#46: Re: New Remote Locking Fob Author: Snoozy206, Location: TelfordPosted: Fri Oct 05, 2012 6:37 am ---- Please, what was the final conclusion?
How can a remote fob transmitter 'know' it has been used on another car?
Programming a new transponder does not know if it is in a remote or non remote key because the transmitter is not active at transponder programming time.
I assume the BSI has to be informed of the remote transmitter by pressing at least one of the rob buttons - hence the BSI remote key synchronisation sequence (which doesn't work for me). Bye the way, that sequence is ambiguous - line 4 says "KEEP the lock button pressed for 10 seconds" but the button has not yet been pressed. It should say "press and HOLD ..." if that is what is intended.
Thanks

I have no explanation but I presume that there are two possibilities:
- the original transponder has some extra info and when the remote synch process is initiated, the transponder is checked for the matching with the fob
- remote board has its own chip which may be used only one time (same as the transponder).
So whatever the answer, after it is coded to one car, it can only be synchronized with the same car, not with another one.
I also have one question.
I found this key: www.ebay.de/itm/180880828342
Does anyone knows for sure (tested, or studied, not only presuming) if the remote fob compatible with the old style fobs (let's say 6554 YR for example) ?
