Medeco

Founded in 1968 in Salem, Virginia, Medeco emerged from the Mechanical Development Company, a tool and die shop whose owners developed a revolutionary locking principle using angled key cuts and rotating pin tumblers that set new standards for high-security locks. Now operating as an ASSA ABLOY Group brand with approximately 250 employees at its 130,000 square-foot Salem manufacturing facility, Medeco has evolved through multiple generations of patented technology including the Original, Biaxial (patent expired), Medeco3 (M3, patent protection until 2021), and the current flagship Medeco4 (M4, patent protection until 2028). All Medeco high-security cylinders meet rigorous industry standards including UL437 listing for drill and pick resistance, ANSI/BHMA A156.30 Level A certification, and Grade 1 ANSI/BHMA A156.36 compliance for deadbolts. The company's product line encompasses SFIC and LFIC formats, rim and mortise cylinders, key-in-knob/lever configurations, and the innovative Medeco XT electronic cylinder system that provides audit trails and flexible scheduling without wiring, powered entirely by the intelligent key. Medeco's patented rotating pin tumbler technology incorporates hardened steel inserts, false sidebar notches, mushroom and barrel driver pins, and the unique slider mechanism (in M3 and M4 models) providing superior protection against picking, drilling, bumping, and unauthorized key duplication. Their Maxum deadbolt exceeds Grade 1 standards with solid brass construction, free-turning collar, and quarter-inch mounting bolts. Serving government installations, military facilities, financial institutions, healthcare facilities, educational institutions, and commercial enterprises worldwide, Medeco maintains strict key control through authorized dealers only, requiring security cards for duplication authorization, making it a trusted choice for applications demanding the highest levels of physical security and key control.
