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.
