Hi guys

i have a k12 I need to sync immo and ecu. It has I-key so uses a 12 digit pin for immo and keys which I have. However when I try to do c/u initialization, it won't let me enter a 12 digit pin, it wants a 4 digit.

Tried x431 to, asking for 4 digit pin.

does it have a 4 digit pin for immo sync and 12 digit for keys? Can a 4 digit be made from 12, or is software not right??

thanks
