How to Initialize Keys for a BMW 328LS


1. Close all of the doors to your BMW 328i LS. While sitting in your car, place the key in the ignition and turn it until it clicks one time and then turn it back to the off position. Repeat this an additional four times before removing the key from the ignition completely.
2. Hold down the button on your keyless entry remote that unlocks your BMW's doors. Continue to hold down the unlock button and push the lock button three times. You will hear your BMW doors lock and unlock at this point, which is required to ensure you are correctly performing the programming phase.
3. Put your key back in the ignition and turn it one time until it clicks and then remove it. Test your new remotes.
