It was working fine, and now the central locking has stopped working completely. I cannot lock my car at all. Using the actual key I can lock the drivers side from the outside, that's it, the passenger side and the boot stay unlocked. Whilst in the car, the button to lock all doors doesn't work either. The fuel cap was locked completely, but
SOURCE: Central Locking does not work. You must reset your remote control in order for the lock/unlock to work properly. To reset remote you would: 1)Insert Key in Ignition Turn to Position 1 (Don't Start the Engine) for about 5 seconds. 2)Turn Key Off and HOLD the LOCK button on Remote while pressing the UNLOCK 3 TIMES.
If the fuse is not blown, they will try to repair the car's central locking system. If the car's central locking system is beyond repair, they will replace it with a new one. 2. Inspect the Door Lock Actuators. Most newer cars have a central locking system that locks and unlocks all the doors with the push of a button.
