摘要: An electronic key system (3) that performs ID verification communication to verify an of (1). The is started by transmission a wireless signal from vehicle (2) and performed between the determines location (1) in accordance with received strength radio wave used for communication. A measurement circuit (17, 18, 19) measures first (B1), which when received, second (B2), during vacant time (Tw) performing control unit (11c, 11d) controls operation result (D) strengths (B1, B2).
