A method for authenticating a radio key for a vehicle involving determining a distance between the radio key and the vehicle and authenticating the radio key. A character string generated by the radio key is transmitted to the vehicle to determine the distance. The character string is generated independently of an item of information transmitted by the vehicle, and the authentication is based on the character string.
