What to Do When the Anti-Theft System is Locked?
2 Answers
There are three methods to resolve the issue when the anti-theft system is locked: 1. Turn the vehicle's power on and off three times consecutively; 2. Disconnect the vehicle's battery for 15 seconds; 3. Wait until the engine fault light appears on the dashboard, then wait a few minutes before attempting to start the engine. If you are unable to resolve the anti-theft lock issue on your own, the only option is to seek assistance from a 4S shop. The vehicle can be towed to the 4S shop for a detailed inspection to determine the specific cause of the anti-theft lock. The issue can then be resolved based on the relevant fault codes, which is the most reliable method. Additional Information: The anti-theft system lock is a type of electronic anti-theft system for vehicles, also known as a chip-based anti-theft system. The basic principle of this system is to lock the vehicle's engine, as well as its electrical and fuel systems. Without using a key with the correct chip, the vehicle cannot be started, making it a highly secure method. Most vehicles today use this type of anti-theft system. The vehicle's chip key functions like a fixed identity recognition code, providing strong security. Once the code becomes disordered, the engine cannot start, and the vehicle cannot be driven.
The anti-theft system is locked, don't panic. Last time my car was parked in front of the supermarket, I couldn't open the door either. Try the spare key immediately - it's best to keep one at home as it can be a lifesaver in emergencies. If the spare key doesn't work, the key battery might be dead. Try replacing it with a new CR2032 battery, as weak signals often come from aged batteries. Next, check your car battery voltage - low power can disable the anti-theft system, and failure to start the engine might indicate this. Resetting the system is simple: disconnect the negative terminal of the battery for 5-10 minutes, then reconnect to reboot the system. Always perform this operation in a safe place with the handbrake on - never do it in the middle of the road. As a preventive measure, get into the habit of changing the key battery every two years. If all else fails, don't force things to avoid damaging components - directly contact a 4S shop or professional mechanic who have decoding tools. Safety first - when locked out, avoid randomly hitting the car doors as it only worsens the situation.
