Hi folks, since the cold weather has kicked in (freezing outside!), My key won't turn in the driver's lock to lock the doors (it works to unlock though). Still works in boot lock to lock/unlock central locking. Don't want to try to force the key incase i break something. The remote locking has never worked since i've had the car so I currently rely on these. Any thoughts? Maybe mechanism has tightened up in the cold? (my old e36 BM used to do this in winter), or some microswitch bother?, any help welcome before i go pulling the door panel apart!
