My 2003 V35 key couldnt be cloned by any locksmith without the BCM code, believe me they tried and then referred me to nissan aus
My guy craked the BCM immobiliser code in 2 minutes, it saved me through to japan to get BCM pin number,
Foget nissan australia, they charge to much
My guy supplied me with 3 new chips which he programmed and now i have the original key plus two more spare
This guy can do V35, V36, any nissan skyline, ring him.......
