A few days ago my central locking refused to unlock the doors, I have fitted an Rclick unit which has worked perfectly. The unit was still flashing the indicators so I have assumed that this is not the problem. When I tried to unlock the drivers door with the key nothing happened, so I had to open the passenger door and unlock the drivers door from inside. Yesterday I discovered that if I unlocked the boot, then the drivers door would work with the key. Any ideas?
