BiLevel /Other/Medeco/Products/M4-BiLevel-Web-Page-Header.png The Medeco 4 (M4) key system enables facilities to have a combination of high-security cylinders and cost-efficient cylinders all on the same key system, which is the perfect solution for managing key control. It provides patented key control and two levels of protection to ensure the right level of security for each opening in your facility. M4 High Security cylinders are UL 437 listed, giving protection against physical attacks such as picking, drilling, and bumping. M4 BiLevel cylinders offer affordable key control through patent-pending keys, without enhanced UL437 attack resistance, which ensures you are not paying for high-security features that may not be needed for certain openings. Additionally, keys are only available from the authorized original dealer. Technology built into M4 keys includes a movable key element that inhibits duplication by 3D printers, plus a slider that interacts with a sidebar for extra protection. Medeco BiLevel cylinders can also tie in with other high security (UL437) Medeco mechanical intelligent key systems for limited master keying purposes. Patented Key Control - Protects against unauthorized duplication of your keys. Uses Existing Hardware - Can be masterkeyed into a system containing Medeco BiLevel, Medeco 4 Mechanical, Medeco³ Mechanical; as well as Medeco³ CLIQ Intelligent Key Systems. Medeco³ and Medeco 4 cylinders are available in a wide variety of formats, retrofitting most hardware on the market today. Can Be Masterkeyed - Medeco BiLevel cylinders can also tie in with other high security (UL437) Medeco mechanical intelligent key systems for limited master keying purposes. Special Angle Cut Keys - Requires a special key cutting machine and access to Medeco specific blanks, available in a variety of restrictions to support every need. Picking & Bump Protection - Medeco BiLevel cylinders use a sidebar that prevents the key from rotating until it is elevated, rotated and aligned in the correct position.
