I have a 18 Yukon Denali and having the same issues. I've NEVER had a remote so unreliable on ANY vehicle I've owned, especially a GM. 20% of the time, it won't even recognize the fob when I'm INSIDE the vehicle. The distance is maybe 20 feet to start the vehicle. I changed out both batteries, still...the same. There's a lot of this on the web, but no one has come up with an answer. People have even purchased new remotes and had them reprogramed to the vehicle, still...same results. Did you find a solution?
