QQ3 of Chery has a triple anti-theft locking function. First, without closing the window when getting off the car, just directly lock the car and the four windows will be automatically closed and locked; secondly, when the four windows are locked, the engine will also be locked to realize the anti-theft function of the engine; thirdly, after being locked, the car is on alert and all the small lamps may flash and the horn may sound when the system is triggered. If someone wants to enter the car with inappropriate means, he will not be able to start it even with the key.
