Thread: Electric lock not working

Have a 1997 Disco the remote locking has not been working for awhile.But have been able to lock with key in drivers door.Sunday went to lock and nothing happened with the key.Am able to lock by pushing button down and holding handle open shutting drivers door.Have checked fuse and is okay.My throughts are the actuator is dead but which one and any ideas on how to test.

I dont know much about discos but generally with central locking:
the master lock actuator on the drivers door controls all the other door locks, so start there.

On most cars the master actuator in the drivers door has 4 wires, a 12v +/- feed and two control cables for lock and unlock - these are usually negative trigger so can try disconnecting these wires from the actuator and touch one or other to ground to test lock/unlock your other doors. Also check you are getting the 12v feed (fuse gone?)

A new master actuator is around 12 bucks from jcar so can try replacing it for a start.

Replace the battery in your key fob if you havent done that already!
