The only thing i would have done differently was just get the remotes without keys and buy the keys with gmc on them separately from someone else. They work great just had to have a key guy come and program them both key and fob work with no problems. The key looks and feels just like the factory key. The fob was much easier to program, then than expected. Youtube has a number of videos that giving you step by step, instructions that are very easy to follow. The fobs have batteries in them. These work just great with my chevy tracks, great product, extremely happy and easy to set up perfect for my daughter’s truck and the directions were super easy to carry out and program to her truck spot on. Well, i just got it, but for now easy to pair and for the price i, like it, Applause, Music, great items. I was missing my key fobs when i got my truck. This makes it so much easier on icy mornings when the keyhole is froze shut. The extra keys are nice too. The panic button is a little sensitive as a heads up Music. You have to follow the instructions to activate the fobs.
