High Security Open Conventional Patented Keyway
The Degree Key System
The patented Degree system from SARGENT provides the right level of security for each opening in your facility. Three levels of ANSI/ BHMA Grade 1 protection, from patented keyway to UL437 certified, secures every opening. A common key for all three levels of security enhances key control and simplifies administrative procedures. Key blanks are controlled through authorized distribution and geographical protection is available. Available for mortise, rim, component and Large Format Interchangeable Core (LFIC) cylinders, SARGENT offers the right Degree of protection for every door in your facility.
Benefits
Patent protection from unauthorized key duplication through 2027 New keyway family protects system integrity from legacy systems Keys are significantly stronger than competitive systems User-friendly design with minimal components provides easy field service Availability in all existing SARGENT cylinder types provides cost-effective upgrade for SARGENT facilities Bump resistance for added protection Degree Level 1 (DG1) features a utility patented keyway and provides protection against bumping for mortise, rim and component fixed cylinders. These cylinders easily retrofit into existing hardware and are appropriate for most applications. The keys for DG1 can only open DG1 cylinders. Degree Level 2 (DG2) builds on the utility patented keyway of DG1 and adds patented side bar locking with unique angled bottom pins that provide end users with geographical exclusivity. Cylinders provide protection against bumping and picking. Because of its superior key control and patent protection until 2027, DG2 products are recommended for use in conjunction with DG3 for new installations or when retrofitting systems, including large format interchangeable core systems. Degree Level 3 (DG3) combines the utility patented keyway and side bar locking with unique angled bottom pins that provide end users with geographical exclusivity, and adds certification to UL437. They are classified as high security because of their superior resistance to physical attack and protection against unauthorized key duplication. Because of its superior key control, patent protection until 2027, and physical strength, we recommend DG3 products for new high-security installations or when retrofitting systems, including large format interchangeable core systems. SARGENT also offers anti-vandal and high security locksets that complement DG3 cylinders for those openings most vulnerable to attack. IMPORTANT: Sargent DG1 key systems are available with 7 depths of cut while DG2 and DG3 are only available with 6 depths of cut. DG1 systems can utilize all 7 depths in system design only if not integrated with DG2 and/or DG3 systems. If DG1 patent protection is the only requirement in the key system and there is no expectation of combining with DG2 or DG3 levels of security, then all 7 depths are available for use.
