Door lock device VAZ 2107

Often, owners of VAZ products have to remind their passengers that the door can only be closed if they slam it quite hard. And, unfortunately, both the front door and the back door close this way. It is difficult to imagine a VAZ-2107 car owner, or any other model, who would not want to correct such a defect. In this article we will show you how to find a way out of such a predicament, using silent car locks that are installed on more modern models, for example, on the VAZ-2114 or VAZ-2115. And since installing silent locks on a VAZ-2107 does not require special skills, every car owner can easily cope with this task if he performs the work step by step.

We adjust the VAZ 2107 door lock with our own hands

The doors in any car should always be in good condition. This is necessary from the point of view of not only comfort, but also safety. The serviceability of the devices means the normal functioning of the windows, locks, latches and handles. All these mechanisms must work flawlessly when used, regardless of the weather outside.

VAZ cars are especially in need of care and maintenance, since their build quality usually leaves much to be desired. In this article we will find out what adjusting the VAZ 2107 door locks is, how it is done and the main problems that may arise with door mechanisms on a car.

When might it be necessary to adjust the doors of a VAZ 2107? This happens in cases where the locking mechanism refuses to function. The inoperability of the locking mechanism is manifested by jamming of the doors, while they cannot be either closed or opened.

It is important to know! Reviews from owners of "Sevens" show that the most common disease of VAZs is door misalignment (sagging). When skewed, they close very poorly and are difficult to open, so it is urgent to take appropriate action to eliminate the malfunction.

There are also cases when faulty locks allow doors to open while the car is moving. Over time, any parts wear out, and with frequent and careless use, the locks can fail at any moment. To correct the situation, it is necessary to periodically diagnose the door locks on the “seven”.

Conclusions, purchasing a central locking system with remote control and other useful information

In order to install a central lock that will close all doors when turning the key, you should purchase a separate central locking unit (small “black box”), as well as a special master activator (5 pins) for the driver’s door, or also for the front passenger door (where there is a lock cylinder and the ability to open the door with a key).

In this case, there is no need to install an alarm, and the process of installing and connecting the actuators is similar to the example above. The only differences are that you will have to lay additional wires for the driver’s door electric lock, and also “figure out” the connection diagram for the central locking control unit.

Central locking with remote control for 4 doors

You can also buy a separate central locking kit with remote control. This set already includes a central locking control unit, 4 activators, wires, fasteners and 2 key fobs. A universal kit will cost about 1000 rubles.

Where can I buy? You will not find such a kit in retail stores at the price mentioned above. To do this, use sites that sell electronics and other devices directly from China. Try not to deal with intermediaries, but order directly.

We recommend Aliexpress.com, but be careful with sellers and look at customer reviews. As an example, Universal Car Central Locking System.

Working principle of the door lock

The VAZ 2107 door lock has internal teeth; turning the key sets them in motion. When closing, the pins move in such a way that they fall into the grooves and the device is locked. If jamming occurs or difficulty opening/closing the blade occurs, it means that the pins have not completed their path completely.

If the driver hears a creaking sound when turning the key or jamming, then disassembling the device is required. If the key does not fully enter the keyhole or if the mechanism is damaged, replacement of the cylinder or the entire mechanism is indicated. Wear of internal elements is the most common reason for repairs. To carry out this procedure, you need to purchase a new cylinder or lock, prepare a set of tools and lubricant. After disassembling the device and visually, installing a new element is not always required. Sometimes it is enough to lubricate the pins with silicone.

Structure and purpose of the ignition switch

The ignition switch (lock) on all “classic” models, including the “six”, is absolutely similar in its structure and design. Let's consider its structure and principle of operation.

Ignition switch (lock) device:

Locking rod
Frame
Roller
Contact disc
Contact sleeve
Block
Protrusion of the contact part.

The lock mechanism is connected to many wires. They continue from the battery, connecting all the electrical devices of the car into a single chain. When you turn the ignition key, the electrical circuit is closed from the “-” terminal of the battery to the ignition coil.

As a result, the current passes through the wires to the ignition switch, through its contacts it is directed to the induction coil, after which it returns back to the “+” terminal. As electricity passes through the coil, it generates high voltage, which it transmits to the spark plug. Therefore, the key closes the contacts of the ignition circuit, thereby starting the car engine.

The ignition switch, like all spare parts, requires repair or replacement over time. And any car enthusiast will be able to cope with this, having a minimum amount of necessary knowledge.

External handles and solving problems with them

Adjusting the VAZ 2107 door locks may be necessary in several cases. The most common is a failure of the locking mechanism. The doors may jam or, conversely, the lock may not close. Door misalignment is also common. Even in the new sevens, this happened quite often, and already seen examples suffer from skewed doors without exception. Another thing is that the owners do not notice this for the time being.

A skewed door is dangerous because the lock at a certain moment may simply not work or unlock on a bad road. It will also not be news that tired 7 bodies can live their own lives and slowly lose rigidity, which affects the loss of doorway geometry. Since the door is more rigid, it is not going to adapt to the new geometry of the body and the only thing that can save the situation is adjusting the lock if the geometric changes in the opening have not yet reached critical values. But fortunately, this happens extremely rarely and to very inattentive owners.

You can often see problems with external handles. The design of the handle itself is quite decent, and if it is periodically lubricated with silicone grease, it will work for a long time without wedges or jamming. The rod from the handle to the lock may become loose, and in this case the rod simply bends until the handle begins to fully open the lock.

By devoting half a day to the procedure for adjusting the door locks of the VAZ 2107, you can forget about door slams and impacts for a long time, the mechanism will work clearly and quietly, the main thing is not to forget to lubricate the mechanisms and rods from time to time. Good luck with all the adjustments and happy travels!

Regardless of the make of the car, the door is an integral part, but the correct operation of the door mechanisms is no less important. Over time, the door and lock need to be adjusted due to the formation of wear. Otherwise, locking becomes problematic and sometimes even impossible.

Door handles (external and internal) of the VAZ 2107 are designed to unlock the door. Over time, these parts may fail, which means they need to be replaced.

External door handles of the VAZ 2107 are left and right, which must be taken into account when purchasing and replacing. In addition, the part can be made of metal or plastic. A metal handle, although more expensive, is much more reliable, which is especially important in winter: you can apply pressure without fear of breaking it if it suddenly freezes.

General practical information about the structure of the larva

In cylindrical designs of the locking mechanism, the cylinder most often fails. The part cannot be repaired; the cylinders are replaced only in pairs, simultaneously for the left and right doors. For the work you will need a flat narrow screwdriver and metal wire. Scheme for replacing the VAZ 2106 door lock cylinder:

With the lock removed, remove the spring that releases the key in the cylinder by prying it with a screwdriver.
Use a thin wire to press out the fixing rod.
Remove the top ring, the cylinder is removed from the back of the lock.
Replace the part and configure it.

In addition to replacing the cylinders on the front doors, it is recommended to change the locking elements on all elements and in the trunk lock so that it can be opened with one key.

Door lock repair

To repair the larva, you will need to reassemble individual parts and lubricate. To perform this you will need a set of screwdrivers, pliers and lubricants. Basic recommendations for setting up the internal mechanism:

spring replacement;
pin adjustment;
sharpening of teeth;
replacing the lining or tongue;
lubrication, performance check.

Adjusting the gap and hinges

Adjusting door locks is within the capabilities of anyone who is able to hold a socket and open-end wrench in their hands, although this procedure requires some time. To begin with, they diagnose the operation of the lock mechanism and inspect the condition of the gaps between body panels, front fenders, pillars and door frames.

Unfortunately, those three millimeters of gap, which should be evenly distributed along the entire perimeter of the door, on the VAZ 2107 exist only in the drawings at the design bureau in Togliatti. In fact, the gap can be from three to seven or more millimeters. Regardless of its size, the main thing is uniformity.

This will make the task even more difficult, but there is no other way out. In some cases it is necessary to adjust the loops in pairs, and in some only one, it all depends on the direction of the skew. When adjusting the gap, you should pay attention to the condition of the seals, since they, as a rule, can greatly influence the location of the door in the opening.

Installation of anti-theft system and components

Installing an anti-theft system takes a lot of time, but it's worth it. The anti-theft system for VAZ 2107, 2106, 2105 is installed under the front panel or under the sound insulation of the engine compartment. In the first case, the front panel must be removed, but despite this, this method is considered more deliberate, since the alarm units are located more reliably.

First of all, you can install the LED by fixing it on the front panel near the windshield. If you are installing an alarm system on a VAZ 2107, 2106, 2105, the block can be located on the left, right or center, respectively. Using a tester, find the wiring of the central locking, door opening buttons, and ignition. If there is no central locking, it is necessary to install an electric drive under the door trim, which is connected to the main alarm unit.

You can install an electric drive on all doors using turn signals and wires with limit switches. We mount the siren under the hood so that it is invisible and difficult to access. It must be secured with a screwdriver so that dirt, water and dust do not get into the horn. To avoid breakdowns, all parts of the car alarm should be well secured and the connections should be insulated. To reduce the likelihood of your car being stolen, you need to block the engine, fuel pump, starter and ignition.

How to remove a door lock

The lock is removed not only to replace it, but also in case of internal faults. If the grooves are displaced, then the right side is pryed off and the pins snap into place. To do this, you will have to analyze it according to the diagram and prepare the tools. To remove you will need: screwdrivers and a knife. Instructions:

On the device, unscrew the three bolts on the handle with a Phillips screwdriver.
The cover, plug and facing material are removed.
Electrical wiring is disconnected.
The inner panel is removed to get to the outer element.
The pull is removed and disconnected from the handle. To do this, you will need an impact screwdriver and a 8-mm wrench. The return spring is dismantled. The old larva is being removed.

The core of the closing structure can be replaced if the failure is related to the operation of the internal teeth or grooves. To check this, remove the tip from the cylinder.

How to open the trunk

remove the back of the rear seat and the plywood wall located behind it;
remove the two 10mm nuts that secure the luggage compartment lock;
get out of the car or have an assistant press the lock from the outside;
open the luggage compartment.

The most difficult thing in the described method is to unscrew the nuts from a distance. Therefore, some car enthusiasts give different advice. For example, punching a little above the license plate will help open the trunk. If you are dexterous enough, you can try to pick the lock with a metal pin, wire, a narrow ruler or a sharp nail file. Another way is to use an awl to bend the lock tab. To do this, you will need to bend the seal that runs along the perimeter of the trunk lid.

If you are going to change the lock on the luggage compartment anyway, you can use a radical method. Just drive a screwdriver into the lock and turn until it clicks. To do this, it is best for you to take pliers.

Algorithm for adjusting lock 2107

It is hardly possible to systematize all possible problems with locks on the seven, but to eliminate malfunctions, first of all, they carry out a thorough inspection of the mechanism, lubricating the bolts, checking the rods and hinges. The procedure for solving incorrect lock operation looks something like this:

without removing the clamp on the body pillar, outline its outline;
if the door closes too tightly or only with one click, unscrew the latch and move it the required distance outside the body;
in cases where the door slams two clicks, but the gap remains, the planes of the door and the wing do not coincide, the latch is weakened and shifted inside the body;
When the door is closed and the locking mechanism is activated, the door must remain vertically stable, that is, in the case when the door rises when closing, the latch is lowered, otherwise, the opposite is done.

There are often cases when the lock does not work well when unlocked from the inside, although it opens satisfactorily from the outside.

This problem is solved by adjusting the position of the door opening handle - the fastening screws are loosened and the handle is set to the optimal position, after which the screws are tightened.

Refinement of VAZ classic locks + video report

The idea came to mind to tinker with the door locks. Somehow they didn’t close very well.

Having looked at the design of the locks, I realized that the design is very simple and there is really nothing to modify in it, except for one spring. The fact is that the respected and beloved AvtoVAZ decided to make these locks reliable, so the spring acts as an insurance policy in case the springs on the door handles fail or jam. If the return springs in these elements jam or fail, the lock spring will save the situation and the lock will not jam in the open position (in the closed position, due to design features, it has extremely little chance of jamming).

Replacing the larva

Once the core is removed from the metal box, it is important to ensure that there is no contamination or deformation inside. If this is the case, then the lock will have to be replaced completely. A new core is inserted, and then reassembled:

The spring is put in place.
Traction is connected. The nuts are tightened with a wrench.
Electronics are being connected: power windows, side view mirror.
The door card is returned to its place and secured with clips.
The handle is screwed on and the plug is installed.

Preparing for installation

Installing silent locks with your own hands is not that difficult. The most important thing is to perform operations in a certain sequence. First of all, you need to provide access to carry out this operation. To do this you will have to dismantle some elements.

The first step is to unscrew the inner door armrest. It is attached with three bolts, under a cross bit.
Then the window lifter handle unlatches. To do this, immediately use a flat screwdriver or a metal hook to remove the fixing ring, and then pull the part towards you.
The next step is to remove the decorative rim from the inner handle of the lock.
After this, you can remove the door card. It is held on by plastic clips; very often they break during this operation. When installing the panel back, you need to replace the damaged latches with new ones.

Having completed the above points, the preparatory stage can be considered complete. Next, you need to remove the old locks.

Refinement of the base and mechanisms

It is not enough to replace the larva; you need to make sure that the core is working. To do this, you should set up the mechanism before the door structure is assembled. Recommendations:

A key is inserted to check the operation of the larva. The lock opens and closes several times. If movement is difficult, the pins may need to be lubricated or adjusted.
Special spacers are fixed, which prevent the teeth from deforming or moving to the side.
Sometimes it is necessary to change the spring, which hinders the operation of the system.

To adjust the new pattern, the front of the lock is stripped or ground. This work will allow you to repair the damaged mechanism if there was an attempt to break into it. You should first make sure that the master key has not damaged the insides.

Self-replacement of the ignition switch of a VAZ 2108

For this work, you need to use special bolts with break-away heads; I do not recommend using twenty-millimeter M6 bolts instead, since in this case it will be easier not only for you, but also for car thieves to remove your ignition switch.
Using a chisel, you need to unscrew or knock down the bolts.

Before replacing the lock, turn the key to the “I” position so that the latch that locks the steering shaft mechanism can enter the lock body.
Now that nothing is in the way, you can begin installing the new ignition switch.
Install it on the steering column, secure it with a bracket, then tighten the structure with new mounting bolts.
After installation, do not forget to make sure that the steering shaft locking mechanism is working correctly; if the mechanism does not work, after a full turn of the steering wheel, you need to adjust the position of the ignition switch on the steering column.
Upon completion of adjusting the position and checking the functionality of the locking mechanism, tighten the bolts until the heads are completely torn off, to do this, use a “10” spanner.

Start the engine, make sure it is operating correctly and there are no problems with starting, if everything is in order, we conclude: replacing the VAZ 2108 ignition switch with your own hands was a success!

Installing silent door locks

Silent devices, unlike factory models, have a different operating principle. They have a latch installed, the same as in foreign cars. Closing is quiet and locking the door is effortless. The kit consists of two elements: one is fixed into the door frame, and the second is bolted to the post. When the door closes, the two halves create a single mechanism and interlock.

Reliability is ensured by a plastic coating. This is what allows the device to operate silently. The device consists of a cylinder, a rod, and a locking button. The lock is designed in such a way that no additional adjustment or cleaning is required. The fixation of individual parts is reliable, so even over time they do not become loose.

Installation will require preparing a room where there is an outlet and a vice. Required tools:

wrench;
overlay;
open-end wrench;
drill;
hammer;
drill;
file;
pliers;
metal files;
hardware;
Screwdriver Set.

In addition to the lock, a special lock is purchased that will be attached to the door post. Additionally, latches for the lock are purchased, since when removing the casing, the factory elements often break. Algorithm of actions:

Unscrew the handle.
Remove facing material.
Disconnect electrical wiring.
Gain access to the lock after removing the rod.
Dismantle the old mechanism and install a new one.

After the new device is inserted, the fasteners are fixed. Using a drill, a small hole is drilled in the end of the door to install the adjustment. It is secured with long bolts. Sometimes filing of the edges is required. After the fasteners are tightened, the functionality of the lock is checked.

Central locking (CL) on the VAZ 2107 is installed for the purpose of simpler and more comfortable operation of the car, making it possible to lock and unlock the door using a key fob. To install a central locking system on your car, you will need to purchase a set of equipment consisting of four actuators (drives), a remote control and a control unit (CU), wiring, fuses and brackets.

To install the central lock on the “seven” you need to prepare the necessary list of tools:

drill;
set of drills;
screwdrivers;
pliers;
wire cutters;
self-tapping screws 15–20 mm with a flat head;
rubber tubes, corrugations;
male/female terminals;
heat shrink tube for insulating wires.

Before installing the central locking system, remove the negative terminal from the battery, after which we perform the following steps:

Remove the decorative door trim.
Before fixing the actuator, we bend the bar along the door profile, mark and drill holes for the screws.
We attach the servo drive to the door.

Removing old locks

To remove the old lock, you need to unscrew the five bolts located at the end of the door. They hold the lock itself and the window lifter guide. After this, we remove them, freeing the locking mechanism from the latches of the lock drive rods. The plastic fasteners for the rods and pushrods can be snapped off using a flat-head screwdriver

Exposure to them must be carried out with extreme caution so as not to damage them. The last step before installation is to remove the external opening handle

It is removed by unscrewing the two nuts holding it on the inside of the door. It is more convenient to unscrew them using a socket wrench. After this, the handle can be freely removed from the outside. Now everything is ready to install new locks.
