Why can't the Haval H6 detect the key?
3 Answers
Haval H6 cannot detect the key for the following reasons: 1. The keyless entry system displays "Key not detected." Place the chip key close to the keyless button and then start the ignition. 2. The key battery is dead; replace it with a new large coin battery promptly. 3. The car key is too far from the ignition switch, such as being placed in the trunk or back seat. It is better to place it in the storage slot in front of the armrest box. 4. When using the keyless one-button start, the car key does not work even when placed close. If the battery has been recently replaced, it indicates an issue with the car key chip, which requires repair or replacement. 5. For vehicles with keyless one-button start, pay special attention to protecting the key—avoid dropping it, exposing it to moisture, or demagnetizing it to prevent damage. 6. While driving, ensure the key is kept relatively close to the keyless one-button start button.
My sister's Haval H6 had the same issue the other day! Turned out the key fob battery was dead, and replacing the button cell solved it. Actually, having power banks or phones randomly placed in the car can also cause signal interference. Once, my brother stuck the key to a magnetic phone holder, and the car couldn't recognize the key at all. There's also this weird situation where strong electronic interference near certain banks or signal towers can cause problems—just moving to a different parking spot fixes it. If all else fails, try using the mechanical key to open the door, and driving for a bit might let the signal module reset itself. But if the anti-theft red light on the dashboard stays on, you might need to visit the 4S店 for a system reset.
I often encounter this issue when repairing cars. In 80% of cases, the Haval H6 not detecting the key is due to insufficient battery power in the key itself, especially for keys older than two years. Additionally, check if the key casing is cracked, which could cause a loose solder joint on the circuit board. Don't overlook interference from small electronic devices in the car either; an overloaded car charger can emit noise that disrupts the key signal. Another hidden fault point is a loose connector on the sensing module under the steering wheel—simply plugging it back in firmly yourself should fix it. If all these possibilities are ruled out, the anti-theft module might be faulty, which requires professional equipment to diagnose the error code. It's best to develop the habit of keeping spare keys in separate locations.
