Abstract: Car-used burglarproof lock capable of controlling power on/off of the car. By means of unlocking/locking the lock core of the burglarproof lock, a remote controlling unit hidden in the burglarproof lock is controlled. By means of remote controlling unit, a receiving controlling unit disposed in a hidden place of the car is controlled to identify and go into standby cut off state (or immediate cut off state) or go into power on state for discharging standby cut off state (or immediate cut off state). Accordingly, the car-used burglarproof lock has both mechanical burglarproof effect and electronic standby cut off (or immediate cut off) burglarproof effect.
