Key Control
Patented Key Control prevents illegal manufacturing of
keys and blanks, protects the building owner and the manufacturer,
requires special authorization of duplication, and is only
available to authorized locksmith under contract.
High security locks achieve drill resistance by using hardened
steel inserts, which is the cylinder core, stainless steel
pins, an armor shield, which is the cylinder body, and hardened
side bars.
High security cylinders use several special pins. They are
“mushroom pins” which create a false shear line,
serrated pins, beveled pins, and interlocking pins. There
are also, sidebar or side pines, and multiple locking points,
all making high security locks achieve pick resistance.
A cylinder and key system is deemed high security because
of patented key control, millions of possible combinations
and UL437 listing.
UL437 listing is when the locks are subjected to a variety
of industry testes to see if the lock resists physical attacks
such as, endurance test, attack resistance test, impression
test, picking test, forcing test, drilling test, prying
test, pulling test, driving test, and a salt spray corrosion
test.
A high security system has 22 million combinations while
standard security systems have 15, 000 usable combinations.
