A high security lock includes a lock cylinder and a plug within the cylinder. The plug is rotatable about an imaginary axis and defines a keyway having two opposing keyway sides extending longitudinally within the plug. The keyway sides taper with respect to an imaginary plane dividing the keyway. One or more paracentric keyway ribs protrude from the keyway sides. The apparatus further includes a high security key comprising a bow region, a key guide region, and a key blade which has two opposing key sides which taper with respect to an imaginary line dividing the key blade. The key blade has key grooves corresponding to the keyway ribs. |
