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.

Features of the Chevrolet Niva door The rear 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. 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. It is enough to perform a few simple steps: To do this, you need to pick it up with a screwdriver and pull the latch.

You can now unlock the door by pulling the actuator or rod. You can also use a long screwdriver to move the lock latch. 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. What parts and components fail most quickly on a Chevrolet Niva?

How to open a car without a key?

Fan-avto All my life I have been surrounded by cars! First, in the village, already in the first grade, I was rushing around on a tractor through the fields, then there was JAVA, then a penny.

Now I am a third-year student at the Polytechnic Faculty of Automotive Engineering. I work part-time as a car mechanic and help repair cars for all my friends. If there is a problem such as spontaneous closing of the doors, then most likely the central locking drive and rod, or the lock gear have become unusable, and in order to replace them, you will have to dismantle the door trim.

And besides this, it protects from extraneous noise.

The procedure for dismantling the door trim 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 trim, you must follow the following procedure: In total, there are eight fixing bolts on one Niva Chevrolet door, and some of them are hidden behind decorative plugs.

Unlocking the lock.

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.

What to do if the door in a Chevrolet Niva does not open.

There is only one way out in this situation - dismantling the door card, aligning the rods, dismantling, lubricating and cleaning the lock. Moreover, the sooner you do this, the less likely you are to end up with a completely blocked rear door.

Design features, or a tricky spring A jammed trunk lock does not open the door of a Chevrolet Niva Niva Chevrolet There are no particularly complex mechanisms in the rear door lock on a Chevrolet Niva. The lock is ordinary, it works according to the VAZ principle, the only difference is that it is locked and unlocked by an actuator. Actuators also fail, but this happens extremely rarely. And even in this case, it is always possible to open or close the door manually.

However, this system also has nuances - if you activate the central locking with any door open at least one click, the door lock of both the rear door and any other door may not open. Tricky spring. Therefore, if you have it left in the cabin, and the door is locked, then there is no other way out than 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 order. A way to open a door without a key The following two tabs change content below. About the expert: Fan-avto All my life, the door of Chevrolet Niva cars has not opened for me! Smooth roads and working mikriks to everyone. I left the keys in the car and it locked.

My solution to the problem In general, I have one set of keys for my Chevrolet Niva and sooner or later this was bound to happen. I left my jacket in the back seat while I changed clothes for fishing, and the keys were in my pocket.

The wind blew, the door of the Chevrolet Niva did not open and slammed shut, then I heard a click - the alarm went off and the car closed. The windows and trunk are closed.

Why the back door of the Niva Chevrolet does not open

That’s it, we’ve arrived, I thought. You grab the metal rod with strong pliers and forcefully pull it up, then open and disassemble the door, that’s it.

Don’t be afraid to pull, there’s nothing special there to break, but replace the electric motor immediately after disassembly, most likely it’s this. Breaking out the rod couldn’t be easier, my motor was jammed so that it was not easy to pull out the rod with a screwdriver, even by applying force directly to the rod.

Open using a ruler

First, let's look at a method that always works with cars from a domestic manufacturer. To do this, we need a simple stationery tool that every schoolchild and every home has - a ruler. First, you simply pull out the seal near the closed lock and insert an iron ruler there. You need to apply good pressure with this ruler, and then the flag will definitely rise up. This trick will not work with newer cars from foreign manufacturers, since special protection was installed against it, but with the Niva you can still try.

What could be the reason that the door does not open?

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. In winter, the door may freeze to the body due to the formation of condensation on the seal or moisture ingress after washing. But these cases are not a breakdown and go away on their own over time.

Correct installation

Install the immobilizer in the following order:

De-energize the vehicle's on-board network by disconnecting the corresponding battery terminal.
Installing the device on the steering column is considered a reliable option. To do this, the elements of the plastic panels are removed and a mounting location is selected that is remote from moving mechanisms.
The central control unit is installed. The method of fixing it should prevent the transmission of vibrations to the block during travel, otherwise the block will quickly break. The placement of the block must be hidden. For example, in factory wiring harnesses.
The wiring that comes with the device is laid. The wires are connected to the control unit, to the ignition switch and other auxiliary systems according to the diagram developed by the device manufacturer.
According to the same scheme, the blocking relay and sensors are installed.
An LED indicator is placed inside the cabin in an open or disguised manner. Open installation of the indicator in some cases can scare away a potential thief. A hidden installation can confuse an attacker and force him to look for the blocker, and then disable it.
Finally, the device is programmed and trained according to the immobilizer manufacturer's instructions.

The driver's door on a Niva Chevrolet does not open, what should I do?

Door lock mechanism close up.

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.

A way to open a door without a key

If there is a problem such as spontaneous closing of the doors, then most likely the central locking drive and rod, or the lock gear have become unusable, and in order to replace them, you will have to dismantle the door trim.

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.

What are the doors of the Chevrolet Niva made of?

The Chevrolet Niva is a 5-door SUV, with 4 doors designed to accommodate passengers and the driver, and a fifth to open access to the trunk. They all have the same principle of operation, which is to press the handle and open it for landing. They consist of a metal base, glass, canopies, handle and lock. These are the main details, but there are also auxiliary ones, which include:

A handle or electric button for raising and lowering the glass.
Window lift mechanism.
Mirrors placed on the outside of the door.
Internal handle for closure.
Sheathing. Can be plastic, fabric, leather or leather substitute.
Internal locking lock.
Front door pocket. It is designed to store a first aid kit and cleaning supplies.

Latest models of the Pulls contain holes in the front doors for installing speakers. Many craftsmen install speakers completely freely and without first maintaining a place for them.

How to remove trim from Shnivy door

There are many reasons for removing the casing. This can be either replacing the window lift mechanism, lubricating the mechanism parts, quieting the door, installing speakers, replacing the handle or its mechanism, the lock cylinder, and more. Therefore, cases often arise when it is necessary to remove the casing and carry out repairs or maintenance, and some drivers, for the purpose of modernization, change the old casing to a new one. To remove the casing, you must perform the following sequence of actions:

Take the necessary tool in the form of flat and Phillips screwdrivers and a knife.
Pry out the plastic plug on the handle and remove the armrest handle.
At the bottom there are 3 screws that secure the pocket. The screws are unscrewed with a Phillips screwdriver and the pocket is removed.
Having pressed the opening handle, the screw is unscrewed with a screwdriver. The opening handle is not removed along with the trim, so you should not try to pull it or tear it off.
The cladding is removed by passing the handle under the cladding. Then we control the door lock lever; you need to lift the trim up so that the lever remains in place.
The cladding has been removed and the necessary repairs are being made.

Features of the door design

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.

What could be the reason that the door does not open?

How to disable and why

Disabling the immobilizer is necessary in the following cases:

if it breaks and blocks the operation of the power unit;
if there are problems in the operation of one of the elements of the anti-theft device;
if one of the wires is severely or partially damaged and this damage interferes with the transmission of signals;
if the car owner decides to install another immobilizing device;
if you need to equip your car with an anti-theft alarm.

Jumper

To disable the immobilizer on a Chevrolet Niva yourself, prepare a wire jumper in advance. It is necessary to restore information exchange between the engine control unit and the diagnostic output when the immobilizer is disabled.

To clear the memory, disconnect the power from the blocker control unit. After this, install a jumper between contacts numbered 9 and 18, closing them. Then, instead of a standard chip, a specialized chip is installed, containing software for clearing the blocker’s memory.

Place the ignition key in the lock and turn on the ignition for 3-5 seconds so that the blocker independently clears its memory and reflashes itself.

It should be noted that this method is only suitable for those vehicles that have a Bosch M1.5.4 electronic engine control unit installed. On cars with a VS.1 or January 5.1 block, re-soldering of the chips or the use of third-party software is required. On machines with a Bosch MP7 block, it is necessary to unsolder the microcircuit and separately flash it.

Code shutdown

The coded disabling method can only be used if the contractor knows the special password for the immobilizer.

To clear the immobilizer code yourself, you need working and training ignition keys. The working key must have a black head, the training key must have a black head with a red insert.
Close all doors. Insert the training key into the ignition switch, turn the ignition on for a few seconds and turn it off immediately. The LED indicator should begin to blink rapidly.
As soon as the LED starts blinking, within 6 seconds remove the training key and insert the working key. Turn the ignition back on for a few seconds. The immobilizer control module should emit 3 beeps.
Without turning off the ignition, wait for the beepper to sound twice again. After this, the immobilizer will turn off. Do not turn off the ignition.
Without turning off the ignition, wait first for a triple sound, and after a while for a double sound signal from the buzzer. After this, turn off the ignition and insert the training key into the lock instead of the working key.
After installing the training key, a single beep should sound and the LED indicator lamp should begin to blink quickly.
Within 6 seconds, turn on the ignition with the learning key. The Check Engine light should turn on on the instrument panel, and after another minute it should go out.
Enter a password consisting of numbers from 1 to 9. To enter each number, you must press the gas pedal all the way as many times as the number shows. After each press, fix the lower position of the pedal for 3 seconds. If the number of presses corresponds to the password number, the Check Engine will turn on on the instrument panel.
If the number is entered correctly, the Check Engine should go out within 5 seconds after turning on. If it does not go out within this time, the number was entered incorrectly. If the LED indicator starts blinking even faster, it means the password was entered incorrectly.
To re-enter the password, turn off the ignition and turn it on again with the learning key.
To exit the code mode, turn off the ignition.

What to do if the rod is broken or bent

Typically, the rod breaks when the mechanism is heavily contaminated. If after cleaning the surface the problem is not resolved, then more serious measures will be required. When the rod is bent or broken, it must be replaced. Straightening the product does not always bring the desired result. Operation of the device will resume, but the repaired fragment will limit the movement of closing or unlocking the door. It is better to completely replace the element.

After removal and installation, it is important to check the functionality, and only then assemble the device.

Purpose of window lifters

Almost all Niva Chevrolet cars have special electric motors in their front doors that automatically raise or lower the windows. The control buttons are located directly on the doors on the driver's side and on the passenger's side. The rear windows are lowered and raised exclusively manually. Perhaps in the future we will see an updated Chevrolet Niva model, which will be equipped with an electric window lift system, but for now we have what we have.

Tips for motorists

Such a malfunction is “not fatal” for the car, but very unpleasant. Unfortunately, this problem occurs on this model. The problem can be either serious or not so serious, which you can easily fix yourself. That's what we'll talk about in this article. Malfunctions can be in the mechanical part, as well as in the electrical equipment of this system.
