Abstract
In an electronic key system, at least one of an electronic key and a vehicle side device includes a communication device, a storage unit, and a discrimination unit. The storage unit acquires a location information from a location information terminal through the communication device, and stores information on an unlocking permissible range based on the location information when a vehicle door is locked. The discrimination unit acquires the location information from the location information terminal through the communication device, and discriminates whether the acquired location information falls within the unlocking permissible range, or not, when the wireless communication is performed between the electronic key and the vehicle side device because the vehicle door is unlocked. When the discrimination unit discriminates that the position of the electronic key does not fall within the unlocking permissible range, the vehicle door is not unlocked.
