Key FOB programming is definately not a dealer only job, as much as they'd like you to think it is!:disappoin Try this procedure. It's a pretty standard procedure across the GM line: (write-up compliments of nat3ten from trailblazer forum)

BMW 7-Series - Key Remote Programming
Three methods to try:
Method 1:
1. Working from within the vehicle and with the doors shut
2. Turn ignition to position 1 and back to off within 5 seconds.
3. Remove the key from ignition and press and hold the unlock button for 15 seconds during this time press the key lock button 3 times within 5 seconds.
4. Release both buttons.
5. Doors will lock and unlock to show correct programming has occurred.

Method 2:
To do this procedure you need to have one working key and one key that needs to be programmed.
1) Get in and close all doors.
2) Turn on the ignition and turn off quickly. (No more than 5 seconds) to start the process. Next action must take place within 30 seconds.
3) Remove the 1st key.
4) Hold the key up near your left shoulder (this is so it is closer to the remote receiver antenna.
5) Hold down the unlock button and press the lock button 3 times. Release the unlock button and the doors lock which confirms the operation.
6) Quickly repeat steps 4 & 5 for key #2 etc.
If it does not work, try doing the keys in opposite order. Key 2 then key 1, vs 1 then 2.

Method 3:
Alternate if you do not have a working remote
1. Turn key to position 1 five times very quickly 2. Remove key 3. Hold unlock button then press lock button 3 times, release unlock button.
4. If you have another key do the same button pressing within 30 seconds 5. Turn on ignition to finalise.
PLEASE NOTE: This programming procedure programs the remote control part of the key. Any transponder chip for the immobiliser (starting of car) will not be programmed and must be done by a specialist.

I had the same problem and located the addendum to the owners manual. It's kind of overcomplicated it seems. Here is what it says:
1) Confirm all doors are closed and the key is out of the ignition.
2) Open the driver's door and put the key in the ignition within 10 seconds.
3) Remove the key within 10 seconds.
4) Push and release the driver's door switch 3 times within 20 seconds.
5) Insert the ingition key within 10 seconds.
6) remove the ignition key within 10 seconds
7) press and hold both "lock" and "unlock" on the transmitter for more than 5 seconds within 20 seconds of removing the key All doors will lock/unlock to confirm the process has been properly done.
8) Press "lock" or "unlock" on the transmitter within 5 seconds of completing step 7. All the doors will lock/unlock to confirm that the process was properly done.
At this point the transmitter has been properly programmed.

Of course, this didn't help me. My transmitter still does not work. I did confirm the procedure with a known good transmitter, so it is valid. If the lock/unlock does not happen in step 7, you more than likely have a bad transmitter.
