What is Engine Electronic Anti-Theft?

[HenryRose]

Engine electronic anti-theft is a security system installed for the engine. Its principle is: the car ignition key contains an electronic chip, each chip has a fixed ID. Only when the key chip's ID matches the ID on the engine side can the car be started. If they don't match, the car will immediately automatically cut off the circuit, preventing the engine from starting. Its function is: the electronic anti-theft ECU communicates with the key via radio frequency to verify correctness and thus obtain the right to start the engine. Causes of engine electronic anti-theft system failure: 1. Whether the key matches the chip's key; 2. Whether the anti-theft converter inside the key is intact; 3. Whether the ignition coil is intact.
