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.
