Features: Alarm Mode and Anti-Hijacking Function Can Be Selected: When the car-installed system does not detect the induction card, the car cannot be started even if the car door is pried open and forcibly started, thus achieving the anti-theft purpose. When the car is driving, if the induction card is taken away from the car, the car will automatically flame out after 1 minute, thus achieving the anti-hijacking purpose. User-friendly Design: The anti-hijacking alarm system has a detection range of 2 meters, with an emergency release function, providing a more convenient user experience. Large-Capacity Battery: The immobilizer uses a large-capacity CR2032 battery in its induction card, ensuring long-lasting performance. You won't have to constantly replace the battery. When the internal battery voltage of the induction card is too low, a beep alarm will sound after starting the vehicle. Strong compatibility & Simple Installation: The engine immobilizer is suitable for any 12V car. (It can be installed in vehicles that have already installed anti-theft alarms) It has a small size, simple wiring installation, and strong concealment.
