What causes the Haval H6 to fail to detect the key and not start?
4 Answers
The reasons why the Haval H6 cannot detect the key may be due to a dead key battery or incorrect placement of the remote key. Here are some additional details: 1. Key not detected: If the keyless entry system displays "Key not detected," you can place the chip key against the keyless button and then start the ignition, which usually works. When the vehicle control panel displays "Key not detected," it is likely that the key battery is dead, and you need to promptly replace it with a new large button battery to resume normal use. 2. Inspection and replacement: When using the keyless start feature, sometimes the car key may not work even when placed very close, and if the battery is new, it indicates an issue with the key chip, requiring inspection and replacement. 3. Precautions: For vehicles with keyless start, it is especially important to protect the key. Avoid frequently dropping the key, exposing it to moisture, or demagnetization to prevent damage.
I've been driving a Haval H6 for a few years and have encountered the annoying issue of the key not being detected and failing to start the car. The most common cause is a depleted key battery—when it runs out of power, it can't send signals, and the car can't detect it. The battery is a CR2032 button-type cell, which you can buy at supermarkets or auto parts stores and replace by opening the key casing yourself. Another possibility is a weak car battery; after prolonged parking, the voltage drops too low, preventing even the keyless system from starting. In this case, check if the car lights turn on or try jump-starting. Signal interference is also frustrating—phones, power banks, or metal objects near the key can block the signal. The solution is simple: first, place the key close to the start button or the designated induction area inside the car. If that doesn't work, try using the spare key. Don’t panic—take it step by step. Regular checks can help prevent these issues.
The intelligent key system of the Haval H6 is quite convenient, but occasionally has issues. When the key isn't detected and the car won't start, there are usually three reasons: first, the key's battery is low—weak signal when power is insufficient; second, the car battery is aging or dead—low voltage prevents system activation; third, external interference, such as the key being surrounded by metal objects or near other electronic devices. I recommend first trying a new battery, model CR2032, which costs just a few bucks. Then check the car battery’s condition—if the headlights are bright before starting, it’s fine. If the signal is blocked, move the interfering objects or restart the car. Don’t forget the spare key—it can be a lifesaver in emergencies. Develop good habits: don’t keep the key with your phone.
Key not detected and unable to start the engine, this has also happened with my Haval H6. The main reasons are either the key battery is depleted or there's poor contact. Open up the key to check the battery model, usually it's a CR2032, replacing it will likely solve the problem. It could also be that the car battery is dead from being parked too long, causing a voltage drop and sensor failure. Try using the mechanical spare key to open the door and start the car. Other minor reasons include strong interference sources, just keep away from mobile phones and it should be fine. Don't panic, you can usually fix it yourself.
