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.
