I am waiting for getting access to the dump file you placed here. In the mean while, I would like to know what is the data structure of the EEPROM dump. Like where are the RFID transponder codes that encode the actual keys that deactivate the immobilizer (let the car start) ?

What do the other bytes mean - is there like a "reset all keys" section / byte that would allow me to start up a sequence for introducing a set of keys to it ? Like "reprogram the keys yourself" by inserting the keys to the ignition lock one after another, or following a process like that ?

I had to replace my old ECU (and thus the IMMO), so I have now one working key & two "spare" ones from the old that I would like to activate & make life easier... Getting some hard copies of the working key for opening the ignition lock is not the problem, but the now-obsolete naturally transponders are.

Thanks.
