Makes no sense to me that it would fail so soon.
Good quality locks work on boats. IMHO, they should be locked while aboard and asleep so that an errant intruder would be heard while working at it to gain entry. Then appropriate dealings could be immediately administered to the intruder.
No lock works if a thief wants in while no one is aboard or near by. Therefore, it is my premise, that while away from boat locks should be made to "look locked", but not really locked. So the thief does not wreck door, window, hatch, etc... while gaining entry to steal the same items whether door was locked or not!
