USPS uses key locks seemingly designed by Ben Franklin himself. Look at them someday. FedEx boxes used to have Simplex 926 5 pushbutton ""locks"" if you stretch the point.
Don't let the old-fashioned look deceive you. Most mail storage boxes use lever tumbler locks (similar to what's used in safe deposit vaults, though obviously the mailbox locks have a flimsier plug). Lever tumbler locks are in general much harder to pick than pin tumbler locks (the kind on most doors).
