Zusammenfassung:An electronic key system (3) includes transmission devices (22, 23) arranged in a vehicle (2). Each transmission device (22, 23) forms a communication area (Ado;Adi, Apo;Api) and transmits an inquiry signal (Swk). Each transmission device (22, 23) forms an exterior verification communication area (Ado; Apo) when determining whether or not the electronic key (1) is located outside the vehicle (2) and an interior verification communication area (Adi; Api) when determining whether or not the electronic key (1) is located inside the vehicle (2). An area setting unit (21 b) sets the exterior verification communication area (Ado; Apo) with a size that differs from that of the interior verification communication area (Adi; Api).
