The invention provides an automobile anti-theft control method and system, an automobile body controller and an engine control unit. The automobile anti-theft control method comprises the steps of receiving an anti-theft removing signal and an ignition gear signal sent by a remote control key; identifying the remote control key, and sending an identification request to the engine control unit which is in an anti-theft state; receiving a first random code for identification, which is sent by the engine control unit, and sending a first identification response message to the engine control unit after the identification of the remote control key is passed; and receiving a first identification passing confirmation message returned by the engine control unit after the identification is passed and the anti-theft state is switched into an anti-theft identification passing state, and recording the state of the engine control unit to be the anti-theft identification passing state. By the dual identification between the remote control key and the engine control unit, the anti-theft performance of an automobile is improved, thereby guaranteeing that a vehicle cannot be started when an illegal person steals the vehicle.
