Back it up on a second piece of paper in a second locked box, kept in a second location.
Put both locked boxes in your will.
In response to the tornado link you've been spamming: obviously there are limitations to any security system. None of your proposed security systems particularly secure you against government agents beating you with a rubber hose until you hand over your wallet password, but I think we can agree that a reasonable level of security doesn't have to worry about that or two simultaneous tornadoes at different locations.
