How Do I Program My BMW Key Fob?

Programming the keyless entry on your BMW key fob is a simple procedure that most drivers in and around the Chicago area won’t have trouble doing. There are two basic methods: one to use when you already have a key fob that works but want to program additional keys, and the other when you are starting from scratch without a working key.

Programming Additional BMW Key Fobs

If you want to know how to program extra keys, follow these steps below:

1. Take the working key fob along with the ones you want to program inside the car with all doors and windows closed.
2. Put the working key into the ignition and turn to position 1. At this point, the dash lights and accessories should turn on.
3. Turn the key back and remove.
4. On the working key, hold down the unlock button and press the lock button (the BMW logo) 3 times, then release the unlock button. The doors will then automatically lock and unlock.
5. Take the new key and hold down the unlock button while pressing the BMW logo 3 times, then release the unlock button. Again the doors should lock and unlock, and you’re done.

Programming a New Key from Scratch

The instructions below are for programming a new key when you do not have a working key fob.

1. Insert the new key into the ignition and turn it to position 1 and back 5 times rapidly.
2. Remove the key.
3. Hold the unlock button and press the BMW logo 3 times, then release the unlock button.
4. If you have additional keys you need to program, repeat step 3 within 30 seconds from the original key programming.
5. Turn on the ignition to complete the process.
