So the latest on my Titan is that when it gets hot out (like over 90 degrees, I live in the Central Valley in Northern California) my key fob won't lock/unlock my doors. I thought this might be a key fob problem, so I switched to the 2d one I got when I bought my Titan, same problem. So I replaced both batteries, same problem. It always works in the mornings when its cool out, but as soon as it warms up, I can hit the button until the cows come home and nothing happens, so I have to use the key in the door to lock my truck and to unlock on hot days (and we have more than our fair share here).
So has anyone else had this problem???
