Rekeying can be done by non-technical personnel without removing hardware from the door. When used system wide, IC provides tremendous rekeying convenience. When planned from the inception of a system, IC cylinders can be integrated with conventional cylinders.
IC is recommended for virtually all types of keying systems, such as office buildings, hotels, schools, hospitals and universities. When used in exit devices and other installations which are labor intensive to rekey, IC saves time and money over the life of the building.
All operating keys (change, master, grand master) operate the lock normally. To rekey, use the special control key. The control key operates at a separate shear line in certain chambers within the core. Only the control key is required to remove and install a core.
Cores are available in 6-pin (standard), 7-pin, security and Pyramid. Two nickel silver change keys are furnished standard per core. Control keys will be furnished when ordered.
Corbin Russwin recommends temporary construction cores for greater security. Special construction master keying is also available, when planned from the inception of the keying system.
Concealed Key Control (CKC) is available for all Corbin Russwin cores.
