I have found if you press the brake and hold the ignition push button for 15ish seconds a couple times it'll start (basically exiting the programming sequence, the manual has the steps if you had done it on purpose haha)

I'm still having the same issue.. After the dealership reprogrammed the 3 brand new key fobs it was fine for a couple months before acting up again. Most recently, it happened on new years eve, the next day the truck had zero power (battery had 3.4v on multimeter and wouldnt hold a charge). Put in a new battery and things fine until I had the oil changed at the dealership this week then it happened again. I'm at a loss and not about to leave the truck at the dealership for weeks for them to not fix the issue again. Honestly about trade it in and get away from chevy at this point. Edit: There was no indication the battery was getting weak and no lights/alarm, it just went bad overnight.

Keeping yall updated. Yesterday, the dealership gave me a new fob since they thought that was the issue (told them highly doubtful, but I'll take their word for it) and got stranded twice today to and from work using the new fob.. taking it back in next week when they have time to look at it again. I still believe it's whatever component/software that stores the RKE codes and authorizes new codes that's fubar.

rlambert, I got lucky (or unlucky) that I got to the dealership today before they opened and they asked me to bring it into the service bay, go out and it happened! Had a service tech come out and remote started it and he's like put it in drive and I'm like good luck, here's the fob, wait 30 minutes and you can move it

I can kinda see where they are coming from but if you have the same thing as me, it's not an issue of not recognizing the RKE, it's that it (the immobilizer or some related component) is putting itself into key learning when there's no way it should be, according to what the manuals states it requires to do so. I have been able to replicate the issue when entering through other doors, but it's completely random.

Dejadoo, I wish my problem was as simple as interference lol Glad you got your issue figured out! My truck has no issue recognizing the fob, it just puts itself into key learning mode (which should only be possible through inserting the key in the driver's side door and turning CCW 5 times in 10 seconds) and I can't get out of it until 30 minutes is up, even holding the start/stop button for 12 seconds does nothing until that timer is up. No shot the dealer is going to be able to replicate, even with my videos.

Any luck with this issue? Very similar issues happened to me about a month ago (2019 Silverado LTZ) chalked it up to a dead battery and switched to the spare fob. Replaced the battery in both to be safe, and this past week it has done it at least once every day. I can lock an unlock the truck, remote start, drop the tailgate.. everything but actually drive the thing. It will give me the same DIC message every time.. "Press Engine Start Button To Learn" (you cannot start the truck). The next message is "Remote Learn Pending Please Wait" and I have to go through the whole cycle as if I'm programming the fobs right out of the manual. I intentionally reprogrammed both fobs last night and everything worked until I tried to leave work. I have to wait for the 30 minute timeout before I can start the truck. Can't get into the dealership until Monday.
