Reasons for replacing the VAZ 2114 lock cylinder

The mechanism is silent, but if an extraneous sound appears when opening the door element, the device will have to be dismantled or rebuilt. Replacing the front door lock cylinder on a VAZ 2114 is required for a number of reasons:

• a sharp drop in temperature;
• failure of the locking ring;
• loss of the fixing column;
• destruction of the plastic rod cap;
• wear of internal pins and teeth.

In winter, the locking devices freeze, causing the key to turn with difficulty or not move. If a person makes an effort, then there is a risk of breaking the opening element in the core of the lock.

When individual parts wear out, they will cling to each other, blocking the rotation function. The main factor indicating a repair is turning the key.

Causes of malfunction

Before replacing a part, you should find out the cause of the failure. The main ones:

• damage after an accident;
• mechanical damage to internal elements;
• Hacking attempt;
• failure of the external door opening manipulator;
• pressing hard on the handle.

Most often, the plastic part breaks or breaks as a result of constant opening.

Recommendations

Reassembling and lubricating individual parts will not work if the fragments are heavily worn. It is better to remove the cylinder from the core and install a new one. Recommendations for replacing the VAZ 2114 door lock:

1. Partial repairs or lubrication will only temporarily restore life to the closing mechanism. If problems arise, it is better to replace the entire cylinder.
2. After installation, it is necessary to periodically lubricate the mechanism. Experienced motorists use silicone substances for this.
3. The repair procedure is carried out in a well-lit room at a comfortable temperature.
4. To change the element, you will need a set of screwdrivers, pliers and lubricant.
5. Sometimes the springs have to be replaced along with the cylinder. They are purchased separately.

The cylinder fragment is sold as a set. The price depends on the manufacturer. If you buy a cheap Chinese version, it will cost about 150 rubles. It is better to give preference to VAZ spare parts. The cost of such a kit is 400-500 rubles.

Withdrawal procedure

Depending on the reason, a complete or partial replacement is performed. It is not recommended for the average person to engage in reassembly, since there are too many nuances in this process, but almost anyone can replace the mechanism. Step-by-step instruction:

1. Three screws are unscrewed. They are located on the inside of the handle. To do this, use a Phillips screwdriver to remove the cover.
2. The front trigger glass position switch is removed along with the wiring harness block. To do this, the wires are first disconnected.
3. The plug on the armrest handle is removed, the element is picked up with a thin corner of a screwdriver.
4. Unscrew the 2 screws on the handle that hold the inner panel.
5. The plastic clips are pressed out to remove the lining.
6. 6 pistons are removed to remove the door card.
7. The external fastenings are removed, the nuts are unscrewed with an 8mm wrench.

The last action is to gain access to cravings.

How to remove cravings

To remove this piece, you will need an impact screwdriver and a size 8 wrench. The piece is attached to the internal locking mechanism and the lock switch. Algorithm of actions:

1. The internal lock of the outer handle rod is completely disconnected.
2. The handle is removed along with the rods.
3. The pin is removed from the end of the rods.
4. The plastic tip is removed from the core of the cylinder device.
5. The return spring is removed. The old larva is being removed.

Usually the rods are fixed with plastic hinges, so they can be disconnected with a flat-head screwdriver.

Installing a new part

The removal and assembly algorithm is the same, although the instructions for installing the cylinder mechanism have its own nuances. Before inserting a new cylinder into the core, the part is lubricated with a silicone substance and only then inserted into the handle. Further algorithm of actions:

1. The return spring is inserted next to the cylinder.
2. The functionality of the key is checked. It should turn easily in all positions.
3. A pin is installed on the tip of the rotary rod. Connection is being made.
4. The inner and outer panels are screwed on, the handles are fixed, and the plug is returned to its place.
5. The main three screws are tightened from the inside.

You won’t have to change the lock cylinder for a long time if you carefully use the opening mechanism.

Replacing the inner handle

If the internal door handle of a VAZ 2114 is broken, then cosmetic repairs are impossible. To repair, you will need a standard set of tools: several types of screwdrivers, a sharp knife and a 8mm wrench. It is better to change the part while in the salon. Algorithm for replacing a part:

1. The lining is removed. It is pryed off with the thin end of a screwdriver. It is important to remove all fragments of decor.
2. The door card is being dismantled.
3. The rod is disconnected.
4. To remove the remains of the broken opening device, the fasteners are unscrewed.
5. A new element is installed. It should be attached to the rod, and then the facing elements should be reassembled.

The trim on the VAZ is fixed with special clips. To remove them, you can pry up the edge with a screwdriver. Proceed with caution as they are plastic and may break. This is affected by rough handling, material wear or cold.

Step-by-step replacement of the lock cylinder on a VAZ 2114

Let's say the key in the VAZ-2109 lock does not turn or, conversely, turns and does not unlock the door. Repairing car locks involves one of the following actions: replacing the cylinder (cylinder), replacing or repairing the internal lock. In official manuals, by the way, it is recommended not to repair the internal lock mechanism, but to replace it. Be that as it may, you first need to get to it, for which you remove the door trim. Each of the actions required for dismantling is further illustrated in the photo. The entire sequence must be considered in order.

Door lock device

Theoretically, the lock mechanism can be divided into 3 parts: a handle with a cylinder and a button, the main mechanism, and the inner door handle. All nodes and connections between them are shown in the diagram.

Door lock mechanism VAZ-2109

The node labeled “2” looks like this.

Internal mechanism (not collapsible)

4 rods fit to it, that is, to this node. Two of them are connected to the external handle, and in order to dismantle it, the rods are disconnected.

If there is no electrical wiring inside the door, you do not need to disconnect the battery before performing repairs.

In other cases, that is, when power windows or locks are installed, the battery must be disconnected. To do this, as many people know, it is enough to remove the “negative” terminal. This means that before repairing locks, the hood is opened first, not the doors. Anyone who violates such a requirement will, at best, have to change burnt fuses.

Replacing the door lock cylinder

To gain access to the locking mechanism, you need to remove the trim. On the “Nine” it is quite simple to remove it - the casing is held in place by plastic pistons. These pistons are located around the perimeter; they are simply pressed out and, if necessary, replaced with new ones.

Performing dismantling of the main part

First, as is easy to understand, you need to dismantle three elements: the side handle, the window lifter handle, the socket of the inner handle of the lock. The “dog” must be pulled up, but it is better to remove the seal that protects the glass during the dismantling of the casing.

Removing and disassembling the door handle

When the door trim is missing, you can freely disconnect the two rods that go from the door handle to the lock. The following shows exactly what elements we are talking about.

Wire rods “handle-lock”

By squeezing the plastic tab with a screwdriver, the rod is disengaged. We will assume that all of the above actions have been completed. Then, you can move on to the next stage.

The outer handle is attached to the metal using two nuts. One of them is located under the trim, the second is on the back side of the door. Both nuts need to be unscrewed.

Attaching the outer handle assembly

After dismantling the specified unit, it will be easy to remove the cylinder. This is done like this:

1. Push out the pin holding the outer plastic cap;
2. Dismantle the mounting spring (see figure);
3. By installing the key and turning it, the cylinder is pulled out.

The appearance of the spring holding the cylinder and the handle together is shown below.

The round spring is completely dismantled

It is important to know that the knot itself, called the “larva,” needs careful handling.

Experience shows that it will be easy to lose the metal pins that ensure secrecy. The cylinder is secured inside the handle body and the pins remain in place. But if you pull the cylinder out, each pin is “free.”

Replacing and adjusting the trunk lock

The work is carried out in the following order:

1. The casing is removed.
2. Replace the support mechanism. If the lock's supporting tooth breaks. Replace not only the cylinder, but also the new body. In general, this work is no different from what needs to be done to repair a door lock.
3. Adjustment is carried out using the lower clamp. Unscrew the nuts and remove the washers. Assembling and disassembling the lock will help you adjust the lock. In this case, you need to act using the selection method. The desired result is the moment when the door closes effortlessly and does not vibrate when slamming and driving the car.

More extensive work is required if the retainer bushing is broken. If you are changing the lock assembly, then before its fasteners are fully tightened, you need to adjust the latch. Only after the lock closes perfectly can you tighten the fastening nuts to the maximum.
