<p>Owning a mechanical key alone does not allow knowing whether an automobile, dwelling, etc. is locked or unlocked. Furthermore, if a plurality of keys are owned, it is difficult to identify at a glance a key for a particular object. Furthermore, when a toll parking is used, a parking time has been estimated by taking notes on the time when the automobile is parked, which has caused a laborious work. Furthermore, even if an on-vehicle GPS unit is mounted, it has been necessary to take notes on map information of a surrounding area before going out of the automobile. Accordingly, the present invention provides a key with display capability that allows information relating to an object to be grasped even from a location remote from the object. Display means for displaying an image and receiving means for receiving information from an object that requires a key are provided, and information relating to the object is received from the object and then displayed. <IMAGE></p> |
