What to Do When the Haval H6 Key Fails to Start the Engine?

Related reasons: The key won't turn, and the car doesn't respond. There are many possible causes for this situation, but they are always related to the fuel system or electrical system. First, check if the fuel level is insufficient. When the car lacks its power source—gasoline—it naturally won't start. If there's no fuel, this situation is easily resolved. If it's an electrical issue, common faults that prevent the car from starting or responding include blown fuses, open circuits in the high-voltage coil, open circuits in the low-voltage circuit, detached central ignition wire, ignition head leakage, or damaged spark plugs. Note: For automatic transmissions, the correct gear positions for starting are P (Park) or N (Neutral). If the owner accidentally leaves the gear in R (Reverse) or any other position, not only will the car fail to start, but it also poses a safety hazard.
I've been driving for many years. If your Haval H6 won't start, it's mostly likely due to a dead battery. You can check if the headlights turn on - if they're dim, it's a battery issue. Try jump-starting it with a friend's car. Also check if the key is properly inserted or worn out. Haval keys may have anti-theft chips, so try gently turning it. Battery aging is a common cause, especially in winter when batteries tend to lose charge. Check if the battery terminals are loose. If it still doesn't work, it might be a starter motor failure - no sound means there's a problem. Regular maintenance can prevent these issues. Don't save small money only to spend on major repairs later. I recommend testing your battery every six months.
My Haval H6 had the same issue last time. Don't panic if it won't start; first, park the car in a safe place to avoid blocking intersections. The key might be out of battery—Haval car keys use a CR2032 button cell, which you can replace yourself. Avoid repeatedly trying to start the car, as this can easily blow a fuse. The best solution is to contact your insurance company for roadside assistance or call the 4S dealership—they have professional tools to diagnose wiring issues, such as problems with the anti-theft system or starter relay. Always lock your car properly and avoid exposing the key to high temperatures to extend its lifespan. Safety first—don't mess around with it.
Currently, the Haval H6 uses a smart key electronic system. Most cases of failure to start are due to a depleted key battery, which can be resolved by replacing it. Try using the mobile app for remote start if this feature is available. Plug in an OBD scanner to read error codes and check for issues with the ignition coil or starter. A battery voltage below 11V may also cause problems—simply measure it with a multimeter. The electronic anti-theft system can sometimes lock by mistake; disconnecting the negative battery terminal for a few minutes can reset the system. Prevention is simple: replace the key battery once a year.
