Central locking Lada Granta: installation and troubleshooting

The alarm is very useful and multifunctional. With its help, you can protect your car from thieves or accidental collisions in the parking lot. More complex security systems are capable of using a key fob to open the trunk from a distance, start the engine, or perform a host of other interesting functions.

Lada Granta models such as Norma and Standard do not have an anti-theft system in their factory equipment. The factory simply does not install them, since the designers considered this part superfluous, if you do not take the immobilizer into account.

That is why this article was created, since the relevance of the issue of installing an alarm system on the Lada Granta is soaring at exorbitant heights. Despite the fact that there is a huge range of security systems for cars on the market, they have almost identical installation schemes, with only minor differences.

Review of the standard central lock Grants

Before studying the principles of operation of the central lock, it is necessary to understand its composition. Such a system consists of the following elements:

1. Central locking control unit.
2. Door limit switches.
3. Interior lighting.
4. Actuators – horn and door locks.
5. Remote control.

We will try to understand each element separately and analyze how the central locking on the Lada Granta works.

The principle of operation of the central locking system on Grant

The central link in this system is the control unit. It is he who processes all signals and issues “instructions” to actuators. The control unit sends impulses to the door locks and locks them.

Also, on command, it reverses the polarity on the locks and unlocks them. Limit switches are used to control the status of doors (open or closed).

The central locking unit needs this information to turn on the interior lighting and prevent the locks from locking with the door open to avoid damage to the drive or rods.

A remote control is used to control the central locking unit. It has three buttons:

1. Opening.
2. Closing.
3. Opening the trunk.

To close the machine, you need to press “close”, to open it, press “open”. The trunk can be unlocked even if the car is armed.

To do this, hold down the button on the remote control for a few seconds - the trunk latch will be unlocked, and the trunk lid will not be taken into account. The lid must be closed within 30 seconds or an alarm will sound.

Any opening of the door while the system is armed is accompanied by a horn tone and the hazard warning light blinking. Thus, the car attracts attention in case of unauthorized access to the interior.

Additional features

It is worth noting that the system can be controlled not only using the remote control, but also the corresponding key on the driver's door. By pressing this key, you can lock or unlock all the doors of the car.

This is convenient in case of a sudden attack by intruders or to protect children.

The Central Lock Grants provide the ability to automatically lock the doors when the vehicle is moving.

To do this, this function must be activated:

1. Start the engine.
2. Press the open and close button for 5 seconds.
3. A beep will sound under the dashboard as confirmation.

Now, when you reach a speed of 20-40 km/h, the car doors will lock automatically. This will eliminate the possibility of a child opening the door at speed.

Another possibility is power window control. If you hold down the door lock button on the remote control for 3 seconds, the central locking unit will raise all the windows in the car - very convenient if someone forgot to close their window and the ignition was already turned off.

The unlock button works the same way – it opens windows.

Programming the duration of control pulses

Even if the alarm is connected correctly, it is not a fact that the owner will be able to control the locks from the key fob. The point is that it is necessary to correctly select the duration of the control pulse (for locking and opening). Do not make it too large to avoid overheating the actuators.

See what exactly the manufacturer Starline offers. We can set the pulse duration to 0.7s, which should be enough. The value “3.6” will be redundant.

The “Lux” package has the following property: after 15 minutes of inactivity, the electronics “fall asleep”. It may take an extra push to wake her up. So, try using the option where there is a double impulse. The main thing is not to activate the “comfort” option, which uses a duration of 30 seconds. To connect an alarm system with “Comfort”, you need to install an additional unit in “Grant” (AvtoVAZ does not produce it). We wish you success.

Malfunctions of central locking Lada Grants and solutions

The central locking is designed to ensure the safety of the car from intruders, but in order to maintain its functionality, it is necessary to promptly identify and eliminate malfunctions. Problems can be different and each has its own solution.

Fault table:

This is a small, but the main part of the malfunctions that can occur with a car central locking system.

Is it possible to install central locking on Lada Granta

There are Grants configurations (below Norma), where central locking is completely absent. Car owners who are accustomed to comfort are probably wondering whether it is possible to install a central locking system with a remote control on this equipment?

It is possible, but doing this with original kits is time-consuming, expensive and impractical.

The best solution is considered to be the immediate installation of an alarm system or a universal central locking system. Regardless of the path chosen, the steps will be the same. First, let's figure out what you need for basic installation:

1. Control block.
2. Drives for door locking.
3. Limit switches.

Lada Grana is equipped with limit switches mounted in the body. Therefore, there will be no problems with their installation and there will be no need to buy an assembled lock, as on foreign cars.

After purchasing everything you need, all that remains is to do the following:

1. Disassemble all the doors and install in each of them an electric drive connected to the lock rod.
2. Lay the wires in the rubber corrugation of the door and connect them in parallel at one point in the cabin - where the control unit will be.
3. Do the same with the door stops. Connect the wires to the central locking system according to the diagram, connect the control unit to power and test the operation of the door locks and limit switches. If everything is ok, move on to the next step.
4. Connect the alarm part of the central locking system to the standard horn.
5. Hide the control unit far inside the car. Preferably, under the dashboard - as much as possible, where only you can reach.
6. Assemble the doors and all other parts of the interior.

Such a central locking system will differ from the standard one, but may have a lot of additional functions. For example, the Start-Stop button, which is very popular, as well as its own original control panel.

INSTALLATION

Installation of the structure begins with removing the trim from each door. But before that you need to disconnect all the terminals from the batteries. This will allow you to install the system without risk of electric shock. The following steps follow:

1. Remove the panels.
2. Select a location for installation. The best place is considered to be the lower left corner. Otherwise, there is a risk that the glass will interfere with the operation of the locks.
3. Install activators for the central locking.
4. Connect the rods and activators and secure the clamps. It is very important to check the wiring when connecting each device.
5. Pull the wires. Use plastic clamps to secure them.
6. Remove the dashboard. The same needs to be done with the old wires responsible for the operation of the power windows. Route new cables and connect them.
7. Connect the drives and insulate them.
8. Push the wires into the dashboard and glove compartment.
9. Install the through pipe.
10. Attach a fuse to the connector. This element must be connected to a common power supply. The resulting structure is mounted under the torpedo.
11. Connect the central locking system to the car. The minus goes to the body, and the plus is connected to the fuse.

After this, the installation of the central lock can be considered complete, as you can see, there is nothing complicated about it. It is not surprising that most drivers decide to do it themselves.

IMPORTANT NUANCES

When installing a central lock with your own hands, there are certain nuances that will help you do the job at the highest level. Here are the main ones:

• It is best to use a corrugated tube for pulling wires.
• Do not run wires along the bottom of the doors. This may cause a short circuit.
• To achieve better accuracy, the rod can be bent.

Just three recommendations will allow you to avoid common mistakes when installing a central lock with your own hands.

How to replace the central locking control unit on Grant

The central locking unit on a Grant rarely fails, but if it breaks down it can cause a lot of trouble, for example, spontaneous opening or closing of doors, even if the car is just parked in the parking lot.

The central locking unit is located behind the fuse mounting block. To get to it, you need to:

1. Remove the trim panel of the mounting block under the steering column.
2. Remove the block from the mount and move it to the side.
3. Unscrew the two fastenings of the standard alarm system.
4. Disconnect the electrical connector.
5. Remove the central locking unit and install a new one in its place.
6. Reassemble in reverse order.

To avoid mistakes, you should know the article number of the new control unit - 21900651201000.

Installation

Installing an alarm system on a Lada Granta with your own hands consists of several stages:

1. Removing the plastic steering column lining. Then the instrument panel is removed and the map mounted on the driver's door is removed. The parts are secured with screws and plastic plugs, which are removed with a special mounting spatula.
2. The installation location of the main unit depends on the dimensions and characteristics of the product. Small modules of Starline or Pandora products are located behind the dashboard.
3. Route the control diode to the front pillar trim on the driver's side. The antenna unit (in some assemblies contains an impact detection sensor) is glued to the top edge of the windshield. If the owner has previously installed the unit in a different location on the glass, it is recommended to replace the layer of double-sided tape that was glued to the module body at the factory.
4. The siren sound signal is installed in the engine compartment, the cable is routed into the passenger compartment through standard channels received in the engine panel. Since overheating of the housing damages the electronics of the unit, the exhaust manifold provides protection from the sound signal. The base of the siren is fixed with screws that are screwed into pre-drilled holes.
5. When installing an autostart alarm, it is necessary to install a sensor that measures the temperature of the cylinder block. The device is fixed with a nut according to the manufacturer’s recommendations; do not squeeze the element when installing.

Installation Rules

An alarm installation map (separate for each device model) is included with the factory installation instructions. During installation work, the elements are securely fastened with self-tapping screws or plastic clamps. When using double-sided tape, the adhesive layer may be destroyed due to temperature changes, loose parts may be damaged, and the vehicle's standard electrical wiring may also be destroyed.
