Re: What if you pulled into a rest area...
I remember someone mentioning on a post long ago that the only way to lock your keys inside the vehicle is press the lock button on fob while when sitting inside. So if you press the lock button on the fob while inside the vehicle the doors will lock, contrary to pressing lock button on door handle (doors will not lock if fob is detected inside). And like someone mentioned above, since the fob is not outside the vehicle the doors cannot be unlocked via proximity entry, if that makes sense.
