Marks USA patented HI-SECURITY™ cylinders offer a secondary mechanical locking mechanism that creates resistance to bump and picking attacks. In addition, the design supports a corresponding configuration on the key blank called a “security wave” (shown below) that supports prevention of unauthorized duplication of keys. The locking principal is adaptable to standard cylinders and large and small format interchangeable cores. Marks USA HI-SECURITY™ keyways and security waves are of proprietary origination. The distribution of key blanks is factory controlled. Multiple keyways and security codes are available. Assignment is by geographic or customer category type. The Marks USA HI-SECURITY™ pick and bump resistance features are designed with added security in mind for cylinders, cores and key blanks. In addition, patents provide legal protection for patent infringement against those who attempt to produce or manufacture key blanks or cylinders. Marks USA will aggressively defend its patent rights!
