Keys and key control are integral parts of maintaining building security, whether it is during construction or changes in occupancy or use. Falcon offers key control solutions that enable users to control master keys within a building or facility. Key control helps prevent unauthorized access using the master key system.

  • Conventional and interchangeable cores allow for convenient access control
  • Visual and concealed key control for key and cylinder stamping
  • Multiple levels of the master keying system allows for tailoring to specific needs
  • Accessories and kits are available for maintenance or retrofit of standard and restricted keyways and cores

Conventional keyways

Open: Falcon keys and cylinders are offered as multiplex keyways and a variety of industry standard keyways (including Schlage C, Corbin Russwin 60 and L4, Sargent LA, and Yale 8 -Para).

Restricted:  Falcon offers a limited number of exclusive keyways for situations where customers are looking for a controlled distribution of keys for added security.

SFIC keyways

Open:  All industry standard keyways (A2 systems) are available to service existing accounts.

Restricted:  Falcon offers a limited number of exclusive keyways for situations where customers are looking for a controlled distribution of keys for added security.

Construction master keying is an option for conventional (non-I/C) cylinders and locksets. Cylinders are prepared with a special construction pin at the factory so that the construction master key (CMK) operates all cylinders while the building is under construction. When construction is complete, turn the top master key in each cylinder. This process moves the special construction pin into a pocket of the cylinder plug, thereby eliminating subsequent operation of the CMK.

Block-O-Key® system

  • Type of Falcon construction master keying that is used for large master key systems
  • Plastic “key block” inserted into back of cylinder plug
  • Four-pin “project key” operates all cylinders during construction
  • KB536 extractor key will remove the key block from cylinder when construction is complete
  • “Project key” will not operate once key block is removed
  • Specify “Block-O-key” when ordering


For more information on the different levels and solutions within the master keying program, view the Falcon Cylinders, Keys, and Key Systems catalog.

Multi-level master keying program

Falcon offers multiple levels (two, three and four) of master keying systems to better enable key control for a building. In addition to the various levels, selective master keying is available and useful in large keying systems to issue high level master keys to maintenance personnel.

Visual key control (VKC)

In order to better enable key control, Falcon keys and/or cylinders are stamped with the key symbol within the Falcon key system. This tells how the cylinder is keyed, eliminating trial and error. Lock mix-ups during installation or key mix-ups afterward are less likely to happen and are easier to straighten out if they do.

For greater convenience, the key symbol is stamped on the plug face or other visible portion of the cylinder front, making identification fast and convenient. The disadvantage is that stolen or lost keys can be easily matched to the locks they operate. Also, restamping cylinders when they are rekeyed results in damage to the finish.

Concealed key control (CKC)

For greater security, specify CKC on the cylinders. The key symbol is stamped in a concealed location, such as the rear of the cylinder or the side of an interchangeable core. It is not visible to the general occupants of the building, but can be accessed by authorized personnel upon the cylinder or core removal.
