It was 16 years ago, and I only worked with what got to the US. I don't remember much and not those at all. I saw a few how to program key fob documents but we decided that was a dealer service and so I never implemented it. still generally just send the right 4-8 bytes and press a button on the fob in a minute. In any case it sounds like you want a different end: making a fob or bypassing them was never something I got anything on.
