How to Program a BMW 330i Key


1. Close all of the doors, the trunk and the hood.
2. Place the key in the ignition and turn it to position one, 'Accessory'. Turn it back to 'Off'. Do this four more times and remove the key from the ignition when you are done.
3. Press and hold the 'unlock' button and then press and release the 'lock' button three times. Release the 'unlock' button. If the locks cycle, then you have done this correctly. Repeat this step for each key you wish to program.
4. Inset the key in the ignition and turn it to 'Accessory' to exit programming mode.
