Central locking, central locking activators, problems. The central lock does not work: do-it-yourself repair How to repair the central lock of a VAZ 2114

During the operation of cars with central locking, the owner may encounter many breakdowns. In this case, malfunctions can be caused by a variety of reasons - high levels of humidity, extreme cold, wear, installation or adjustment errors. How is the central locking repaired if it does not work? What actions should be taken to localize the breakdown? These and other points require detailed consideration.

Design features and principles of fault detection

All central locking breakdowns come in several types:

  • Partial or complete loss of performance.
  • Mechanical damage.
  • Electrical defects (malfunctions).

In all cases, the central locking stops working or malfunctions, which leads to inconvenience for the car owner. To avoid wasting time, start with diagnostics. Determine why the central locking does not work, and then proceed to troubleshoot the problem. This approach speeds up the verification process and reduces potential financial losses.

The performance of the central locking does not depend on any additional factors (the engine is started or stopped, the ignition is turned on or off). The key condition for operability is the presence of voltage in the on-board network, which powers the control unit and actuators. In this case, the secondary circuit terminals must be on the car battery.

The central locking system includes the following components:

  • Electric drives in the form of solenoids. This mechanism is typical for central locking systems built on the electrical principle.
  • Vacuum drive, control board, compressor and group of tubes - equipment typical for pneumatic central locking systems.
  • Switches.
  • Conductors that connect the working elements of the system.

The activator (main drive) is mounted in the car door (driver's and (or) passenger's). When a corresponding signal is received, it sends a command to other drives to lock or unlock the locks installed in the remaining doors of the vehicle. So, in the case of an electric central locking system, the signal is sent to the power relays and the lock control unit.

If a security system is installed on the car, then the first step is to check that the locks are opening and closing. If the central locking system copes with the task, then subsequent checks are carried out. If there is no reaction when you press the portable remote control (the central locking does not work), check the device by pressing the key fob button or turning the key in the passenger and (or) driver's door lock. If the central locking system does not operate manually, look for a breakdown in the control or electrical circuit of the machine. At the same time, do not rush to start repairing the central locking - try replacing the battery (there is a high risk that it is discharged).

The central locking does not work at all or only partially works

If there are minor problems, or in the event of a complete device failure, determine the type of failure. So, if the car is equipped with an electric central locking system, then when the system is activated, the relay clicks will not be heard. In vacuum-type devices, the compressor may not work. In both the first and second cases, the locks on the doors remain in the same position.

Check the integrity of the fuse that powers the device. Please note that the number of fuses may vary depending on the electrical circuit used. If a faulty element is found, replace it. But remember that such a breakdown is often only the “tip of the iceberg”. If the fuse link burns out again, this indicates a short circuit in the system.

When the check shows that the fuse is working properly, but the central locking does not work, there are two possible reasons:

  • The voltage to the drive in the driver's door has disappeared. This is possible in the event of a wire break, or due to poor quality of the connection at the terminal caused by the oxidation process. In this case, the activator does not transmit a signal to other actuators in each of the doors.
  • The drive switch (limit switch) has broken down, the quality of the contact connection has deteriorated, or there is a wire break. In all the mentioned cases, the system does not receive a control signal.

Start repairing the central locking by measuring the voltage and checking whether control pulses are issued (voltage at the contacts). Afterwards, check the quality of the contact connections and the serviceability of the wiring in general. At the final stage, proceed to checking the limit switch. If the switch is acting up or is faulty, repair or replace the device. Finding the limit switch is not difficult - in electric central locking systems it is installed inside the activator.

Another reason for the malfunction is a malfunction of the alarm circuit or control compressor (for vacuum locks). Such work is carried out at the last stage of diagnosis due to the increased complexity and low probability of manifestation.

In a situation where the central control partially fulfills the tasks assigned to it, for example, a relay or compressor is triggered, then we are talking about a partial failure. The most common failure is incomplete opening (closing) of the door latches. This malfunction is often caused by malfunctions of the traction lock, which combines the lock and its drive part.

If the problem is with the main actuator, the problem will be diagnosed for all doors. In a situation where failures occur for one door, then diagnostics of the drive should be carried out in it.

How to eliminate a partial malfunction of the vacuum central locking system?

One of the common problems is prolonged operation of the compressor (longer than 15-20 seconds) until the protection operates. The problem is diagnosed as follows:

  • The central locking system works without stopping, closing and opening the locks until it turns off. Possible reasons are floating of the “plus” and “minus” due to the presence of condensation or deterioration in the quality of the contact on the drive. In this case, commands are alternately given to open or close the doors until the compressor is disconnected from protection. Inspect the switch, and if repair is impossible, replace it.

Also, to eliminate the defect, check the integrity of the lines that go to doors with a faulty activator. The problem is easy to diagnose - it reveals itself as air hissing. If you find a faulty tube, replace it. If the lines are intact, the problem is in the drive (for example, a diaphragm has ruptured). If you do not have a replacement part (drive or membrane), buy the lock as a set.

  • The device worked, but some door did not open or close. In this case, the voltage is not removed - the compressor hums until it turns off.

At the end of the article, watch a selection of videos.

The reasons are a violation of the tightness of the main pipes or the absence of a signal sent from the door to the control board. In the latter case, the signal does not arrive to the compressor and the latter continues to operate. Another situation is possible when a command comes to the circuit, but the latter does not react to the signal in any way and does not give a signal to turn on (turn off) the compressor.

Start repairing the central locking by checking the integrity of the electrical circuits. Start with the activators (drives) and end with the control board. To measure voltage you will need a multimeter or voltmeter.

One option is to compare each of the drives. If the indicators of only one activator deviate, we can talk about its malfunction. Then find a break in the circuit and repair the area. The weakest link is the door corrugations. If the wires are intact, then the reason lies in a failed limit switch. The solution is to repair or replace the device.

To install a new switch, disassemble the compressor unit and clean the contact connections from traces of oxidation. If the above measures do not help, check the integrity of the main board circuit. Perhaps it will need repairs.

How to repair an electric central locking system?

If the electric central locking does not work, then the approaches to repair will be different. The main weakness of such devices is their intolerance to temperature changes, as well as high humidity, characteristic of spring and autumn. At the initial stage, the breakdown manifests itself as malfunctions in the operation of the solenoids, after which the devices cease to perform their functions altogether. The best solution is to replace the device with a drive equipped with a motor. As a last resort, disassemble, clean and lubricate the part.

Reasons for partial or complete failure of the drive in one (group) of doors:

  • Relay failure.
  • Deterioration in the quality of the contact connection or open circuit between the drive switch and the power relay. Problems are possible here in any part of the chain.
  • Failure of the control board (if provided).
  • Broken wiring or poor contact on the solenoid or motor terminals inside the drive.
  • Burnt out motor winding or solenoid coil.
  • Damage to the drive gear or moving parts of the device. The first situation is relevant for devices with a motor, and the second - for all types of activators.

Start repairing the central lock by checking the functionality of the device after applying external voltage (directly to the drive). According to the rules, voltage is supplied to one of the wires, which is important for the closing command. To open the lock, the voltage on the wire is removed and applied to the other conductor.

After analyzing the results, draw conclusions about why the central locking does not work and what actions to take next. There are several options here. One of them is checking the drive and eliminating the breakdown. Another way is to monitor the chain with the control board and relays, followed by restoration of the damaged area. Most often, problems are caused by a broken wire between the body and the car door.

Central locking is a useful device that provides simple and quick unlocking and locking of car doors. Let's look at the reasons why this system may not function correctly or not respond to driver commands at all, and we will describe measures aimed at eliminating such malfunctions.

1 Central locking - types of malfunctions

Central locking (CL) is considered an auxiliary mechanism. At the same time, it is a key element of the safety system of modern cars. The locks we are interested in are divided into electric and vacuum (otherwise called mechanical). The first systems include various mechanisms with a motor or solenoids. The design of vacuum central locking systems is a little more complicated. They contain special drives (activators), a control board, a compressor and tubes.

The central locking system fails for various reasons. Its malfunctions are usually divided into several main categories:

  • the device is not functioning correctly;
  • The lock is partially or completely inoperative.

If the central locking system has stopped working or performs any actions with a delay, first of all we need to start diagnosing the equipment. Testing the system allows you to find out the cause of its failure as competently and quickly as possible. Here it is important to know the following. The central locking must operate with the ignition off and on, as well as with the engine running and stopped, provided that the power terminals of the vehicle's on-board power supply are connected to the battery.

2 Do-it-yourself system repair - the simplest cases

If it is impossible to open (close) the door of the car on which, using the remote control (key fob), we try to perform these actions manually - with a button or key. If everything worked out, the cause of the central locking failure most likely lies in malfunctions of the control and electrical circuits (or normal circuits). In some cases, the problem can be solved simply by replacing the battery in the remote control.

When the lock malfunctions or does not function at all even with manual control, we determine the nature of the failure. The following phenomena indicate a complete failure of the system:

  • Electric central locking. When using the ignition key, the system makes barely audible clicks, and the buttons of the locking mechanisms do not change their position.
  • Mechanical lock. When operated manually, the compressor does not make any sounds.

What to do in such cases? First, we check the integrity of the central locking fuses. If necessary, we replace burnt out elements with new ones. Perhaps this will be the end of the system repair. It is more difficult when all the fuses are working, but the manual central locking control does not work. In this situation, failure may be caused by the following reasons:

  1. There is no voltage at the driver's door drive input.
  2. The limit switch does not function.

Both malfunctions usually arise due to insufficient contact at the terminals of the supply electrical cables or a break in the latter. The problem is solved as follows. We activate the central locking, check the presence of voltage on the contacts, then analyze the integrity of the wires and the quality of the contacts. If necessary, we insulate the wires or change them. If the system does not work partially (opens or closes only one door, does not respond to all commands, and so on), its repair will require more time. More on this later.

3 Restoring the functionality of vacuum devices - all options

If the mechanical central locking in our car partially does not work, we begin to look for the cause of the breakdown in the compressor. It is this mechanism that most often causes the unstable functioning of the central locking system. The following phenomena indicate problems with it:

  1. The locks on all doors or only on one are closed (or opened), but the compressor continues to function (hum) until the standard protection automatically turns it off.
  2. Closing and opening of locks occurs spontaneously and lasts until the compressor automatically turns off.

The main cause of the first problem is a violation of the tightness of the vacuum line elements. We need to take a closer look at her tubes. If air escapes from them, we will hear a hissing sound. This means it's time to change the line tubes. The system may also not work due to a faulty control board that is unable to send a signal to the door drive. In this case, you will have to disassemble the compressor unit and clean all its terminals from oxidation. This usually helps.

If the board's functionality is not restored, it needs to be replaced.

The second problem almost always arises from the appearance of condensation in the system, which leads to a malfunction of the driver's door actuator limit switch.

Let's dismantle this element. We remove all existing condensate. If the situation has not changed, install a new switch.

  • There is poor contact (broken wire) in the electrical circuit in the area between the power relay and the limit switch.
  • The solenoid coil or winding on the motor has burned out.
  • The moving parts of the drive are worn out.
  • The cable at the solenoid (motor) terminals has broken.

    • These malfunctions lead to the fact that the central locking system does not close the doors (does not open them), functions unstable, and does not respond to all commands from the control panel. We need to check the integrity of these parts. And then replace the failed elements (coils, windings, relays, gears), or restore normal contact of the electrical circuit wires. Any more or less experienced motorist can handle such work without turning to car service specialists for help.

    If the central locking (CL) does not work, then the driver cannot get inside the car. The article discusses the main types of malfunctions, how to open doors in case of malfunctions, and also provides recommendations for repairing vacuum and electric central locking systems.

    [Hide]

    Types of faults

    The central locking system installed on cars has the same operating principle and a similar connection diagram. Before starting repairs, you should find out how to disable the central locking and diagnose the equipment.

    If the car has an alarm system, the central locking is controlled using a remote control - a key fob. When you press the keys, a signal is sent to the control unit and functions are adjusted. The activated central locking system opens the doors.

    The central locking system includes switches, connecting wires and electric or vacuum drives as common elements. Actuators are activators. The front doors have a central drive, which, when activated, sends electrical signals to close or open the remaining doors.

    Causes of malfunctions

    If the central locking stops working, you must first check the fuse box. Short circuits and various disturbances often occur in the central locking system, which leads to blown fuses.

    The central lock does not operate when the battery is completely discharged. To check, you need to open the central locking with the key and try to start the car. If it does not start, then the reason is the battery is discharged.

    The reason why the central locking system does not work may be due to a breakdown of the electronics. You can open the car without a key using the key fob. If the central locking does not open with the key fob, you should check the batteries and buttons of the key fob. They may stick and not work at the right time.

    At the next stage, using the instructions, you should check the alarm control unit. It is possible that due to problems with it, the central locking works, but does not close all the doors. The last thing to check is the microboard, which is located on the activator motor, and at the same time the drive itself should be checked. Defective parts must be replaced.

    Electrical circuit diagram for central locking

    If the central locking does not work, this may be due to mechanical problems: the cylinder drive hose is faulty. The signal received by the control unit from the key fob is transmitted to the motor on the doors, which should operate and act on the hose fixed in the cylinder. If one end of the hose falls out of the cylinder, the drive is turned off. In this case, the door will not be able to open or close. Thus, the reasons why the lock does not work or malfunctions can be either electrical or mechanical.

    Repair of partial failures of the vacuum central locking system

    In many cases, central locking malfunctions are accompanied by prolonged pump operation. It does not stop working until the protection turns it off.

    In this case:

    1. The central locking system opens and closes the doors until the compressor turns off. In this situation, the cause is a faulty drive switch. Voltage is supplied to the pump board from the activator; when it is supplied to plus, the doors open or close. The switch needs to be repaired or replaced with a new one.
    2. The doors close and open, the central lock does not open only some of them, while the compressor continues to work until the protection is triggered.

    There may be several reasons for malfunctions:

    • the tightness of the vacuum line hoses is broken;
    • signals are sent to the compressor control board, but it does not respond to them;
    • there is no signal from the limit switch of the drive of one of the doors to the pump control board, so despite the fact that the doors have opened or closed, the compressor continues to work.

    If the hoses are not tight, you should check the entire line. Torn hoses are replaced intact. If the tubes are intact, the drive may be leaking or there may be cracks in the membrane. Faulty parts are replaced with new ones or a new lock assembly is purchased (the author of the video is AvtoMalyarka from Zero).

    In the second case, they check the entire electrical network from the activator to the control board, as well as the voltage on each wire. If an open circuit is found, it must be repaired.

    The reason may be a malfunction of the compressor control unit. In this case, you need to disassemble it and carefully clean the terminal contacts. If this does not give positive results, then you need to check and repair the control board circuit.

    Repair of electric central locking

    Over time, central locking solenoids do not tolerate low temperatures well due to high humidity, especially in spring and autumn. First they begin to jam, and then the door no longer closes or opens. The solenoids can be cleaned and lubricated, but it is better to replace them with motorized drives.

    Activators may not work or work partially on one of several doors for the following reasons:

    1. Damage to the circuit or poor-quality contacts in the electrical wiring.
    2. Relay is faulty.
    3. If control is carried out from the board, then it is possible that the reason is its malfunction.
    4. Poor contact at device terminals or damage to the drive electrical circuit.
    5. Wear of activator components.
    6. The winding has burned out.

    Repairing a car's central locking system should begin by checking the non-working activators to see if they are receiving voltage. If the door lock function is activated, there should be voltage on one wire. If a signal to open is received, voltage leaves the 1st wire and appears on the 2nd. Based on the results obtained, further actions are performed: either the activator is checked and repaired in case of a malfunction, or the entire circuit is checked, correcting damaged areas. Broken wires most often occur in corrugated areas.

    Sorry, there are no surveys available at this time.

    Video “CZ Repair”

    This video tells how to get rid of problems with the central locking of a car (the author of the video is Ksyu and Den. Live blog).

    The comfort of modern cars is impressive, and every year the quality of comfort options improves, and the list is replenished with more and more new features. However, along with additional amenities, car owners quite often get a lot of trouble from an overabundance of electronics and “overly smart” systems.

    Against the backdrop of ultra-modern and newfangled systems, the central lock looks somewhat archaic and primitive, since this assistant appeared quite a long time ago and today its presence will no longer surprise anyone. However, despite the simplicity of its design, which against the backdrop of today’s electronics seems simply medieval, the central lock (CL) quite often fails, which causes a lot of trouble for its owner.

    Over the many years of its existence, the central locking system has seriously evolved, as well as the central locking control system.

    The central locking guards the vehicle's security and protects the vehicle from unauthorized entry into the interior by strangers from the outside. In addition, the central locking system is very convenient, since it allows you to close all the car doors at once, including the trunk, with one movement. Initially, closing was done by turning the key in the keyhole in one of the doors. However, over time, even this seemingly easy and simple movement was replaced by an even simpler one; now, in order to activate the central locking, the driver does not need to insert the key at all, moreover, he does not need to approach the car. Closing and opening of all doors is carried out using a special remote control, which activates and deactivates the central locking using a coded signal. This signal is encrypted and is recognized only by the control unit and the key; communication between the key and the unit is carried out “over the air”.

    More details about the central locking device

    The central lock consists of:

    • Control unit;
    • Input sensors (microswitches);
    • Executive devices.

    The control unit is the brain center that manages signals, sends commands to actuators and analyzes the operation of the system. The unit processes the encrypted signal, after which it decides whether it is possible to close or open the doors and other elements under the control of the central locking system (glass, hatch, trunk, hood, etc.).

    Input sensors or microswitches, as they are also called, work in tandem with limit switches (limit switches) of door locks. After the control unit has “allowed” the door to open or close, microswitches fix the position of the locks.

    Actuators are locking devices, in other words, door locks. The opening of the locks occurs through the activation of microswitches, which in turn received a command from the “brains” of the central locking system. Thus, locks are the last link in this entire chain.

    It should be noted that the central locking is not connected to the engine, unlike the car alarm, which will not allow the engine to start if the lock is not removed. If the central locking system uses a remote control, it is powered by a battery.

    Central locking faults

    The failure of any system can occur suddenly, but often future breakdowns can be prevented by a number of minor failures that are harbingers of serious problems.

    Among these reasons are:

    • Lock malfunctions . When locks are difficult to open or not the first time. Arbitrary closing and opening of locks. Locking of locks, refusal to respond and any commands. In such cases, you often have to break the glass if there are no additional keys or the car does not respond to the key. If you cannot open the door from the inside, you can try to disassemble the door card.
    • Partial failure . Locks and working mechanisms periodically fail and stop working normally. There may be interruptions during signal reception.
    • Complete central locking failure . Complete incapacity of the central locking system, in which the central locking system does not respond to either the button or the key; the unit does not accept or understand commands coming from the key. Often the reason is quite banal - a dead key fob battery, which does not allow sending a signal or leads to it happening incorrectly.

    The central locking does not work - we are looking for the reason!

    Central locking + alarm testing

    Quite often, the central locking system is supplemented with an alarm system, so at the first sign of incorrect operation, you should check the “signaling system”; it is often the cause of all the troubles. If the locks do not work “from the key fob,” try closing them with a key, that is, by placing the key in the keyhole.

    If the central locking does not work only “from the key fob”, while everything is opened with the key, you should check the battery, as well as other control circuits of the alarm.

    The central lock does not close or open, it does not work completely

    If during the test the central locking does not work correctly or is unstable, both manually and remotely, in order to make a “verdict” it is necessary to clarify some nuances. For example, where did the failure occur, are any clicks heard, or do the door lock buttons move when trying to lock the doors. You should check the central locking fuse, as well as other electrical circuits that may be involved in this.

    The fuses are ok, but the central locking does not work

    If the fuses are normal, but you still don’t know why the central locking system does not work, you should continue the diagnostics in order to understand the reason.

    But the problem may actually lie in the locking devices, which could simply fail due to a lack of voltage on the driver's door activators. This happens due to poor contact, oxidation of terminals, and also in case of broken wires. In this case, the driver's door drive cannot send the incoming signal that goes from the remote control to the other doors of the vehicle. This phenomenon occurs in cases where the driver's door actuator limit switch is faulty. The control signal is not detected.

    Repairing the central locking should begin with diagnosing the power supply, as well as the control signal. A visual check of the system wiring is necessary to check for poor connections or breaks. It is also imperative to check the limit switch installed inside the drive.

    Central locking malfunctions: spontaneous locking or unlocking of doors

    It is a common occurrence that after locking the central locking door locks “with a button”, after some time they open spontaneously. That is, the opening occurs even without a signal from the remote control. The reason for this phenomenon may be improper fixation of the rod fasteners, which are located between the drive and the driver's door lock mechanism. Thus, a violation of the opening and closing of doors occurs.

    Possible malfunctions of the vacuum central locking

    During periods of intense precipitation, as well as when the air temperature drops, interruptions in the operation of the central locking pump occur. The reason, as a rule, lies in the appearance of condensation, which occurs when there is a sharp temperature change. There is a malfunction of the contact of the driver's door actuator switch. The solution to this situation is as follows: the switch is dismantled, condensation is removed and the working surfaces are lubricated. In some cases, it is necessary to completely change the mechanism.

    Door locks operate asynchronously, that is, not simultaneously.

    Sometimes on some doors the locking mechanisms do not work the same way or do not work at all, this may happen with some delay or not at all, as a result, the doors continue to remain open, even after the remote control has given the command to lock the doors. In this case, the compressor can continue to operate until the protection system turns it off. In such cases, the tightness of the connections of the vacuum tubes of the line is checked, as well as an inspection of the door line on which a similar phenomenon is observed. The search for damage is carried out by visual signs, as well as by ear, by the characteristic hissing of air being released. If damaged areas are found, repair or complete replacement should be performed.

    The electrical wire in the door corrugation is damaged

    The signals are sent to the pump control board, but it still continues to work, ignoring these commands. Such breakdowns require disassembling the compressor unit with subsequent cleaning of the oxidized terminals of the pneumatic sensor of the alarm system. If after the measures taken the situation has not changed, it can be assumed that the pump control board has failed.

    Car central locking repair

    From the above, we can conclude that electric central locking systems are very sensitive to temperature changes and wet weather, as well as to interruptions in the vehicle’s electrical circuit. At first, this manifests itself in “braking”, untimely operation, as well as periodic failures. Daily use of the central lock one way or another leads to wear of the working parts and gears, as well as the drive itself. Plastic mechanisms wear out due to stress, as well as lack of proper lubrication. Preventive maintenance of the central locking system allows you to prevent serious breakdowns, as well as extend the service life of the entire system as a whole. In addition, a working central locking and alarm system eliminate the possibility of unpleasant situations when you find yourself alone in the middle of a deserted highway with your unauthorized lock.

    That's all for me, thank you for your attention, I look forward to your comments on this issue. Ask your questions, I will try to answer them. I also recommend that you subscribe to new, no less interesting publications on our website. I would be grateful if you share this article on social networks using the appropriate buttons located below. Bye!

    The central locking VAZ 2114 (hereinafter referred to as CZ) is a mechanism that ensures the simultaneous closing or opening of all four doors in the car. This option is very convenient; it eliminates the need to reach out and lock the doors manually every time. Such centralized control comes in handy when installing car alarm systems, which significantly expands the possibilities and variations of the use of the locking mechanism.

    The operation of the lock itself does not depend on whether the car engine is running or the fact that the ignition is turned on. Power is supplied directly from the battery.
    It is quite common for the system to malfunction. For example, when the locks of some doors close, but the rest do not. Or the closing process occurs with great difficulty, jamming, or partial failure of the latches. A situation familiar to many car enthusiasts, isn’t it? There are several reasons for the node to not work correctly; we will look at them in more detail.

    7 common faults

    Why does the central locking of the VAZ 2114 not work, you ask?
    Most often, interruptions occur due to temperature changes and humid weather. The first signs are unclear operation of the lock, jamming or incomplete operation.

    Below we list the top major breakdowns:


    Central locking diagram for VAZ 2114

    The system consists of the following components:

    • mounting block;
    • 8 amp fuse;
    • 4 gearmotors (one in each door, and the one in the driver's door has a contact group);
    • central locking control unit;
    • wires (red, black, blue, yellow) and plugs;
    • rods that are located in each door;
    • limit switches that signal the current state of the door (open or closed).

    Where is the central locking of the VAZ 2114

    The central locking system is located in the driver's door, just like the electric drive. If we talk about the system as a whole, it is distributed over 4 doors (in some cases it also extends to the trunk), and the central panel (control unit).

    Testing and diagnostics

    If your car is equipped with one of the alarm systems, then it is better to start diagnostic activities with it.
    You should check the operation of the central locking when using the key fob, and when opening and locking with a key. If, during a manual check, the central locking system works correctly, then the reason is the alarm.
    Additionally, it would be a good idea to check the battery charge level, since if it is insufficient, interruptions in the operation of many electrical consumers occur.
    In general, it is best to check, as they say, along the path of least resistance. That is, diagnose something that does not require significant effort. And if the fault cannot be identified, resort to disassembling the driver's door and examining the mechanisms along with the electronics.

    conclusions

    In this article, we touched upon only some of the most common problems associated with the operation, repair and maintenance of a centralized lock. Despite the fact that the node has plenty of problems, restoring its functionality is not a difficult, much less an impossible task. Usually, to achieve smooth, efficient operation of the system, only practical skills are missing. After receiving them, you will be able to repair any complexity! If you want to install the central locking on a VAZ 2114 yourself, then here is a video instruction:
