Why can't the Great Wall H6 detect the key?
3 Answers
The Great Wall H6 may not detect the key due to a depleted key battery or incorrect placement of the remote key. Below is an introduction to the performance of the Great Wall Haval H6: Safety Performance: The Haval H6 has good safety performance, with a total deviation score of only 12% in the three C-NCAP crash tests, ranking third among 23 SUV models. Power: Equipped with a 1.5-liter turbocharged engine, it delivers a maximum horsepower of 150 PS, torque of 210 Nm, and a maximum power of 110 kW at 5600 rpm. Exterior: The body length is slightly smaller than the H5, and the exterior design is more mature.
Last time I drove my cousin's Haval H6, I encountered the same issue. The key was clearly in my pocket but the car just couldn't detect it. After struggling for a while, I found out the key battery was almost dead, and replacing the button battery solved it. However, there are other reasons for this problem, such as the key being placed near a phone causing signal interference, or dust in the car's induction module leading to poor contact. Once, in an underground mall parking lot, I couldn't get it to sense no matter what, only to realize later that the parking spot was right next to a large iron pillar interfering with the signal. Another car enthusiast mentioned his key stopped working after being soaked in water, and the mechanic said the circuit board was short-circuited. For such issues, it's best to try changing locations first; if that doesn't work, use the mechanical key for emergency access.
I've encountered two instances of key fob failure in three years of driving my Great Wall H6. The first time was during winter with temperatures below -10°C. The mechanic said the battery's performance deteriorates in cold weather, and replacing it with a cold-resistant battery solved the issue. The second occurrence was more peculiar – it turned out the dashcam power cable was interfering with the key fob's induction circuit. Actually, vehicle key detection involves multiple steps: the key must transmit signals properly, the door antenna needs to receive them, and then the BSI control module must decode them. I recommend keeping spare key batteries at home and avoiding storing keys in the same pocket as your phone. If it happens, try using the mechanical key to open the door, then press the ignition button with the key touching it.
