Hello, someone might have a clue which diagnostic device (Amazon, Kaufland, etc.) is naturally able to learn from my 450 Bj keys. Is there something like that? Can this be one of the launch devices from 750 Euro where “Immo Keys” is advertised everywhere, but unfortunately only Merzedes and not Smart is supported? Delphi with laptop and additional hardware is actually too complex to work in. Would you like to just buy, connect, works Thanks for the tips Juergen
