Abstract
A plug assembly for a lock includes a generally cylindrical plug body that defines a keyway and a generally cylindrical plug housing that rotatably receives the plug body. A plurality of blocking members are housed in the plug body and are movable into the keyway upon rotation of the plug body relative to the plug housing to obstruct the keyway. A key can be provided that is positionable into the keyway, and the blade of the key defines receptacles for receiving the blocking members when the plug body is rotated so that the lock can be unlocked. However, the blocking members prevent rotation of the plug body when a picking tool or unauthorized key is inserted in the keyway since either the blocking members cannot move into the keyway and remain engaged to the plug housing due to the object in the keyway, or obstruct the keyway and prevent insertion of the picking tool.
