I have BMW carsoft 6.5 and it`s very good indeed. You can turn on or off auto locking etc from there as well as read and reset your codes.
Make sure you have the carsoft OBDII interface for the BMW as well.
Although I havent tried it, you can also re map your ECU and re code different components using it. Bought mine from Ebay.
