Abstract

The car sharing system includes a car share device and an encryption code updating unit. The car share device is configured to perform wireless communicate with a mobile terminal that is operable as a vehicle key. The encryption code updating unit updates a first encryption code, which was used during a previous connection of the mobile terminal and the car share device, to a second encryption code, which differs from the first encryption code, when the mobile terminal and the car share device are reconnected.
