The topic of poor rear door opening is a very painful one for Grant/Kalina owners. It did not bypass almost any owner of the above-mentioned cars.
And so we will try for the hundredth time to understand the causes of this disease. You can find a lot of information on the Internet about how to make the rear doors work. We will try to list the main operations that are recommended to be performed for better opening of doors: 1) Adjusting the lock, or rather the response “ear”. This needs to be done first, but it will not give a strong result, although it is very important. 2) Bending the door in one way or another. Many people achieve very good results, but some consider this method too barbaric or are simply afraid to do it, and there are no known masters. 3) Grinding the tooth in the lock. There is an effect, but not great. And if you overdo it, the locks will unlock spontaneously.
However, I almost never came across any information about why this actually happens. The front doors have exactly the same locks and they open perfectly, so why is it not so with the rear ones? It’s enough just to understand the design of the front and rear door opening mechanisms and understand what their differences are. It turns out that these differences exist and the whole “root of evil” is found in them. I came across this video. In it, the author describes well the design of the rear locks and makes a VERY important remark that easily explains what the difference is and why the rear doors are so difficult to open.
And so the whole essence of the problem is that in the rear doors, behind the place of traction, they simply made a bracket on which the handle lever rubs. And at this moment the main effort arises, because The silumin hook of the handle moves very tightly on the metal platform of the lock bracket. At first I didn’t even believe it, but when I removed the handle and pressed the lock lever with my finger on the closed door, I was very surprised at how easily the door opened. As I found out later, AVTOVAZ also knew very well about this and supposedly even corrected this ailment with new grants, this is written about in detail here. And so we see: a rod has finally been installed on the rear doors
I haven’t yet figured out how best to remake the mechanism, so I just sanded the surfaces of the bracket and handle hook, and then lubricated everything well. By the way, the handle itself had a very tight movement, i.e. when it is already removed from the door it is still not easy to open. Accordingly, I cleaned it and lubricated it in the same way, and it became much better. The effect of what was done turned out to be higher than expected, so my doors have not opened even once in 3 years of operation. But it turned out to be so simple.
Way out
What to do if the car door does not open from the inside or outside? In fact, there are not so many solutions.
- Call a qualified service technician to open the door or lock. Considering current prices, just one call will cost the owner half the average salary. So it's not fun for everyone. This service can only be used in extreme situations;
- Remove the door hinges and unscrew the lock fastening: this option is more suitable when the front doors are jammed. The bottom line is this: if the door cannot be opened either from the outside or from the inside, then you need to use a Phillips screwdriver to unscrew the two hinges of the rear door that follows the “problem” door. In this way we will provide access to the rear wall of the lock mount. Here it’s a matter of chance, you can unscrew two bolts the first time, or spend 10-15 minutes doing this. After unscrewing the bolts, disconnect the rear wall of the door lock from the body. All that remains is to make an effort to pull back the door, and everything is ready;
- Next, it is necessary to remove the mechanism itself and do diagnostics, look for the cause, but this is “a completely different story”;
- Unscrew the rubber seals and get to the lock hook: the solution to the situation is very good, both for the domestic and foreign automobile industry. No matter which door is jammed, you need to remove the upper rubber seal between the glass and the outside of the door. Before us will be a space one centimeter wide, which must be used with maximum efficiency. The idea is to find a piece of wire, bend it at the end, creating a kind of small hook.
- Lower it into the space created in the area of the door lock, and pull the hook from the inside. I’ll say right away that the task is not easy and requires half an hour of practice. As a rule, you can open the lock 10-15 times. And then the standard procedure for finding the cause.
What to do if the rear doors are jammed?
Depending on the design of the car, try to reach from the luggage compartment side to the lock mounting with a Phillips screwdriver. In this case, the longer the screwdriver handle, the better. Be prepared for the fact that you will have to completely immerse yourself in the trunk and carry out work.
There are known cases of VAZ and GAZ vehicles being opened, but there are no cases of foreign cars. The procedure will take more than an hour. It is easier to get to the mount in a car with a station wagon or hatchback, since the distance is minimal, and therefore in the field of view, unlike a sedan.
Warning
Use this feature carefully! If your outside handle breaks, you can only open the door by removing the door trim. This is very difficult to do with the door closed.
This is the bracket, but on a poorly adjusted lock it already works poorly (about the designer of this lock, it’s right on point. He’s 33 years old and 3 days old) That is. you need adjustment for the minimum pressure of doors on rubber bands (for this you can: move the bracket, use a mallet to crush the top of the rubber bands, bend the door frame (slamming a stack of newspapers on the door) - all methods are good) + correct operation of the handle (photo below), but just don’t saw tooth (you can get the effect of random opening on bumps).
This is it on the removed lock. But if you bend it (removing the play), then it does not bend correctly (you can see this in the 1st photo) - you need to somehow bend its lever itself, and not bend the plane of the stop.

Signaling issues
The “root” of door blocking is often the incorrect operation of the alarm system. The key fob probably didn't work. This may happen due to low batteries. You can try changing the batteries on the remote control if the driver's door in a vehicle does not open. This could be a software glitch. In this case, sometimes emergency mode helps. Does the indicator indicate open doors? The right path to the service station is that the doors are broken.
Refinement of the castle
The method is used by experienced drivers who prefer to repair any fault themselves. This is a makeshift option, but it helps to adjust the smooth running for a year and a half and get a tight fit.
If you grind off a large sheet of metal, then the door may not close.
thermal insulation paint for wall insulation
Craftsmen recommend systematically checking the seals and the external position of the hinges; in this case, door adjustment on Grant will be required less than once a year.

Failed Hacking Attempt
Amateur thieves who decide to steal a car and fail to deal with the lock leave behind a lot of problems for the motorist. The first step when the driver's door does not open is to inspect the lock structure. When using only the key fob to open the doors, you can block them to avoid a repetition of the unpleasant incident in the future. The locks can be fixed; there is no need to change them - this will add additional costs. What else could lead to a depressing situation?
Adjusting Lada Granta locks
If the previous adjustments did not help solve the problem, you can try to fix it by adjusting the lock striker.
Tools required for work:
Work order:
It may also happen that after adjusting the lock, the door closes easily, but is not in the same plane with the surface of the body - it can protrude above it or be recessed relative to the body. If a protrusion appears, do the following:
If the part is recessed, then it should be pulled out:
Seat belt problems
Sometimes it doesn’t even occur to you why the driver’s door does not open, and the reason may be trivial: the seat was not fully retracted. An oversight made by the owner of the vehicle himself leads to a sad event. The door structure is blocked from the inside. When placing the belt over the locking mechanism, there is a risk of jamming the entire system.
If the driver's door does not open from the inside, to free yourself from “car captivity” you need to push the seat belt away from the inside of the car. It must be inserted while simultaneously pulling the door handle. In this case, it seems that the driver is trying to open the door, but when the belt is removed, it will begin to function perfectly.
About mechanical problems
A case where the driver's door closes and does not open, although you can safely exit through the passenger seats, indicates the appearance of mechanical defects within the structure. Common “illnesses” include broken rods and broken cables synchronizing the handles. It is impossible to do without dismantling the panel from the inner surface of the door system and without the experience of a locksmith.
Why is the door trim removed?
Most often, the trim of the rear or front doors is dismantled in order to get to the internal cavities where the window lift mechanisms are installed. Although during the entire period of operation of the car there are other situations when it is necessary to remove the trim:
- for installing acoustic speakers built into door cards;
- in case of failure of the electric window lift buttons;
- for dismantling glass for the purpose of tinting or replacement;
- to repair or lubricate window lift mechanisms;
- to replace facing panels that have become worn or scratched over the years of use of the machine.
Front door cards Lada Kalina
It is also necessary to remove the trim during body work, when it is necessary to weld rotten elements, renew the car’s paintwork, or carry out anti-corrosion treatment.
Note. Many motorists remove the upholstery to make additional vibration and sound insulation of the body themselves.

Algorithm of actions in case of jamming with central locking
Most often, the driver's door with central locking does not open on frosty days. The following problem is observed: the levers on the key fob open, you can only enter from the passenger side, or all the doors except the driver's open. It happens, on the contrary, all the doors are jammed, the driver's door can be opened with the key. All this could be a sign of a blown fuse: its electrical circuit stops working. In such a situation, there can be a huge number of reasons for this, including faulty wiring, broken wires; a specialist will be able to accurately determine them after diagnosis. It is worth calling a specialist to unlock it. What advice can you give to a car owner?
- From time to time it is necessary to open the doors with a key. This will help prevent the cylinder from sticking and will keep the locking mechanism in working order.
- There is no need to try to warm the locks using a hairdryer or boiling water.
All doors are locked
If it is impossible to get inside, you have to act decisively; the damage will be calculated later. An effective method is using two wooden rulers or thin metal plates. If the driver's door does not open, the reasons can be varied, and in the absence of time to find an answer to this question, drastic measures have to be taken: rulers must be inserted into the crack between the seal and the roof. You will need a wire that needs to be bent to form a loop at the end. She pushes herself inside the cabin. The task of the loop is to hook the button and pull it towards you. Didn't give in? Calling a specialist is the only option. How else can you get to the steering wheel?

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.
Another tactic
If a person is far from a service station, and there is no opportunity to invite a specialist, it is recommended to try such manipulations.
- If there are problems with the front doors, you will need to remove the door hinges and unscrew the lock fasteners. A square screwdriver enters the “battle” with a jammed lock. It will help to unscrew the two hinges of the rear door, located behind the front door in one row. The measure helps to get to the lock fastening. The two bolts are disconnected and the locking mechanism wall is removed. All that remains is to pull back the door structure.
- For interior work you will need the same tool. You can remove the door trim, handles, remove the electrical wiring for now and lift the glass. This way provides access to the lock. Again, a wire with a loop at the end will come in handy. You need to get to the “heart” of the device and pull the hook. It is better to use a flashlight to carry out the procedure efficiently.
How to prevent such situations?
"Forewarned is forearmed!"
To prevent difficulties, do not forget about timely lubrication of the locking elements. Fasteners and hinges require close attention. Children should not be allowed to hang on the doors or lean on the body themselves: this leads to their deformation. The slightest misalignment can cause the locking device to jam.
Blocking is caused by poor-quality drying during the washing process, or a sharp decrease in air temperature after the heat. We advise you to constantly monitor the condition of the seals, wipe them from condensation in rain or snowstorms. You can prevent condensation from forming by not immediately closing the doors before leaving the “swallow” in the cold: the advice is to keep them open for a while. It is highly not recommended to use a lighter to “freeze” locks. A good alternative option is a keychain-defrost, a special anti-freeze spray.
Rubber gaskets must be lubricated with silicone grease containing water-repellent substances. Thanks to this technique, a film coating is formed that serves as good protection. In winter, it is better not to leave the “steel horse” in the cold; the best solution would be to use a heated parking lot.
Currently, many car enthusiasts are asking the question: why doesn’t the driver’s door open (despite efforts) on a new or not so Priora? It is worth noting in this regard that all problems mainly arise from the fault of the central locking. The situation is aggravated by the fact that the owners simply do not find the necessary information.
The main signs of a malfunction in the locking system installed by the manufacturer on Priora are as follows:
- the door does not close;
- does not open;
- unlocks on its own.
Moreover, car enthusiasts often complain that it is impossible to open the lock with a key, from a key fob or from the inside.
In reality, in about 90 cases out of a hundred, the culprit of the malfunction is the lock installed directly inside the driver's door.
Preparation for dismantling
To unscrew the fasteners and remove the door trim, you need to prepare a simple set of tools:
- screwdriver with cross slots;
- long flat screwdriver;
- a pointed tool, such as an awl.
Door disassembly tool
Since the door card of the Lada Kalina car is held on by plastic fasteners (otherwise known as clips, pistons), there is a warning regarding the working conditions. It is strictly not recommended to dismantle door trim in the cold, when the plastic becomes brittle and easily destroyed. Hence, there is a risk of breaking all the clips during the process of removing the decorative panel. Therefore, in winter, perform this operation in a heated garage or box.
In the summer, there are no requirements for premises; remove the casing even in the open air. There is only one recommendation: in windy weather it is better to drive the car into the garage, otherwise a lot of dust will be brought into the interior when the doors are open.
This is what the door card lock looks like
Advice. In cars that are 5 years old or more, the plastic from which the retainers are made dries out and becomes brittle. When separating the trim from the door of such a car, you will probably ruin some of the clips. So it’s worth buying new ones in advance, there are 8 pieces in the front door, and 10 pieces in the back door.
Device
The weakest point of the Priora locking system is the microswitch. The electrical package itself, used on the model in question, is a rather complex device. It is his responsibility to receive the owner’s command to unlock or lock the door. Having received a certain signal, it activates certain electrical networks that supply the drive. In this case, the electrical package can perceive orders in two ways at once:
In the first case, having sensed the order to close, the immobilizer turns off the alarm and energizes the electric drive of the lock, closing or, conversely, opening the contact groups of the microswitch.
Then the latter, all the time the lock is locked, monitors whether an order has been received to open the doors.
Why is everything arranged this way? Everything is simple, because the command in this situation can be received not only from the key fob, but also from the switch if the car owner used the key. This allows the immobilizer, when the security alarm is activated, after detecting a raised blocker, to immediately begin to act according to the alarm protocol.
So, the biggest problem of the Priora is water getting inside the door. As a result, the contact groups of the microswitch quickly oxidize and become overgrown with verdigris, similar to moss. The volume of the working surface increases significantly and the contacts stick together. In addition, the oxides have fairly good conductivity. As a result, the passing tension is perceived as an order to unlock or lock the doors.
It is possible to get rid of such a malfunction only after replacing the blocker, or the microswitch itself.
Other most common problems and ways to eliminate them are described below.
The door does not open in cold weather
Most often this happens after washing a car or driving in the rain, when dampness gives way to negative temperatures. Usually the larva freezes completely in the lock. Sometimes the lubricant in the drive or rod also hardens.
Knowledgeable car owners advise warming up the constipation (for example, with a hairdryer) and then lubricating it with WD-40. Moreover, the procedure must be repeated after each significant wetness of the car.
In addition, it will also help:
- turning on autostart with constant heating of the interior;
- disassembling the door and adjusting the lock components;
- use any silicone-based lubricant.
If the door does not open with the key fob
First of all, you should make sure that the button itself is working. The battery often runs out.
Further, if the indication goes off after using the key fob, then most likely the wires leading to the lock installed directly in the door have simply frayed.
This, in particular, is also indicated by non-working window regulators.
In such a situation, you will have to disassemble the door (that is, remove the trim from it) and check the integrity of the chains. It will also be necessary to inspect the fuses - they usually blow out from the slightest overload, and their damage leads to failure of the locking system.
Another common factor is a poorly charged battery, because it is from it that all systems installed on the car are powered. In cold weather, as you know, the battery discharges the most. Moreover, if the battery is disconnected for a while, then the immobilizer often starts to work incorrectly.
Sometimes mechanical problems can interfere with opening, but in this case the door cannot be unlocked with anything.

| 1. | Vasily: after two years of active use of the car, there are no complaints about the body or its elements. The doors close easily and the locks are also in good working order. I try to treat equipment with care and carry out diagnostics in a timely manner. |
| 2. | Kirill: at 65,000 km I adjusted the hinge once on the right side. Obviously there was a bad fixation from the factory. There are no more complaints, I am satisfied with the build quality of the domestic car. |
| 3. | Ivan: for the first time, a Russian car turned out great. Of course, there are complaints about the technology, but they are insignificant. Those who are familiar with a screwdriver can easily eliminate defects on their own. |
| 4. | Gennady: I haven’t noticed anything like this in a year and a half of driving. All mechanisms are operating normally, lubricated and secured. |
| 5. | Dmitry: after buying the car, I immediately re-tightened all the moving elements myself, lubricated them additionally, and adjusted the gaps. I haven't had any worries for more than a year. |
| 6. | Alexander: I bought the car two years ago from a dealership, drove more than 80,000 km, no comments. There were minor breakdowns, but I fixed them myself. There were no major breakdowns. |
| 7. | Ignat: in a year and a half of active operation of the machine, I adjusted the hinges twice and lubricated them additionally. In general, there were no serious breakdowns. |
| Negative | |
| 1. | Kirill: I’ve only driven 75,000 km, but I’ve already adjusted the hinges, changed the seals, and ordered soundproofing for the interior. |
| 2. | Gennady: the dashboard is systematically fastened on the paving stones, I can’t do anything. I contacted specialists and repaired it myself, but it didn’t help. |
| 3. | Vladlen: there are more shortcomings in Grant than advantages; the manufacturer is in no hurry to eliminate defects. |
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.
We replace the body element ourselves. At the preparatory stage, we check the availability of tools, lubricants, and rags.
The average service life of the locking mechanism is 120–150 thousand km.
