They sure did come with keyless entry. Depending upon what packages were ordered from the factory when new it could have gone either way-optional or standard equipment. However, I'm not sure how to tell by looking at codes. In the vin or glovebox sticker. I wonder if all the trucks aren't set up for it and when the buyer orders it, they just "activate" it or or otherwise "turn it on" somehow. In other words, if you don't have it and want it, maybe it's there and all you need to do is find a dealer who can turn it on.
