The first thing that I did after purchasing my 2016 39MB was to remove the keyed locks, replacing them with plain thumb latches. Don't have to fiddle with a key to open storage doors & since I don't keep anything really expensive in there anyway (beach chairs, umbrella, patio rug(s), etc.) I'd rather have them help themselves to this stuff if they want it that bad than break & damage my doors trying to gain access. As the others said, the best & toughest lock in the world won't keep anyone out with heavy tools.
