Ok - just got this 2013 dodge 1500. Everything worked as designed, until yesterday....
On exit, I open the doors, all the doors unlock and then about 5 seconds later, they all lock without me doing anything. Well that's strange, I don't recall changing anything in settings.
Also, the little lock button on the exterior door handle doesn't work - lock or unlock.
When you get in the truck, the doors lock immediately and the horn sounds 3 times.
FINALLY, the drivers door inside lock/unlock switch stopped working - all this started happening yesterday.
