Standard Priora alarm – Standard Priora alarm

Every Lada Priora buyer is twice lucky. The first time is when he becomes the proud owner of a modern Russian-made car. The second time is when he realizes that along with the car he also got a very good and reliable alarm system. He learned about this already in the salon during a demonstration of the possibilities of purchasing upon receipt.

The local manager activated the immobilizer and gave a brief overview of the standard alarm system of the Lada Priora. In the eyes of a new car owner, delight and bewilderment are possible. He had already purchased a new alarm system in advance and was mentally considering options for its use. Here you can’t do without advice from setup experts.

Why do you need to turn off the alarm?

The need to suspend the machine's security device is dictated by emerging circumstances. The main reason when you need to turn off a car alarm is its failure. The alarm may need to be suspended at any time. The device is turned off using a key fob or a special button with your own hands. Drivers’ knowledge of the shutdown procedure is a necessity dictated by emerging situations.

The car alarm stops functioning in a number of cases, then you need to turn it off. Alarm failures occur for the following reasons:

1. The security device is exposed to high-level radio interference. Car owners in large cities are especially affected. Interference with key fob signals comes from numerous electronic devices, power lines, and power electrical installations. The signal from the car alarm key fob increases as the distance between the transceiver devices decreases.
2. It's rare, but sometimes the car alarm key fob breaks. The situation cannot be ignored, just like when the batteries are dead, you need to turn off the security system. In this case, everything must be done with your own hands when there is no battery at hand.
3. Complete discharge of the car battery is one of the main reasons for the alarm to stop working, which is recommended to be turned off. In this situation, you should strictly follow the recommendations of the car alarm instructions.

These are the main situations when it is necessary to terminate the security device. Other emergency situations are possible that require the intervention of the car owner.

Principles of disabling car alarms

The car alarm can be turned off in two ways. To disable the standard alarm, it is recommended to use the factory method. To disable it, use the “Valet” service button. This is only possible if you know where it is located, located in secluded but accessible places:

• Directly at the gas or clutch pedals;
• In the area of ​​the fuse box;
• In the niches of the steering column;
• In accessible places on the front panels.

If it is impossible to identify the button in the indicated places to turn off the car alarm, experts advise referring to the instructions. For alarm management, this information is key and must be contained. To disable, use a combination of simultaneously pressing the buttons and one of the pedals or two.

If you fail to turn off the car alarm after several attempts, it may become blocked. The recommended time for holding the alarm button with the pedal pressed should be at least 10 seconds.

The next technique is a coded shutdown, without using a car alarm key fob. Modern devices use button and ignition combinations. Disabling steps can be done manually using several techniques. Details on how to turn off the machine alarm are described in the attached instructions for setup and operation.

This option uses a PIN code that is programmed in advance. The combination of symbols is known exclusively to the car owner. The PIN code is programmed with the ignition on and successive pressing of the emergency button. The number of times the button is pressed corresponds to the first or second character of the code.

When setting a PIN code for car alarms with your own hands, the maximum code value of 4 digits is allowed - 9999. In standard alarm systems supplied by manufacturers, the PIN code is not complicated. It is not difficult to disable the car security system. Therefore, experts recommend reprogramming the code using a much more complex combination of symbols. Linking to memorable dates is not recommended.

There are alternative options to disable the car alarm. One of them is the use of original software. In another, special crawlers are used to disable the alarm.

Disabling without key fob

Disobedience to a car alarm key fob is a rare precedent, but it does happen. The main reason is that the alarm system was assembled and installed with defects that appear over time. The car owner is faced with a dilemma - it is necessary to disable the security device without a remote control. This part of the text is devoted to turning off the system without using the control panel.

The reasons for disconnection can be indirect and objective. Indirect ones include inhibited actions of the key fob that occur due to wear of the remote control battery or accumulator. It is recommended to avoid using the remote control away from the machine.

Another reason when it is impossible to turn off the alarm is that the car battery is discharged. In this case, the owner takes measures to bring the battery into working condition. Next steps are taken with the car alarm.

Objective reasons include worn-out car alarms. In such cases, turning off the device is very problematic. To turn off the alarm, it is advisable to gain access to the service button, or try to turn off the power to the system.

Another reason is that the remote control has lost synchronization with the protection device. The problem can be solved by flashing the remote control yourself, according to the instructions, after first using the emergency opening of the car. How to turn off the alarm in an emergency was discussed above. In any case, there are two main options: car alarm emergency button; using a PIN code.

You shouldn’t give in to panic if you can’t turn off the car alarm at the right time. First of all, you need to remember the recommendations of the alarm operating manual. It is possible to disable it without a key fob, either with your own hands or with the involvement of service organizations. Access to the car interior is always possible.

Sensitively responding to market demands, automakers have created a special anti-theft system that is installed on the car directly on the assembly line. The Priora's security is asleep until it is activated by the owner. This is an immobilizer, or as it was called even more simply - an immobilizer, a standard alarm system of modern cars.

Signs of a faulty factory security system

• the car does not start;
• the electronic control unit does not respond in any way to pressing the key fob;
• the system does not work when hitting the surface of the body;
• constantly activated for no apparent reason;
• the doors are locked after pressing the open button.

Malfunctions are often associated with the design of the standard security system. Owners of domestic vehicles note that after several years of operation, the starter does not activate when trying to start the engine, or turns off after a few revolutions.

If one of the problems occurs, turn off the device, then contact the installers to diagnose and determine the cause of the problem. Before contacting the service center, test the system yourself, following the sequence of measures.

Priora standard alarm or immobilizer

In order to prevent car buyers from tampering with the elements of the car system, they did not install anti-theft alarm systems from third-party manufacturers, and developed a standard alarm system - an immobilizer. This system differs from all other types of security alarms in that it interacts directly with the Electronic Engine Control Unit (ECM) of a modern car. When a car leaves the factory, this computer, the electronic control unit (ECU), contains a special EEPROM security file. Only a coded signal from the APS unit (automotive anti-theft system) can turn it on. She sends this signal only after the activation procedure. After this, when activated, it becomes a full-fledged automobile anti-theft system.

For M-74, the process of turning off the immobilizer will look like this:

Disconnect the battery, disconnect the immobilizer control unit from the network. A harness with cables and a double switch is connected to the immobilizer. The circuit is connected to the battery and computer using a VAG-COM adapter. The first button of the switch is activated, it “gives the go-ahead” to change the code. The code is changed in the WinFlash program. First of all, in the settings you select the module type and the information transfer speed parameter. The second switch button is activated; it is responsible for communication between the computer and the immo control unit. The standard lock code is retained, and the Eeprom cell data is overwritten. The whole process takes a long time, but you need to wait for contact. Upon completion of the recording process, the control unit is connected back to the vehicle network, and the battery is started.

What does the standard Priora alarm system consist of?

Any standard anti-theft system consists of several elements, it includes:

• training key;
• key fob;
• signal receiver antenna;
• APS block;
• lock activators;
• sound signal;
• EEPROM section in the ECU.

Training key (transponder)

The key set includes two ignition keys. One of them is the so-called educational one. It has a built-in special semiconductor chip with characteristic magnetic radiation. It is inserted into a special recess in the end part of the key, closed with a red decorative cover. Because of this, such a key is sometimes called a red key. This element is necessary to activate the standard anti-theft system. And for using the car if the anti-theft is not activated.

Key fob

This ignition switch has a key fob built into the handle for a standard alarm, just like a regular car alarm. It has only three buttons:

Accordingly, when the APS is activated, each button performs its own function.

Signal receiver antenna in the ignition switch

To read signals from the training key and key fob, a special antenna is built directly into the ignition switch. It is made in the form of a kind of coil, and is connected to the APS electronic control unit. Its task is to read the key signal and transmit it to the block.

APS block

This is an electronic unit that receives a signal from ignition keys equipped with a chip, or key fob, and gives a command to the car’s computer, which controls the entire ECM system and allows starting and driving, via a special channel. In addition, the APS standard alarm unit transmits signals to the activators of the door and trunk locks, and an audible signal to sound an alarm. On the Priora, the APS unit is built into an additional electrical package control unit, that is, a unit that controls power windows, heating and rotating rear-view mirrors, and other additional devices.

Lock activators and sound signal

These devices (activators) in the standard Priora alarm system operate as a central lock, that is, when the driver's door is closed with the key, the latches of all doors are closed. They are in a locked position and cannot be opened by simply pressing the handle. Their principle is ordinary electromagnetic coils that move the lock lever, closing all doors upon a signal from the control key fob.

The usual type of sound horns are connected under the front bumper of the car.

EEPROM file

Just an area in the flash memory section of the control ECU. Upon receipt of a certain message, it is activated in the recorded program. From this moment on, all actions: starting, moving away, central locking are possible only with an activated key fob and a training key. Otherwise, this file blocks operation and turns on the standard Priora alarm system.

Principle of operation

The principle of operation of the standard Priora alarm, like any other, with reliable dynamic coding, is quite simple and understandable. The activated signaling system accepts for execution exclusively the commands of the native, trained chip installed in the ignition key of the Lada Priora. This will be followed by a series of logically related actions:

• the communication coil, having received a reliable encoded signal from the ignition key chip, forwards it to the standard immobilizer (IMMO) of the Lada;
• he, in turn, checks the received reliable, encoded signal with the code recorded in his memory;
• if they match, the immobilizer sends a command to the authorized engine start of the Priora ECU;
• The Lada ECU, having received a signal from the IMMO alarm, unlocks its electrical circuits;
• If there is an unauthorized attempt to start the Priora engine, the IMMO will not send a confirmation signal to the ECU and the control circuits will not be unlocked. In addition, a siren warning signal with light flashes will sound;
• in addition, the car key fob, built into the chipped ignition key, controls the central locking of the Lada Priora and its window lifts;
• By installing shock or volume sensors yourself, the alarm system receives an additional option to increase its reliability.

Important: be sure to require activation of the standard Priora alarm system when purchasing it. Otherwise, you will have to configure it yourself using a training key with a red insert. In this case, various nuances with its performance are possible.

Activation of standard alarm

When leaving the factory, the car anti-theft system installed by the manufacturer can be said to be asleep. In order to “wake up” it, or more correctly, activate it, you need to go through a special procedure for activating the standard alarm. This can best be done, of course, by a specialist at a service center. But in principle, this procedure is available to the owner of the Priora himself. You just need to write down the action algorithm on a piece of paper, prepare two keys, a training key and a key fob, get behind the wheel with all the doors tightly closed, and carry out the operation strictly step by step.

1. Use the red learning key to turn on the ignition for 6 seconds and then turn it off.
2. The warning lamp in the form of a key on the instrument panel begins to blink rapidly, about 5 times per second. It will flash all the time during the learning process. If the lamp stops flashing before the end of the process, it means an error has occurred and you need to start again.
3. Before 6 seconds have passed, with the ignition off, remove the red key and insert the immobilizer key fob.
4. Turn them on the ignition. If everything is in order, the panel buzzer will give 3 signals at once.
5. Wait another 6 seconds with the ignition on. The buzzer should croak 2 more times in a row, and you can turn off the ignition. Wait until the light on the panel goes out without removing the key from the lock.

How to turn off the standard alarm

It is very important to know that if the factory anti-theft is activated, it is simply impossible to disable it yourself. The file, having revived, will no longer fall asleep. The only civilized way to deactivate an armed and trained alarm is to remove the ECU from the car and either replace it with a new one that is not trained, which is very expensive, or give it to specialists for reprogramming. It is many times cheaper and more reliable. There is also a popular way to “deceive” a trained unit - when the chip is removed from the training key and taped with tape at the base of the ignition switch. However, it is worth remembering that this is a rather clumsy and risky method. The risk of failure of the Priora standard alarm program increases and, accordingly, there is a danger of its unauthorized activation at the most inopportune moment. Therefore, if it is activated, then it is better to use it, especially since user reviews about it are very good.

In the video you can watch the training process of APS “Priors”, “Kalina” or “Grants”, with two working keys:

Review of the standard alarm system on Priora

Cars from the Volzhsky Automobile Plant usually belong to the risk group of cars, theft of which is quite possible. This statement was equally correct for the “classical” models, and it is also correct at the moment.

At the same time, installing an expensive car alarm on a cheap car can hardly be justified. Therefore, many owners are completely satisfied with the standard alarm system that was installed on the car at the beginning. For example, the standard alarm system on a Priora will be able to provide the least amount of protection against theft and at the same time will not require additional costs.

It should be noted that a possible thief (or vandal) first pays his attention to cars that, upon first inspection, do not have any means of protection. If the owner, when leaving the car, traditionally locks it with the key, and the car itself does not greet its owner with blinking direction indicators, does not react to a blow to the wheel, or does not have a simple flashing light indicator, then such a car becomes an easy prey for scammers.

Reliability level

Undoubtedly, the standard alarm system installed and configured on the Lada Priora is simple, reliable and fully adapted to difficult local weather conditions. Properly activated, it leaves no doubt about its functionality. Besides:

• the quality of installation and configuration of factory alarms is guaranteed by experienced factory specialists and the control service of the enterprise;
• The key fob is integrated into the regular ignition key. There is no need to wear them separately in a whole bunch;
• there is no need to equip standardly installed equipment with anything;
• The factory alarm system of the Lada Priora is covered by the factory warranty;
• if the Lada owner wishes to install and configure an additional sensor, there is a spare port;

Unfortunately, if the factory, standard installation is a big plus of such an alarm, then at the same time it is also a significant minus. Thousands of analogues of such alarms drive Lada Prioras across the vast expanses of the country. No mystery for attackers. But they are not looking for cars with alarms, but without them at all. You also need to understand these immobilizers, and time is money. And unnecessary problems are not for the criminal business.

Alarm characteristics

After modernization, the Lada Priora received a device that plays the role of a basic alarm system and received the usual name for such devices - an immobilizer. An immobilizer (from the Latin to paralyze) is a device that, interacting with the electrical control unit, allows you to shut down the operation of the engine and provides unhindered access to the car and its systems.

By its very nature, the immobilizer security device presents itself in such a situation as a breaker of the electronic circuit that powers the car. And the driver, who has an active key with a microchip built into it, activates (turns on) or disconnects the power supply chain if necessary.

At the same time, installing the key in the ignition switch socket is not a connecting link, but only allows you to send a signal to the necessary electrical sensor so that the necessary devices do their job. Structurally, the immobilizer protective device consists of several blocks that are connected into a single mechanism:

Alarm activation

In order to activate the standard alarm, you will need a training and master key, which must be issued when purchasing the car. Be sure to pay attention to this, or in the future you will have to contact the dealer separately. You will need to carry out the following actions in the prescribed manner:

1. Fill the fuel tank (at least 10 l). This action must be performed so as not to get confused in the signals supplied by the immobilizer and to carry out the sequence of operations in strict accordance with the algorithm.
2. First of all, you need to use the learning key, which is inserted into the ignition switch. The ignition must be turned on for a certain time (about 6 seconds), and all doors in the car must be tightly closed. Correct actions can be monitored by a rapidly flashing (about 5 times per second) indicator lamp. After this, you can turn off the ignition and remove the learning key from the lock.

How to turn off the standard alarm?

The main reason when it is necessary to disable the standard alarm on a Priora is its malfunction. In such situations, the car unreasonably reacts by turning on the sound signal and prevents the engine from starting. Such a failure in winter conditions poses additional inconvenience. The immobilizer is not only an additional constant consumer of energy, but may simply refuse to work normally in severe frost.

At the first sign of incorrect operation, you should check the serviceability of the alarm control unit on the key fob. Perhaps the poor response to the signal from the key fob is due to a dead battery or the presence of radio interference in a certain place. In such situations, the control unit will only be able to receive a very close signal.

The inability to turn off the standard alarm system on a Priora from the key fob is not an obstacle to turning it off. In this case, you need to use a secret button, which, as a rule, is installed in the cabin or next to the control unit . Check this point when purchasing a car or at the station where the alarm was installed on the car. disable the standard alarm system on the Priora by first turning on the ignition. You will need to enter a secret code (PIN code), which must be known to each owner.

After turning off the alarm, you will also need to turn off its power. A possible malfunction may be a low battery charge level, as well as a very high current consumption by the immobilizer if it is damaged.

Starting the engine, bypassing the working unit of the standard alarm, is done by connecting power wires, bypassing the device relay. However, if you are not sure that the wires have been identified correctly, then you should contact a specialist.

Protection functions and operational reliability

The standard Priora alarm system is not overloaded with additional functions.
It does not have access to service options related to auto start, opening the trunk, or searching for a car in a parking lot. It will not inform its owner based on the indication from the key fob about the loss of communication with him. And even more so, it will not send all kinds of SMS messages about various machine malfunctions. Let the owners of Bugatti Veyron and Porsche 918 use GSM communication and GPS navigation services. It is absolutely not worth using a gas adjustable wrench No. 3 as a torque gauge. The standard Lada car alarms have a different task. They don’t need to amaze the Priora owner’s colleagues with the ergonomics of the control key fob or autostart from a neighboring village. Their advantage is reliability and ease of setup without additional hassle and the involvement of related specialists. In addition, during its operation, the standard alarm system ensures the safety of specific areas of the machine:

• doors of a protected vehicle;
• car hood or trunk door;
• driver's door with lock cylinder;
• voltage at the terminals of the standard battery.

Lada Priora will give a fairly reliable alarm signal and will accompany it with flashes of turn signals when attempting to violate any of the zones protected by the standard alarm system. Such unauthorized access attempts include:

• desire to open any of the car doors, including the trunk or hood;
• turning an untrained key in the ignition lock of the Lada;
• any manipulations with the standard battery related to its connection or disconnection;
• when an additionally configured volume or shock sensor is triggered.

Important: if cases of incorrect operation of the car’s standard alarm system occur, you should first of all check the serviceability of the control key fob.
