Replaced factory cargo & third brake light bulbs (921) with led. The next morning I tried to start truck & key fob was not detected, got my extra fob & also didn’t work. It unlocked doors & remote start worked, so I replaced batteries & no luck still not detected. Long story short I put factory bulb back in third brake light and sure enough the key fob was detected! Ridiculous how something that simple is tied into the fob, hope this helps anyone with similar situation.
