Features: Selectable alarm mode and anti-hijacking function: When the in-vehicle system does not detect the proximity card, the car cannot be started even if the door is opened and forced to start, thus achieving the purpose of preventing theft. When the car is driving, if the induction card is taken away from the car, the car will automatically turn off after 1 minute, thus achieving the purpose of preventing hijacking. Humanized design: The anti-hijacking alarm system has a detection range of 2 meters and has an emergency release function, providing a more convenient user experience. Large-capacity battery: The anti-theft device uses a large-capacity CR2032 battery in the proximity card to ensure long-lasting performance. You don't have to replace the batteries often. When the battery voltage inside the proximity card is too low, a buzzer alarm will sound after starting the vehicle. Strong compatibility and easy installation: the engine immobilizer is suitable for any 12V car. (Can be installed on vehicles with anti-theft alarms installed) Small size, simple wiring and installation, and strong concealment.
