Operating principle and self-repair of the door lock on a VAZ 2107

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:

Option #1. Before adjusting the doors, you need to make sure that the parts of the product do not have critical wear. The front and rear locks have a similar design, so the adjustments are identical for them. It is necessary to begin work by unscrewing the three bolts that secure the mating part of the lock located on the rack. Once the bolts are loosened, you can proceed. To do this, the mating part should be visually positioned so as to obtain the optimal position. Afterwards, it should be slightly tightened and checked; if the door does not close, then it is necessary to slightly lower or raise the position of the counter part. If the closed door protrudes, we move the counter part inside the car; if it falls inside, we push it out. It is necessary to adjust little by little, until the most optimal moment.

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.

Design of silent locks

Silent locks, unlike factory locks installed on VAZ 2105, 2106, 2107, have a completely different operating principle. They work on the latch principle, which is how locks on modern foreign-made car models are designed. The design of this lock allows it to close the door quietly and with minimal effort; it is quite easy to press the door with your hand.

Single door installation kit. Consists of two parts that are installed on the door and a receiving bolt

The castle consists of two parts. During installation, the inner part installed in the door is connected to the outer part with bolts, forming a single mechanism. The lock control rods from the door handles, locking buttons, and lock cylinders are connected to the inside of the lock. The outer part is responsible for engagement with the lock retainer installed on the car body pillar.

Video: the result of installing silent locks on a VAZ 2106

An additional advantage of these locks over factory ones is provided by covering the outer part of the mechanism with a plastic shell. This allows the lock to operate absolutely silently, hence its name. The absence of rubbing metal surfaces does not require regular cleaning and lubrication of the lock, which has a positive effect on the service life; the owner does not need to worry about the reliability of the locks. The lock closes the door tightly and holds it well.

The lock is installed in place of the standard lock with minor modifications

Which lock to choose for installation

Factories and cooperatives have long been producing silent locks for various car models. Some automakers have even begun installing them on production vehicles. Thus, Volga cars, VAZ 2108/09, VAZ 2110–2112, VAZ 2113–2115, VAZ 2170 have already acquired silent locks. On the market you can choose a lock model suitable for your model with minimal modifications. Locks adapted for installation on VAZ 2105, 2106, 2107 are not produced by factories, so car enthusiasts, over time, have developed ways to install locks from other VAZ car models. Later, cooperatives began to produce sets of locks intended for installation on these VAZ models.

The cooperative kit includes adjusting plates, rods and bolts. The kit is installed on all 4 doors

Kits manufactured by cooperatives cannot boast of a guarantee of quality, however, the presence of all the parts necessary for installing locks undoubtedly attracts the buyer.

But if you consider that low-quality kits will still have to be modified during installation, then you should pay attention to high-quality factory locks manufactured at factories in Dimitrovgrad, PTIMASH, FED and others

These locks will last longer and will certainly not cause any inconvenience during operation. Having spent time installing a factory lock, you will independently determine what additional elements are needed and will be preferable for your car; the lock will be installed with high quality and will last a long time.

On the VAZ 2105, 2106 and 2107 models you can install a lock from any VAZ model with silent locks. The most popular choice among car enthusiasts who decide to install a silent lock on a “classic” is the lock from the VAZ 2108 car.

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 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:

It is important to ensure that the front shutter position switch along with the wiring harness connector is connected correctly.

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.

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.

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:

1. 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.
2. Special spacers are fixed, which prevent the teeth from deforming or moving to the side.
3. 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.

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.

Vehicle inspection and preparation for work

Incorrect position of the front door, as well as the rear door, can cause it to not be locked correctly. The adjustment begins with a thorough inspection of the car, which is performed in the following order:

1. The door closes with a slight push; if the lock does not work completely, this indicates that the receiving part is in an incorrect position.
2. Using a regular ruler, we measure the gaps between body parts; in opposite parts they should be the same.
3. We stand at some distance along the path of the VAZ 2107 car and look along the side surface. From this angle, the failure of the part relative to other parts or, on the contrary, its bulging, is clearly visible.

Door adjustment involves correcting identified deficiencies by slightly shifting the part in the hinges and aligning the lock and its receiving plate. To perform this operation, you will need an impact and regular Phillips screwdriver, a hammer and a “10” open-end wrench.

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.

Materials for upholstery

When choosing fabric, you need to take into account quality, wear resistance, price, and color. The fibrous structure should stretch, this will allow the fabric to be securely fixed to the panel. Possible varieties:

• Genuine Leather. It looks beautiful, but is expensive. Creates sound insulation and withstands humid and harsh climates. The ease of care is dictated by the fact that the fabric does not absorb dirt and does not deteriorate when using aggressive detergents.
• Eco-leather or substitute. It has high wear resistance and is durable. The characteristics are identical to the natural base, only the substitute does not tolerate the effects of chemical detergents. With improper care, microcracks appear, which are then filled with dirt.
• Alcantra. Consists of thin and viscous fibers. The material has a high rate of moisture rejection, so it does not shrink. After the Alcantura is stretched on the panel, it will take the shape of the structure and will not sag over time. There is only one minus - the low level of sound insulation.
• Vinyl and leatherette. They provide strength and durability, and they are also very convenient for reupholstering. The material transmits sound well, so you will need to install an additional layer of insulation.
• Carpet. This is an artificial automotive fabric. This lining will last for many years. It withstands temperature changes, repels dirt, cleans quickly, and blocks the growth of fungus.

Some car enthusiasts are experimenting and upholstering door panels with velvet and even faux fur. Such fabric will partially create sound insulation, but will cause difficulties during cleaning.

Doors VAZ 2107

VAZ 2107 doors are a car part that is designed for entering and exiting the vehicle. In addition, this hinged body element ensures the safety of the driver and passengers by preventing them from falling out while driving. "Seven" is equipped with four doors - two on each side.

How to remove a door

Sometimes it becomes necessary to dismantle the door on a VAZ 2107, for example, for repair or replacement. At first glance, it may seem that there should be no difficulties in this event, but in fact the situation is somewhat different. The fact is that it is almost impossible to unscrew the fastener with a regular screwdriver. Therefore, you have to use an impact screwdriver.

An impact screwdriver is a special tool that allows you to loosen and tighten fasteners with great force by striking the end of the screwdriver with a hammer. Despite the fact that turning the bit in the desired direction is 1–3 mm, this is quite enough to tear the fastener out of place.

The list of tools may differ and depend on the method of dismantling. The main tools include:

• impact screwdriver with a bit to fit the screw;
• hammer.

Having prepared everything you need, you can start working:

1. Remove the door stop.
2. Using an impact screwdriver, we tear off and unscrew the fasteners.

If you cannot unscrew the fastener using an impact screwdriver, you can try to drill out the head of the screw with a drill of a suitable diameter (6–8 mm), and then use narrow-nose pliers to unscrew the fastener. Another option is possible: a bolt is welded to the head of the screw and using a wrench they try to rip the screw off.

How to adjust the door

The door on the VAZ 2107 must be installed level and without distortion relative to the doorway. The gap between the body and the door element should be the same on all sides. However, over time, the door begins to sag, i.e., a misalignment occurs, which is due to wear and tear on the door hinges. If there is play or the gap is set incorrectly, the problem must be corrected by adjustment. Otherwise, the door will close with great force. To carry out adjustment work, you will need the same tools as when dismantling the door.

Door adjustment consists of two stages:

• hinge adjustments;
• lock adjustment.

To adjust the position of the door element, perform the following steps:

1. Break off the fastenings of the door hinges with an impact screwdriver.
2. The door position is set (lowered or raised) in order to correctly adjust the gap between the body and the adjustable part.
3. Tighten the fasteners.
4. Check the position of the door.
5. If necessary, the adjustment is repeated.

Disassembling the door

There are situations when it is necessary to disassemble the door of the “seven”, for example, if the sliding glass, the body is damaged, or if the door itself is repaired. To do this you will need the following tools:

• screwdrivers (flat, Phillips);
• key to 10.

The disassembly process itself boils down to the following steps:

We take out the decorative plugs on the armrest handle, unscrew the fastening screws and remove the handle.

Door stop

The door stop of the VAZ 2107 plays the role of a latch, i.e., it prevents it from opening excessively. Over time, the limiter may fail, requiring replacement. For this you will need:

To dismantle the lock, first remove the door trim. Then perform the following steps:

Using a hammer and a punch, knock out the door stop pin.

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.

Door lock VAZ 2107

The VAZ 2107 door lock is a part that rarely fails. However, over time, this mechanism may need to be repaired, replaced, or adjusted.

Working principle of the door lock

The “seven” door lock consists of a locking mechanism, a key cylinder, external and internal handles that allow you to unlock the door from the outside and from the passenger compartment, as well as buttons for locking the car from the inside. The lock is controlled by transmitting force using rods. The main element of the lock is a rotor with a slot. When the door is locked, it goes behind the opening bracket. When the door closes, the bracket presses on the latch, as a result of which the ratchet is activated and the rotor rotates. When part of the bracket enters the rotor slot, thanks to the springs it returns to its original position, thereby pressing the door.

Door hinge repair options

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

1. Complete door replacement. It is complicated by the fact that it is not always possible to find new VAZs for old ones. You have to buy old elements that are partially worn out.

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.

Door handles

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 handle

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.

Which ones can be supplied?

On the “seven”, in addition to the factory external door handles, you can install European handles. This procedure refers to car tuning, which allows you to change the appearance of the car, giving it an attractive and modern look. The essence of the process is to dismantle the standard handle and install a new part in its place, which fits without any modifications.

How to remove a door handle

To replace the external door handle, you will need to prepare the following set of tools:

• socket wrench 8;
• flat screwdriver.

The dismantling procedure consists of the following steps:

Raise the door glass all the way.

How to install a door handle

After removing the old handle, you can begin installing the new part:

1. Lubricate the rubbing areas with lubricant, for example, Litol-24.
2. We install all dismantled parts in the reverse order.

Interior door handle

In most cases, the internal door unlocking handle on a VAZ 2107 has to be removed when dismantling the lock or when replacing the handle itself if it breaks, which happens extremely rarely.

How to remove the handle

To remove the inner handle you will need a flathead and Phillips screwdriver. Dismantling is carried out in this way:

1. Remove the door trim.
2. Unscrew the 2 screws securing the handle.

How to install

After dismantling the old product, we begin installing the new part:

1. We put the rod back on the handle, for which there is a fixing rubber insert.
2. We fasten the handle and reassemble the dismantled elements in the reverse order.

Replacing the door and door stop

Before replacing the door, it is advisable to disassemble it. In this case, the door will be lighter and adjusting it will not be difficult. And you can assemble the door after hanging and adjusting

Removing the upholstery and door lock is discussed in the article - “Replacing the upholstery and door lock.”

Removing the glass and window regulator is discussed in the article - “Replacing glass and window regulator”.

Use a hammer to knock out the door stop finger through the bit.

Use a 10mm wrench to unscrew the two bolts...

...and remove the stopper from the inner cavity of the door.

Hold the door and use a Phillips impact screwdriver to remove the five screws.

In some cases, it is difficult to unscrew the countersunk screws that secure the door hinges.

In these cases, you can drill out the screw heads with a 9 mm drill.

After removing the door, the remaining parts of the screws can be easily unscrewed with pliers.

...and remove the door from the car

Having installed the new door, we adjust its position in the opening.

Installing a central door lock on a VAZ 2107

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:

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

When installing the lock, it is recommended to lubricate all rubbing parts with lubricant, which will ensure trouble-free operation of the device.
