GMC16SLT

Started having the same issue on my 2016 GMC Sierra SLT my mirrors would fold down and my doors would toggle lock while driving, after troubleshooting this annoying issue I decided to remove the battery from FOB and use my spare one what do you know problem solved, went and had another FOB made with my locksmith he said it’s a open circuit or a sticky button from years of use.. hope this helps someone else
