I do not have a 2nd fob. I bought the truck used

Thank you for the input! As far as I know there are not any error codes. When I start the truck normally there are no lights/messages on the dash. Not sure if it’s related but I’ve also noticed that the horn doesn’t always honk when pressing the lock button twice. The horn works fine otherwise.

I have a 2015 Sierra 1500 and the remote start has been acting up for a few months now. About 1/2 the time it doesn't do anything. 1/4 of the time it will start for a second or two then turn itself off and 1/4 of the time it works as it should. I replaced the key fob battery but it did not make a difference. The hood open light never comes on so not sure if that’s related?
