Hi,
i disconnected my battery (under bonnet) whilst i fed some wires through from my radio to my boot. Upon reattaching battery everything appeared fine.
My alarm which is aftermarket, locks and opens my car no problem, however the next day, after arriving home, with my windows and sunroof open, i decided to look cool and close them all at once with my key, as i sometimes do.
I put the key in, turned 15 degrees to the left, and nothing., not a sausage. nada.
upon further examination, the doors will not close using the key. but will with alarm. from inside the car, each door will lock on its own, but not together as it ought to.
took it to the local BMW dealer and they tried an alternate central locking brain, nothing. no difference.
did all the usual window and roof resets, and everything in the car works perfectly as it ought to, apart from the key in the door locks.
any ideas as this is even stumping the bmw people.
cheers
Chris
