good afternoon everyone. Got an interesting one here hoping for some help. Have a 25 1500 Rebel X model with about 6900 miles. Was out working today and things were fine and all of a sudden I lost the use of the key fob. No buttons at all work but the truck will still start. Came home and test battery in it, good. Went and grabbed the spare fob and same thing. Have to use the app to lock and unlock the doors. Any ideas before I head to the dealer?
