Hi Steve, Mmmmmh... I've had this before on a Micra and another Nissan, and they both showed codes starting 14? but I don't remember what precisely! I know I couldn't find any precise info on codes for the immobiliser. The last one I did the LED seemed to suggest the key had read OK, but the garage did say that the key had to be recoded (I think). Sorry can't be of further help. Regards, Nick Bell
