The invention discloses an automotive engine burglary prevention deblocking method and system. The automotive engine burglary prevention deblocking method comprises the steps of judging that whether a burglary prevention controller receives a deblocking authentication request sent by a transducer or not in a preset time after an auto ignition signal is received, and if the controller receives the request, performing deblocking according to the received deblocking authentication request, if the request is not received by the controller, then switching to a manual deblocking mode; the manual deblocking comprises the steps of acquiring a manual deblocking code from a preset manual code input port; judging that whether the manual deblocking code is identical with a preset deblocking code or not, and if yes, performing deblocking on an engine burglary prevention system. By adopting the automotive engine burglary prevention deblocking method and system, the problems of unable deblocking due to a fault of the transducer or a burglary prevention coil existing in the prior art are effectively solved, and a failure rate of the engine burglary prevention system is greatly reduced.
