To provide a vehicle control device capable of preventing an oil filler from being brought into an unlocked state unnecessarily and improving security even if the detection range of a portable machine by an in-vehicle machine is wide.

The vehicle control device has a keyless function for performing the locking and unlocking of a door without key operation through certification by the portable machine 2 and the in-vehicle machine via communication and for releasing the operation restriction of the vehicle through certification by the portable machine 2 and the in-vehicle machine via communication also inside a cabin. When determining that the portable machine 2 is positioned near the oil filler by the keyless function, the in-vehicle machine starts the operation of a fuel lid LF antenna provided in the vicinity of a fuel lid, and performs certification through communication by the fuel lid LF antenna to open or unlock the fuel lid.
