A free-wheeling lock mechanism for a cylindrical door lock includes inner and outer spindles directly connected to corresponding inner and outer lever handles, a latch retractor located between the spindles and a cylindrical outer cam located within the outer spindle. The outer cam has an ear on its perimeter that moves from a forward to a rearward position as the outer cam is rotated to operate the latch retractor. A cylindrical locking plug is located within the outer cam and has an outwardly projecting finger that connects and disconnects the outer cam from the outer spindle to lock and unlock the mechanism as the locking plug slides axially relative to the outer cam. In the unlocked position the finger projects outwardly through a slot in the outer cam into a longitudinally oriented portion of a T-shaped slot in the spindle. In the locked position the finger projects outwardly through the outer cam slot into a circumferential portion of the spindle slot.
