Try a different key for the same car. Sounds dumb I know but when i locked the keys in stuarts GA we tried n15 keys to open the door and it worked (before stuart killed me)
Yes that was a bit of a revelation; great solution at the same time very disconcerting.
One of the 'older' members might know about this, but when I was looking for a part after joining up a year ago, I found details of discount parts from a member who worked at Nissan somewhere in Kent IIRC. I tried his number and got nothing though - think there might have been some change in his circumstances or summat. Anyone know who I'm thinking of?
