I have an old model 2000 BMW and the car doors will not unlock. I tried everything - there is nothing wrong with the batteries in the remote and when I try to unlock with the button inside the car. they still won't unlock. I can drive it because the driver;s side door has a place outside the door to input a key to lock and unlock, but the other 3 doors is a problem, not to mention.. the gas tank will not unlock unless all four doors are unlocked at the same time.
Anyone ever experience this? What can I do? Dont really have the money to have a mechanic look at it right now,
