my issue fixed by followign these steps..


1. With both keys, get in the car and close all windows and doors.

2. Put working key into the ignition and turn to position 1 (the accessories should turn on)

3. Turn the key back to position 0 and take the key out of the ignition.

4. Using the working key, hold down the unlock button, press the BMW logo (lock button) 3 times, and release the unlock button. Doors should lock and unlock.

5. With the new key, hold down the unlock button and press the BMW logo (lock button) 3 times and let go of the unlock button. Doors should lock and unlock and you're done!!
