CE lamp goes out (? 5 seconds). Release the accelerator pedal. * 1.10.3 Enter the remaining five digits of the code following the steps in paragraphs. 1.10.1, 1.10.2 5 more times in a row. 1.10.4 If, after entering the last digit of the code and holding the accelerator pedal pressed for more than 5 seconds, the CE lamp: - does not go out, then the password entry has been completed correctly; — starts blinking at a frequency of 1 Hz, which means an error occurred when entering the password. You need to turn off the ignition and repeat the procedure again from step 1.2. Attention!
If, after entering the code number and holding the accelerator pedal down for more than 5 seconds, the CE lamp begins to flash at a frequency of 1 Hz, it means that an error occurred when entering the number (for example, you pressed the accelerator more than 9 times or exceeded the waiting time (1 minute) even once without pressing the accelerator). You need to turn off the ignition and repeat the procedure again from step 1.2. 1.11 Exit from the password recording mode in the ICS occurs when the ignition is turned off. If entering the password is not completed completely, it is not saved. 1.12 The immobilization bypass procedure is prohibited if, after performing steps 1.2...1.9, you press the accelerator pedal and hold it pressed for more than 5 seconds. If the immobilization bypass procedure is prohibited, the CE lamp will remain on continuously with the ignition on all the time until the engine starts.

2 Perform a walkthrough

2.1 Turn on the ignition. The control system prohibits the engine from starting (the immobilization function is enabled). CE is constantly on. 2.2 Wait 1 minute until the CE goes out. If this does not happen, then the procedure for bypassing immobilization in the CSUD is prohibited. 2.3 Enter your password code in accordance with clause 1.10 (see above). 2.4 If, after entering the last digit of the code and holding the accelerator pedal pressed for more than 5 seconds, the CE lamp: - does not go out, it means the code was entered correctly, you can start the engine. — starts flashing with a frequency of 1 Hz, which means the wrong password has been entered, the bypass procedure must be repeated, turning off the ignition, starting from paragraph 2.2 2.5 If the bypass is performed correctly and the engine starts, the CE lamp goes out after the engine starts. 2.6 The CSUD operates in the immobilization bypass mode until it is completely turned off, which occurs 5 seconds after the ignition is turned off. The engine can be restarted if no more than 5 seconds have passed since the ignition was turned off. If more than 5 seconds have passed since the ignition was turned off, then starting the engine becomes impossible and the bypass procedure must be repeated again.

Advice for motorists

1. Any protection system is always better than none. Therefore, if it is possible to install an immobilizer, it is better not to delay its installation.
2. Car thieves have long learned to deal with alarm systems, and are gradually finding methods to neutralize the immobilizer. Yes, it's difficult, but it's possible. Owners of simple standard systems, in which all elements are located in predetermined places, suffer especially often.
3. The conclusion from the previous paragraph is this: the more complex the immobilizer, the greater the chance that it will actually protect the car. At the very least, it will not be easy to deal with him, and there is every chance that the criminal will give up this idea and switch to a “more compliant” car.
4. A delayed-action immobilizer gives a greater chance of preserving the car, since it is triggered unexpectedly and at the moment when the thief has already entered a busy street.
5. A certain guarantee that the immobilizer will work for a long time and without failures is provided by the quality of the device itself (here it is better not to skimp on brands) and the direct hands of the master who installs it. Therefore, it is more advisable to contact specialized service centers, where they provide a guarantee for high-quality work. The service life of the device as a whole depends on how the wires are laid and the relays are connected.
6. During installation, you can find out in advance how to safely disconnect the battery from the general network, what to do in case of failures, which crawler to install and whether it is needed at all. There’s no shame in asking questions to the mechanic; it’s bad to then stand over a “dead” car and figure out how much a tow truck will cost.

Connection

The red wire is the power plus, connect to a circuit that contains +12V voltage when the ignition is on.

Black wire - negative control input (70mA). When a negative potential is applied to this input, the code of the standard transponder key is read. Connect the black wire to the remote start system output that provides chassis potential while the engine is running.

Gray wires - depending on the configuration, connect to the external loop antenna installed around the ignition switch, or wind the antenna from several turns of wire over the standard RFID antenna.

Alarm compatibility and immobilizer problems

Often, Lada Granta car enthusiasts want to install an entire anti-theft system on their own car, or simply have the opportunity to use additional alarm options for comfort. One of the most useful alarm features is engine auto-start. But what to do if the immobilizer does not allow you to turn on the engine without the key in the ignition?

You can either leave it inside, or take a different route and make an immobilizer bypass block. The immobilizer bypass must always be in the car and contain a decoding chip inside it; one of the keys or their chips must always be in the car's interior. Experts advise making an additional key specifically for autostart.

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.

What will you need for installation?

Standard set of tools for installation:

• screwdrivers with Phillips and flat blades;
• a set of spanner or socket wrenches;
• knife for stripping wire insulation;
• soldering iron with a power of 20-40 W;
• solder and flux for soldering (it is prohibited to use soldering acid as a flux);
• insulating tape;
• double-sided mounting tape;
• electronic tester (multimeter);
• control LED with a connected additional resistance of 1 kOhm;
• wire with clamp;
• wire with probe.

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.

Purpose

Making a caterpillar with your own hands - photos, drawings, recommendations

The StarLine BP-03 module is designed to automatically disable the standard RFID (Radio Frequency Identification) system when starting the engine remotely.

The RFID system is used on most modern cars. A transponder is built into the car's standard ignition key, the code of which is interrogated when the engine is started with the key. If the engine is started remotely or automatically, this system will not allow the engine to start. The VR-03 module is designed to solve this problem, automatically transmitting the standard transponder code during remote engine start.

To operate the BP-03 module, a spare key with a transponder is required, which can be ordered from the supplier of cars of this brand.

Alarm compatibility and immobilizer problems

Often, Lada Granta car owners want to create an entire anti-theft system on their car or simply be able to use additional alarm options for comfort. One of the most popular alarm features is engine auto-start. But what to do if the immobilizer does not allow you to turn on the engine without the key in the ignition?

You can either leave it inside, or take a different route and create an immobilizer bypass unit. The immobilizer bypass must be in the car and contain a decoding chip; one of the keys or their chips must always be in the car's interior. Experts recommend making an additional key specifically for autostart.

The bypass block is activated only during an autostart attempt. If you plan to start driving without the main key in the ignition, the engine will be locked. It should be remembered that the use of a remote-controlled alarm system significantly increases the cost of CASCO insurance.

Everyone has long known that technology is imperfect; even the latest developments in the field of electronics can fail during operation. You can often see drivers on the highway with emergency lights and a squealing alarm - the car has stalled, and the immobilizer has failed and does not allow the engine to start.

One of the most significant disadvantages of an electronic anti-theft device is the total blocking of all vehicle systems for no apparent reason or the loss of certain functions. For example, window regulators and an electronic control unit fail. After several unsuccessful attempts to activate the controller, the car stops responding to the keys.

The easiest way to resolve such problems is to disable the immobilizer. This is doable, although you may run into the claim that the controller is activated once and for all. You can disable the “immobilizer” only if you have a red key containing a code. There are software methods for disabling it, but you should not use them yourself, as they require special skills, knowledge and technical support.

In any case, the shortcomings of the electronic anti-theft device are compensated by its usefulness. Safety is not something that can be neglected, and if the standard Lada Granta immobilizer does not suit drivers for any reason, you can always find alternative options.

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.

• Immobilizer bypass
• Installation of Lada Granta radio
• Immobilizer Needle

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.

Price issue

Below is a table with models and prices for common immobilizer models. Prices are relevant for Moscow. In other cities of the Russian Federation the price may differ.

When installing additional relays and control units, the installation cost increases by 3600-5100 rubles. Immobilizers under the Prizrak brand are not supplied for retail sale, but are sold only together with the installation service in specialized centers.

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.

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.
