Mein Auto: dont
On older BMW's if the battery goes dead, you can unlock the door. It is better to use a non remote key. Turn key to unlock until it stops. Then turn the key some more. When I first ran a crossed this I called the dealer. the service manager said " Turn the key until you think it's going to break, and then keep turning." I'm sure if you get midieval on it, it will break. I have also heard of other ways to supply power to the car, but they didn't sound like something I wanted to try.

I have used this trick on at least 5 BMW's that were deadlocked with dead batteries.

I hope this helps

tatal3nz - that's not hard to do with these cars - I have an odd one that sometimes in parking the car the emergency 4 ways turn on - thankfully I notice as I walk away from the car - but if I didn't I'd have a very flat battery by morning (and you can't jump start an auto - and even if this was the manual - it's too heavy to be pushing around...).
