Why doesn't the newly bought car ring when it is locked?

Ask the store to start some functions that can be opened in the driving computer. First, give your computer a new code, which can adjust the running mode of the engine and make your car more fuel efficient. Second, when the door is opened remotely, the horn rings twice. On the basis of the original car anti-theft, an upgraded version of anti-theft is added, and the car is called when the door is locked. Third, when the door is closed remotely, the horn sounds 1. Fourthly, when the vehicle speed reaches 15KM, the central door lock automatically locks the vehicle (four doors). When the key is taken out of the fire, the engine is automatically unlocked. Fifth, when the car is passively or illegally ignited, the anti-theft device of the original car is only anti-theft, but it is silent. Now, if this happens, the car horn will keep ringing. Sixth, the seat belt light is not on. I can turn on the seat belt light for you and light it for 5 seconds when it is ignited. Seventh, now the remote control is adjusted. If you press the door once, it will only open the driver's door. If you press the door twice quickly, four doors will open completely. (There are differences due to different functions)
