A central locking system is convenient, it makes things easy, quick and better for everyone be it the driver or passengers. This central automatic system is a perfect car key replacement as with it the driver can lock or unlock all the doors at the same time. You can visualize a central lock as a remote control with which you control access to your car.

Why is the central lock system of your car not working?
Almost everything you use can break down at some point in time and the car locking system is no exception. There are many reasons or causes that can lead to a malfunction in the system. Here are some of the most common ones:
- Your car battery has a problem or is dead. Therefore, as a first step you must check your car battery to ensure it is functioning properly.
- The key fob battery has a fault or is dead. The key fob needs a power source and that is the battery. As the battery lasts quite long, many car owners don’t realize that it exists and can have an issue. In this case, you just need to get the battery replaced.
- If replacing the battery of the key fob does not resolve the problem, there could be a fault in the key fob itself. A professional will be able to help you in that case.
- If except one, all other doors are working fine, there might be a blown fuse. Fuse replacement is the best solution here and is easy and cheap to be done.
- A bad solenoid could also be causing the issue mentioned in the last point, however solenoid replacement is more expensive and complex.
- Sometimes it is not the battery that causes the issue but a broken wire in the system. In that case, an expert will be able to diagnose and fix the issue.
- If the locks are stuck or not lubricated properly, you may again experience issues with the system.
