Why is the car's anti-theft system locked and unable to start the engine?

[BradyRose]

The reason why the car's anti-theft system is locked and unable to start may be: the vehicle is equipped with an engine electronic anti-theft system, which prevents the car from starting without a chip key. In such cases, you need to call a tow truck and can only have it handled at a 4S shop. Extended content: 1. A typical car anti-theft system contains an integrated chip with some switch gates. When an external trigger voltage is applied, the switch gates open and output a positive voltage to the drive circuit, thereby activating the actuator and alarm circuit. 2. The radio remote control is an important component of the anti-theft system, which uses radio signals to control various mechanisms remotely. 3. After these signals are received by the remote receiving device, they can command or drive other corresponding mechanical or electronic devices to perform various operations, such as closing circuits, moving handles, starting motors, and then these mechanical devices carry out the required operations.
