[Object] A keyless entry apparatus capable of reducing erroneous control by reliably confirming start-up of a portable device even when a user carries an information device is provided. [Solution] A vehicle-side device that is provided on the vehicle side and transmits a signal at a first frequency, and a portable device that is able to be carried by a user and transmits a signal at a second frequency are included. The portable device transmits a signal of data based on a reception intensity of a measurement signal transmitted from the vehicle-side device, and the vehicle-side device performs predetermined control on the basis of the data based on the reception intensity of the measurement signal transmitted from the portable device. The vehicle-side device transmits a start-up signal to the portable device, the portable device transmits a request signal or a signaling signal to the vehicle-side device in each predetermined time when receiving the start-up signal, and the vehicle-side device transmits the measurement signal to the portable device each time the vehicle-side device receives the request signal or the signaling signal. |
