When locking the 2010 Sport with the key fob, it will not lock and then will give me two beeps. Per the manual, the truck is telling me one of the doors is not properly closed. Per the instrument panel all doors and hood are closed. I sprayed all locks with WD 40. no help. Sometimes when I press the fob for the fourth or fifth time, the mirrors will fold back and it will lock and arm itself. I am thinking this is something pretty simple but cannot get to the bottom of it. Any help would be appreciated.
