Trying to program key fob, 1999 Chevy Silverado 1500

Like the title says, I have a 1999 Silverado 1500 that I bought several years ago used, and it had no key fob. Well I finally got around to getting one, but I can't program it.

I've followed all of the steps I've found online (hold the unlock, turn ignition on and off,ect) but the truck will not enter the programming mode. Does anyone have any idea why the truck wouldn't be entering the programming mode? Thanks for any replies!

Do you have electric door locks? Is the truck a LS or LT? I have a 99 Silverado LS and I just bought a new key fob and it programmed the first try. Did you get the correct key fob for your truck?

The instructions usually say to turn the key on and off 2 times. Try 3 times instead.

I am having the same problem with my 2001 Suburban LT and my 2002 GMC Sierra 1500 SLT. My wife drives the suburban we purchased it a couple of years ago and never got a remote with it so today i stopped at local graveyard and purchased a remote and followed the steps online and the vehicle would not go into program mode. I also tried turning key three times instead of two times. My Sierra has Keyless Entry so i tried it on that and it would not go into program mode either. Any advice?

It's an LS model... And I'm not sure it has the RKE option, but considering it wont enter program mode, maybe it doesn't?

About the key fob, I'm also not sure if it is the correct one, but being as the truck wont go into program mode, I haven't had the chance to find out. It should be the right key fob though..

Thanks for the replies. How would I go about finding out of it does indeed have that option?

Looked in glove box.. Not sure what the "option tag" is..?

I just saw a sticker that had a bunch of random numbers and letters in sets of 3...
