Well, you might be over-thinking it somewhat. There are actually a variety of boxes like this, used for a variety of things.
The box you refer to is not the most common. The most common is what is known as a "Knox Box", and these are anything but insignificant, fragile, key
holders. They are required by Code across the nation for Fire Departments to enter buildings and access elevator fire control keys. They are made
from hardened steel and near impossible to breach. Yes, I suppose they could be breached...eventually...but not before most other means of entry were
much more easily employed (i.e. breaking a window, breaking down a door, etc.)
The other, more residential, version of these things came out of the Real Estate industry mostly. They are were used initially to allow multiple real
estate agents to gain access to a home for presentation to a client. These are usually just flimsy cast pot metal with a combo lock. A lot of them
actually hang on a door knob, but the one you've pictured screws to a wall.
