Multiplex/Simplex Keyways

Multiplex keyways can be used together to expand a keying system. A simplex keyway is independent, stands alone and cannot be tied into any other keyway to expand a keying system.

All/Multi-Section/Single Section Keys

All/Multi-section keys can be used on more than one cylinder with different sections.  For example: a key cut on the L41 multisection keyblank will pass cylinder in the L1, L2, L3 and L4 keyways. Single section keys can be used with cylinders of the same section. For example: a key cut on the L4 single section keyblank will only pass a cylinder in the L4 keyway.

Active Keyways

Keyways which are available for new Corbin Russwin keying systems are considered active. In the case of new master key systems, the factory reserves the right to select the keyway from a range of standard keyways, based on usage in a particular geographical area.

Inactive Keyways

Many older Corbin Russwin keyways are designated inactive. No new systems shall be established on these keyways.  However, they continue to be available to support existing keying systems.

Restricted Keyways

New systems on restricted keyways require prior approval of Corbin Russwin Key Systems Administration. For security reasons, these keyway profiles are not shown.

Patented Keyways

New systems on patented keyways require prior approval of Corbin Russwin Superior of Key Systems Administration. Patented keyways are available for jobs which require protection against unauthorized duplication and require an agreement to be signed between Corbin Russwin and the end user.  Keyblank, cylinders and plugs with patented keyways are only supplied to distribution when a proper letter of authorization from the end user accompanies the purchase order. For security reasons, these keyway profiles are not shown.

Pyramid Keyways

Pyramid keyways are only available for Pyramid cylinders and separate specifications are used from conventional Corbin Russwin keying systems. New systems for Pyramid require a Notice of Acceptance document to be on file with Key Systems Administration. All orders for Pyramid must have a system specific Registration Certificate attached and all products must ship directly to the end user unless a quantity - specific Letter of Authorization accompanies the purchase order. For security reasons, these keyway profiles are not shown.

Bitting Classes

Corbin Russwin has several sets of dimensional standards for bitting (cutting) keys. If the wrong specifications are used when making keys on code machines in the field, they will not operate in conjunction with factory supplied cylinders and keys. The bitting class is given for each group of keyways. All bitting specs are available in the Corbin Russwin cylinder manual.
