Hello dear people, don’t complain, have tried the search and vll. also missed the one or the other. On the topic: I added a Seat LEON as second car and to the vehicle there were 2 keys. One with radio and a normal without radio. Now I would like to have 2 keys with radio. (like also folding keys) Can I buy 1 or 2 keys with electronics 433mhz and ID48 transponders (SOWAS), let it mill and then learn it myself or must one inevitably to Seat or there. Have a key made??? Don’t like to tear down the original keys and take the electronics and the transponder, thank you in advance.
