Once you receive your new key fob, you’ll need to program it to your BMW. Consult your vehicle’s owner’s manual for the specific programming procedure, as it can vary between models. In general, you will need to follow these steps:

  1. Insert the existing key into the ignition and turn it to position one.
  2. Remove the key and hold the unlock button on your new key fob.
