What is anti-theft mode and how does it work in my car?
Anti-theft mode, also known as immobilizer mode, is a security feature designed to prevent car theft by disabling the engine and other essential systems. When your car is stuck in anti-theft mode, it means the immobilizer system has been triggered, and your car’s computer has blocked the engine from starting. This can happen due to various reasons such as a dead battery, faulty sensor, or incorrect key usage. The anti-theft system is usually linked to the car’s central computer and uses a transponder chip in the key fob to verify the authenticity of the key.
The immobilizer system works by using a complex algorithm to match the code from the key fob with the one stored in the car’s computer. If the codes do not match, the system will disable the engine and prevent the car from starting. In some cases, the anti-theft system may also trigger an alarm or flash the car’s lights to deter potential thieves. Understanding how the anti-theft mode works is crucial to resolving the issue when your car gets stuck in this mode. It is essential to consult your car’s manual or contact a professional mechanic to diagnose and fix the problem.
