Replacing the door lock cylinder viburnum

Removing the lock and replacing the cylinder

The design of the trunk lock on the Lada Kalina consists of two parts: the cylinder where the key is inserted and the door locking mechanism itself. All this is disconnected separately and will be written about this in more detail below.

If you need to replace the larva, it is quite easy to remove it. You can do this using an 8mm socket and a flathead screwdriver. Below is shown which bolts need to be unscrewed to release this part along with the body.

Now that the bolts are unscrewed, take a plastic screwdriver and use it to pry off the plastic retainer that secures the rod to the body of the cylinder. For clarity, below is a photograph that clearly shows what needs to be done:

Then, carefully take the larva so that its spring, which is located inside, does not jump out. If you need to replace a part, then replace it with a new one and assemble everything in the reverse order.
If it is necessary to completely remove the entire mechanism, then you will have to do a little more work. We unscrew the door locking mechanism itself with a large Phillips screwdriver, there are only two bolts:

When everything is done, you need to pull it a little towards yourself and it can be easily removed; all that remains is to disconnect the plug with the power wires from this structure:

That's all the repairs, which will take about half an hour if you have the right tools and this manual. We install all the removed parts, which can be bought at absolutely any auto store, in the reverse order. I hope that I helped someone with this photo report using the example of my Lada Kalina station wagon.

Today we will talk about such an important car system as the ignition system. Serving as a power control mechanism and responsible for starting the engine, the ignition is at the same time subject to quite serious breakdowns. We will talk about how to recognize a malfunction and how to fix it in this article.

Design of VAZ-2109 locks and disadvantages

The lock cylinder is a cylinder that is equipped with a secret mechanism. In all locks with a flat key, the cylinder is replaceable. For example, on VAZ-2109 cars it is replaced like this.

The rotating part that is connected to the rod is called the “drive”. As we can see, this drive has a hole for removing the cylinder. By applying pressure with a thin axle or an awl, the larva is pulled out.

There is only one drawback - it is hardly possible to complete the steps indicated here without first removing the lock completely.

It should be noted that even when the mechanism is removed, it will not be easy to pull the larva out of it.

Therefore, before dismantling, be sure to insert a key into the cylinder and turn it left or right 90 degrees. The purpose of this action is to be able to dismantle the larva. This action is performed effortlessly, and the key is then simply pulled towards you.

Egnition lock

The ignition switch is a complex device designed to control the supply of power to vehicle systems, prevent battery discharge and ensure that the engine starts from the starter system. The castle includes two components:

mechanical, represented by a lock cylinder;
electrical, which is a set of contacts that close electrical impulses when the key is turned in one way or another.

The ignition switch on the Lada Kalina has three modes:

Mode "0". In this position, the key can be easily removed, and the lighting, emergency lights, and audio system work.
Mode "1", fixed. It is no longer possible to remove the key from this position; when it turns on, the ignition system is turned on and power is supplied to all systems except the starter. But it is worth considering that keeping the key in mode “1” for a long time can lead to battery discharge. This position is used when turning on the starter, so that the running fuel pump pumps up the required pressure to ensure further ideal operation of the starter.
Mode “2”—activation of the starter system.

The Lada Kalina ignition switch kit contains a key for the lock, which serves not only in its straight profile, but also as a key for the doors and trunk.

Features of standard locks

Getting to know the car begins with opening the doors. The first impression can be spoiled by careless adjustments, the use of low-quality materials or imperfect design. The entire Lada Kalina family (sedan, station wagon and hatchback) to one degree or another has these disadvantages. These disadvantages appear even with slight wear of parts, especially the rear doors of the car.

On modifications of the new generation of Kalina, including the “Lux” package, silent locks are installed. Instead of a metal locking device, they use wear-resistant plastics, which significantly improve the operation of the mechanism and provide more comfortable operation. But complaints about poor adjustment of moving body parts persisted in relation to new models. Car owners are also unhappy with the difficulty of opening the rear doors.

Ignition switch malfunctions

Like any electronic device, the ignition switch of the Lada Kalina is subject to frequent breakdowns. Malfunctions can occur for a variety of reasons, the most common of which are the following.

Oxidation of contacts always leads to serious damage (usually due to moisture and dampness in the machine)
Contact burnout , which occurs due to sudden voltage surges. Voltage drops usually occur when the power unit is started, during which the temperature inside the system rises sharply, causing the insulation to simply burn out. This is why it is so important to approach the launch issue wisely.
Mechanical damage . If, when you are about to turn the key, you notice that it has become more difficult to do so than usual, it means that something happened to the lock cylinder, perhaps it was simply clogged with dirt or dust, or maybe there was a defect at the factory that came to light only now.

If the problem lies in burnout or oxidation, then when you turn the key in the lock, you will not see any reaction from the ignition system. In this case, you just need to replace the contacts without changing the entire lock; if the defect in the wires is not severe, then you can get by with cleaning the contacts.

Damage to the lock cylinder also occurs when someone tries to steal a car. In any case, the lock needs to be changed completely. But how to do it yourself?

Replacing the ignition switch yourself

Unfortunately, the Lada Kalina cannot please you with its reliability and durability; many systems, including the ignition switch, fail within a couple of years, so in order to save on repairs at expensive car repair shops, it is better to find out how to do it yourself. So, having come to the conclusion that the lock needs to be changed, we buy a new lock, which costs around a thousand rubles. In the kit we will receive three cylinders (on the doors and trunk) and 2 keys. You also need to purchase four shear bolts , since the old ones will no longer be suitable after dismantling.

How to remove the lock and replace the cylinder

To gain access to the trunk lock of the Kalina sedan, it is necessary to dismantle the internal plastic trim. It is held on by two bolts, which makes it easy to remove. They are located in the places where the handle is installed, in the so-called latching pistons. You can pry them off using an ordinary screwdriver.

The design of the trunk lock of the Kalina hatchback consists of two parts. This is the larva and the mechanism itself responsible for blocking the door. Elements must be disconnected individually. Below you will find information about such deletion.

If you need to replace the larva, everything can be done in a couple of movements. All you need is a deep socket and a flathead screwdriver. Then you should unscrew the bolts and release the desired part of the housing. When the work is done, you need to use a plastic screwdriver to remove the clamp, which is attached to the body of the larva. Next, it is carefully removed, holding the spring. Then the replacement is made, but in the reverse order.

Replacing a trunk lock or disassembling the entire mechanism requires a lot of effort. You need to unscrew the door lock using a screwdriver. There are only two bolts, so the job is quick. You can remove the mechanism using a Phillips screwdriver. When everything is done, just pull the lock and it will come out easily.

To summarize, it is necessary to note what tools are needed for the job. These include:

plastic screwdriver;
deep head;
Phillips screwdriver.

The work is not at all difficult, the main thing is to purchase an electric trunk lock and perform all the steps described.

Instructions for replacing the lock

You can replace the lock on Kalina's door yourself using standard tools. To do this, you need to remove the trim and disconnect the fixing bracket. Then you need to dismantle the door opening handle by unscrewing three screws and removing the lock switch rod. Now you need to unscrew the lock fastenings and push the mechanism inside. While holding it, remove the switch button rod. Once you have access to the desired assembly, pull out the latch and disconnect the electrical wiring harness connector.

In case it becomes necessary to replace the wire connector block with its body.

After freeing the lock from mechanical and electrical contacts, you can remove it. The standard locking mechanism is a non-separable design, so if it breaks, it should be replaced with a new one.

Door locks prevent unauthorized entry into the vehicle. Along with the requirements for operational reliability, they must provide comfortable operating conditions: easy to close and open without creating unnecessary noise. Most malfunctions or irritations can be resolved independently using the recommendations provided.

Electric drive: easy installation option

The technique is simple, the only thing you need is to make a rotating plate and a rod for it yourself. The wiring should be routed to the electric lock and connected to a special control unit. When disarming the car, the electric trunk lock will be activated after the fifth door opening button is unlocked.

The entire installation task is based on connecting the electric lock to two wires. You can purchase the part at any auto store. The trunk end must be additionally hidden to prevent water from getting into it. Otherwise, it will periodically short out during rain. An important attribute is the trunk hinges. Wires are often broken in this place, so their condition must be carefully monitored.

Before installing the electric drive, the trunk lid trim is removed. The main thing is not to damage it during this process. It is recommended to choose a lock that will not need to be modified during operation.

An important step in the installation process is wiring; you can use those wires that are standardly suitable for the fifth door of the car.

Power is taken from the cigarette lighter. An important point is the installation of a protective fuse. The wire is laid along the threshold; it will take approximately 3.5 meters. Then the installation takes place.

It is advisable to choose an option that does not require drilling additional holes. The procedure consists of connecting the wires according to the diagram. Important: you can use the wire that goes to the trunk light.

Installing an electric drive is not difficult, but for the first time it is a labor-intensive process. If difficulties arise, you can seek help from a service station.

In order to gain access to the rear door (trunk) lock, you first need to remove the inner plastic trim, which is attached to two bolts at the handle attachment points and latch pins, which are pryed off with a flat screwdriver and removed.

In order to successfully replace the trunk lock in a domestic car Lada Kalina in a sedan, station wagon and even a hatchback, you will need to stock up on some tools and accessories. The algorithm of actions is simple, so such work is available to owners subject to responsible preparation.

Instructions for replacing the lock

Dismantling requires preliminary preparation. It is important to take care of the room in which the work will be carried out; it is better to choose a well-lit place with a comfortable temperature. A closing fragment or larva is purchased. The necessary equipment is prepared:

screwdrivers;
pliers;
socket wrench 8;
Silicone Grease;
knife.

Only disassembly will show how to repair the object. If the pins break, the core changes. If mechanical damage occurs, the entire device is replaced.

Replacing the larva in Kalina

To change the element, you will have to disassemble the door card; this is the only way to get to the lock and remove the trim. To replace the cylindrical core you must:

Unscrew the handle that is held in place by two screws.
Remove the trim panel.
Disconnect the speakers, disconnect the power window wires.
Unscrew the block with the wires; to do this, press the clamps.
Unscrew the fastening of the intermediate link arm.
Remove the rod; to do this, turn the screwdriver around its axis.
Pull out the end of the clamp.
Remove the plastic cap.
Remove the lock cylinder.
Carry out lubrication work or install a new device.

The parts are assembled in the reverse order. If difficulties arise, it is recommended to contact a repair shop.

How to dismantle the lock to replace the cylinder?

You can gain access to the lock mechanism by removing the plastic upholstery inside the luggage compartment. This protective component is fixed by means of two bolts, which are located in the places where the special handle is installed. They are also called latch caps. They are pryed off with an ordinary screwdriver.

Structurally, the trunk lock in the Lada Kalina is made of two parts, regardless of the body type, hatchback, station wagon or sedan. They are presented in the form of a cylinder and the unlocking mechanism itself. If it is necessary to replace the trunk lock, then the dismantling of these components is carried out in a separate order.

When you only need to replace the larva, this can be done in a few simple steps. Here you will need a screwdriver and a socket.

By unscrewing the bolts, we release the necessary part of the body.
Next, remove the retainer using a screwdriver. It is attached directly to the body of the larva itself.
It is recommended to remove it very carefully, while holding the spring.
Installation of a new element is carried out strictly according to the reverse manipulation algorithm.

If there is a need to replace the lock itself, the operation becomes a little more complicated due to the need for additional actions.

First, the door lock is unscrewed using a screwdriver. This is not difficult since the element is held in place with only two screws.
Now we pull the trunk lock outward, and it freely comes out of the landing niche.

As you can see, removing the trunk lock is not difficult.

Replacing the larva in Kalina

First of all, replacing the lock elements means that the door trim will be completely missing. Therefore, first we will figure out how to dismantle the trim on Lada Kalina cars. The second chapter is devoted to how to remove the larva and install a new one in its place. The last step will actually be the simplest.

Removing the door trim yourself

The casing is attached not only to screws, but also to plastic pistons. The number of screws holding the part in question is four:

Numbers here indicate all fastening elements. But to get to them, you need to remove the screw cap “3”, as well as the inner door handle. The pawl handle also needs to be unscrewed.

If these actions are completed successfully, the casing begins to be dismantled, moving it away from the metal. Dismantling is carried out starting from any of the corners, but care must be taken: the pistons holding the plastic are fragile.

If the package includes power windows, you will need to disconnect the connector connected to the button block. Also, another similar connector is present in most trim levels - where there is a central lock. Both connectors must be disconnected.

All the steps described here involve electronics in any case.

Therefore, at the stage before dismantling the trim, you need to open the hood, take the “10” key and unscrew the negative terminal. We are talking about the battery terminal, which can be connected last (when the last screw is screwed in). Anyone who breaks this rule will look for blown fuses. Draw a conclusion.

How to get to the door mechanism

According to the recommendation of the magazine "Behind the Wheel", in the absence of casing, access to the lock is always available. Simply put, there will be no need to remove the inner lining made of metal. The steel sheet is simply bent to the side.

The rotating part with the protrusion is called the “drive”, and this is what you will need next.

Replacing the larva will be easy:

The key in the cylinder currently fixed in the door is turned 90 degrees;
Using a steel ruler, knife or thin screwdriver, you need to press the locking tongue located opposite the slot in the body of the cylinder. You need to place a screwdriver between the rotating and stationary parts of the mechanism. Know that in the driver's door the slot is made from the bottom (looks “to the floor”), in the passenger doors - from the top!
By pulling the key towards you, the larva is pulled out;
The new cylinder is installed like this: with the key inserted, it is pushed into the lock until it stops. The locking tab will need to be pushed inward.

How is the activator installed?

The only way to get inside the trunk of a Lada Kalina is this manipulation - turn the key and press the button. This action is not always associated with convenience. For example, in bad weather or when your hands are full, this is not easy to do. This circumstance prompts owners to consider purchasing and installing an activator. Installing this useful element is quite simple. Here you will need a self-tapping screw, which will secure the device we are considering. To check the functionality of the activator, you should connect it with the standard connector from the on-board network.

After the current supply to the activator is stopped, the door is locked with the first latch, but remains not completely closed. To get back inside the luggage compartment you will need to use the key.

Installing a push-button lock is not a very difficult task. To implement it, you will need to assemble a circuit, which requires wiring. Here you will need to “attract” the programmable channel present in the alarm.

You can connect the device using two options.

We connect the button with the positive output of the activator (12 V), bypassing the relay. The advantage of this scheme is the absence of unnecessary components and simple connection. As a negative aspect, it should be noted the need to lay additional wire lines.
The second method is more labor-intensive. Here you will need to use additional components (diodes). You also need to find the ground connection point. The main advantage is the need for a minimum number of wire lines.

Experts prefer the first method because it is simpler. For switching, you can use copper wire type PV-3, the cross-section of which is 1 mm2. Laying should be done on the left side along the thresholds. You can connect by means of a clamp and subsequent wrapping with electrical tape.

The control wire of the activator may be a standard red-pink cable. It is subject to commutation with the relay, followed by winding the contact and placing it under the BUS fixation frame. The entire list of manipulations is performed with the battery disconnected.

How to install the activator

The only way for the viburnum to get into the trunk is to turn the key and press the button. Naturally, doing this is not always convenient. Weather, busy hands and other troubles contribute. At this stage, many car enthusiasts begin to think about the trunk activator. It is quite possible to do this, you just need to try a little.

The Kalina station wagon trunk lock activator is easy to install. It is enough to take a self-drilling screw and secure it on one side with it and on the other with a wire holder. To check the device, you need to connect it to the standard connector.

The only problem in all this work may be the back door being picked up at the wrong time. After the current stops supplying the activator, it closes with the first latch, but the trunk is not completely closed. In order to get into the so-called fifth door, you will have to use the key again.

A lock with a button is not difficult. But during work it is necessary to assemble the circuit and stretch the wires. In this case, one programmable alarm channel (additional) should be used.

There are two main connection options. First: the button goes to +12 on the activator, bypassing the relay. The advantage of this connection is its simplicity and the absence of unnecessary elements, the disadvantage is the need to run additional wires.

Installing the activator using the second method is more labor-intensive. You will have to use additional elements, namely diodes. In addition, there is a need to search for “mass”. The main advantage is the use of a minimum number of wires.

Electric drive: easy installation

The manipulation algorithm is very simple. Here you will need to make the rotary plate together with the rod yourself. The wiring is laid directly to the lock and connected to a special control unit. When the car is “disarmed”, the electric drive of the luggage lock is activated following the unlocking of the button responsible for opening the rear door of the Lada Kalina.

The whole essence of the action comes down to connecting the electric lock to two cable lines. You can buy the product at a specialized retail outlet. The end of the luggage compartment will need to be hidden in order to prevent the risk of moisture getting into it. If this is neglected, then with the penetration of water a short circuit will be observed in the designated area.

Much attention should be paid to the area near the door hinges, because broken wires are a common occurrence here. To prevent this, it is recommended to regularly monitor this section of the highway.

Before starting the procedure for installing the electric drive in a Lada Kalina car, you will need to remove the plastic trim. Here you need to be careful not to damage the specified protective element.

The choice of a lock for LADA Kalina should mean that there is no subsequent need for modifications before installation. This means drilling additional holes.

An important point in the installation procedure is the laying of electrical lines. For these purposes, you will need about 3.5 m of appropriate cable. You can use standard wiring suitable for the rear door. The power source can be a cigarette lighter socket. It is also important to install the fuse correctly.

We do all switching in LADA Kalina in accordance with the diagram.

Important! The main line in this version may include a wire that goes to the courtesy lamp for lighting the space inside the trunk.
