With the constructions ofcitiesand countryside widely developing,road extends inalldirections and reaches almost ’living standard iSenhanced day byday,more and more salary willbeable tobuy an automobile 。 e an essential toolinstead offoot. The system ofguarding against theft introduced inthedissertation is aproduction ofmachine and electron integration with high intellectualand high machine structure system isdeveloped by ourselves and we have independent knowledge right for themachine the Keeloq technology can protect automobiles from being stolen more the other will change the condition ofChinese system ofguarding against theftcontrolled by other developed automobile’S parts manufacturers.
