Hi newbie here and first post. I have just collected my Z3 T reg with 1.9 petrol engine. The remote key will lock the doors but not unlock. I just use the key without the remote but occasionally the if I am not careful the remote locks the doors and when I open them with the key and the alarm goes off which can be a bit of a bind at 6am.I have been told that if I get the same type of key ( the three button type ) with all its contents working I can re-programme that key for my car following the instructions from a previous post on here. Can you let me know if that can be done. Thank you.
