Central door locking components - operation, removal and refitting
Note: If a central locking solenoid or motor is to be renewed due to jamming or overheating, the central locking relay must be renewed at the same time even if it is believed to be working correctly. Before starting work on the central locking system, unlock all the doors and the tailgate/boot. Make sure that the keys are outside the vehicle before reconnecting the battery on completion of work.
