2019 Sierra SLT. Remote start will not work. I've checked all the security features it needs to operate. Tested battery. 12.4 volts. After pressing the lock on my key fob, I then hold the start button. The lights flash but the start process does not initiate. Every other function on the key fobs work. The truck will start manually by pressing the start button on the dashboard. I have also replaced the batteries in my key fobs. I also have the My GMC app active. It sends the start function to the truck. Flashes the lights but does not start. Any suggestions?
Hey everybody. I own a 2011 Silverado 1500 LTZ, and in the glove box I have the RPO code AP8. I purchased a Dorman 4 button fob included with an OBD2 programmer. I followed all of the steps to program, and the fob works with locking/unlocking. However, when trying to remote start, the blinkers flash like they saw the trigger, but the truck doesn't start. Being that I have AP8, what else do I need to do in order to make this work? My local dealer is asking for $330 for a new fob and programming (saying there is more involved than just programming a fob), but if this is something I can do myself with the right equipment, I'd like to think I can handle it. Thanks.
