Abstract

A smart key system (1) includes a vehicle-side communication device (12) installed in a vehicle (2) and a smart key (11) carried by a driver (3). The vehicle-side communication device and the smart key are wirelessly connected. The system includes: a main switch (13) accepts activation of the vehicle-side communication device; a start switch (14) accepts start of a prime mover (16) of the vehicle; and a controller (15) authenticates a response signal from the smart key. When the main switch is turned ON, an authentication process is started in the controller, and a periodic authentication is performed periodically after an initial authentication is performed. When the start switch is turned ON within a certain period after successful authentication, the controller starts the prime mover, and when the start switch is still OFF even after a certain period elapses since successful authentication, the controller resets a state of the successful authentication.
