A vehicle, comprising a locking/unlocking system, wherein: - the locking/unlocking system is configured to lock/unlock the vehicle, - the locking/unlocking system comprises: - a power reception device that is provided in the vehicle and has a vehicle coil which is configured to receive power at a first frequency from a ground coil provided on a ground in a non-contact manner during a power reception operation; - an operation switch that is provided in the vehicle and that is configured to output an operation signal in response to a user operation; - a locking/unlocking controller that is configured to conduct wireless communication at a second frequency close to the first frequency with a key device located within a predetermined distance in response to an input of the operation signal and to lock/unlock a lock provided in the vehicle in response to successful wireless communication with the key device; - a signal determining part that is configured to receive the operation signal from the operation switch and to output the operation signal to the locking/unlocking controller when the signal determining part is electrically connected to the operation switch; and - a wiring switch configured to be switched by a power reception controller based on whether the power reception device is during the power reception operation, - the wiring switch is configured to electrically connect the operation switch and the locking/unlocking controller when the power reception device is not in the power reception operation, - the wiring switch is configured to electrically connect the operation switch and the signal determining part and to electrically connect the signal determining part and the locking/unlocking controller when the power reception device is in the power reception operation, - the signal determining part is configured to suppress the power reception operation in response to an input of the operation signal into the signal determining part, and - the signal determining part is configured to store the input operation signal and to output the stored operation signal to the locking/unlocking controller in response to completion of suppression of the power reception operation. - the locking/unlocking system is configured to lock/unlock the vehicle, - the locking/unlocking system comprises: - a power reception device that is provided in the vehicle and has a vehicle coil which is configured to receive power at a first frequency from a ground coil provided on a ground in a non-contact manner during a power reception operation;
