  • Patent number: 7696858
    Abstract: A door lock interface system includes a stationary controller that is mounted to a support surface at an interior of a building. A portable controller is in wireless communication with the stationary controller. An elongated and rectilinear bolt is positioned through a slot of a door and is spaced from the stationary and portable controllers. A mechanism is included for automatically retracting and extending the bolt along a parallel and horizontal path. A mechanism is included for bypassing the automatic retracting and extending mechanism such that the user can manually retract and extend the bolt. A security panel is affixed to one side of the door and covers one door cavity, prohibiting unauthorized access thereto. The security panel is provided with annular openings, allowing a door handle and a deadbolt housing to be connected to the door while maintaining the automatic extending and retracting mechanism hidden from the environment.
