I have a 2003 GMC Sierra. I switched the battery in my keyless remote. I tried to hold down lock and unlock for about 10 seconds, but nothing happened. Am I doing this correctly, or is there something I'm missing?

  Thanks, it’s a 442 tribute. Not something I would have done personally but it was an older resto and has all the correct bits already. Including a correct 400 olds motor sitting in the garage that I gotta tend to eventually. 5.3 and Muncie is actually a delightful little combo though, so I’m in no hurry. Aside from the fact that I also have a 1991 Infiniti M30 rag top that could use an LS swap too. Might have to do some horse trading between the cars some day. Funny enough there’s a Lil Red Express at the show today. I’ve seen quite a few of them over the years. Or just the same one goes to all the shows! 🤣
