I have 2 F150s (05 and 06). One has keyless entry, the other does not. I've locked my keys in the one without a few times, forgetting which truck I was in. I love that feature. I tried adding one of the Ebay stick-on keyless entries to the one without, but didn't work. Apparently they have to come from the factory with some kind of keyless code in the computer, which mine didn't have. Bummed.
