The rotor is moveable between at least a locked position and an unlocked position by movement of the handle. The sash lock mechanism also includes a locking mechanism that contains a pivotable member pivotably connected to th e housing. The pivotable member is pivotable between a first position and a second position . When the rotor is in the locked position and the pivotable member is in the first position, th e pivotable member confronts the rotor to prevent movement of the rotor to the unlocked positio n. When the pivotable member is in the second position, the pivotable member does not prevent movement of the rotor.
