BMW X3 key doesnt start car but unlocks it
I have a BMW X3 (04) – the key I was using for it was working fine for both unlocking/locking and starting the car. Suddenly that key has stopped working for starting the car, so I am now using my spare key. The problem though is that the spare key doesnt unlock the car (remote).
So now I have to use 1 key to unlock the car and the other key to start it.
Any ideas what I can do?
