A flashing red lock on the Corolla dashboard is the anti-theft system status light, indicating that the vehicle's engine has entered the anti-theft mode. Below are some additional details: 1. Introduction: Car anti-theft devices are high-tech security products that integrate GSM network digital mobile communication technology and GPS satellite positioning technology. They represent the latest generation of car anti-theft products, succeeding one-way and two-way anti-theft devices. By utilizing mobile communication networks, they completely overcome the distance limitations and vulnerability to hacking that traditional anti-theft devices face. 2. Working Principle: A typical electronic car anti-theft device contains an integrated chip with internal switches. When an external trigger voltage is applied, these switches open and output a positive voltage to the drive circuit, activating the actuator and alarm circuit.
