This come as a choker to me. I was not aware that the key that open your outside storage compartment of my T.T. is a universal key. CH-751, why even bother locking this compartment if anyone else can ...
If you think about it, if someone wants in to a RV door or storage area, it doesn't matter much which lock you have...most can be defeated in seconds with other tools. Locks are really only good for keeping young children and honest folks from getting in.
I read about someone using a 4" round saw on a cordless drill and got in the deadbolt locked RV door in less than 30 seconds. The storage door locks can be twisted open with a screwdriver or locking pliers in the blink of an eye.
