Door lock device VAZ 2107

Door locks hold the door in a closed position and prevent it from opening spontaneously while moving. The doors should be level, without distortions. The gaps between the door and the body must be the same around the entire perimeter. Otherwise, adjustment of the VAZ 2107 door locks or repair (replacement) of door hinges is necessary.

Important: it is useless to adjust the doors with faulty door hinges. Therefore, if they have play or are positioned incorrectly, the problem must be corrected. The VAZ 2107 doors should be adjusted after replacing or adjusting the hinges. Otherwise, the door will not close easily, even if it is fixed evenly with ideal gaps.

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.

What problems arise with doors

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”. Diagnostics involves checking, lubricating and adjusting the locks of all devices on a VAZ 2107 car. We will find out in more detail how to adjust, as well as what details you should pay attention to.

Features of adjusting the gap and hinges

Adjustment does not require special knowledge, but it will require enough time to accurately set the locks, hinges and gaps. Initially, you should pay attention to the lock mechanisms, as well as diagnose the condition of the gaps between body panels, front fenders, as well as racks and frames. We also recommend that before starting work with the adjustment, it is good to clean and lubricate the lock mechanism and the mating part; sometimes this solves the problem of poor closing and further work becomes unnecessary. The gaps on the VAZ-2107 car sometimes reach 7 mm, which, by the way, is not a rare occurrence. If you cannot set a stable gap (no more than 3 mm), then there is nothing to do, you should proceed to the stage of adjusting the hinges.

Release the hinges using an impact screwdriver

In order to adjust the hinges on the VAZ-2107, you need to use a Phillips impact screwdriver. The hinges are adjusted either in pairs or only one, which depends on where the door is skewed. When adjusting them, you need to pay attention to the condition of the seals; if they no longer perform their functions, they need to be replaced. When adjusting the hinges, it is recommended to lubricate them and eliminate any play.

Features of lock adjustment

It is necessary to begin adjusting the door locks of the VAZ-2107 with troubleshooting. To do this, you should initially inspect the mechanism, and then lubricate the crossbars. There are two options for adjusting the locks on the “seven”. Let's consider both options:

Before carrying out work, you can use a pencil to outline the contour of the mating part. The original location of the product should be used as a starting point when carrying out adjustment work using any of the options described above.

Adjustment is not particularly difficult, but requires special precision, so be patient and get to work. If you still cannot adjust the locks on your car acceptable, go to the nearest auto body repair shop and they will help you.

Silent locks and their installation

Silent locks for "nine"

Adjusting the doors also means upgrading the locks, which do not make a very pleasant sound. It's not even a sound, but a loud, unpleasant metallic clang. It turns out that it's all about the design of the door locks. So, on the “Nine” and other cars of the AvtoVAZ family of previous years, the lock is fixed on the outside of the door. As a result, all parts that come into contact with the lock are bare metal, which makes such unpleasant sounds.

To eliminate this mistake of manufacturers and modernize the doors, you need to purchase domestically produced silent locks.

Let's get started:

We arm ourselves with an impact screwdriver, since a regular one will definitely not be able to remove the bolts, which are tightened very powerfully. You'll have to tinker, but the result is worth it;
In place of the unscrewed bolt (one for now), you need to insert a pin. This is done so that the inside of the lock does not fall inside the door;
We remove the old lock and install a new silent one in its place. The bolts will need to be tightened with maximum force, and then be sure to tighten them with an impact screwdriver.

The VAZ 2107 doors should be adjusted after replacing or adjusting the hinges. Otherwise, the door will not close easily, even if it is fixed evenly with ideal gaps.

Adjusting the door lock of a VAZ 2107 – Br Gavs

On the VAZ 2107 “Seven” the doors are a separate matter; on new cars the doors close a little tight, because The seal in the door opening is NEW AND UNACCEPTABLE, like for example in a car 2 or 3 years old, so adjusting the doors on a VAZ 2107 costs from 100 rubles and more.

The difference between the lock of the VAZ 2107 and the VAZ 2106.

The “six” (Niva) has a ring on the lock itself that rotates, which makes closing the door easier; the “seven” has this ring welded to the rear, i.e. it does not rotate, making it difficult to close.

The main problems with locks and doors in the VAZ 2107

The handles are the most problematic areas for locking the front and rear door alarms.

Let's look at the problems with handles. In fact, the original hands of the “Seven” are not even bad at all. The main thing is to lubricate them in time, with silicone or any other lubricant that does not allow the mechanisms to dry out and begin to jam. The problem of opening the doors is the insufficient work of the rod from the handle; it can be eliminated by bending the main rod of the handle; you should not overdo it; after bending the rod, lock the lock with two clicks and check the alarm or lock the door with a key. If the car is closed, then it’s good, if not, loosen the bend of the rod.

Replacing pins in hinges

So, if the repair only involves replacing the fingers, then the first thing you will need to do is remove the door to gain access to the hinges (3-4 fasteners are simply unscrewed, depending on the model). Next, the fingers are knocked out. If they do not come out due to corrosion or deformation, then you should first thoroughly fill everything with WD-40 to remove the rust and repeat the operation. If this fails, you will have to drill out the pins or replace the hinges completely.

When installing new pins, be sure to lubricate them with grease or oil, and after installation, adjust the door (lower or raise it a few millimeters through a tightening rod). The door should fit accurately into the catch when closing without additional physical effort. Otherwise, the wear and tear on both doors and hinges will be much higher. After 1-2 years of such operation, you will have to completely replace the door along with the hinges.

The main difficulty in repairing VAZ door hinges is to correctly knock out the pins (the same fingers). It’s most convenient to just rivet it and then straighten the loop if necessary. The most aesthetic method is to drill out each end of the finger, after which its edges are ground off or simply squeezed. The drill is immediately taken to the minimum size, then gradually increases literally by millimeter. This will take quite a lot of time, but the loop will not be damaged.

If the finger has other deformations, it may be necessary to make a through hole through the pins. This will not prevent the use of new fingers in the future. For this purpose, either an impact screwdriver or a powerful drill with a high-quality drill bit (carbon steel is ideal) will be useful.

The main problems of VAZ 2107 doors

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.

Door hinge repair options

Failure or severely deformed hinges are repaired using the following methods:

Replacing door hinges, as well as fingers, is the most rational option in this case. It's inexpensive and relatively easy to do. If necessary, additional equipment can always be rented at a service center or automotive supply store. The cost of the hinges themselves for the VAZ 2110 and similar models is only about 300-500 rubles. You can also find old, used ones for sale. You will have to pay less for them. But new VAZ 2110 doors will cost several thousand rubles. And they are sold, as a rule, without glass and cladding. Their installation is an additional waste of money.

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 Tolyatti. In fact, the gap can be from three to seven or more millimeters. Regardless of its size, the main thing is uniformity. If even with the lock removed it is not possible to establish a stable gap, you will have to adjust the hinges.

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. When the gaps are set, you need to pay attention to the door contact planes. In this case, you will also have to play with both the hinges and the seals. Only after this, after lubricating the hinges and eliminating the backlash, can you begin to adjust the lock mechanism itself.

Practice, we change it ourselves

Logically, the first thing you need to do is remove the door from the car; this can be done using an impact screwdriver or a semi-automatic machine. After dismantling the door, it is necessary to place it on a previously prepared, flat surface covered with fabric. This will help you avoid scratches, since repairing a canopy involves the use of an angle grinder and welding, do not forget to cover the visible painted surface and be sure to! glass!

The patient is placed, protected, it’s time to start :) The first thing you need to do is try to pull/knock out the finger from the canopy, and if that doesn’t work, then cut through all 3 parts of the canopy with a thin grinder circle (1.6mm, I think), as in the photo.

We cut it with a grinder like this if we can’t knock out a finger

This thread will make it possible to loosen the fit of the finger in the loops, and even if there is significant wear in the loops, it will make it possible to compress the loop to the required size. After cutting through the canopy, you can try to knock out the finger using a tool. If you still fail to do this, then you need to take a thin chisel and slightly widen the groove by hitting the chisel into the groove. Now we should try to knock it out, we succeeded.

Next we need something that has practically nothing to do with the body - a valve from the engine. For what? And then, the diameter of the rod is ideal for the role of a canopy finger. Here we try it on:

Now you need to press the canopy onto the valve stem using a hammer. Here you need to do everything in moderation, you shouldn’t tighten the canopy too much, the rod should move with slight pinching, you need to leave a small gap for welding. Once you achieve the required pinch, you can cut the rod to the required length and weld the thread.

As for welding, here it is necessary to weld on a lower current; it is very important not to weld the canopy with the rod in a heap. That’s why I cooked on a low current, the semi-automatic was slightly “greasy”, but the main thing was not the beauty of the seam, but that it held the thread reliably. Excess metal can be sanded with a grinder.

Thanks for subscribing!

Also an important note about the finger. In the factory version, there are two grooves on both sides of the pin, which are designed to improve lubrication and self-removal of sand.

I don’t have the polished version, since in this case it doesn’t matter at all.

Please don't look at the quality of the seam, I was training

It's almost ready.

Don’t care about the seam, as in the previous version)))

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.

When adjustment is needed

Certain symptoms will indicate that door adjustment 2107 is needed:

The door may sag, sag, or move to the side.
The appearance of serious gaps along the entire perimeter of the body part.
Difficulty closing. This action does not occur with a dull sound, but with a loud feedback.
If the lock does not close well, then the reason is not necessarily the mechanism of this device. Incorrect operation of the closing device is sometimes caused by incorrect door position.
Displacement of the lock and latch.
Raising or lowering the structure when closing.
Poor locking in the closed position due to the latch inside the handle.
Random door opening while driving.

To visually determine the need for adjustment, you can inspect the car; if there is a problem, it will stick out a little. In order not to rely only on your eye, you can take measurements; they should be the same on both sides.

External handles and solving problems with them

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. Seven handles, unlike handles 2101-2106, have the nasty property of cracking. Even slight damage on the painted black side can indicate this. This defect cannot be treated and the handle is completely replaced.

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. All work on the door element can be done in a garage with a minimum set of tools.

Replacing door hinges (VAZ Classic)

Since the car is from 1986, the driver's door hinges are tired, especially the bottom one, and the door sags accordingly. Not every straightener undertakes to replace hinges; they mostly offer door replacement, although now it’s not easy to find a good one

door, and in this door I have changed a lot. In general, replacement is not my option, I decided to change it myself and, as it turned out, there are no difficulties in this, everything is simple and quick. I ordered the hinges here > Avtoall First, I disassembled the new hinges, cut off the rod on one side with a grinder and knocked it out

The part that is intended to go inside the door is thrown away. Then I removed the door, capped it and drilled with drills in increasing order

After the old rod is drilled in the middle, the remains are knocked out in different directions.

Since I started covering my car with film, I covered the new hinges with film and put them in place. To prevent the rod from falling out, I welded it on top with a drop of welding. The top hinge was not very worn, but the bottom hinge, which is welded into the door, was also worn out, so I welded the rod on both sides and the play disappeared completely.

Next, I refined and put the door in place; I had to spend some time setting up the gaps, because... I installed it for the first time, but in the end everything was perfect, no sagging, the gaps were even, and I started installing silent front-wheel drive locks on an almost new door, but that’s another post.
