BiLevel cylinders offer affordable key control through patent protected keys. For areas that require protection against picking, bumping, drilling, prying, or other forms of attack, UL 437 Listed Medeco³ may be added to the system.

Standard locking systems without utility patent protected keys allow anyone who gains possession of a key to easily and inexpensively make a copy. With an unauthorized duplicate key, a thief has complete access to a building, its physical and intellectual property, and the people inside. BiLevel locking systems ensure that the keys to a facility can only be duplicated by certified Medeco dealers and only with the proper authorization.

Medeco® BiLevel cylinders can tie in with other Medeco® mechanical and eCylinder products for 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, Medeco³ Mechanical; as well as Medeco³ CLIQ Intelligent Key Systems. Medeco³ cylinders are available in a wide variety of formats, retrofitting most hardware on the market today.

  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.  This feature offers protection against bumping and picking attacks.
