Hello

I would like to make extra key (second) for f25 pre lci 2012.
Oryginal key is comfort acces 868 HUF5661
What would be the best way to add key? Will obd function work?
I have bought same number used key and going to clear it HUF5661
When i unlock cas via obd will first key work?

Hello

i already unlock cas4+ viaobd.
I made a key using old unlocked key from f20 (huf5661).

I made two differentkeys and i have a problem, because keys which i made do not work as oryginal one.
Orginal one working fine( unlocking, comfort aces), while on made keys only coil work, and any buttons and comfort acces dont.
What should i do? Should i buy china keys?

Both keys which i use are identical numbers as mine oryginal, but they are from f20 and f30? could that be a problem, because of fem?
Thanks.
