Cylinder and key as a secure basis A major advantage of reversible keys is that they are equipped with copy protection and can only be duplicated by authorized persons with a security card. In addition, the keys and cylinders are protected against unauthorized copying by long patent terms. The reversible key systems also offer flexible expansion options to meet the needs of a changing environment. Mechanical access control can be supplemented and combined with electronic systems to ensure even greater security.
