Medeco High Security Locks

Key-in-Knob cylinders are designed to retrofit knob type cylindrical locksets, lever type cylindrical locksets, padlocks and bored type auxiliary deadlatches and deadlocks. Medeco 4 (M4) key-in-knob cylinders are UL437 listed for drill and pick resistance, and utility patented pending key control. Medeco offers one of the largest ranges of retrofit cylinders in the industry, supporting the most popular security hardware.

Features:

• Medeco 4 cylinders meet or exceed ANSI/BHMA A156.30 and 156.5 grade 1 high security criteria, which includes testing for strength, durability, and resistance to surreptitious entry along with patented key control.
• Medeco 4's cylinder design includes 4 side pins made up of 3 finger pins and 1 lift pin. The lift pin is activated by contact with the movable element in the key, providing a high level of pick resistance.
• Patented key control provides protection against the unauthorized duplication of keys.
• UL 437 listing provides assurance that cylinders meet universal standards for endurance, drill and pick resistance, and resistance against other types of forced attack.
• Patented movable element in the key deters unauthorized 3D printed copies of keys or blanks.
• Angled cuts on the keys, along with rotating pins, provide added dimensions that dramatically increase key combinations. Secondary side pin bitings provide even greater combinations, making very large systems possible.
• Cylinder side pins and a lift pin which engage the sidebar prevent the key from turning until the elements are aligned in the correct position, protecting against bumping and picking.
• If you are able to cut Biaxial or Medeco 3 keys, you are able to cut Medeco 4 keys on the same equipment.
• Finger Pins work with secondary side cuts on the key to provide increased security and greater potential combinations.
• Variety of retrofit cylinders for knob and lever type cylindrical locksets, padlocks, and bored type auxiliary deadlatches and deadlocks.
• Available in popular manufacturer retrofit packages containing one cylinder and a variety of different tailpieces.
• Constructed of solid machined brass components, for extreme durability.
• Can be keyed alike, keyed different, or master keyed.
• Largest retrofit capability in the industry. Medeco is able to retrofit virtually every manufacturers' key in knob/key in lever cylinders.
