Thanks fellas, mines a 2002 td4 auto, so it probably doesn't have one, is that right. All my doors locked the other day and my key doesn't work, never has as the linkage from barrel to actuator is snapped. AA man couldn't even undo the handles from the inside with is big long break in hook, ended up smashing a window. Key fob was still making all the right noises, lights flashing etc. Any way got in through window and it starts and drives. Started checking fuses and it was the central locking fuse that had blown, so replace it and it just keeps blowing and doors stil won't open. I think drivers side actuator is jammed as its always been dodgy and thats blowing the fuse. Also i think im right in thinking if drivrs door doesn't de superlock the others wont follow? Any thoughs appreciate cheers.
