All ways to solve the problem when the rear doors on a Lada Grant do not open well

Sequence of actions when replacing the rear right (left) door handle

We carry out the work modularly, since initially it is necessary to dismantle the casing, the internal filling, and unscrew the handle latches.

Stage No. 1: dismantling the card.

1. We place the car on the site, provide priority safety measures, and activate the parking brake.
2. Open the rear left door and raise the glass to the top position.

3. We twist the blocker (soldier).

4. Use a screwdriver to pry up the fastening of the window lifter handle, remove it from the grooves, and remove the lock.

Stage No. 2: disconnect the door lock rod and remove it from the door cavity.

1. Using an “8” socket with an adapter, unscrew the bolt securing the handle.
2. Using a screwdriver, carefully pry and disconnect the lock bars from the inside.
3. We move the handle in the “forward” direction and remove it.

This completes the process of dismantling the unlocking element. Next, we carry out preventive maintenance, install new parts, and assemble the structure in the reverse order.

Adjusting the gap between the bumper and the trunk lid

1. For this purpose, you can use plasticine in the area where two surfaces come into contact. We make a small ball and glue it to where the bumper and the cover meet.

2. Next, close the trunk lid according to the manual: we lower the lid freely from a height of no more than 20 cm.

3. The gap is adjusted by moving the trunk lid lock latch. Upon completion of the adjustment, the position of the buffer and trunk lid are adjusted.

Recommendations for selection

Without a doubt, when choosing, give preference to parts with factory catalog numbers. Purchase consumables exclusively from official representative offices, service stations, and auto stores.

Before purchasing, check the catalog numbers of parts with the actual data specified in the operating instructions. If such a book is not available, seek advice from service center specialists, download recommendations from the Internet.

# 15 Locks & limiters - new model (liftback / Kalina 2)

Accordingly, the handle is now different, I took a Chevrolet from the Niva, purely because of the eye, it doesn’t fit in the seats**.)) Therefore, I had to knock out this fastener and rearrange it on the Grant handle, there were no Kalina 2 and Grant liftbacks in stock =(

Tightness :DD Oddly enough, they were found at the same analysis.)

__ I also purchased limiters from the liftback:

Actually, that’s the problem with them, these white plastic caps wear off and the spring starts to work inappropriately:DD _

Step-by-step instructions for dismantling the rear right (left) door lock on a Lada Grant

We carry out the work modularly: dismantling the card, removing the internal filling, handle, lock.

1. We repeat the previous steps.
2. Using a screwdriver with a Phillips bit, unscrew the fastening of the intermediate lever of the locking rod and move the base of the lever.
3. We remove the locking tab from the standard hole.

We lubricate the moving mechanisms, install a new lock, and assemble the parts in the reverse order.

The rear door lock cannot be repaired if it shows signs of deformation of the housing.

Adjusting the rear door lock

The doors are difficult to open, the lock is jammed, an extraneous squeak appears when unlocking - the first signs of the need to adjust the door lock. The problem is common among domestic transport.

The left side wears out prematurely due to frequent use.

Inexperienced owners practice eliminating damage by lubricating the mechanism. However, the effectiveness of such a solution is low. Service station technicians recommend the following adjustment:

1. Loosen the bracket using an impact screwdriver.
2. Move the bracket up (down) a few millimeters, while simultaneously trying to slam the door.

   
   We move the mechanism a few mm and check for functionality

3. As soon as we achieve the result, we firmly fix the bracket.
4. Lubricate the rod with a thin layer of Litol, graphite lubricant.

This completes the adjustment of the rear door locks.

The above algorithm is effective provided the lock is in good condition. What to do if there is a curvature or deformation on the door frame? In this case, the experts advise making improvements:

1. We open the back door.
2. We insert a plastic stopper into the lock so that it does not close.
3. Using a triangular file, carefully file off the sharp ends of the lock teeth. We do this carefully so as not to break the mechanism.

   
   The place to be filed with a file

4. We remove the plastic stopper and check that the mechanism is working properly.

Along with adjusting the lock, you have to adjust the door. The reason is the increase in the radius of curvature of the frame. The defect is common and can be corrected by straightening the curvature.

No special tool is needed, the strength of the hands of the master (repairman) is enough.

Since 2015, AvtoVAZ has launched mass production of rear door locks of a new type on the Lada Grant. This is a modernized version of the previous locking mechanism.

The main difference is not only in cost, but also in the change in design and the use of durable polymer. This made it possible to significantly reduce the knocking sound when hitting a metal loop.

Reviews

Conclusion The door lock is replaced only if it is damaged, deformed, or defective. The design of the mechanism is not complicated, and the operating principle is intuitive.

general information

On machines equipped with Norma, central locking control units are installed, which are replaced with new ones if they break down. On Luxe vehicles, TsBKE are used instead. Below we will try to take a more detailed look at the central locking unit and its control unit, their relationship with the remote control, symptoms of a malfunction of this part, and also provide instructions for replacing it yourself.

Now let's look in more detail at remote control, which is intended not only for locking and unlocking car doors at a distance with synchronous activation of the security mode. In addition, it allows you to lock all locks with one turn of the key, lock and unlock all door locks by pressing one button located inside the cabin, and also turn on and off the car alarm both remotely and with the key.

Operating modes

Door locks on Grants are blocked by pressing the corresponding key on the remote control, after which they can be unlocked using the remote control in stepwise and simultaneous unlocking modes. The first of the listed modes will allow you to unlock all door locks by double pressing the key (first the driver's door is unlocked, and then all other doors). When you activate the second mode, you can unlock all the doors of the car at the same time, with one click.

To change the mode, the car owner will need to perform the following steps:

• first you need to turn on the ignition with the remote control key;
• then you will need to press and hold the unlock and lock keys in this position for five seconds;
• After the buzzer sounds, release the keys.

Blocking

If, after unlocking the door locks, you do not open the trunk or one of the doors, or do not turn on the ignition, then after twenty-five seconds all doors will be locked again.

Control from the cabin

When blocking doors directly from inside the car, you need to press the corresponding button located on the driver's door, or press a similar button in the module of the same door. Unlocking will require lifting the desired key on the door or pressing it in the module. To lock the doors from the outside, you will need to turn the key in the lock located on the driver's door clockwise, and to unlock the doors, turn the key in the opposite direction.

How to adjust doors on Lada Granta

Difficulties with the operation of the door lock are caused by its design, which is very demanding on the correct adjustment of the door to the doorway. To adjust the door we will need to do several sequential steps.

The first thing you will need to pay attention to is the gap between the top edge of the door and the gutter. The optimal gap should be such that a credit card can fit through. In this case, there will be a balance between aerodynamic noise and the tightness of the door to the drain. If your gap is smaller or larger, you will need to change the door profile. If your gap is smaller, then lower the glass all the way down, close the door one click and, grasping the upper edge of the door, pull it towards you several times, using some force. If, on the contrary, the gap is larger, then we open the door, and, with the window down, resting our knee on the door trim, we pull the top of the door towards ourselves, towards the passenger compartment, several times.

Next, we move on to solving the main problem of the lock’s tight operation. Most often, the door does not open or close well due to the door opening being too tightly attached to the seal and the lock's return hinge being installed incorrectly. To work we need an impact screwdriver. We loosen the hinge on the body and move it in the desired direction, tighten it slightly and try to work the door. If there are improvements, we act in this direction.

As a result of movement of the door lock hinge, the gap between the door and the body may be slightly compromised. If the door protrudes slightly outward, you need to lay a soft but durable gasket in the door opening and the central pillar in the area of ​​the door hinges and simulate the closing of the doors, thereby giving the door the desired profile. If the door, on the contrary, has deepened relative to the body (which happens extremely rarely), placing your knee on the outside of the door, in the area of ​​the hinges, we pull the open door towards us, towards the street.

By following this simple adjustment method, you are guaranteed to achieve smooth operation of your doors, without side effects.

If the hood comes back

In the case when the hood opens backwards, the situation becomes quite complicated. The most obvious and easiest way to open such a hood is to get to the lock mechanism through the air intake openings. Naturally, they must first be protected from scratches and chips with electrical tape, or the working tool must be wrapped with it. If the air intake grilles are removable, the best solution is to remove them (if possible). This way you can have excellent access to the lock and open it quickly.
