Central locking is a useful and convenient option in any car, so failure of this system often becomes a serious nuisance. Most 2114s came with a central locking option from the factory. Over time, the system begins to work incorrectly, which manifests itself in rare activation of door locks or complete failure. One of the reasons for the failure of the central locking system is a burnt-out fuse for the central locking of the VAZ 2114. In the article, we will look at the main locations of the fuse, and also analyze other reasons for the malfunction of the central locking system in the “four”.

Signs of trouble
Why does the VAZ 2114 heater fan not work
? The occurrence of any malfunction in the operation of the central car lock instantly manifests itself in the form of a violation of its functionality. In this case, the signs or symptoms of a breakdown correspond to what exactly happened to the system. Therefore, problems can be identified by the following nuances:
- it is not possible to open the car using the key fob;
- opening does not work when using the key;
- the key fob does not lock the car;
- the key or button does not work when closing the door;
- one of the doors does not open or does not open;
- The central locking is triggered, closes everything, but immediately opens without a corresponding command from the driver;
- locking and unlocking work spontaneously.
We can say that malfunctions manifest themselves in the form of incorrect operation of the system. The central locking system is a complex device that consists of a large number of components and control units. This is a whole network of electrical wires, which sometimes covers the entire car. Given the complexity of the system, consideration should be given to who will carry out the repairs. It is often recommended to entrust this to specialists. At the same time, every motorist has the right and opportunity to know what malfunctions occur with the central locking, what is their cause and how they can be dealt with. Whether to repair it yourself or trust the experts is a purely individual question.
Let's sum it up
As you can see, if the lock on the doors of a car does not work, there can be many reasons. However, taking into account the above information, it becomes clear that knowledge of the general structure and operating principle of vacuum and electric central locks allows you to quickly localize the problem for accurate diagnosis and high-quality elimination of potential faults. It is important to consider what type of locking system is on the car, and also to know the typical breakdown of locks of one or another type.
We also recommend reading the article on how to connect USB to an old radio. From this article you will learn about available ways to upgrade old head units to be able to listen to music from a flash drive, via AUX, etc.
Finally, we note that when installing a central lock in a car, it is advisable to take into account all the installation features, as well as responsibly approach the selection of all system components. The fact is that today there are a large number of similar solutions on the market, but not all central locks are distinguished by quality and durability.
This means that it is important to purchase a device that has reliable components and install it correctly. Only this approach will allow you to obtain long and trouble-free operation of the central locking system.
Other problems with central locking and self-check of the system
VAZ 2110 reverse light does not work
In the case where the lock was installed at the factory, for the time being it worked flawlessly, but suddenly a failure occurred, you will have to check the entire system. You can do this yourself, for which you will have to check almost all possible options - from fuses to the performance of final actuators.
Checking fuses
In case of any problems, the check should begin with the fuse box - often one of them becomes the culprit. If a fuse on one circuit systematically blows, it must be checked especially carefully, especially the condition of the activator - perhaps it is this that causes the short circuit. How to find fuses can be seen in the video:
Checking the electrical wiring
Attention! When the central locking does not work, checking the wiring is, although time-consuming, but necessary.
It should start from the entrance points to the doors, because it is in these places that the wires often break off or short out due to wear and tear of the insulation. The supply of electricity should also be checked. To do this, the wires are disconnected from the activator, and the “closed” mode is activated by the remote control. Voltage should appear on the supply wire. When you press the button that opens the lock, power should flow to another wire. Each activator is checked in this way.
Checking actuators
When the central lock does not open one door or there are periodic failures to operate, the activator itself may be the cause. If it operates on the basis of an electric motor, under certain conditions its winding may burn out or the gear that ensures the translational movement of the rod may wear out. Repairing this part is impractical; it is easier and faster to install a new activator.
Advice! There is also a situation where the central locking does not work after removing the battery. It is worth understanding that this system does not work without a battery, and it is highly undesirable to de-energize it. This may lead to a malfunction of the control unit and the need for its subsequent repair or replacement.

Where is the central locking fuse on a VAZ 2114?
Auto-help Why the fuel pump on a VAZ 2110 does not work
Central locking, or “CZ” as it is briefly called, is a necessary and essential thing for any car, allowing the owner to open and close any door in the car with just one movement of the hand. However, it happens that this system ceases to function completely, or its individual parts do not work properly.
There are reasons why one or another part of the central lock may fail, and we will discuss each in detail below.
The central locking does not work: signs of malfunction and causes of their occurrence
It happens that when the central lock located on the driver's door is closed, no action occurs on the other doors. However, as soon as you move it a little, the doors immediately closed. It is immediately clear that the problem here is the presence of malfunctions in the central locking and several reasons contribute to this.
Among all the possible causes of malfunctions, all the most basic ones can be identified.
No contact in the drive
With such a malfunction, the contacts inside the control drive do not close the necessary contacts in time. This happens for several reasons:
When such problems occur in the operation of the central locking, first of all you need to make sure that the button is lowered to the very end. If for some reason this does not happen, first inspect the casing for burrs, and then inspect the rod for its even and accurate position.
Fuse blown
If manipulations with the central locking rod do not bring any results, and they do not react in any way to either opening or locking, then first of all you need to check its electrical circuit, and specifically the fuse. Because on the central lock it can fail not only if a short circuit occurs in the circuit, but also if the slightest overload occurs.
The central locking fuse is indicated by a marker.
Overload occurs most often from insufficient position of the rods, as well as lubrication in them during winter operation of the car.
The central locking wires are broken
Broken wires are not the main reason, but one of the reasons for the failure of the central locking system. The main reason for this is the break in the wires in those places where they bear the greatest load. Such a place is definitely the passage of the corrugation from the side of the pillar and the driver's door. And since it is the driver’s door that is most often opened in any car, it receives most of the load.
- It is quite easy to identify such a malfunction; you just need to release one of the ends of the corrugation through which the wires pass into the door and pull one of the five central locking wires. As a rule, they are connected into one bundle, or go next to each other.
- After carrying out such manipulations, a wire that is torn or broken will easily give in among the general heap.
- If you are absolutely sure that a particular circuit is faulty, replacing it will not be difficult by inserting the required wire and further insulating it with electrical tape.
- When the wires are broken or torn in other places, the fault can only be found by testing the circuit with a multimeter.
Block burned out
Another reason why the central lock may fail is a burnout of the central locking unit. And in order to diagnose it, you need to use the above-mentioned multimeter and determine the presence of voltage at the contacts of the block.
This is what the immobilizer and central locking unit look like behind the instrument panel.
Please note that during diagnostics it is necessary to operate the lock in the driver's door so that impulses are sent from it to the main unit
The central locking activator is faulty
And the last reason why the central locking refuses to work is the failure of the activator on the central drive. It can fail both for mechanical reasons, due to wear of rubbing parts, and due to the influence of external factors of moisture and corrosion.
If the activator itself breaks down, it is necessary to replace the electric drive with a new one and replace it
Please note that the drive must have five wires of different colors
The principle of operation of the central lock on the VAZ-2112
The central lock, which operates from the driver's door drive of the VAZ-2112, works as follows:
When the lock closes, the rod on the driver's door moves down, thereby closing certain contacts on the electric drive. From these actions, the central locking unit receives signals and transmits commands to the drives of all other door locks. Their discovery occurs in the same way.

Further:
Common node faults
Often the central locking of the VAZ-2114 is controlled incorrectly due to the fact that the contact pairs are closed with a delay. A common reason for this is a violation of the adjustment of the thrust located between the gearmotor and the lock button, or its jamming. Simply put, when the button is pressed, the position of the rod does not allow the contact pairs of the drive to be completely closed.
The door on the driver's side may be locked, while the others will remain open due to the fact that the contacts of the control unit are not fully closed. This malfunction is purely mechanical in nature, and to eliminate it, it is enough to adjust the rod or the free play of the button in case it gets stuck.
In addition, such a problem can be caused by a malfunction of the VAZ-2114 central locking relay. In this case, you will have to replace the failed element.
In the case when the VAZ-2114 central locking completely stops responding to commands given by the driver, it is worth moving on to checking the electrical part of this unit. It is possible that this behavior of the system is caused by a blown fuse. Note that it can fail not only in the event of a short circuit, but also from constant overloads caused by the heavy movement of the core, or a violation of the adjustment of the rods.
Quite often, the reason why the VAZ-2114 central lock does not work is a violation of the integrity of the electrical wiring supplying power to it. The wires in the driver's door of a vehicle almost always break because it opens and closes more often than others. You can determine the damaged section of the wire using a multimeter. Less often than not, the control unit fails. In this case, the entire system either completely stops working or performs its functions incorrectly.
To prevent module malfunctions, it is necessary to pay attention to the condition of the activator, since its contacts can oxidize or burn, causing malfunctions. Periodic cleaning will significantly extend the life of the module.
In a modern car, central locking (CL) has become a convenient addition, which allows the driver to open all doors at the same time. The article discusses the central locking VAZ 2114: operating principle, typical faults, installation instructions.
Principle of operation
The central car lock consists of:
- central electronic unit;
- electronic units for front and rear doors (not always present);
- driver's door electronic unit;
- push-button switches for all doors;
- limit switches for closing windows and doors;
- control units and window lift drives.
In most cases, the units responsible for controlling the power windows are directly connected to the central locking and combined into a single system. When the doors are closed, the central locking checks the condition of all doors and windows so that they are not left open when closing and activating the alarm. The central locking system cannot be considered a separate element of the car. This is the name of all system components responsible for locking the locks in the vehicle. The task is to simultaneously open and close doors, raise and lower windows, and sometimes also be responsible for opening the fuel tank lid.
The principle of operation is based on the fact that when you turn the key in the driver's side door lock, a microswitch is activated, which is responsible for the locking process. From it a signal goes to the door control unit, and then to the central unit. From there, control signals are distributed to each of the available control blocks. This allows you to simultaneously close all doors, windows, etc. When you turn the key again, the reverse process occurs, that is, unlocking. Depending on the type of device, the central locking system can be triggered by contact or non-contact methods. The second option involves using a special button on the car keys.
Possible malfunctions of the locking system
If there is no reaction when you turn the key in the lock or press a key on the remote control, this means that the central locking is not working.
All causes of central locking malfunction can be divided into two types:
- technical;
- related to climatic phenomena.
In the first case, breakdowns are possible due to incorrect installation or configuration of the locking system. Subject to natural wear and tear after long-term use. The service life directly depends on the quality of the device.
In the second case, the central locking system may fail under the influence of low temperatures and it may freeze. The lock may not work if water gets into the mechanism during rain or melting snow.
The central locking system may not work due to an incorrectly installed or faulty alarm system. In this case, you should diagnose the locking system. The control activator is installed in the driver's door. As soon as the drive is activated, signals are sent through the appropriate channels to the remaining activators, according to which the required action is performed. Therefore, you should check the operation of the lock using the key and the button on the key fob.
If the doors sometimes close, sometimes they don’t, then the reason may be in the control circuit or a violation of the integrity of the electrical circuit of the car alarm. The reason why the central locking system fails to operate may be insufficient battery charge or a blown fuse. Depending on the circuit being used, there may be multiple fuses. They all need to be checked and faulty ones replaced.
The fuse can burn out as soon as it is installed, due to a short circuit or overload, for example, when controlling the central locking with a key fob, and not manually. In warm weather, the reason is a short circuit, which is possible due to poor contacts or an open circuit. The cause of the breakdown may be a malfunction of the central locking control unit.
You can check the operation of the unit using a multimeter by checking the power supply to the activators. Current is supplied to the contacts of the unit by unlocking and locking the driver's door. If the control unit is broken, it needs to be replaced.
Where is the VAZ 2114 central locking relay located?
Dear visitors of the site “All about cars”! We will be very grateful for your comments on the video clip “Where is the VAZ 2114 central locking relay located?” registration is not required for this. We also ask you to let us know if you have any problems playing the video.
Video 5+. The question arose: is it possible to make the LEDs light up one by one? Similar in type to the new Audi taillights.
Thanks for the video I'm having problems with the alarm in my car.
Very helpful. Basics of circuit design. Showed it to my son. He finally understood the principles of the relay. By the way, RELAYS were shouted on the crossroads at one time. That is, take it and pass it on. If I'm not mistaken, the French word
minus 12V - does this mean 0V? or is it from a 24 V diesel engine?
Why a diode?
Author please make a project on how to attach a battery from a laptop to a smartphone battery, how to increase its capacity, if this is possible of course
Excellent video, I finally understood the algorithm of the relay. Are you planning to make a video on installing the alarm? It would be interesting
Thank you for the detailed story, if there is no signaling at all, is it possible to use a radio key fob, for example from a gate or barrier, to control the gearmotor, if possible, write a diagram, thank you
Tell me, what if the gearmotor with 5 contacts is white, black, brown, blue and green. Which ones should I use? I'm guessing green and blue?
THX. everything is clear and clear to the author, only I connected the ESP to the Lanos according to your diagram, for some reason it only works for the ascent, it doesn’t work for the descent, maybe I should give + to the buttons to? 5-pin relays without a diode, post a video of connecting the ESP via a relay, if available, thank you.
Brother, call me on WhatsApp +77085506656 I have a VAZ 12, I can’t figure out whether it opens or not, I bought new locks, well, it can’t be like that, you noticed correctly, I can’t seem to get the hang of it
I have a problem, I have a Starline 91a, and my car is a Hyundai Elantra, the center lock is controlled via minus, I connect the relay, but the lock does not respond.
Hello, please tell me, I connected the center lock den, it worked and now it doesn’t work, why should I thank you for the answer.
Installation instructions for central locking
Before installing the central locking system, you should study the connection diagram
Photo gallery “Central locking diagrams”
The central locking control module is located on the left side under the panel. There are 6 wires coming from it. To install the central locking system, you need to disconnect the brown and blue wires.
Before connecting, you need to check that activators with 5 outputs are installed in the doors. If they are missing, they should be installed.
In a VAZ 2114 car, the wire responsible for opening the doors is usually white and connected to terminal 7. If there is no connection to terminals 7 - 5, then the 8th terminal is connected to the brown wire. This wire is responsible for opening the doors. Terminals 5 and 6 are for closing doors.
To install the central locking system, you must purchase additional items:
- 2-3 diodes 1N4001 at 1A;
- one diode 1N5401 3 A;
- 2 diodes of 4 or 5 A, if there are no separate outputs for turn signals.
After connecting the central locking system to the alarm, you need to check its functionality.

Repair features
If the central locking of the VAZ 2114 has stopped working, then you need to conduct diagnostics and find the cause of the breakdown (the author of the video is Nikolay Bogdanov).
Then carry out the appropriate repairs. Problems with central locking on the VAZ 2114 most often arise at low temperatures and high humidity. The reason is the locks with solenoids that are installed from the factory. It is better to replace them with locks with an electric motor.
If the drive is not working on only one door, it is necessary to check its electrical circuit for an open circuit by testing it. Most often, broken wires are located in the corrugation. Since the doors are opened and closed frequently, the insulation cannot withstand the load. The break is restored by replacing the wire and connecting the broken sections using female-male terminals.
Diagnosis and care
In order for everything to work normally and without failures, this system must be promptly maintained and diagnosed. In fact, the car must be constantly monitored by the driver, otherwise some systems may fail while driving.
The main failure in the system is that after washing in winter, the locks freeze. In order to avoid this problem, you should ventilate the lock. Unfortunately, many car washes do this rarely or not at all. When the lock freezes, the driver simply will not be able to get into the car because the cylinders freeze and the key cannot be inserted or does not open the door.
It often happens that after washing the driver easily opened the car and drove home or to work, leaving the car on the street for some time, the moisture in the lock freezes, does not allow the larvae to move, and when the driver tries to open the door, the key simply cannot be inserted into the larva of the castle.
Freezing of larvae happens not only with central locking, but also on cars that do not have this system. On those cars where there is no central locking, everything is much simpler; all you have to do is pour hot water on the lock, the cylinders will begin to move and the car will open. The situation with the central locking is more complicated; here the rods freeze, blocking all the doors.
Pulse programming
When connecting a central lock, it is not enough to perform all the steps in the correct sequence; you also need to select the required pulse duration for the locks to operate. If it is too large, the actuators will overheat; if it is insufficient, it will not be enough to open and close. In the luxury configuration, all electronics usually “fall asleep” after 15 minutes of inactivity. To awaken it, an additional impulse is needed.
Central locking is a simple device, but it can secure your car from criminals much more effectively than a police cap on the passenger seat. The centralized door lock system is the most convenient way to quickly open and close them. If this security system is supplemented with a good car alarm, this will prevent you from ending up in a situation where your car is stolen or damaged.

Replacing the ignition switch on VAZ 2114 and 2115. Work in the evening
- A set of keys. It should include both regular keys and heads;
- Phillips and slotted screwdrivers;
- Pliers;
- Thin chisel;
- Hammer.
- You should start by removing the steering wheel. To do this, use a slotted screwdriver to pry up and remove the trim with the Lada inscription (in some cases Lada). This will give you access to the 4 screws securing the steering wheel cover. Unscrew all the screws and remove the cover;
- Lightly unscrew the nut securing the steering wheel. Don’t unscrew it completely right away;
- We tear the steering wheel off the splines. At the same time, you need to apply quite a lot of force to it. To avoid damage, leave a nut that is not completely unscrewed as a limiter;
- Next, you should completely unscrew the nut and remove the steering wheel from the car;
- Remove the plastic casing from the steering column using a Phillips screwdriver;
- The block and wires are disconnected from the ignition switch;
- Turn the key to position I, this will remove the lock from the groove, and you will not have any problems when removing the unit;
- To remove the ignition switch, you need to unscrew the bolts that secure it. This is where a little difficulty arises. For greater reliability and security, the bolt heads break off when installing the lock. To unscrew them, you need to use a thin chisel. It is placed on the head of the bolt and, applying light blows with a hammer, we unscrew the fastener. As soon as you manage to unscrew the bolt a little, finish the job using pliers. They do the same with the rest;
- The old castle is being removed. If desired, it can be restored;
- Reinstall the new or repaired lock. At the same time, be sure to make sure that the tongue blocking the steering wheel is in the correct position. Before installation, it should be recessed into the groove of the lock;
- Tighten the screws securing the lock. Their heads are designed like a kind of torque wrenches. As soon as the tightening reaches the required torque, the head simply breaks off. Thus, the bolts are disposable. They are usually sold together with a lock or in separate repair kits;
- A block with wires is connected to the contact group;
- All removed parts are reinstalled.

Replacing the battery in the key fob
A sign of a low key fob battery will be the LED flashing quickly when you press any button. The central locking does not respond to commands. It is worth noting that a discharged battery will not affect the ability to start the engine. Since the immobilizer can easily read the code written on the chip, synchronization will not be lost.
Disassembling the key fob is very simple; just unscrew one screw on the body and, using any available tool, remove the cover on which the buttons are located. Next, the printed circuit board is removed, under which the battery is located. You need to determine its type by reading the letter and number combination. When replacing, be sure to take into account those same 6 seconds, i.e. have time to install a new battery during this time, otherwise it will be necessary to restore synchronization.
Device
The central locking system consists of several main devices that must be operational in order for the system to work correctly according to its principle.
- The main thing in this system is the control unit. It is the control unit that supplies all the signals to the actuators that perform the assigned tasks.
- The actuators, as already mentioned, perform the tasks that the control unit assigns to them.
- The third important component of the system is the sensor system. Sensors send signals to the control unit, and the control unit sends signals to the actuators.
When the driver gets into the car and turns on the power (ignition), the car will automatically lock. This is necessary to prevent the doors from opening while moving. There are systems where the car will not be able to move while they are open. During an accident, the central locking system recognizes that a collision has occurred and automatically opens the doors.
General information
To begin with, it will be useful to find out where the immo is located, because if this device does not work, to disable it you need to gain physical access to the device. In VAZ 2115 cars, the immo is located behind the center console, to the right of the steering wheel.
Today there are two types of devices: contact and non-contact. Contact systems are controlled using keys, while contactless systems are controlled using special chips built into a key fob or card. In the case of VAZ cars, immos are installed only on injection versions of cars.
Principle of operation
The operating principle of this device is based on data exchange between the control unit and the immo. The anti-theft device transmits data to allow or prohibit the start of the power unit. If prohibited, the system automatically blocks the ignition circuit with the fuel pump, and accordingly, starting the engine will be impossible. That is, without initialization the power unit will not be able to start.
