PROBLEM TO BE SOLVED: To provide a hologram ID key system allowing key operation by the collation coincidence of hologram ID difficult to duplicate, at a door of a house or a hotel, or a door of a safe or a locker, or an ignition key or the like of an automobile and furthermore allowing control on who locked or unlocked when. SOLUTION: In this system, a hologram ID key wherein holograms comprising circular bar codes having ID information consisting of a plurality of bits are transferred to at least one or more parts on the surface of the key, is used, and the ID information is detected from the holograms transferred to the key, by hologram detecting parts disposed at a face opposed to the holograms within a keyhole of an electric lock for inserting the hologram ID key. The detected ID information is compared with ID information preset to a control part of the electric lock, and only when the ID information is coincident, key operation can be performed.
