Lost your keys or just need a spare? This set includes TWO fully functional replacement keys with integrated remote key fobs for your 2003-2006 GMC Yukon XL 2500. They come from Wholesale-24-7 (part number for LHJ011, 21997127, etc.). The remotes have batteries already installed. Here's the important part: they ARE self-programmable for your listed Yukon model – you'll get a card with a website link for the programming instructions. Just follow the steps with your vehicle. Note: For some other GM models (like Equinox), dealer programming might be needed, but for your Yukon XL, you should be able to do it yourself. A black finish, brand new in packaging. UPC 039294324400. Get a backup set before you're locked out!
