Patent abstract
A vehicle remote-operation apparatus is provided which transmits a regular authentication request signal from a vehicle-outside antenna and simultaneously transmits an interference wave for negating this authentication request signal from a vehicle-inside antenna, so that the communicable range can be limited between a radio portable unit allocated an identification code unique to a vehicle and the vehicle-outside antenna. Thereby, authentication communication is established only for a regular communication request.
