A method for authorizing access to a motor vehicle involves monitoring a decrease in the signal strength of the second communication connection, while the identification transmitter is moved away from the motor vehicle, such that the spacing between the motor vehicle and the identification transmitter increase. The current signal strength of the second communication connection is stored as a reference value as soon as the first communication connection between the motor vehicle and the identification transmitter is deactivated/interrupted. The first communication connection is reactivated as soon as the signal strength of the second communication connection exceeds the stored reference value due to the decreasing spacing between the motor vehicle and identification transmitter when the identification transmitter is moved towards the motor vehicle again.
