Medeco High Security Locks

Building on more than 50 years of lock engineering innovation and offering the highest level of protection against physical attack and unauthorized key duplication, patented Medeco 4 (M4) cylinders are UL 437 Listed with solid brass construction and hardened-steel inserts to thwart drilling attacks. Medeco 4 cylinders are designed to help give every opening the highest level of security as possible. In addition to pins that lift and rotate, M4’s design includes 4 side pins: 3 finger pins and 1 lift pin, providing a high level of pick resistance. The patented M4 key design with its movable element protects against the emerging threat of additive manufacturing (3D printing) for superlative credential security. The technology built into M4, including the movable key element, and side and lift pins in the cylinder, stretch the boundaries of features that can be built into a lock and key system.

Features:

• Key Control: Patent-pending key control protects against unauthorized duplication of keys.
• Protection Against 3D Printing: A patent-pending movable element in the key deters against unauthorized 3D printed copies of keys or blanks.
• Picking and Bumping Protection: M4 cylinders use cylinder side pins, a shuttle lift pin and a movable key element to engage a sidebar that prevents the key from turning until the elements are rotated and aligned in the correct position, protecting against bumping, picking and other attacks.
• Uses Existing Hardware: M4 cylinders are available in a wide variety of formats, retrofitting most hardware on the market.
• Protection From Physical Attack: M4 cylinders are UL 437 listed and UL test lab proven to stand up to drilling, picking and other forms of physical attack.
• Special Angled Cut Keys: A special key cutting machine and access to Medeco-specific blanks are required to duplicate M4 keys, which are available in multiple levels of restriction to support every need.
• Master Keying Capabilities: M4 cylinders can be master keyed into a system that includes M4, M4 BiLevel, and M4 CLIQ keys and cylinders. Extremely large systems are possible.
