ー装置。 In a keyless entry device that controls opening or closing of a door or trunk of a vehicle by sending electromagnetic waves from a transmitter outside the vehicle to a receiver on the vehicle side, the transmitter sends electromagnetic waves with a single switch operation, and On the receiver side, the carrier wave is received by a door antenna whose reception area covers the entire circumference of the vehicle and a trunk antenna whose reception area is limited to the vicinity of the trunk, and the door antenna receives a reception output of a predetermined level or higher. If the trunk antenna has a receiving output of a predetermined level or higher, the lock of the trunk is controlled, and if only the door antenna has a receiving output of a predetermined level or higher, the lock of the door is controlled. A keyless entry device that is characterized by:
