So, about a year ago, my lock switch from the internal of my key broke off the main board, disaster! Anyway low and behold it has now happened to my second key, obviously I must be pressing it like the hulk or something! I managed to get two used keys from a breaker mate, have replaced the board, blade and immobiliser internals with mine so the car still starts etc however I cannot reprogram the new fob for remote locking as none of my originals work to allow me to start the programming sequence. Has anyone any suggestions as Nissan quoted me almost £270 a key! Couple of helpful guys on here have offered me some possible send away options, but just wondering if anyone has any diy ideas?
