Abstract: An automatic window fastener for use in securing a window having a window sash and a window frame is disclosed. An illustrative window fastener may include a housing body, a lever coupled to the housing body, an actuator mechanism operatively coupled to the lever and actuatable between an unlocked position and a locked position, and a keeper mechanism. During operation, the lever can be configured to rotate and tilt outwardly away from the housing body, providing the user with a visual indicator that the window fastener is in an unlocked position. The actuator assembly can include a number of components that prevent the window fastener from being picked by an intruder. Window locking systems employing one or more window fasteners are also described herein.
