A locking apparatus for use on a handle operable to be gripped by a user's hand. The apparatus includes a moveable actuator operable to be moved by a portion of a user's hand when gripping the handle. A first moveable blocking member is connected to the handle and is operable to be moved into an enabling position in which movement of the movable actuator is enabled and is operable to be moved into a blocking position in which movement of the actuator is blocked by the blocking member interfering with movement of the actuator. A first mounted magnet is connected to the first blocking member and is disposed in a position on the handle such that at least one of the user's fingers will be adjacent the first mounted magnet when the handle is gripped. The first mounted magnet is operable to cooperate with a first adjacent magnet placed adjacent the first mounted magnet to move the first blocking member between the blocking and enabling positions. A method of unlocking an actuator on a handle includes gripping the handle such that an adjacent magnet on a finger ring worn by the user is placed adjacent a mounted magnet on the handle, attracting the mounted magnet with the adjacent magnet thereby moving a first blocking member out of the path of an actuator on the handle and squeezing the handle and the actuator to move the actuator relative to the handle.
