Back in the days of ancient Egypt, the number of keys that someone possessed often reflected their social status. If you had more keys, you were considered higher up in social standing.
I do not think we can make the claim that things are the same today, considering the amount of keys janitors are required to have, and they are not considered the pinnacle of social class. In ancient Egypt, janitors may have been considered divinely inspired.
