I have exactly the same problem WRT the FOB functioning. I often remote start the truck - which locks the doors. Then, as I approach the truck I beging pressing the 'unlock' button, sometimes it works right away, other times it takes numerous button presses to work. I think it works better from a little further away, so I try to be twenty or thrity feet away when I press the unlock - this has given me best results. I have had no other problems as indicated above, just the occasional hard time opening the doors.
