It’s possible to lock the outside handle yet still operate the inside handle. So if someone were to unlock and open the door, but then turn the keys to the locked position - with the door open - and *then* remove the keys and go in, you now have an outside handle that’s locked and an inside handle that’s unlocked. (The interior lock locks the deadbolt only, but does not affect the outside handle). So now you’re inside the trailer, unaware that the outside handle is locked. You open the door to go out and it operates normally. You step outside with the keys inside, close the door and you have now locked yourself out.
