The performance of an action for a transportation vehicle, wherein a relay attack is prevented. In response to a transmission of a first radio signal at a first frequency, on the one hand, a second radio signal at a second frequency is received from an ID transponder authorized for the transportation vehicle and, on the other hand, a further radio signal at the first frequency is received. The action is performed for the transportation vehicle only in response to the second radio signal originating from an ID transponder authorized for the transportation vehicle and only in response to the signal strength of the further radio signal lying below a predefined signal strength threshold.
