A car door lock for locking elevator car doors when the elevator car is in transit and/or outside the door zone includes a solenoid activated lever that pushes a lock arm to open. The solenoid is activated in two phases to reduce associated noise. The car door lock includes an operator switch which signals the door controller that the door lock is opened and the elevator car door is free to be opened. The car door also includes a safety switch which signals the door controller that the elevator car door lock is closed.
