Common pin tumbler cylinders may be compromised by picking, drilling or key bumping. For applications where a greater security level is required, we suggest using pick/drill resistant cylinders with multiple pin planes such as those with side-bars. Marks USA HI-SECURITY™ Cylinders are constructed with sidebars and are drill, pick and bump resistant.
