We teach the immobilizer key for the Lada Priora with our own hands (video inside)

Often, owners of LADA cars lose the red training key or buy a car without it. And there comes a time when one single key with buttons fails and the car stops starting. If you have a red key, everything is solved simply - we buy a new key, swap the blade from the old one and train it using the red key. But if there is no red key, then a problem arises that can be solved in 2 ways: 1- disable the immobilizer completely 2- restore the “red” key.

The client chose the second option. And so in order, we dismantle the ECU, connect it on the table, reprogram it to learn a new red key and put it in place.

We throw out the non-working board from the old key

and glue in the prepared chip of the new red key.

Next, according to the standard procedure, we register a new switch key using a new red key.

As a result, the standard immobilizer was restored and the central locking buttons on the new flip key are fully functional.

If you have problems with the immobilizer on any VAZ car, please contact us. Quick repair, key restoration or immobilizer removal. We always have keys and blades for VAZ cars in stock - we will cut the blade and register a new key in the shortest possible time.

The principle of operation of the immobilizer in Priora

The anti-theft immobilizer allows you to start the engine only after recognizing the key installed in the ignition switch.

The operating principle of such a device looks like this:

1. There is a special identification chip in the head of the key.
2. The signal from this chip is sensed by a ring antenna made of many turns of thin copper wire.
3. The antenna is located around the ignition switch cylinder.
4. The read signal is transmitted to the control unit, which compares it with the reference one and activates or prohibits starting the engine.
5. The immobilizer unit is connected via the K-Line bus to the fuel pump control unit, engine ECU and ignition system.
6. If the key is not recognized, these systems are blocked. In this case, the crankshaft may be cranked by the starter, and the immobilizer system warning icon will light up on the instrument cluster.

How to get a new key without having the old one as a sample?

Here again, different options are possible.

1. You go to the official dealer with all the documents for the car, if, of course, the car was bought new, and ask him just one question: I lost the car keys, what to do. In response, he will most likely offer you to make a new key based on the parameters of your car and/or its serial number.
2. You change all the lock cylinders, including the ignition switch.

Pros: Thieves will not be able to use your lost keys to steal your car.

Disadvantages - it is expensive, difficult and time-consuming.

1. You call all the reliable companies involved in the production of keys, check whether they can produce a duplicate without the original, if they can, determine for yourself the most optimal price-quality ratio of them, remove the ignition switch and deliver it to the desired address, again along with the documents to the car. There they will make a cast of the lock and use it to make a duplicate; the only reason when this action will be denied to you is when the key is not a simple one, but a chipped one.

How to activate the immobilizer?

Before starting use, it is recommended to activate the immobilizer.

In order to do this, you must follow these instructions:

1. Take both standard keys, get behind the wheel and close the door behind you.
2. Insert the key with the red mark (training) into the lock and turn on the ignition.
3. After six seconds, turn off the ignition system. The indicator lamp in the instrument cluster will flash approximately 5 times per second, which is a sign of a normal learning process. If this does not happen, there may be problems with the immobilizer system or faulty components.
4. While the warning light is flashing, you must remove the red key, insert a regular key into the lock and activate the ignition. This procedure should be completed within six seconds. The buzzer will confirm that the training has been completed correctly with three short beeps.
5. Wait another six seconds, after which the buzzer should sound two additional signals. If this does not happen and the warning light stops flashing rapidly, then the learning process has failed and should be started again. If re-learning is also unsuccessful, then you should look for a malfunction in the system or key, which could have been previously trained for a different immobilizer.
6. If training is successful, turn off the ignition. If it is necessary to train additional keys, then such actions are performed with each one.
7. If you do not need to register additional keys, then immediately after the sound signals you must turn off the ignition and remove the regular key and replace it with a red one.
8. Turn on the ignition and receive confirmation in the form of three beeps with the buzzer.
9. In six seconds, two more signals should pass. After this, you can turn off the ignition, but do not remove the key from the lock.
10. Six seconds after turning off the ignition circuits, the buzzer should sound once and the flashing frequency of the lamp should increase.
11. After this, turn on the ignition (within 5...6 seconds) using the red key and turn it off after three seconds.
12. After a few seconds, the buzzer should sound (three beeps) and the lamp on the instrument cluster should go out. The ignition can be turned on again no earlier than after 10 seconds. When using some controllers, sound signals may appear immediately when the ignition is turned off.

Problem Resolution

What to do if the immobilizer blocked the engine from starting? First of all, make sure that it itself is functioning normally - the indicator on the dashboard (if there is one) indicates that the chip code is not recognized. If the indicator “shows no signs of life” when you turn on the ignition, then you should probably start by checking the electrical system - perhaps the fuse has blown in the section of the circuit where the immobilizer unit is powered.

Re-register a key that is not recognized by the system - this solves the problem. However, there are two ways to program the immobilizer. In the first case, which is used on most foreign cars, programming of key codes is carried out by a dealer diagnostic scanner, via an internal network (the request goes to the manufacturer’s servers). The entire set of keys is registered at one time, since at the beginning of the training procedure, data on previously registered keys is erased from memory. So the owner himself cannot do anything with the immobilizer: he turns to the official dealer of his brand or to a company specializing in such work. As a matter of fact, the existence of universal devices for training immobilizers “plays into the hands” of car thieves. And you should approach the choice of a company offering immobilizer training services more carefully - the car owner will not control how many keys are actually registered, and there may be an “extra” one for the future.

The second method of training the immobilizer involves the presence of a master key in the kit, which is used to program the others. This allows the owner to perform immobilizer training himself, but only if the master key itself is recognized. For example, the APS-6 unit, which is very familiar to VAZ owners starting with Kalina, has a similar learning mechanism.

You will also be interested in:

To program “working” keys using a training key on the APS-6 unit, you need to:

1. After closing the doors, turn on the ignition with the learning key.
2. Wait at least 6 seconds, then turn off the ignition. The immobilizer indicator will blink rapidly, indicating the start of the learning procedure.
3. Insert the registered key into the lock and turn on the ignition. Do this before the immobilizer light goes off. The buzzer will beep three times, indicating that the chip in the key has been recognized and read. If the indicator goes off and there are no beeps, this means either that the ignition is turned on too late (repeat step 1 onwards) or that the immobilizer is faulty.
4. Wait until two more beeps sound. This confirms that the key code is stored in the controller's memory.
5. Repeat steps 3 and 4 for the remaining keys.
6. After turning off the ignition with the last key you registered, with a pause of no more than 6 seconds, you need to reinsert the training key into the lock and turn on the ignition. First, three beeps will sound, then two more.
7. Turn off the ignition, but do not remove the key from the lock until you hear a single signal. The blinking frequency of the immobilizer indicator increases. If not, go back to step 1 and try again. A secondary error will clearly indicate that training with this master key is impossible. Therefore, contact the service.
8. When a single signal is heard, you need to quickly turn on the ignition. The buzzer will sound three times and the immobilizer indicator will go off. After 2-3 seconds, turn off the ignition. The car will respond by flashing the hazard lights and beeping.
9. Remove the learning key. Before checking the operation of the registered key, wait at least 10 seconds.

The procedure looks complicated, but it ensures that the user cannot accidentally trigger relearning by simply using the master key to turn on the ignition.

In some systems without a master key, the manufacturer provides emergency PIN codes for key programming. On old Renaults, the PIN code is calculated through the Trantir program using the code printed inside the key body; on Kia/Hyundais up to 2007, it is determined by the last digits of the VIN, even without special programs (online services), and so on. The code entry itself is performed both by standard means of the car (Renault has an interior door lock button) and through the diagnostic connector. In this case, you will have to buy an adapter for old cars with inexpensive devices like VAG K-Line from Aliexpress. You can find the necessary software on the Internet. The already mentioned Kia/Hyundai uses the Cascade program, in which the immobilizer learning process is interactive and placed in the corresponding menu item.

What is an immobilizer for?

In addition to protecting the car from theft, the immobilizer performs a number of additional functions:

• the ability to control the delay for turning off the interior lighting;
• control of the rear fog lamp;
• checking the presence of the key in the ignition when opening the doors and giving a warning signal to the driver (one buzzer flashes in the instrument cluster);
• signaling that the external lighting is not turned off when the ignition is turned off (double buzzer signal).

How to disable the immobilizer

If the immobilizer breaks down or malfunctions, the car owner is faced with a choice: replace the control unit or disable the system. A more rational solution, from a security point of view, would be to purchase a new control unit and keys, but there is no guarantee that this unit will last long. Another solution would be to deactivate the system. To disable the immobilizer unit, several methods are used that will require the performer to have knowledge in electronics. If you do not have such skills, then it is wiser to take the car to a service center, where the unit will be turned off by qualified specialists.

Using a crawler

A bypass device is often used when installing alarm systems with auto start. The operating principle of such a device is based on the use of a separate unit with a standard key or chip installed inside. The unit is located in the car interior under the plastic trim of the pillars or in the instrument panel.

The signal from the key or chip is read by the unit's antenna and transmitted to the ignition switch. The crawler is controlled using a separate relay. If necessary, the crawler can be set to permanently exclude the immobilizer from the circuit. The car can be started with a key without a chip, but data will be supplied to the immobilizer from the bypass device control unit.

One of the classic devices is the Starline crawler model BP-03, which can work in conjunction with any security alarms. Device connection options are shown in the photo below.

In addition to the key crawler, you can use keyless devices that emulate the signal from the chip. The operating principle of the devices is the same. The main disadvantage of this scheme is the retention of a standard immobilizer on board, so this option can only be recommended if security systems with auto start are installed.

Without a lineman

If the car owner does not want to install the crawler himself, then he can remove the immobilizer only by reprogramming the ECM system units.

On some blocks you will have to change the layout of the elements, but on others - not. Such products include the ECM model M73 manufactured by Avtel.

Before starting work, you must remove the unit from the car and connect a standard K-Line type adapter according to the diagram below. You will have to make the transition wiring harness from the unit to the adapter yourself.

Connecting the M73 block

After this you need to proceed as follows:

1. Install the OpenBox software on your computer, run it and read the stock EEPROM firmware.
2. Save the factory EEPROM data for rollback to its original state (if necessary) and modification.
3. Download and install the HxD file editor and open the downloaded firmware.
4. Add a line consisting of two FF characters at the beginning of the text and save the change.
5. Load the corrected file into the block memory. You can use ready-made versions of untrained firmware that are publicly available.
6. Disconnect the unit and install it back on the car.

To disable the immobilizer in the January 7.2 block, it is necessary to assemble the following circuit (based on the K-Line adapter), where there is a positive wire switch that acts as an ignition switch.

ECM connection diagram January 7.2 to disable the immobilizer

Then follow the steps:

1. Install ChipLoader version 1.97.7 or newer on your computer or laptop.
2. Launch the program and select the desired block type.
3. Connect to the unit using the “establish connection” function.
4. Read EEPROM chip data.
5. Click the “delete IMMO” button, after which the program will automatically correct the data in the file.
6. Close the program window, disconnect the unit from the wiring and return it to the car.

On M74 type blocks the following must be done:

1. Disconnect the battery from the car.
2. Remove the connectors from the block.
3. Install a homemade harness on the block (according to the diagram below). The circuit should use a double switch, which will allow voltage to be supplied in stages.
4. Connect the circuit via the VAG-COM cord.
5. Connect the circuit to the battery.
6. Turn on the first key of the switch, through which the programming permission signal will be sent.
7. Run the WinFlashECU program on your computer, in the settings window of which you select the block type and data transfer speed (the speed should be set to the minimum).
8. Turn on the second key, after which a notification about the start of communication with the block will appear in the program window.
9. Save the standard firmware of the unit and EEPROM and replace them with new ones. The flashing time may take several minutes.
10. After finishing the firmware, turn off the program, power and wiring.
11. After connecting the unit to the vehicle's on-board network, it may be necessary to adapt the zero throttle position. To do this, perform engine braking several times from 4 thousand revolutions to a thousand in second gear.

It should be noted that all flashing methods require the owner to have knowledge in electronics and software. If you doubt your own abilities, it is better to seek help from a service center.

Find immobilizer

To manipulate the immobilizer, you need to know where it is located. The standard location of the device is the vehicle's lock tab. The anti-theft device is secured with one screw, so removing it is not difficult. The antenna connector is located deep in the car panel, right behind the rubberized steering column curtain.

Unlock methods

To unlock the immobilizer controller, use the following methods:

• reflashing the immobilizer controller;
• shunting of actuators;
• complete disabling of the immobilizer;
• installation of an immobilizer bypass;
• call to the dispatcher.

Flashing

To flash the immobilizer, remove it from the car, connect it to a computer or laptop using an adapter, and then use a special application (it is supplied with the immobilizer) to change the firmware of its memory. To perform this work you will need not only a computer, but also the ability to use a special application.

Otherwise, attempting to flash the firmware will result in damage to the device. In addition, you need to have a good understanding of the structure of the car and know where the IM (immobilizer controller) is installed. Therefore, this method is most often used by car service workers, because the average car enthusiast has neither the equipment nor the qualifications for such work.

In serious alarm systems (Starline, Pandora and others), the immobilizer is part of the security system. Therefore, it is impossible to independently reflash this unit without deteriorating the alarm system. However, on cheap alarm systems, as well as those installed from the factory, this method works successfully.

This method is suitable for those who are well versed in electronics, the structure of the car and know how to repair car wiring with their own hands. It is necessary to short-circuit the wires corresponding to the relay contacts, making sure that this manipulation does not disrupt the operation of the engine electronic control unit (ECU).

This method will also not work if the relays are tripped. In this case, shorting the contacts will only result in a blocking voltage being supplied to the corresponding terminal of the ECU.

This method is used if other methods are ineffective. To perform this operation yourself, you need to unscrew the CI fastenings, remove it and disconnect all contacts. Then you will have to adjust the operation of the ECU, perhaps change its firmware. After all, the operation of the ECU depends on CI commands, so simply removing the controller will not restore the operation of the motor.

The exception is simple models and a standard CI installed from the factory, which close certain contacts of the ECU or supply voltage to some terminals. If a more complex device is installed on the machine, you will have to make changes to the wiring and firmware of the ECU. It is better to entrust such an operation to a specialist, unless you are well versed in electronics, the structure of a car and similar devices.

The crawler allows you to deceive the ECU by applying voltage to the corresponding terminals or closing the necessary contacts. This device can be made in various versions:

• simple switch;
• secret button;
• electronic unit with GSM module.

Installing a crawler reduces the overall effectiveness of anti-theft protection, because an attacker can use it to drive away with your car. Crawlers with a GSM module are the most effective, because they respond to SMS containing a specific code and sent to the correct number. If you have installed a reliable security system (Starline, Pandora, Alligator and the like) connected to the dispatch service, then only specialists who have received the approval of this dispatcher should install the immobilizer bypass. After installation, you must inform the dispatcher about connecting a new unit.

Call to the dispatcher

Modern cars are equipped with sophisticated electronics that control engine operation. Therefore, any intervention in the electrical wiring of the machine may result in serious damage to the ECU, which will require its replacement. If you are an automotive electrical specialist or an experienced radio amateur, you will be able to understand the immobilizer connection diagram and disable it without damaging the car.

Video

A video from the author Dmitriy Epishev demonstrates desoldering the microcircuit and resetting the data on the programmer.

The flip key for the Priora does not come from the factory - so you take a standard microcircuit and screw it into a new case: here you have a flip key. Such cases are usually sold on Aliexpress. You don't even need to re-program!

If the key is lost, then: it turns out that you can train any key for a Lada Priora car so that it is “recognized” by the immobilizer. Learning is as simple as pressing a couple of buttons.

When you buy a car, you are given keys to a Lada Priora with a diagram and three buttons and a regular mechanical one.

Making changes to your car for comfort is like an integral part of owning a car. The Lada Priora offers real scope for creativity, and many owners strive to make their “swallow” different from other cars. One of these conveniences - which, as a rule, does not come from the factory - is a flip key for the Lada Priora.

The standard ignition key is “learned” from the dealer or car service center, and the car owner most likely does not do this on his own. Because of this, learning the flip key for the Lada Priora can be difficult. With the necessary amount of patience, dexterity and dexterity, this procedure will become extremely clear, you just need to follow the instructions as clearly as possible.

How to change the battery in the Lada Vesta ignition key

Buttons consume energy, so you need to remember the battery charge and change it in time. The first sign of low battery will be a slow response when pressed. The Lada Vesta flip key is synchronized with a standard battery. To change it you need a screwdriver. The remote control opens with the blade extended, otherwise the case and microcircuits can be damaged. The tool is inserted into the hole in the center line of the case and with a simple movement separates the remote control into two halves. After changing the battery, you need to use a light snapping motion to assemble the product.

Regular key with buttons

The standard device that is sold with the car is the usual, “basic”, simple version. Inside the case there is a board that includes a control panel for some vehicle systems. In Priora, the key is not just a tool for manually opening doors, it is a pocket device that simplifies the operation of the car.

The remote control control board is attached to the key blade, which is inserted into the ignition switch. The design of this tool is a little flimsy, so due to the swing of the blade, the remote control board suffers and does not respond to button presses the first time.

A standard unit, like any other, operates via a radio channel and a transponder channel. The first sends commands to the driver's door module and the electrical package control module, which is located behind the center console. The second channel transmits signals with the immobilizer control unit APS-4 or APS-6.

Key programming for Kalina, Priora, Grants, UAZ and Niva

The remote control key for Lada Priora, Kalina, Granta, UAZ Patriot, Niva is programmed on the car without any devices. To do this, you need to have a so-called training key in your hands - which has a red pip on the head of the key. Used in cars with APS-6 unit.

IMPORTANT ANNOUNCEMENT.

We work and consult ONLY in Nizhny Novgorod. If you are from another region, do not write or call us - we will not answer. We do not treat keys or cars from other cities: contact specialists in your region.

Purpose - why to teach

Each car comes with two keys from the factory: one training key and one regular key without schematics. The device containing the microcircuit is trained to recognize the car and is installed as an immobilizer driver. After which an anti-theft alarm is installed. After this tricky procedure, they are both able to:

• Control door locks and trunk lid from a distance;
• Manage alarms;
• Manipulate power windows;
• “Contact” the immobilizer and unlock the engine control.

Training procedure

From the moment the engineer made the key for the Lada Priora, the demand for ECU reprogramming has increased significantly. You need to prepare for reprogramming the ECU and not do it chaotically: the sequence of steps must be completed without long breaks.

You can train keys by following the following procedure:

Close all doors. Make sure that the sensors on the control panel do not accidentally light up and interfere with the process: add several liters of fuel to the tank, remove faults, etc. Sound signals can confuse you. The vehicle's ignition must initially be turned off. For convenience, place the training copy in your right hand, and the first worker, who will be assigned a code in the ECU, in your left hand. Turn on the ignition with the training key (it is smaller and marked with a red plastic insert), wait at least 6 seconds.

Attention! In the entire algorithm, you never need to start the engine, that is, you do not need to turn the key all the way: you only need to turn on the ignition.

Turn off the ignition by turning the key towards you. After this, the yellow car icon will flash (very quickly) on the dashboard. This means that the ECU has authorized and started the key learning mode; it should flash until all actions are completed as a sign that everything is being done correctly. Remove the training tool from the ignition lock cylinder, quickly insert the first working key within the next 6 seconds and just turn on the ignition. A triple beep will sound (not a horn). After a few seconds, two more beeps will sound - this means the code has been successfully written: you can turn off the ignition! If there were no two beeps, it means something went wrong and you need to repeat it all over again. The last steps are to confirm the recording of the code for the new control panel. After the double signal, you can remove the working key, but then you quickly need to insert a small, training key. Turn on the ignition, then again wait for three or two beeps. Turn off the ignition, but do not remove the key! After a single beep, the yellow vehicle icon on the dashboard will flash even faster. Turn the ignition on then turn off after three seconds. Three more beeps will sound. Do not turn on the ignition for another 10-20 seconds. It's not always possible to get everything done the first time. For some Lada Priora cars, the sound signal may disappear - it is worth trying to continue the algorithm if the yellow car icon is still blinking. Training of the second instrument is carried out in the same sequence.

Replacing the battery of the Lada Priora remote control

The moment when the battery in the remote control needs to be replaced is determined by the fact that when you press any button (for example, when turning an alarm on/off), the indicator on the remote control flashes twice; If it doesn’t even blink, it means the battery has become unusable. During normal operation, the indicator should light up once.

The control panel contains a lithium battery (CR2032) in the flip key fob, the voltage is 3 V. To remove it, you need to open the case (the cover is secured with one screw) and carefully remove the board. Place a new battery taking into account the polarity; install the board back and reassemble the case. The electrical package will work in the same mode, the key fob code does not change.

Resynchronization of remote control codes

The ECU transmits data to the Lada Priora remote control via a radio channel and a transponder channel. Problems arise with the radio channel: if you press buttons (send a car signal) outside its coverage area, then after 1000 presses the code is resynchronized: while sending a command in the radio signal area, the electrical package will not perceive the remote control code.

Also, a code error may occur if the battery is discharged: in this case, the ECU will briefly generate a random code that will erase the codes of all remote control chips. In these cases, you will have to enter the remote control data into the electronic control unit again.

A flip key for Lada Priora is, first of all, beautiful. It is pleasant to the touch; all remote control buttons are located on the body. Its undeniable advantage is that it will not damage the fabric during storage, because its blade will be hidden. The blade is attached to it more securely, and it will not loosen the remote control chip.

Reliable protection against car theft

One of the most effective means against car theft is an immobilizer. This is an electronic device that blocks fuel injection in case of unauthorized access to the car. If the immobilizer is activated, then the Priora will not budge without a special permission signal.

As a rule, this signal can only be given by a special key that the owner of the car must have. If attackers decide to break the immobilizer, the car’s electronic systems will be blocked and the car will not go anywhere. So such a device is a very effective method of resisting car theft.

The presence of an immobilizer may be provided by the car manufacturer. This device is called a standard immobilizer. Although some car factories still prefer simple standard alarms, which do not prevent theft, but only notify the owner about it and scare thieves. All configurations of the Lada Priora contain an immobilizer, but it must be activated for it to work.
