How to Program a BMW E46 Key


1. Get into your BMW, shut the door and put your key in the ignition. Turn the key between the on and off positions five times as quickly as you can.
2. Push the 'Unlock' button on your E46 key and hold it down while pushing the lock button three times. At this time your BMW's door locks will lock and unlock, which signals that you've successfully completed the programming process.
3. Finish programming your E46 key remote by turning your BMW on and off. Exit your vehicle and test the key.
