Door keeps locking me out

[Waterloo]

Do you have a key fob, or just a key? When I purchased my truck, it came with a few keys, no key fob. I looked at the build sheet, and discovered I had keyless entry. I wonder if this is the case with your truck and the keyless entry sending unit is acting up? The sending unit is located in the passenger door, the window up down button assembly. Just a thought.
