1. Car engine anti-theft device. 2. Automatic induction relay replacement without installation; installation is not easily identifiable. 3. No need to operate in automatic induction mode; can switch between manual and anti-theft modes. 4. Does not damage car wiring; quick and easy installation. 5. Automatically cuts off fuel after engine shutdown; automatically opens fuel line when approaching the vehicle; sensing distance approximately 15 meters. <br><br>Utilizes anti-shielding and anti-interference technology; stable chip. Compatible only with 12V gasoline vehicles. Features: Unit relay working principle: 1. First engine start: The unit begins scanning the sensor ID password. If a match is successful within 25 seconds, the vehicle can start successfully. If the scan fails, the fuel circuit will be cut off after 25 seconds, and the engine will stop running. 2. Second engine start: The device shortens the scanning time to 20 seconds. 3. Third engine start: The device shortens the scanning time to 10 seconds. 4. Fourth engine start: The device cannot scan the correct password, indicating that the vehicle has been illegally started. Regardless of the number of starts, the device can detect the correct password before driving the vehicle. 5. In hidden lock mode, the drive unit no longer scans the sensor ID; it needs to re-sensor the sensor after powering off. Remote control: Static current approximately 0mA, operating current 5mA. Battery specifications: CR2032 unit. Relay: Operating current approximately 20mA. Color: Black. Material: ABS. Package contents: 1 * Relay 2 * Remote control.
