The invention discloses a vehicle engine electronic antitheft system and an antitheft method thereof. A key converter is arranged in a vehicle key; a reader coil is mounted on a vehicle ignition key cylinder, and is connected with an antitheft control unit; an antitheft indicator light is connected with the antitheft control unit; the antitheft control unit is connected with a vehicle engine control unit; the key converter and the antitheft control unit mutually transfer signals and energy; the reader coil transfers signals and energy between the antitheft control unit and the key converter; and the antitheft control unit operates, communicates, controls and drives. The system has the following advantages: 1) enciphered data is transmitted through wires; and signals are in wireless transmission; 2) the system only can be cracked by disassembling all engine control units and then recovering; 3) the engine control units only can work by passing through the verification; the antitheft control unit can send signals to the engine control units; and the engine control units can work to crack the system; and 4) the system is safe and reliable, and cannot be cracked and disassembled by mounting persons under the condition of no keys.
