Got a 318i SE (E46) and unfortunately we only have one key (not uncommon - only have one with the ST200).
Anyhow, the key has a mashed "Lock" button and there is a seperate BMW fo (but no blade in it) which we use to lock/unlock the car.
First question is: Can we get a replacement second key, and if so where from/how much?
Second Question is: If we press "Unlock" once, the car unlocks but the drivers window goes down. If we press it twice, the ar unlocks and the windows stay up. Is there a way to fix this?
