People are trying to form life easier, more convenient, and faster because we are becoming busier day by day. Long ago, mechanics invented a mechanism in cars which will significantly reduce the time we unlock and lock our car doors. The system is named car central locking. With this system, the driving force can unlock/lock all the doors at once. Another useful benefit of having a car central locking system is that some systems provide an aware of help drivers locate their cars during a crowded parking lot, which saves drivers plenty of time, especially once they are in a hurry.

What is a car central locking system?

Briefly to mention, a car central locking system controls the access to a vehicle, for example, your car via a foreign control. Helping drivers to lock and unlock their cars without touching the cars isn’t its only function. Other functions may include opening handles or lifting, braking, and opening the bonnet and trunk. Most manufacturers provide car central locking systems as an optional feature. Generally, a car central locking system must contains electrical parts, door lock actuators, and a foreign control. Other components could also be included are bonnet assembly, trunk assembly, and side entrance assembly.

Security locking system

The most obvious advantage of a central door locking system is that it provides a fast and easy way of locking all the doors of your car together just by operating the driver’s lock. the safety gain is that there’s no danger of leaving a door unlocked. you’ll also easily lock the rear doors to stay young children inside the car.

To convert your car to central door locking you would like a kit, which you’ll readily buy from a car accessory shop. It consists of electrically operated drive units that you simply mount inside the doors, along side all the wiring, brackets and link rods that you simply need for fitting it to your car.

A kit are often used on a two- or four-door car, although the benefits of fitting one to a four-door car are obviously greater. It also can be used on almost any model of car, but you should ask your dealer first just in case your car is unsuitable. it’s also an honest idea to buy around before you buy.

Some kits are also supplied with a remote control. This allows you to lock the car from the outside with a hand-held unit. This has the advantage that, if the locks freeze in cold weather, you may still be able to unlock the door using the remote control.

1. Remove trim

The door trim panels should be removed first to gain access to the within . Remove all the handles and winders before releasing the panel securing clips and lifting the panel away (see Bodywork 8). Carefully remove the condensation sheet fitted behind the trim.

2. Fitting position

Each drive unit should be mounted on the within of the inner door skin so that its own slave rod can join to the link rod between the door locking button and lock assembly. If you’ll , mount it across one of the holes within the skin to form fitting easier. The unit shouldn’t obstruct the glass or opening mechanism.

3. Mark and drill

Offer the mounting bracket to the inner door skin. Mark the position of the screw securing holes with a felt-tipped pen then remove the bracket. Using a drill of an appropriate size, drill out the holes. Secure the bracket with the screws and securing clips provided, fitting the clips behind the door skin.

4. Fit drive unit

Secure the drive unit to the bracket using the screws provided. The screws pass through the mounting bracket and into the 2 holes located within the drive unit body. Route the condensation vent pipe to the bottom of the door and therefore the wiring towards the hinged end of the door able to connect up later.

5. Slave rod

Bend the slave rod into shape. It should run from the drive unit, parallel to part of the existing link rod. Join the slave rod to the drive unit with the clip provided. the 2 rods are connected together with a clamp and screw. Position the rods within the clamp and secure them with the grub screws.

6. Route wiring

A small wiring loom is given the kit to attach the master control unit with the drive units. If possible route the loom beside any existing wiring. If necessary drill small holes within the door and bodywork, fit grommets to them then route the loom wires through the holes into the doors.

Wiring central locking

Each drive unit has a small length of wiring attached thereto which terminates in a multi-plug. The master drive unit is identified by having two extra wires connected thereto . These are the feed and earth return for the whole door lock system. Start by disconnecting the battery to avoid any short circuits . Join the terminal connectors to the ends of all the wires resulting in the drive units.

Remember there are four wires to the master drive unit and only two to the drive units. Connect the wires to the multi-plug terminals ensuring the wiring colours correspond. Route the feed wire to a permanent live feed like the battery terminal or the battery side of the fuse box. Fit an in-line fuse (16 amp) to the present wire. Run the world wire to an appropriate earthing point and secure it firmly. Reconnect the battery terminal and test the lock is functioning correctly. Finally refit the door trim panel and window controls.

Why is your car central locking system not working?

Almost everything has its bad times, so does the central locking system. There are many causes resulting in a broken car central locking system. To narrow down the cases, the most common reasons are listed below:

  • Your automobile battery is dead or it’s malfunctioning: every electrical component needs an influence supplement. Therefore, check your car battery to ascertain if it’s functioning properly or not. Additionally, a dead battery also can cause many problems.
  • The key fob battery is either dead or faulty: the electrical parts of the central locking system isn’t the sole one that needs power, but the key fob does also. Because the battery on the key fob often lasts very long, many drivers may find yourself forgetting its existence. This seems to be one among the foremost common reasons for a car lock to prevent working. during this case, all you’ve got to try to to is replace the key fob battery. However, if changing the battery doesn’t help, the key fob could also be faulty and you ought to contact the dealer for further key fob tests.
  • A blown fuse: While every door works except one door, there could also be a blown fuse. Fuse replacement is that the solution and it’s rock bottom and easy.
  • a nasty solenoid: a nasty solenoid also can cause the previous problem where one door doesn’t work while others do. However, replacing a solenoid costs quite replacing a fuse and it also requires more complicated steps.
  • A broken wire: sometimes, it’s not the battery problems that cause a broken car central locking system, but a faulty wire is.
  • The locks are either stuck or poorly lubricated: this might be a problem also.
