The pottery and porcelain that every get on the key bead the package look that has code of corresponding and different electron matchs. When ignition key inserts ignition switch, the electric contact inside key canister undertakes metrical to the resistor of the key, send message to afore-mentioned component. If with the block value of bead of pottery and porcelain is same, can launch a car, cannot ignite otherwise start.

The characteristic that lock of biology feature electron locks up this kind is the human body biology such as sound, dactylogram the feature regards a password as the input, undertake discriminating by the computer, control opens a lock. Because the intelligence of lock of electron of type of this biology feature changes rate,comparative tall. This also is the trend of a kind of development that electron of car guard against theft locks up.
