Abstract

A smart entry system includes a vehicle-side unit and a plurality of portable devices. Each of the portable devices has a discrimination code different from each other. When a first portable device is locked in a vehicle compartment, the discrimination code of the first portable device is stored in the vehicle-side unit. When the vehicle is parked in a state where all of the doors are locked, the vehicle-side unit transmits a request signal to an exterior communication area provided at an outside of the vehicle, and when the vehicle-side unit receives a response signal from a second portable device and the discrimination code of the second portable device is different from the discrimination code of the first portable device stored in the vehicle-side unit, the vehicle-side unit permits an unlock of the doors of the vehicle.
