Anti-theft system locked and unable to start the engine. Below is an introduction to the issue of the anti-theft system locking the engine: Principle: It locks the car's engine, electrical circuit, and fuel system, preventing the vehicle from starting without a chipped key. The car anti-theft lock getting stuck is a common fault of the car anti-theft system. Introduction: The vehicle is equipped with an engine electronic anti-theft system, also known as a chip-type anti-theft system. When the door lock is disabled, it will trigger an alarm sound. If this happens to your car, use the key to open the driver's or passenger's door, then wait a few minutes, and the alarm will stop. Open the engine hood and locate the alarm. You can find it by referring to the car's operation manual, then turn off the alarm.
I've encountered the issue of the anti-theft system locking up and preventing the engine from starting more than once or twice. This is usually caused by a depleted key fob battery, which prevents the signal from reaching the car. Check if the battery in your car key is old and try replacing it with a new one. Another common reason is dust covering the sensors or interference from nearby sources like mobile phones. Try cleaning the sensors and keeping metal objects away. Once when I was on a business trip and couldn't start the car, using the spare key solved the problem, which reminded me to always carry a spare. If that still doesn't work, disconnecting the car battery for a few minutes can reset the system. However, if the problem persists after multiple attempts, it's best to visit a repair shop to check the circuit module. Regular inspection of the car key and maintenance of the system can prevent such troubles and ensure smooth driving.
It's quite annoying when the anti-theft system locks up and the car won't start. I've found that most cases are due to a dead key fob battery or matching errors. First try starting with the spare key - if it works, that means there's an issue with the original key. Avoid keeping keys near strong magnetic objects to prevent signal interference. Last time my car wouldn't start in the garage, I solved it by repeatedly opening and closing doors near the vehicle. Preventive measures include monthly key function tests and early battery replacement. If problems persist, it might indicate module failure or wiring aging, requiring a technician's diagnostic tool inspection. For safety, never force it when this happens to avoid engine damage.
