If you need to program your new keyless entry remotes without a trip to the dealer here is how. It works, I just did two myself.


Read throught the steps before you try.
1. Removekey from ignition.

2. Remove the “BCM PRGRM” fuse from the fuse panel, accessed by opening the front passenger door. Use the legend on the fuse panel to properly locate the “BCMPRGRM” fuse.

3. Close all of the doors.
4. Close the liftgate.

5. Insert keys into the ignition, and turn the ignition lock cylinder to ACC (one click towards you – the opposite direction from starting the engine).

6. Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second.

7. Open and close any vehicle door. A chime will be heard when the system enters the programming mode.

8. Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds. IMPORTANT: After 7 seconds, a chime may be heard confirming successful synchronization. It is necessary to wait approximately 14 seconds for a second chime that will confirm successful programming. Your new remote has been accepted and all existing remote codes have been erased.

9. Repeat the previous step on each additional transmitter to be programmed (including any existing transmitters).

10. Remove the ignition key from the ignition lock cylinder.

11. Install the “BCM PRGRM” fuse back into the fuse panel.

This does work for a 2000. In some boards it shows for 01-04. The trick is to to do the ACC part as quickly as humanly possible. I spent an hour trying to get it to work. I read in one place where you needed to be quick and that was correct. Remotes are now programed.


Problem I have is the remotes need to be right at the vehicle to work. Both have new batterys. One is brand new and works the same as the older remote I had. Anyone know how the distance can be improved for the remotes to reach the vehicle?


Thanks

Not sure why you have to be so close, glad to hear you my post helped you.

Are there issues with OnStar's ability to unlock your doors remotely if you do this, or does OnStar pick up the change automatically?
