talking artifact inconsistency

To get the Magic Mirror of Merlin to speak, you could apply it in
any direction (or wield it).  To get the Master Key of Thievery to
speak, you had to apply it toward an adjacent doorway or down while
on a container (or wield it).  Make the key behave like the mirror.
