PURPOSE: An apparatus for preventing vehicle burglary is provided to prevent unlocking of a door due to an external noise, an error signal from an electronic wave or an erroneous operation of an electronic control unit by operating a relay unit mounted in an immobilizer and connecting an electronic control unit to an execution unit by an electric signal, thereby releasing locking status of the door by the execution unit. CONSTITUTION: An apparatus for preventing vehicle burglary includes an electronic control unit(10) perceiving an ignition starting operation state to read secret code data and outputting a control signal, an immobilizer(20) for receiving an output signal of the electronic control unit and comparing and analyzing the secret code data, and an execution unit(30) for releasing a door-lock state of the door from a control signal inputted through the immobilizer, wherein a relay is mounted in the immobilizer for operating the execution unit to release the locking state of the door only when the signal outputted from the electronic control unit is inputted by a predetermined time before the relay is driven for the input or output of the control signals via the immobilizer between the electronic control unit and the execution unit. |
