How to remove the front door lock of a Lada Granta

Front door lock device

A Lada Granta driver's door lock costs from 1000 to 1500 rubles. The price in official dealer stores is lower. To replace it, you need to remove the interior trim, disassemble the steel block and remove the core. The larva must be repaired or replaced. Sometimes it is enough to lubricate the pins with a silicone substance for the part to function properly.

The pins that fit into the slots on the right and left create a specific coding when the key is turned. Blocking occurs after prolonged wear, a sharp change in temperature, rust on the teeth or a broken pin. The lock can be easily opened with a master key or breaks if not properly maintained. Repair work may be required after unauthorized opening by a foreign object, wear of individual parts, freezing of moisture in the mechanism, or improper operation. By purchasing a set of larvae, a person receives a core for the driver's door and trunk.

Prerequisites for failure: creaking, problems when the key moves in the lock or penetrates the core, damage to the body of the cylinder.

Replacing the rear door lock

Having untwisted the cylinder, it will become clear what actions to take. If the teeth are broken or deformed, then repair work will not yield results. You will have to remove the cylinder and install a new one. It is necessary to change the Granta rear door lock according to the following scheme:

Now you can look at the condition of the internal parts. If there are no external signs of malfunction, then the lock teeth are thoroughly lubricated with a silicone substance. If a break is detected, a new core will have to be installed. Assembly is performed in reverse order.

Preparatory stage

Required tools:

• impact screwdriver;
• cross bits;
• pliers;
• plastic clips in case of damage to the standard ones;
• liquid for removing rust and corrosion;
• a new lock, the modification is chosen individually by the owner.

Procedure for independently replacing the driver's door lock on a Lada Granta Liftback

1. We install the car within the perimeter of the repair area and provide unobstructed access around the perimeter.
2. We take priority safety measures when carrying out work. We fix the rear row of wheels with wheel chocks and engage first gear to avoid arbitrary movement.
3. Open the driver's door, use an impact screwdriver to unscrew the two screws securing the shackle to the car body, and remove it from its seat. We install a new shackle with soundproofing material.
4. Let's start removing the constipation: unscrew the plastic float and remove the stem.
5. We unscrew the car door card, two screws, eight plastic clips around the perimeter.
6. We disconnect the block with wires from the double-glazed window control unit, speakers, and central locking.
7. From the outside, unscrew the three screws that secure the lock body to the door.
8. We remove the two rods, having first disconnected them with pliers.
9. We carry out preventive maintenance, clean the seat, remove old grease, and apply a thin layer of new one.
10. Let's start installing the new lock.
11. We assemble the structure in the reverse order, unless there are other breakdowns that require surgical intervention or elimination.

During the installation process, we pay attention to the integrity of the electrical wiring, insulating layer, terminals, and blocks with wires. If there are signs of wear, replace them with new ones.

Do not operate the machine with faulty electrical wiring.

Typical door lock malfunctions

• tightness of locking the door;
• increased noise when opening/closing;
• the central lock does not lock the door and does not respond to signals;
• unlocking is accompanied by a creaking, metallic grinding sound;
• While driving, the door vibrates, cracks are visible in the places of contact with the standard seal.

Common Causes of Premature Wear

• failure to comply with the deadlines for technical inspection, preventative maintenance, lubrication, and replacement of worn elements;
• third-party mechanical damage resulting in deformation of the door or lock;
• manufacturing defects at the factory;
• the lock has become loose due to loosening of the fastening;
• violation of the adjustment algorithm;
• human factor: systematically locking the door with force.

The defect is eliminated by replacing the constipation assembly.

Replacing the rear (passenger) door lock

The procedure for preventing locking of the front/rear passenger door is carried out by analogy. The design and method of fixation are typical.

Installing a trunk lock on Lada Granta Liftback

1. We place the car on a level platform and provide access to the trunk lid.
2. We take safety measures when carrying out work.
3. We unscrew two screws and remove part of the lower plastic trim of the trunk lid.
4. Unscrew the two screws securing the lock body to the trunk lid;
5. Using pliers, remove the rod from the button to the body.
6. We remove the constipation, carry out preventive maintenance, lubricate the threads and the rod end.
7. We install a new lock and assemble the structure in the reverse order.
8. We unscrew two screws, remove the standard shackle, install a new one with sound-insulating material.

Replacing the hood lock

1. Inside the car, under the dashboard, there is a hood release lever. We pull it towards ourselves.
2. Release the latch and lift the hood.
3. Using a TORX key set to “10”, unscrew the two screws holding the lock body to the body.
4. Using pliers, remove the cable eye from the seat.
5. We remove the lock, install a new one in its place, and assemble the structure again.
6. Lubricate the bow-clamp with silicone grease/solid oil.

Adjusting the rear door lock

You will need a screwdriver, hammer and file. The bolts that will help you make adjustments are located under the casing. After removing it, begin the adjustment. Instructions:

It is important to check the functionality of the device and only then perform reassembly.

If the problem does not go away: there is still a creaking or difficulty opening/closing, you can use another method. To do this, use a screwdriver to loosen the fasteners of the bracket and adjust it up and down. During this, close and then open the door several times. As soon as the creaking disappears, the bracket is firmly fixed.

Removing the side mirrors

Side mirrors are needed to monitor the situation on the road while driving. They are:

Interior mirrors are mounted in car interiors using self-tapping screws or bolts, suction cups, or glue. Regular bolts are simply unscrewed after first removing the plug. Care should be taken with the adhesive connection; first try to separate the bracket from the platform glued to the glass. In most cases, for these purposes, it is enough to perform a slight turn or carefully move the latches. When this is not possible, the bracket is dismantled along with the windshield. The glue holds the working elements very firmly, so you should act with extreme caution to avoid the risk of damaging the glass.

Before starting work, carefully read the technical operating instructions. The dismantling process should be strictly followed so that you do not have to buy new glass; its price starts from 500 rubles.

To remove and replace the interior mirror, presses and mediators are used. The case is divided according to a principle similar to a TV remote control or mobile phone. Find the area where the body and the mirror product meet, insert the spinner into the compartment and press firmly. There should eventually be a small gap on the body. Go over it with a pick and separate the parts of the body. Warm up the area where the reflector connects to the body with a household hair dryer and remove the mirror.

A construction hair dryer is not suitable for heating - it is too powerful.

How to get to the door mechanism

Replacing the Lada Granta door lock cylinder or the entire structure should be done by a master or someone who understands how to get to it. After removing the casing, access to the lock opens automatically. There is no need to remove the inner metal lining; the steel sheet is simply carefully bent to the side.

Always remove the car from the alarm before starting repairs.

A drive is a rotating part with a characteristic protrusion; you will see it after dismantling the casing. Replacing the larva is carried out in the following steps:

After assembling the mechanism, you should find the slot. A screwdriver is pushed into the space between the housing and the drive. If all else fails, the lock assembly will have to be removed.

How to remove the front door: step-by-step instructions

Lock device

The locking mechanism for the right and left doors of 2190 and other models is approximately identical. The larva looks like a cylinder equipped with a secret mechanism. In all locks with flat keys it will be replaceable.

The drive has a hole for removing the element. It is enough to press with an awl or a thin axle, you will be able to pull the knot out. The lock is usually removed first.

If you insert the key into the cylinder and turn it left and right 90 degrees, then removing the cylinder will be much easier.

Replacing the front door lock on a Lada Grant

Then the door lock on the Lada Granta with an electric drive is installed in the reverse order.

General practical information about the structure of the larva

If the main reason for the malfunction of the system is precisely the cylinder, it will be enough to correctly replace the cylinder from the inside. This will make it possible to do without completely replacing the element, and will also increase protection and allow you to install a new key instead of the old one.

Installing a new cylinder changes the mechanical design of the lock, so instead of the old key, you will need to make another one.

Reasons for replacing the lock cylinder:

Reviews

Conclusion If the need arises, you can replace the door handle on the Lada Grant yourself. The process is not complicated, and the principle of operation is intuitive.

Adjustment: procedure

To adjust the lock on the front doors of Lada Grants, first check the gaps on the sides, top, bottom and sides. Most often, problems with opening arise due to incorrect geometry - for example, the top of the door fits tightly to the drain and body. To adjust:

To correct the position from below, the doors of the Grants are opened and then closed with palm strikes. The gaps between the body and the door structures should ultimately be the same. No force is used to avoid damaging anything.

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.

The right door lock does not work. Research and search for the cause.

Over the last couple of months, a problem with the lock randomly not closing when arming the front right door began to bother me. For some reason, everything can be fine for a couple of days, but in the evening, when you arrive home, it just doesn’t close. I checked the connectors in the door and on the lock - everything is good and clean. According to the diagram, all three passenger door locks receive an impulse from one point, which means that the CBKE also disappears. In the end I decided to replace the lock. It was a two-pin one, without a limit switch, so I took the same one. Dear, bastard 2050 rub.

The replacement doesn’t seem to be difficult, but I cut my hands very well on the edges of the door. Putting it back together is more difficult than taking it apart, especially putting the rod back on the outer handle. After 20 minutes of torment, I spat and took off the handle. It is much easier to insert the rod through the hole from the outside.

I studied the old castle by its appearance. It turned out that the plastic casing of the electrical part had come off.

I dug further out of interest. I didn't see any obvious defects. A couple of theories arose why there might be a problem: 1) in addition to sealing, the cover serves as a clamp for the gear, and because the clamp is weakened, the gear can sometimes become warped, and therefore the lock does not work. 2) if the motor does not bring the pusher to the extreme position, then it will not click to close, and the return stroke will be idle. Maybe due to a lack of sealing, moisture or dirt has entered the motor, and it simply does not have enough effort.

UPD. Found. The motor jams for no reason. When it's jammed, you can't even turn it with pliers.

UPD2. Disassembling the motor revealed a foreign plastic particle inside the motor. At the moment when it fell into the gap between the rotor and stator, the motor did not work. After that, the reverse rotation pushed her out again. Presumably the particle was part of the plastic cap, as it matches it in color. It seemed to have fallen off from the place where it was thermally unfastened and got inside through the ventilation holes in the motor casing.

Replacing the front driver's door lock.

As I wrote earlier (www.drive2.ru/l/9292608/), my central locking bothered me. He just went crazy. Out of four doors, only 3 closed (all except mine) or, on the contrary, mine closed, but 3 didn’t, or even only the front doors closed and the back ones didn’t... In general, I suffered for 4 months until I waited for maintenance. At first there was a version that there was water in the end switches, and everything needed to be ringed and removed, but it turned out that everything was much simpler, the lock was covered. The service center said that the lock was ordered from the factory and will be replaced under warranty free of charge. But my troubles did not end there...

After waiting 2 weeks, I couldn’t stand it, I called the service, to which I was told that there was no information about it yet, they would clarify it and call me back. But alas. Silence... I called 2 days later - the answer was surprising:

- We didn’t order anything. We have everything in stock... - Well, you're in trouble... When should I come to change it? - Our master will call you back and set a date... - Well, ok, no questions asked...

Another 3 days passed. Well, as much as possible... I was infuriated, I went in person. Further more interesting)

— Hello, I need to change the lock on the door, I’ve been suffering for 5 months. They promised to order it, but it turns out it’s in stock... - Yes, we know. Wait. The master is not there yet, he will call you and set a time... - No need to call me. Now give me a time. - ... - Well, or give me a boy who will sit next to the car and make sure that nothing is taken out of it or stolen! - Oh, don’t worry so much! (the boy began to make excuses, blushing)... - After 5 minutes the master came, and we decided on the date... In general, I suffered for another week.

I arrived at the appointed time, and not everything went smoothly... They forced me to pay for the car wash. Well guys, warranty service... What are you talking about? It's your fault. Okay, ok... I waited 40 minutes for the car wash... I listened to music, sat like this, turned over, sat differently, took a few dirty photos of Chernykh... What else to do when no one wants to work... No comments.

They washed Chernykh for half an hour... The rugs were dirty, well done... They always washed them, there were no complaints... They changed the lock for 3 hours... For half an hour they dumped everything on the planning meeting... What are you talking about? Oh, AvtoVAZ... I had a better opinion... They entertained me as best they could, but for the first time in the service I was like this:

The lock was changed, I think it was most likely him.

I haven’t seen it personally and have no idea what it looks like. But after the replacement, everything works, the doors close both from the central locking and from the alarm. This makes me incredibly happy. Now I’m not afraid for the car... So, tinting was my salvation. Extra eyes can’t see anything and it’s very good). In the end, I only paid for the car wash. And the lock and the work are 1330 rubles

worth... O_o...

They washed us, of course, badly, but still better than it was)
