A video tutorial on how to program a remote key fob to 2021 GMC Yukon, including Yukon XL and Yukon Denali

*This programming procedure requires that you already have two working remote fob keys for your 2021 GMC Yukon. If you have less than two working remote key fobs then your GMC Yukon will require a Dealership or Automotive Locksmith to program additional keys.

The 2021 GMC Yukon owner's manual contains the following information on adding remote fob keys.

Programming with Recognized Remote Keys
A new key can be programmed to the vehicle when there are two recognized keys. To program, the vehicle must be in run and all remote keys, both currently recognized and new, must be with you.

1. Place the two recognized remote keys on the passenger seat.

2. Scroll to the DIC menu to "Remote Key Learn" menu and select. The DIC displays READY FOR REMOTE #3, 4, 5, ETC.

3. Place the new remote key into the backup pocket in the left cupholder.

4. Press ENGINE START/STOP. When the remote key is learned, the DIC display will show that it is ready to program the next remote key.

5. Remove the remote key from the backup location and press UNLOCK or LOCK on the remote key. To program additional remote keys, repeat Steps 3–5. When all additional remote keys are programmed, press and hold ENGINE START/ STOP for approximately 12 seconds to exit programming mode.
