re: 2015 Jeep Cherokee started locking itself recently

I recently had an issue like this where my 2016 Ram would lock/unlock/remote start by itself. Ended up being the key fob button contacts inside came loose and this would happen when the fob was in my pocket. $15 for a replacement rubber piece on Amazon solved the problem. Don’t ask the dealer. They’ll try selling a new programmed key fob for $150+.
