Once that is done then both your CA and key (s) will be good to go. The non CA key does not need pairing. Once you order it as per VIN, it is ready for use once you pick it up.

Lastly, if you need to replace the ibs sensor, you might need to change 3 cables. I have a 2006 330I. The old sensor was two pieces.
