ABLOY® PROTEC2 keys are cut on two different
radii, disks are blocked at their position after a quarter turn
by the return bars. Return bars also scramble the disks during key
exit and hold disks at position to prevent picking and false opening.
Disc Steering System guides the key into the lock with no resistance
for less key wear. Patented and highly restricted, ABLOY®
PROTEC2 has over 1 billion useable combinations, no code is ever
repeated. ABLOY® PROTEC2 has also proven to have an incredible
resistance to physical attack and environmental situations, while
being pick proof and bump proof.
