Key Systems

ASSA ABLOY Group brands were early innovators in the field of key systems. Though much has changed in cylinder mechanics and how facilities secure their doors, key systems are still the backbone of facility security, and ASSA ABLOY remains the leader in key system technology. Our brands are continuously upgrading their key systems to meet new challenges that confront the market. The most basic level of protection is a typical mechanical cylinder with a legacy key system. ASSA ABLOY Group brands offer varying levels of protection to enhance legacy key systems, including patented key systems that protect against unauthorized key duplication, geographic exclusivity that further restricts how a key can be duplicated, and cylinders listed to UL 437 offer protection against picking, drilling, and physical attack.
