Abstract

The system allows locating an enabling component of a motor vehicle. The enabling component, provided with a chip, is for example a smart card or an electronic key. The enabling component is addressed with a search signal from a transmitter fixed to the vehicle. The enabling component responds with an indicating signal. The indicating signal may be an audible signal emitted by the enabling component itself and/or the location information can be indicated by an indicator device fixed to the vehicle.
