Two hidden secret features on the key fob for the 22 / 23 GMC Yukon/Yukon XL Denali, plus a bonus.

If you have made it this far here is your bonus.
Take the key code tag and put it in your safe place. Don't keep it on the key chain or key fob or in the vehicle, take it, and as I stated proper registration and ID to a local Dealership parts department and they can order you a new key fob. Most of the time they get a temp key fob programmed so you can at least start the Yukon and drive. Please know that it will take some time to order and get the set of key fobs in and programmed.
