Why does the Haval H6 anti-theft lock light stay on and the car won't start?
2 Answers
Haval H6 anti-theft indicator light stays on and the car won't start because the vehicle's anti-theft system fails to recognize the smart key. In this case, simply place the car key on the one-touch start button or in the storage slot to resolve the issue. Detailed explanations are as follows: 1. Ignition system: It might be due to faulty spark plugs or ignition module, preventing the spark plugs from igniting, thus the air-fuel mixture cannot be ignited and the vehicle fails to start. 2. Fuel injection system: Possible issues include malfunctioning fuel injectors, insufficient fuel pressure from the fuel pump, or faulty fuel injector wiring, leading to failure in fuel injection and preventing the vehicle from starting. 3. Starting system: The problem could be a damaged battery in the starting system lacking sufficient power to drive the starter motor, or a faulty starter motor itself, resulting in the vehicle's failure to start.
The theft-proof lock light of the Haval H6 is on and the car won't start. I've seen this situation quite a few times in my years of driving. The reason is usually that the anti-theft system has locked the engine from starting, mainly because the key signal isn't being recognized by the car. The most common issue is a dead key battery—the Haval key uses a CR2032 coin cell battery, which typically lasts about two years. I suggest you try the spare key first; if it starts the car, replace the battery immediately. If that doesn't work, it could be a fault in the anti-theft module or ECU, such as the system misjudging interference signals—things like other electronic devices or strong magnetic fields in the garage can easily trigger this. Also, check if the key has been dropped or has poor contact, or if the car battery is low on power, as these can also affect it. Get it diagnosed at a Haval 4S shop as soon as possible, and avoid forcing a start to prevent engine damage. Keep the key dry and away from your phone in daily use, and regular checks can help prevent issues.
