Bought a k12 a few weeks ago.......keyless entry. Thought I'd try the emergency key access in the passenger door. Prised the plastic cover off...... key went in fine and turns freely left and right....... trouble is nothing happens and the door stays locked. Tried the search on here but no joy I'm afraid unless I've missed it. Any idea what the problem could be or does it need a Nissan dealer? Any advise/help would be much appreciated. Geoff
