Introduction to the anti-theft system: The vehicle anti-theft system is designed to prevent the theft of the car itself or items inside the car. It consists of an electronically controlled remote or key, electronic control circuits, alarm devices, and actuators.

The technology has progressed from simple mechanical key anti-theft to electronic anti-theft and biometric electronic anti-theft. The electronic anti-theft system mainly consists of an electronically controlled remote or key, electronic control circuits, alarm devices, and actuators.
