: Just picked up my new 328i on Saturday (silver/grey, premium, HK/CD, htd sts, alarm) and its great except for a key problem.

: I can't seem to program/initialize one my keys for activating the remote locks and alarm.

: One of the keys works fine, but one won't unlock/lock and disarm/arm the doors and alarm.

Your dealer is supposed to perform this service for you. Did you buy and install the alarm yourself, or did you have your dealer do the installation. In either case, the dealer must use his DIS system to re-program its computer to accept input from the alarm. A 5-minute job, but some dealers have tried to charge up to an hour's labor.

Take it to your dealer and press him to program the alarm and the rest of the system. I understand that BMW pays the dealer for up to two programming sessions, so if they charge you, they are getting paid twice for the same service.


: The manual provides a procedure like this:

: 1. Get in the car
: 2. Insert the key to be programmed in the ignition and move it to position 1 for less than 5 seconds and then remove it.
: 3. Press and hold unlock on the key
: 4. Press lock 3 times within 10 seconds
: 5. Release the unlock button
: 6. The locks lock and then unlock and the key blinks 10 times.

: Great, now I can unlock and lock the car with the key that wasn't working.
: But!! The key that wasn't working (that I used to get into the car) doesn't work any more.

: I have gone back through the procedure to get the original key working, but then the second key won't work.

: Any tips on getting both keys to work?

: Aside: If you use the valet or spare key to lock/unlock the door, does this arm/disarm the alarm as well?

: Thanks.
