My central locking is not working, the drivers door key half turns but not enough for the door to unlock (I can get in through passenger door thankfully) but because I cant unlock the drivers door I can not open it to remove the interior panelling any suggestions
See if you can pull the rubber strips out each side of the window to try to get a piece of wire in and pull the lever up. Might be worth a squirt of WD40 into the lock.
I had this problem a few weeks ago - most likely is a little spring has snapped on the lock mechanism.
I managed to bull back the door card enough to get my hand in and release the lock manually, then open the door and replace the spring with the one from the passenger side.
