BMW X3 Key Programming
The transponder technology within BMW keys is complicated. If your fob or key isn’t working, it may be because it has become de-synchronized.
Want to know how program your BMW X3 key?
Sitting in your vehicle with the doors closed, turn the ignition to position one. After five seconds, turn it off and take the key out. Hold the unlock button for fifteen seconds. While holding it down, press the lock button three times, and then release both buttons. If your key is reprogramming, your car doors should lock and then unlock.
