A wheel chock with a magnet actuated to lock and unlock with an underlying steel plate is anchored to the adjacent pavement. A proximity sensor senses the presence or absence of the underlying steel plate to ensure proper placement and magnetic engagement. Wireless transmission/receiver communications between the wheel chock, magnet, proximity sensor and a loading dock operations console provides remote sensing and control of the locking and unlocking operation. An electro magnet or a manually actuated permanent magnet can be used. The electromagnet can receive electric power from a battery or can be hard wired to the adjacent loading dock. The permanent magnet option may include wireless communication and a battery to be physically independent of the loading dock.
