Commercial Keys

Many keys used in commercial applications are designed to thwart copying or counterfeiting, and because they are so heavily controlled, they are often difficult for collectors to find (or afford!) See more examples of commercial and industrial keys here

Industry needs security

Industry needs security

Industry needs security

 The industrial revolution brought with it large manufacturing campuses (and large hotels, etc). Master keying brought efficiencies, ease of delegation of privileges, and the need for diligent key control

Key control matters

Industry needs security

Industry needs security

This extensive set of keys, in its original wooden cabinet, are an excellent example of vigilant key control. Tags record who received what keys, when, and what they operated. (All notes are made in fountain pen or pencil)

The keys remain

Industry needs security

The keys remain

 Berger Manufacturing Company moved its administrative offices to Belden Avenue in Canton, Ohio, in 1940. The notes on these keys end in the late 1950s. Likely the office closed or relocated around that time. The campus was razed decades later

Hotel Keys are perhaps the most expressive of Commercial Keys; many  come with numbers and symbols embossed on their bows and stories on tags

This variety of hotel keys demonstrates the later tendency to rely solely on the bow for information. In some cases, for security, there is no story

Before the near-total transition to magnetic card locks, many offshore hotels used locks and keys made by American manufacturers

Many European lock companies offer high-security designs.  These examples include pieces from England, Europe and Australia
