A method for authorizing the use of a motor vehicle, including a first antenna and a second antenna, wherein the first antenna and the second antenna are spaced apart from each other in space, by a portable identification device that has an identification device antenna. According to the method, it is determined whether the identification device is moving toward the motor vehicle, which can be determined by the identification device repeatedly identifying the field strength of the signals emitted by the motor vehicle and examining whether the field strength is increasing. Alternatively, the identification device can repeatedly identify the angle between the signals emitted by the motor vehicle and examine whether the repeatedly identified angles are increasing.
