Key fob

[Jeric0256]

I recently bought a 2016 Sierra Denali with 2 key fobs one didn't work so I assumed it was the battery so I replaced it and it still doesn't work.  

Am I going to have to take it to the dealer to be fixed.  The remote doesn't look like it has ever been used.

Check the manual.  Mine has to be reprogrammed inside the center console if it's not original.

One other thing.  When you took the new battery out of the package, did you remove the sticker on the back side before installing?  In the past, I have forgotten that and thought the fob was dead until I took the battery out and noticed the sticker that prevents contact.
