No battery reprogramming on the X3 unless it's 2011 or newer.

you will have to reset your express up and down windows by holding UP for 5 seconds after it closes and then hold down until it has been opened for 5 seconds. That should reset the anti trap. do for each window.

Sunroof reset is press and hold until the sunroof stops opening and closing then an additional 10 seconds after that. but I strongly recommend against operating the sunroof on an X3.
