Zusammenfassung:The invention relates to a door-locking device having an inside door-handle element which can be moved from a closed position into an open position by virtue of an inside door handle being actuated. Also provided is an outside door-handle element which can be moved from a closed position into an open position by virtue of an outside door handle being actuated. A driver element can be coupled in a form-fitting manner to the inside door-handle element and the outside door-handle element by a coupling 3 and can be moved from an uncoupled closed position into a coupled open position by the inside door-handle element and the outside door-handle element. By means of the driver element, in the coupled state, a catch of a door lock can be actuated, it being the case that the coupling 3 can be moved counter to a spring force from its coupled position into its uncoupled position by an uncoupling element. An authorization signal 7 can be directed in a contactless manner to a control unit 5 by a mobile authorization unit 6, and the outside door handle is assigned a switch 8 by means of which, when the actuation of the outside door handle begins, a signal can be produced and directed to the control unit 5 and, when this signal and the authorization signal 7 are present, a drive can be activated by the control unit 5 such that the uncoupling element can be driven to move from its uncoupled position into its coupled position by the drive.
