The invention discloses a vehicle theft prevention method, a vehicle theft prevention device and a vehicle theft prevention system, and belongs to the field of vehicle theft prevention. The vehicle theft prevention system comprises the vehicle theft prevention device arranged on a vehicle and a mobile terminal. The vehicle theft prevention method comprises the steps of judging the state of the vehicle, and considering the vehicle stays at a parking state if the vehicle stays at a static state without a person being in the vehicle; and closing a signal output port of a vehicle ECU if the vehicle stays at the parking state and a door of the vehicle is sensed to be opened; and sending alarm information that the vehicle is stolen to the mobile terminal. The vehicle theft prevention device monitors the state of the vehicle after a vehicle owner parks the vehicle and leaves, the signal output port of the vehicle ECU is closed immediately if a circumstance that the door is opened occurs, and the alarm information that the vehicle is stolen is sent to the mobile terminal. Even if a thief possesses a vehicle key of the owner, the vehicle cannot be started, thereby effectively ensuring the safety of automobiles.
