Abstract
Provided is an electronic key system for a vehicle. The electronic key system for a vehicle includes an in-vehicle device and a portable device and performs a predetermined control process on a vehicle on the basis of verification successfully made between the in-vehicle device and the portable device. When receiving a verification signal, the portable device transmits a response signal in accordance with the verification signal. When an operation detection unit detects a user operation, the portable device transmits an instruction signal for controlling a state of locking of a door of the vehicle. An output level of the response signal from the portable device is lower than an output level of the instruction signal.
