I have never locked the handle and only use the deadbolt. Never really understood why there were 2 keyholes.
The door latch accepts a master key. Every dealer salesman, maintenance guy, yard boy, and broom pusher has a master key that will open the latch on the door, there are probably tens of thousands of those keys out there. This way when a dealer is showing you trailers, one key will open all the doors to RV's you want to look in (the dealer never uses the deadbolt lock).
The deadbolt lock takes a more specific key, there are probably only thousands of those out there. Your baggage doors, everyone in the world has a key for those.
