What does it mean when an Alto car displays a car with a lock?

[VanJourney]

When an Alto car displays a car with a lock, it indicates that the car's anti-theft lock is engaged. Categories: Based on technical principles, car anti-theft locks can be broadly classified into mechanical anti-theft locks, electronic anti-theft alarm locks, and networked anti-theft (positioning, tracking) systems. Car anti-theft locks include electronic car anti-theft locks, network car anti-theft locks, fuel line locks, clutch and brake anti-theft locks, wheel anti-theft locks, gear shift locks, steering wheel locks, and car anti-theft magnetic plates. Principle: When the ignition switch is turned on, the key transponder and the anti-theft controller exchange initial information. If the identification codes between the key and the chip do not match, the anti-theft controller will not continue to communicate with the ECU, keeping the ignition system and fuel injection system circuits in an open state, preventing the engine from starting.
