Keys and key control are integral parts of maintaining building security, whether it’s during construction or changes in occupancy or use. Falcon offers some of the most versatile and easy to use cylinders and keying systems in the industry. Our interchangeable cores can be removed for quick, easy re-keying and are compatible with SFIC products from other manufacturers. Our multi-level master key program ensures safe, accurate key control. And our full line of mortise cylinders ensures maximum durability, performance and security no matter what the application. Most important, every cylinder, key and keying system we make is backed by one of the best names in the business.

Interchangeable core (I/C) offers maximum flexibility to the building owner. Whenever a key is lost or stolen, locks can be rekeyed quickly by non-locksmith personnel. All it takes is the special CONTROL key. This key is used to remove and install all cores in the system. Just go to the door, remove the old core and install the new one with the control key. Security is regained in seconds!

Falcon’s interchangeable cores and I/C locksets are compatible with other small format interchangeable core (SFIC) products, such as Best and Arrow. Use our locks with their cores and viceversa. In most cases Falcon can even furnish cores master keyed into your existing Best or Arrow key system. Just include a copy of your existing bitting list with the order.
