What is a car central locking system?
The central locking system allows all the doors on a car to lock at the same time. Nowadays, most cars are fitted with a central locking system. All the driver needs to do to make the function come to life is push a button on the key fob or a switch in the car to lock or unlock all the doors simultaneously and automatically.
The idea of the central locking system is to give a driver greater control over all the doors via a simple switch or button. The central lock can come into play in the followings ways:
A mechanical key
Moving the internal door handle to an opening position
Pressing operating buttons on a radio remote control
When you use a remove button, the control will send a signal to the door lock relay. This lock relay then activates the lock actuator in the door, causing the lock to open and grant you access to the vehicle. When a key fob is used, it sends a signal to the engine control unit to kick up the system’s functions. If your central locking system is faulty, a specialist can help to diagnose and fix the problem.

Which central locking repair service do you need?
There are several parts involved in the operation of a central locking system, which is why a diagnosis is often required to find the exact fault. Often, central locking systems are supplied as complete units, so repair can be difficult if the unit itself is problematic, in which case a replacement will be needed.
Here are some of the problems that can arise in a central locking system and the services that can repair them:
Blown central locking fuse
If one door works as it’s meant to, but another door doesn’t, it could be something as simple as a blown fuse. The good news is that fuse replacements are not expensive and are easy to replace, so a good place to start with diagnostics is to check the fuse.
If the locks on all doors have suddenly stopped working or responding, then the problem could be the key fob. The battery may have died or something could be preventing the fob from sending a signal; in this case, it might need replacing.
Broken door lock solenoid
If one door lock is being problematic then it could be the lock solenoid. In a central locking system, the solenoid in each door will activate the lock or unlock function.
Broken or damaged electrical wires
If you are finding the locks are working intermittently and of their own accord then it could be due to broken wires or a faulty connection. This will cause intermittent power from the key fob to operate the locks.
