Chevrolet Niva passenger door won't open

Communities › Chevrolet Niva › Blog › The back door does not open(((

Initially, a Chevrolet Niva is equipped with a central lock that can remotely control opening.
For this purpose, each of the 5 doors has a special device - an actuator. It is responsible for removing the lock when receiving a signal from the alarm system. But in practice, most problems with opening the rear door are not at all related to the operation of electronic components.

In 95% of cases the problem is related to mechanical parts. This can be either the lock itself or the rods located inside. In some cases, this may be due to the fact that the Chevrolet Niva door seal freezes on a recently washed car. But in this case it is easy to determine the source of the problem, so further we will consider situations in which the problem mainly arises with the operation of the lock.

Before starting repairs, the door trim on the Niva Chevrolet must be removed. The door card can be removed even after the door is completely locked.

After this, the window lifter handle is removed. To do this, use a flat-head screwdriver to bend it and pull the latch up.
The decorative cover of the handle is removed. It is held on by latches; to disconnect it, you only need to pull it towards yourself with force, after prying it off with a flat-head screwdriver.
The door card itself is held on pistons in the center, top and bottom of the door. They can also be snapped off by prying them off with a screwdriver.

To open a locked door, you need to pull the plastic tongue of the actuator. You can also move the lock latch itself. After it is unlocked, you can remove the lock, but you must disconnect the battery terminals. The lock itself is held in place with screws at the end.

After they are unscrewed, you need to use a screwdriver to disconnect the rods and disconnect the terminals. Then you can pull the lock out of the case. Once it is pulled out, it is much easier to carry out an external inspection to determine the exact cause of the problem. If in doubt, it is better to immediately replace the part with a new one that will definitely be in working order.

Guys, the back door stopped opening. I pull the handle, I'm afraid it will tear it off. What to do, how to open it now. I didn’t freeze, it’s 100% because it’s plus outside.

At the start of production, the Chevrolet Niva was very different from its predecessors. A modern interior, convenient arrangement of instruments on the panel and many other innovations greatly distinguished it and made it more comfortable. But the most important difference was the transformation of the body from a three-door to a five-door.

The Chevrolet Niva is equipped with a central lock, so each door has an additional device - an actuator. It is responsible for blocking the door lock when a signal is received from the central locking system. But in most cases this is not the cause of failure. If the door of a Niva Chevrolet Niva does not open, then in about 85% the problem lies in damage to the rods or lock.

The rod may fail as a result of dirt getting inside the door. Even new cars are susceptible to this. Chevrolet Niva is usually operated in conditions where there are no roads, where there is a high risk of fine dust getting inside the door. But during rain, car wash or wet weather, this dust absorbs moisture and turns into dirt. It can also be bent as a result of improper installation, and subsequent exposure to it leads to its destruction over time.

If you try to force open a jammed door, there is a high chance of bending the rod even more. Eventually, the thrust stroke is greatly reduced and the actuator does not have enough movement to unlock. At the same time, even after straightening the rod, it already changes its length, limiting the stroke.

In this situation, only disassembling the door and replacing the rods with new ones can help. It is important to check the operation of the lock and lubricate it if necessary. If you notice a malfunction in time, it is better to do the work right away, without waiting until the door is completely blocked and more difficulties will arise with its disassembly.

The back door of the car is quite simple. The lock built into it is similar in design to that installed on the VAZ model. If the actuators fail, you can open them manually.

Important features of the system: if you activate the central locking when one of the doors is slightly open, the system may jam, and it will not necessarily be the one that was not closed properly.

This may be a result of the spring jamming in the lock body. This results from the fact that the steel from which it is made may not withstand the operating conditions of the car. As a result, the tendrils of the spring may break off, and the lock will start working after a while. Symptoms, as a rule, can be different, up to the door opening on the move.

Door repair work is quite simple.

First you need to completely remove the decorative trim. This is easy to do even with a locked door. All you need to do is follow a few simple steps:

The screws at the bottom of the door card are unscrewed.
The window lifter handle is removed. To do this, you need to pick it up with a screwdriver and pull the latch.
The screw of the decorative trim is unscrewed.
then you need to carefully release the door card latches. This can be done using a long screwdriver.

You can now unlock the door by pulling the actuator or rod. You can also use a long screwdriver to move the lock latch.

What to do if the rod is broken or bent.

The rod may fail as a result of dirt getting inside the door. Even new cars are susceptible to this. Chevrolet Niva is usually operated in conditions where there are no roads, where there is a high risk of fine dust getting inside the door. But during rain, car wash or wet weather, this dust absorbs moisture and turns into dirt. It can also be bent as a result of improper installation, and subsequent exposure to it leads to its destruction over time.

Diagnostics of the front door lock rod

To figure out how to open a Niva door without a key, it’s worth considering the car’s configuration. The SUV has five opening doors: two front, two rear and a trunk compartment. Euro handles are provided for opening. The structure itself consists of a steel base, glass, canopies and a closing device. Features of auxiliary elements:

There is an electric drive button for raising and lowering the glass.
Inside the door card there is a window lift mechanism, connecting elements made of durable plastic.
There are electronics that allow the rear view mirrors to function and a locking lock.
The covering element is fixed on the decorative panel.
There is also a niche pocket for storing things on the design.

Additional equipment - holes for installing any speaker system. To fix it, the driver cuts out a part of the facing panel, which is identical in size to the speakers. If a person purchases a fully equipped car, then the speakers are already installed in all four doors.

It is known that the locks of all doors and the ignition switch on the Niva Chevrolet are the same. Therefore, if you have it left in the cabin, and the door is locked, then there is no other way out but to break the glass. It is for this reason that it is necessary to maintain the central lock, and specifically the lock in the form of a latch, in working condition.

The screws at the bottom of the door card are unscrewed.
The window lifter handle is removed. To do this, you need to pick it up with a screwdriver and pull the latch.
The screw of the decorative trim is unscrewed.
then you need to carefully release the door card latches. This can be done using a long screwdriver.

Important to remember: Before unlocking, you must disconnect the negative terminal from the battery. After opening, you need to remove the lock. To do this, unscrew the screws at the end...

The Niva comes standard with central locking; each door has an actuator, which is responsible for blocking the mechanical pawl. In addition, the model is equipped with a mechanical locking device.

The Niva's back door, like the others, is connected to the central alarm unit. The door opening process is controlled by an actuator. The equipment removes the lock when receiving a corresponding signal from the car’s security system.

deformation of the lock rod;
a malfunction of the latching pawl mechanism, when the handle turns, but the lock does not open from the inside.

The door lock drive rod on the Niva is a rigid rod made of stainless steel, or less commonly aluminum. The price of the part starts from 700 rubles. The rod is curved in a certain way and serves as an adapter between the door handle and the locking mechanism. The lock may not open for the following reasons:

incorrect assembly after repair or manufacturing defect;
dirt getting into the door cavity.

Incorrect assembly is a rare case, but it still happens sometimes. Dirt in the door cavity can form as a result of the protective polyethylene film peeling off from the frame. First, dust gets inside, and then, mixed with water during car washing or rain, it turns into dirt.

Basically, the rod can bend if it was assembled incorrectly. The problem can also appear if the car is often used in off-road conditions and dirt gets into the cavity. This can happen if the plastic film peels off from the door frame. In this case, dust may accumulate inside it.

During movement, dust settles not only at the bottom of the cavity, but also on all components, including the levers. After the car gets caught in the rain or washed, all the dust turns into dirt, firmly settling on the insides. As it accumulates, it leads to a decrease in the lock stroke, and at the moment when the passenger tries to open the door, great efforts have to be made.

In this situation, complete replacement of the door lock components, or dismantling, lubricating all components and cleaning the lock can help. This must be done as early as possible, even if the slightest problem arises, so that the Niva Chevrolet door handle does not become completely blocked.

The rear door device is quite simple and does not contain complex mechanisms. The lock used is the same as on most AvtoVAZ models. The only difference is that its locking and unlocking is actuated by an actuator. Sometimes they fail and then it becomes necessary to open them manually.

In this case, it is necessary to know the nuances of this system. If you activate the system at the moment when one of the doors is open for at least one click, this can lead to the other one jamming.

In winter, it sometimes happens that after washing the car, water remains in the rubber seals of the doorway, it quickly freezes and prevents it from opening. Car mechanics identify two main failures in the mechanical part of the lock:

deformation of the lock rod;
a malfunction of the latching pawl mechanism, when the handle turns, but the lock does not open from the inside.

Gradually, dirt accumulates and begins to limit the movement of the levers. To open the door, you have to apply more and more force to the handle. This leads to the fact that the rod gradually begins to bend, which transmits this force to the lock levers. And it bends until the actuator has enough movement to unlock the door. In order to troubleshoot the problem, you must:

Remove the rear door trim.
Remove and straighten the rods.
Clean off dirt and lubricate the lock.

I left the keys in the car and it locked. Popados? My solution to the problem

In general, I have one set of keys for my Niva Chevrolet and sooner or later this was bound to happen. I left my jacket in the back seat while I was changing clothes (on a fishing trip), and the keys were in my pocket. The wind blew, the door slammed, then I heard a click - the alarm went off and the car closed. The windows and trunk are closed. That’s it, we’ve arrived, I thought. And let's think about how I can open the car without a key.

The first option is quite logical - call a special service that opens closed cars. So some kind of tricky key that fits all locks. I don’t know the technology, and I don’t need it. The situation is that along with the keys, the phone was left in the car. In fact, I was left on the street practically in my underpants)) Because I changed clothes on the river bank))

Option two is to open the lock using a ruler. Again, I don't have anything on hand. And I don’t know how and can’t even imagine how to open a locked car using a ruler.

Well, it’s good that I remembered the phrase of one person from the reviews of the Chevrolet Niva - everything suited him, so little problems and the phrase - “constantly self-opening rear windows.” Here it is! And I remembered that periodically the rear windows actually opened on their own by 2-3 centimeters.

The fact is that the rear windows on the Chevrolet Niva are manual, and the front windows are electric. Therefore, when shaking, the rear windows gradually open.

And I began to wobble them, slightly moistened my fingers so that they would cling to the glass better (as an option - rubber gloves). Up-down-up-down.

At first the movement was by millimeters, after about 5 minutes I was already able to open the rear window by 1 centimeter. He stuck his fingers there and continued to press down, then lift up with “acceleration”.

As a result, after 15 minutes the window opened by 6-7 centimeters and I was able to stick my hand in and grab the latch with my fingers and pull it up. The car was open and there was no need to break the glass, call the special services and pay them money (according to some sources, they charge from 500 to 1000 or more rubles for opening the car).

I hope my experience will help you. And please do not use it for black purposes.

Tell me, how can I open the door? The central locking works fine, but the door does not open. All rods are intact!

There was such a problem. With the door closed, I somehow bent the trim and opened the door by pulling the rod. I removed the lock device, disassembled it and saw that a small spring had flown out of the groove due to the fact that its tip had broken off. I had to stretch it and bend the new end with pliers, insert it, assemble it - it works!

You open and close with the key, and with the other hand you nervously fiddle with the handle - somewhere somewhere something clings to something, and everything works fine again

Such a nasty thing happened when I pulled the handle without removing the signal. Then it did not open either from the outside or from the inside. After several such dances, a solution was developed: with the central locking open, I slightly open the handle and click the signal to close it. Then I release the handle and open it with a signal. That's it, the door opens. Moreover, this feature only applies to the driver’s door.

Spring failure

Basically, the problem of lock failure lies in the fact that the tendrils of the spring break off, which loads the rear door lock lever. This occurs due to the use of low-quality steel in the production of the part or violations of operating conditions. In any case, such a breakdown leads to the fact that one of the lock levers begins to move in a random direction and it is impossible to predict whether the lock will open at the moment or not.

The lock can jam from the inside if the spring of the traction mechanism, which is responsible for part of the work when opening, is cracked or significantly deformed.

In 30% of breakdowns, the cause of the malfunction is a spring that loads one of its levers. The spring tendrils break off and the lever to which they cling begins to behave completely unpredictably. It is possible that a locked door can unlock and open while moving. The cause of the spring defect: poor, low-quality steel or an incorrectly selected grade of metal. Repairing the mechanism step by step:

Remove the rear door trim.
Check the setting.
Replace the broken spring or reinstall the part if a broken spring is found.

The window is Niva’s weak point

On many automobile forums dedicated to the Niva car, you can read information that their owners are periodically bothered by rear windows that randomly drop down. Of course, they do not open completely, but only a couple of centimeters, but sometimes this is quite enough.

If you delve into the design of the car, you will learn that the front windows are opened using an electric drive, but the rear windows are just the opposite - using a manual drive. This is their main weakness. When the rear windows shake well during a trip, they will definitely open a little.

When the car is just standing, you should constantly rock them up and down. Using similar maneuvers, we open the glass for ten to twenty minutes. During this time, as a rule, you will be able to move the glass down about ten centimeters, and this will allow you to stick your hand into the interior and lift the flag yourself. At this stage, you can finish the review of ways to open a Niva without a key, but we bring to your attention a few more interesting options:

using a tennis ball;
wires;
using a loop of regular rope.

Details about each of these methods

Obviously, you can watch videos on the Internet where professional car enthusiasts perform these procedures, showing everything by their own example. However, it is also worth paying attention to such a moment as what to do so that such situations do not occur at all. After all, it is better that you always have a backup option. Why solve problems if they can be eliminated altogether?

Details about each of these methods

The following will help you avoid such an unpleasant situation:

Spare set of keys. Don’t be lazy, just take it and make a duplicate - it won’t cost you a lot, but the benefits from the duplicate will be enormous. You won't have to worry about losing your keys. This happens to everyone, and no one is protected from losing vigilance for a while, and as a result, the keys.
Decorate your keys with a weighty keychain. It will make them much heavier and you will feel their weight in your pocket. And when you suddenly lose your keys, you will immediately feel it, or even hear them fall on the asphalt, grass, or whatever.
The car key and alarm key fob can also be separated into separate bundles. The likelihood that you will lose both at once is much lower.

It often happens that you simply forget your keys in the car, close the door, it latches, and you go about your business. In this case, we recommend that you simply always be careful and check that you have the keys.

At first glance, it may seem that dismantling the door trim is a rather complicated task, but having sufficient information, it becomes clear that this is not the case, you just need to be quite careful and be careful when carrying out such work.

In order to dismantle the casing, the following procedure must be followed:

In total, there are eight fixation bolts on one Niva Chevrolet door, and some of them are hidden behind decorative plugs.
The presence of all bolts is indicated by arrows.
First of all, it is necessary to dismantle the two plugs that are located at the door handle. It is most convenient to remove them using sharp and thin metal.
When the bolts underneath are unscrewed, remove the two open bolts located directly in the direction of the rack.
We unscrew three more fasteners from the bottom of the doors, they are also not closed by anything.
Lastly, we remove the bolt, which is located under the door handle. To do this, we pull it towards ourselves and unscrew it.
When nothing holds the upholstery, all that remains is to remove it from the “bugs”. To do this, we run a thick screwdriver around the perimeter of the door, pressing the edges a few centimeters, after which the door itself will easily move out of place.

Full size uncoupled Next, use a thin screwdriver to unhook the rod on the door soldier and take it out. We also pay attention to the lock actuator rod (red arrow) - it doesn’t interfere with disassembling, but during reassembly it will need to be put back as it was)

Opening the door

The lock can be unlocked by pulling the plastic tab of the actuator or another lever; using a long screwdriver, you can move the lock latch itself.

When the door has opened, you can remove the lock, but before that you need to remove the negative terminal from the battery. The lock is held on by fastening screws at the end of the door.

Trunk door lock.

After removing them with a long screwdriver, you need to remove the drive rods, disconnect the terminal blocks and remove the lock from the door cavity along with the actuator . After this, when the lock is in hand, the reason will become visible. In extreme cases, the lock can be replaced. Good luck to everyone and obedient locks!
