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. An authorization signal can be directed in a contact less manner to a control unit by a mobile authorization unit, and the outside door handle is assigned a switch by which, when the actuation of the outside door handle begins, a signal can be produced and directed to the control unit and when this signal and the authorization signal are present a drive can be activated by the control unit such that an uncoupling element can be driven to move from its uncoupled position into its coupled position by the drive.
