Hi guys
My donor Z3 came with only one key and that did not work the locks with the buttons. I took it to bits and it has been butchered with bits of foil glued in place. It’s obviously not going to work.
Question is do I go to bmw and get ripped off buying two keys with remotes or is there a cheaper aftermarket solution? I quite like the idea of a start button instead of ignition key too.
Any advice ?
Thanks
