With the development of auto electrical technology, electrical anti-theft technology is
adopted on auto; thereinto electronic lock is very popular.
Generally   speaking,   electronic   lock   divides   into   control   part   and   execution   part   in
accordance   with   structure.   Control   part   is   composed   of:   input   unit,   memory,   coding,
discrimination, driver, display, alarm, safety unit and etc. The coding and discrimination unit are
the key for the whole control part. Discrimination circuit is for comparing the memory code to the
coding. When the two are the same, discrimination circuit send electronic signal to driver and
display circuit.    Execution part is usually a relay, which controls the ignition circuit with opening
or closing the contact points.
Electronic lock, according to shape, also divides into electronic-key-lock, keypad- electronic
lock, touch electronic lock, and etc. Now electronic-key-lock is usually used. This type has
built-in CMOS chip to communicate with main control circuit by light, electricity, magnetism and
