High-Security Locks

The high-security locks featured in these pages will meet a variety of strength, endurance and reliability challenges.  The lock cylinders have a unique telescopic pin tumbler mechanism with internal and external pins.  Both the internal and external shear lines must be aligned simultaneously for the plug to rotate.  When the top and bottom pins, and plug and body meet, a 3-dimensional shear line is formed making a nearly spherical shape.  These features, along with steel inserts, makes the cylinder pick-resistant and drill-resistant for high-security requirements.  When master keyed, additional side pins or back pins can be incorporated.


High-security locks feature (a) patented key control, (b) a UL 437 listing, and (c) millions of possible keying combinations.  In combination, these features prevent the illegal manufacturing of keys and key blanks, because duplication of keys requires special authorization, and key manufacturing equipment is limited to authorized professional locksmiths approved by the lock’s manufacturer.


These high-security locks exceed the construction and performance criteria (i.e., strength, aging/stress, moisture absorption, picking, forcing, drilling, prying, pulling, and salt spray corrosion) required to secure a UL 437 listing, and have also passed the stringent tests presented by such organizations as CEN, VDS, SKJ, and many more.
