How to send the valuable object

I'm afraid we'll just have to disagree on this.
Open locks are VERY crucial to the original problem.

I claim that open locks must exist, or else all
locks that exist would always be closed. If all
locks are always closed, either the box is always
locked or the box is never locked, and thus the
problem clearly has no solution.

I feel that a proper analogy must have an
open lock for this reason, otherwise, no analogous
solution can be given.

But despite our differences, I think we've brought
to light just about every issue related to this problem,
and aren't going to get any further by quibbling about
whose analogy is more appropriate.
