The method also includes determining an antenna of the vehicle depending on the movement direction of the recognized person, and increasing a maximum transmission power of the determined antenna of the vehicle towards the position of the recognized person. The method further includes identifying a vehicle key of the person using the increased maximum transmission power of the determined antenna.
