Choose the right key system for your application

Schlage Classic and Everest key systems are designed to give you the level of security you need for every application. With optional keyway exclusivity, multi-level key hierarchy and cylinders that fit into a wide variety of locks, Schlage key systems and cylinders give you total control of your key system and building security. Unlike many other brands of high security cylinders, Schlage can easily intergrate its Primus XP and conventional cylinders into the same key system with no adverse effect on keying capacity. Primus XP keys will operate conventional cylinders, but conventional keys will not operate Primus XP cylinders. This means you can secure exterior doors and sensitive areas with Primus XP cylinders and use convential cylinders on the remaining doors. This cuts the cost of the overall job, and security can be tailored to meet the exact needs of each door without sacrificing the convenience of having a single building master key.

The Classic keyway family

Schlage Classic keyways provide security with no restrictions on duplication. Our Classic keyways can be easily upgraded or mixed with Primus XP for enhanced protection.

Choose the Right Cylinder for Each Application

Schlage cylinders are ideal for a wide range of commercial applications, including airports, hospitals, schools and universities, government and military buildings, offices and research laboratories. Choose from Classic Primus XP® or Everest® Primus XP high-security cylinders, Everest patented open and restricted cylinders, or the industry-standard Classic cylinders to fulfill your security needs and the demands of your specific installation.

Conventional Cylinders: Schlage locks are provided with cylinders precision-built to extremely close tolerances and the highest standards of accuracy. Using only solid brass bar stock plugs and shells, phosphor bronze springs, and nickel silver keys and bottom pins ensures long life and ease of operation.

Primus® High Security Cylinders: Primus high-security cylinders are available to add patented key control and varying degrees of geographical exclusivity to most Schlage 6-pin key systems, whether Everest or Classic keyways. In addition to a conventional pin tumbler mechanism, Primus cylinders incorporate a patented finger pin and sidebar design, providing a “dual-locking” cylinder that is virtually pick-proof. Resistance to drilling and other physical attack is optional by specifying 20-500 Series UL437 Listed cylinders.

Primus Lockout Cylinders: For doors where it is frequently desirable to disable all keys from operating the lock temporarily use lockout cylinders. The special lockout key can be removed while the plug is turned to the 11 o’clock position, preventing all normal operating keys, including master keys, from fully entering the cylinder. Suggested applications for lockout cylinders include laboratories, dark rooms, clean rooms and exterior doors to dormitories. Schlage will not master key lockout cylinders.

Caution: Double cylinder locks are a life safety hazard in times of emergency and their use is not recommended. Installation should be in accordance with existing codes only.
