Anti-theft system failure can happen for a variety of reasons, such as the car battery running out, which can lead to the loss of key information, or the battery in your remote control running out. It is also possible that the immobilizer chip or car door lock may be damaged. If the anti-theft system in your car is not working, you need to find a way to temporarily disable it. You can call a technician to unlock the anti-theft system around the clock through the LiTRO mobile app.
