My truck alarm keeps going off randomly with no one messing with it. I tried disconnecting the battery, and then I also tried replacing the battery in the fob. Also tried holding down the unlock button on the fob while trying to start the truck. Still nothing.

Hey James, sounds like you may have a bad sensor, but it can be something else too. On some vehicles you can access the alarm system with a computer (at the Dealer) and it will record the last several reasons the alarm was set, this is very valuable info when trying to figure this out. One thing I would do is try to get that info and have the dealer check for any known issues with these systems. Another thing is to arm the alarm, then go around and push and pull on each door, it's possible one of the door switches is causing the alarm to go off, and this method may help find that switch.
