The GMC Yukon Denali is among the best selling sport utility vehicles from GMC. It is known for its size and luxury features, but it also has many of the same standard technologies as other GMC vehicles. Among these is the keyless entry feature, which allows you to program your car's door locks, trunk hatch and panic alarm to a wireless remote that can be added to your keychain.
Enter your car and insert your key into the car's ignition. Be sure to close all of the car doors and the trunk behind you.
Press and hold the Unlock tab on the driver's side door.
Cycle your key in the ignition to the "On" position and then back "Off" twice in a row.
Wait for the locks to click after the second cycle and then press and hold the Lock and Unlock buttons on your remote.
Hold the buttons for up to 30 seconds until the locks click again and then release them. This will complete the programming sequence and you can remove your key from the ignition to end the process.
