Method for authorizing the use of a motor vehicle, in particular a two-wheeled or four-wheeled motor vehicle, which has at least one first and one second antenna, wherein the first antenna and the second antenna are spatially remote from one another, by way of a portable identification transmitter that has an identification transmitter antenna, having the following steps: - the first vehicle antenna emits a first signal that is received by the identification transmitter antenna, - the identification transmitter establishes at least one of the spatial components of the first electromagnetic field of the received first signal, in particular using an angle-resolving magnetic field sensor, - the second vehicle antenna emits a second signal that is received by the identification transmitter antenna, - the identification transmitter establishes at least one of the spatial components of the second electromagnetic field of the received second signal, in particular using the angle-resolving magnetic field sensor, - the identification transmitter transmits the established at least one spatial component of the first electromagnetic field of the received first signal and the established at least one spatial component of the second electromagnetic field of the received second signal or first corresponding data to the vehicle, - a computer, in particular a computer in the vehicle, establishes the angle at least between the established spatial component of the first electromagnetic field of the received first signal and the established spatial component of the second electromagnetic field of the received second signal, and - the vehicle provides a first authorization signal for authorizing the use of the motor vehicle only when the established angle exceeds a predetermined threshold value, characterized in that the identification transmitter is provided with a motion sensor, the motion sensor establishes whether it or whether the identification transmitter is being moved, and the identification transmitter transmits a second authorization signal for authorizing the use of the motor vehicle to the motor vehicle only when the motion sensor establishes a movement of the identification transmitter, wherein the first corresponding data may constitute the second authorization signal. - the first vehicle antenna emits a first signal that is received by the identification transmitter antenna, - the identification transmitter establishes at least one of the spatial components of the first electromagnetic field of the received first signal, in particular using an angle-resolving magnetic field sensor, - the second vehicle antenna emits a second signal that is received by the identification transmitter antenna, - the identification transmitter establishes at least one of the spatial components of the second electromagnetic field of the received second signal, in particular using the angle-resolving magnetic field sensor, - the identification transmitter transmits the established at least one spatial component of the first electromagnetic field of the received first signal and the established at least one spatial component of the second electromagnetic field of the received second signal or first corresponding data to the vehicle, - a computer, in particular a computer in the vehicle, establishes the angle at least between the established spatial component of the first electromagnetic field of the received first signal and the established spatial component of the second electromagnetic field of the received second signal, and - the vehicle provides a first authorization signal for authorizing the use of the motor vehicle only when the established angle exceeds a predetermined threshold value,
