Abstract
A vehicle-mounted unit includes a controller which changes a setting of a search method of portable units between a simple search method which is based on sending/receiving of simple search signals and simple response signals and an individual search method which is based on sending/receiving of normal search signals and normal response signals, and an ID-storage part which updates and stores the ID of the portable unit authenticated at a latest time as the latest authenticated ID. When the latest authenticated ID is stored in the ID-storage part, the controller searches the portable unit having the latest authenticated ID by priority and by the individual search method.
