Need help finding correct key fob

[Shiny]

Here’s the 2 button fob. I just picked up one two weeks ago. Works perfect.

Wow, the ACDelco ones got cheap! I'll have to buy a couple for my 97.

Just picked up my 99 but it didn't have fobs. Took it straight to the shop for some suspension work but wondering if my model uses them....hmmm. Was told if I had the AUO code, then yes but if not, then no....guess I'll see when I get the truck back.
