Remote For GMC Cadillac Chevrolet Hummer Pontiac Saturn:

FCC ID: LHJ011

GM Part Numbers: 21997127

Condition: Brand New Aftermarket (No Logo)

Brand: Avicero

GM's current part number is 21997127.  Your old remote has one of these discontinued numbers: 15186200, 15186201, 15132197, 15132198, 10377295, 22730827, and 15186203.  The FCC ID is LHJ011. GM has remade this remote many times. They originally had memory #1 and #2 remotes. The purpose was for vehicles with seat memory. In reality it was ridiculous because the order that you program them determines which is #1 and #2. The numbers on the back were just for reference. In 2006 GM decided to discontinue using #1 and #2 and they started making un-numbered remotes. GM's current part number for this remote is 21997127. If you go to a GM dealer parts department you will get the new number remote no matter what remote you have now. All the remotes with the part numbers listed above are identical inside and in function so we mix them together.

Programming Procedure:

IMPORTANT: Before entering programming mode, have in possession all of the transmitters you will be using on the vehicle. Once you program the transmitter, all previous codes will be erased from the memory. The other transmitters will not be functional until you program the transmitters again.

8. Turn the ignition switch to the OFF position.
9. Release the power unlock button on the door panel. The vehicle will lock and unlock the doors automatically.
