If your central locking is not working, there are a few things you can do to try and fix the problem.
First, check the fuse box to see if the fuse for the central locking system has blown. If it has, replace it with a new fuse and see if that fixes the problem.
If the fuse is not the problem, then it could be an issue with the central locking system itself. If this is the case, you will need to take your car to a mechanic or car dealership to have them take a look at it.
There are a few other things that could be causing your central locking system to not work, but these are the most common. If you are still having trouble, it is best to consult with a professional to get to the bottom of the problem.
