Central locking problem

[vernons01]

I am having trouble with unlocking the doors via the key but occasionally it does open. The doors will unlock all of the time as well as the boot so have to manually open the doors with the key. Has anyone experienced this or does anyone know how to fix this. Cheers. Andy
