So my parking lights stopped flashing when I lock or unlock the truck with the key. Just out of the blue, no warning or problems. Any idea what's going on? I tried the reprogram procedure as outlined in the owners manual, but get no response. Also put a new battery in the key, still no response. The head lights still come on and go off normally and the bed light also comes on and off normally,Horn chirp is also working. Anyone???

 

If everything else is still in working order I would disconnect both batteries for at least 30 min and reconnect. This will reboot the system.
