What is the reason why the Haval H6 Coupe cannot detect the key?
2 Answers
The reason why the Haval H6 Coupe cannot detect the key is due to reasons such as the key battery being dead. Below are the relevant details: Key battery dead: If the keyless entry system displays "Key not detected," you can place the chip key close to the keyless button and then start the ignition. Note that when the vehicle control panel displays "Key not detected," it is likely that the key battery is dead. You need to promptly replace it with a new large button battery, after which it can be used normally. Key placed in the wrong position: Please check if the smart key is placed on the dashboard, floor, combination meter, storage compartment, or luggage compartment. The above situations may prevent switching the ignition switch mode. If necessary, you can try replacing the key battery.
I've encountered the issue of the Haval H6 Coupe not detecting the key several times since owning the car for nearly a year, and there are quite a few possible causes. The most likely culprit is a dead key battery—the CR2032 button cell used by Haval tends to drain quickly, especially in cold weather when it doesn't last long. Once, I parked in an underground mall garage and suddenly got the 'key not detected' alert, which was stressful, but replacing the battery fixed it immediately. Another common issue is signal interference; nearby strong electromagnetic sources like subway stations or wireless chargers can weaken the key signal. I’ve also experienced a faulty vehicle receiver—Haval’s receiver near the dashboard can accumulate dust or develop wiring issues, affecting recognition. Whenever this happens, I first try the spare key or hold the key close to the start button to wake the system. As a habit, I recommend avoiding exposing the key to moisture, replacing the battery regularly, and maintaining the car’s electronics to prevent being stranded. A quick tip: never ignore dashboard warnings—addressing them early saves hassle.
