The latest in modern techniques and equipment are used to apply the highest quality finish. Extra steps assure durable, consistent finishes and long useful life.

Although we apply the finest available protective plating and/or enamel coating to the surface of our products, these finishes have limitations and in time may deteriorate either from exposure to weather, pollution, perspiration, extremes of climate, frequency of use or other factors. Deterioration of these finishes is, therefore, not a defect, but a normal process which is unavoidable. Our company cannot accept responsibility for finish deterioration in these circumstances; therefore, the finishes cannot be guaranteed. These products will not be refinished or replaced under our warranty should deterioration of finishes occur.

Choose the right key system for your application.
Schlage Classic and Everest 29™ 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. The perfect mix of performance and flexibility.
Unlike many other brands of high security cylinders, Schlage can easily integrate 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 conventional 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.
Primus XP – high security.
The Primus XP keyway provides various levels of geographic exclusivity and requires authorization for duplication, ensuring better key control.
• Patented protection until July 2024
• Cylinders have a second set of pins for added security and pick resistance
• UL 437 versions available for additional protection against drilling and physical attacks
• Operates Primus XP and Classic (open) cylinders
The Everest 29™ patented keyway family
Everest 29 patented keyways provide a higher level of protection against unauthorized key duplication. Their patented design prevents non-authorized sources from manufacturing and distributing Everest 29 key blanks. Our Everest 29 key systems are suited for both new and existing key
systems, and give you the flexibility to expand and upgrade your key system as your needs change.
What is Everest 29 Primus XP?
The highest level of keyway security, Everest 29 Primus XP keyways are distributed under careful protection guidelines to protect the exclusivity of the individual side bit milling patterns. Choose Everest 29 Primus XP when the highest level of security and protection against unauthorized duplication is needed.
• Geographic exclusivity on key blanks
• Multiple patents protect against unauthorized key manufacture through July 2029
• Pick- and rake-resistant design
• Can be mixed and matched with non-Primus XP cylinders
• All key sections and master keying available at all levels of security

• Keys are quick to cut and cylinders are easy to pin
• Thicker keys for added strength
• Three-year product warranty and a limited life-time warranty against key breakage
• Operates Everest 29 Primus, Everest Primus,  and Everest restricted cylinders
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® 29™ Primus XP high-security cylinders, Everest 29 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’s high quality conventional cylinders provide the standard level of security and functionality for Schlage locks. The exclusive use of solid brass bar stock plugs and shells, phosphor bronze springs, nickel silver keys and bottom pins, ensures long life and ease of operation. 6-pin Everest 29 cylinders in S123 keyway with two patented keys are standard for stock. S145 is standard for new master key systems.

Primus XP High Security Cylinders
Primus XP high security cylinders are available to add patented* key control and varying degrees of geographical exclusivity to most Schlage 6-pin key systems, whether using Everest 29 or Classic keyways. In addition to a conventional pin tumbler mechanism, Primus XP cylinders incorporate a patented* finger pin and sidebar design providing a “dual-locking” cylinder that is highly pick-proof. Resistance to drilling and other physical attack is optional by specifying 20-500 Series UL437 Listed cylinders. *Patented key protection applies to Everest 29 Primus XP and Classic Primus XP only.
Primus XP Lockout Cylinders
Available in rim and mortise cylinders only, lockout cylinders are designed for doors where it is frequently desirable to disable all keys from operating the lock temporarily. 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.

Interchangeable Core (IC) Cylinders
(Full Size and Small Format)
For use where fast rekeying by non-technical personnel is desired, Schlage Primus XP and conventional interchangeable cores offer a great blend of security and convenience. The special control key for the system is all you need to remove the old core and install a new one. The core itself can be rekeyed with standard Schlage pin kits. Unlike some other brands, Schlage interchangeable cores can always be integrated into existing systems with no adverse effect on the key system. IC locks are especially well-suited to chain stores and restaurants where frequent employee turnover requires immediate rekeying by store management. Use IC cylinders to save time and energy when changing labor-intensive locks on exit devices and other door hardware.

Full Size Interchangeable Cores
Schlage® interchangeable core (IC) locksets allow immediate rekeying at the door simply by using the special control key to replace the core in seconds.
Available in all lever designs and the Orbit knob, full size interchangeable cores can be integrated into any 5 or 6-pin Schlage key with no adverse affects on keying capacity.
