I have a 1998 Seat Ibiza. It has central locking. For years the passenger lock did not work because a child stuffed sand and dirt in it. Now the drivers door key lock will not lock or unlock the doors. I have looked at the problem, it seems the mechanism inside is not functioning. Do you have any suggestions as to what I can do to fix it
From the symptom description, the driver door lock switch is bad or has an open circuit therefore is not activating the central locking system. You would need to remove the door panel to check the circuit.
We do not have any information of your vehicle in our database so is unable to provide you with and schematics of the central locking system.
