I need to be educated

[Borrego]

One of the things I enjoy about this site is there are folks here with some serious technical and practical knowledge on a broad spectrum of subjects I do not possess. Case in point is the Craftsman tool box pictured below. Can someone tell me what on Earth the cylindrical shaped hole is for?
I do not believe it is associated with the lock above it because that controls the locking mechanism for the drawers. I am absolutely baffled.

looks like it may have been a security lock to keep that drawer locked while the rest was open...

Seperate lock for a security drawer

Separate lock for that drawer to put your wallet in during the day.
