1996 e36 316, need help badly, last night could not have been a worse night my fob for my car broke we thought it might be the batteries, we got the aa out and they supplied new batteries but it was not the case! the keys that work in my ignition for the car dont open my doors!? and we think the board in the fob has gone, i had to climb through my boot to get into the car and had to drive it home with the alarm screaming i have just detached the live wire from the battery. do i now either get a new fob?, or bypass the alarm and imobaliser? ... HELP!!
