How to Start a Haval Car When the Key Fob Battery Dies?

[StSadie]

Pull out the mechanical key from inside the smart key fob and use it to unlock the car door. Place the side of the key with the LOGO imprint against the start button to ignite the vehicle. All cars have a keyhole; locate it, remove the protective cover hiding the mechanical key slot, and then unlock the door.

Many people have encountered the situation where their Haval key fob runs out of battery. Let me teach you the emergency start method. First, look at the back of the remote key fob—press the small button to pull out the mechanical key blade, and use it to unlock the driver's door. Then, sit in the car calmly, place the dead key fob against the push-to-start button, press the brake pedal, and then press the start button—the sensing system will recognize the key. After starting, immediately go to an auto repair shop to replace the battery, which is usually a CR2032 coin cell. It's a good idea to keep a couple of spare batteries in the glove box. Remember to keep the car key away from induction cookers or mobile phones when not in use for long periods to avoid premature battery drain. Changing the battery yourself is simple—just use a coin to pry open the key fob's back cover, but be careful not to reverse the positive and negative terminals.

My Haval also had a key battery issue before, but the manufacturer had already designed a backup solution. Take out the remote key and find the hidden mechanical key. There's a small cover on the driver's door handle—pry it open to insert the key and unlock the door. Once inside, here's the key point: press the key directly against the start button, keeping it close like swiping a card, while stepping on the brake and pressing the button. If it doesn’t start, try adjusting the angle or placing the key in the induction area at the bottom of the cup holder. After successfully starting, it’s best to replace the battery the same day—just buy a CR2032 battery from a supermarket or hardware store. As a reminder, shortened remote range or dim buttons are early warning signs of a low battery.

Emergency start with a dead key fob involves three steps. First, use the metal key blade to unlock the door, being careful not to force the plastic cover. Once seated in the driver's seat, press the remote against the start button for 5 seconds to allow the system to re-recognize the signal source. Then start the engine normally by pressing the brake. This method works for most Haval models, including the H6 and H9. Replace the key fob battery as soon as possible after starting, and be cautious not to damage the circuit board during DIY replacement. It's recommended to check the key fob's battery level annually, as sudden power loss may trigger the anti-theft system to lock the vehicle.

Haval's keyless start system has a low-power protection mechanism. When the remote key is completely out of power, use the metal key at the end to unlock the door. After entering the vehicle, press the entire key against the start button and maintain contact as if charging. The key point is to firmly press the brake pedal before ignition. I've seen cases at repair shops where failure to press the brake pedal sufficiently caused startup failure. Remember the battery model is CR2032, which can be bought at supermarkets for about ten yuan. When replacing it yourself, use your fingernail to pry open the key casing, which is less likely to cause scratches than using a screwdriver.

I was also confused when I first encountered a dead key fob battery, but later found Haval's emergency start feature to be quite user-friendly. The mechanical key is hidden inside the remote—after unlocking the door, don't rush to call for a tow truck. The key is to place the fob body close to the induction area below the steering wheel (location varies slightly by model; for my Big Dog, it's on the side of the steering column). Keep the key stationary for over three seconds before starting. To prevent complete battery drain, it's recommended to proactively replace the battery every two years, especially since cold winter temperatures drain it faster. When replacing the battery yourself, be mindful of static electricity—using a plastic pry tool is ideal. Avoid storing car keys in the same pocket as magnets, as this accelerates battery depletion.
