2021 Silverado 1500 RST with 6.2, Push button start/stop. I had one key fob, tried to program a second one. First locksmith could not get a fob to program. Got to the message that says ready to learn remote 1. Placed new fob in pocket between the cup holders. Press start/ stop button and nothing happened. Drove home and then the original fob stopped working. The original fob would not do anything. DIC kept saying no remote detected. Could not start the truck, etc. called mobile locksmith, they worked for like two hours, using programmers, their fobs, the gm computer, etc. No Luck! Had trucked towed to dealership. Now five days later, the dealership can’t get anything fobs to program or work. Was able to get truck started once they said but nothing else. Have had GM engineers investigating as well. Anyone have this happen? Any ideas? Bout ready to just wire a key type ignition in, lol..
