What is the reason why the Haval H6 remote key cannot lock the doors?
3 Answers
The reasons why the Haval H6 remote key cannot lock the doors are: 1. The car remote lock is malfunctioning or there is an issue with the car body itself; 2. Due to colder weather, some grease in the remote becomes sticky, leading to poor contact; 3. There is strong magnetic signal interference around where the car is parked. Taking the 2021 Haval H6 as an example, its body dimensions are: length 4653mm, width 1886mm, height 1730mm, with a wheelbase of 2738mm. The 2021 Haval H6 is equipped with a 2.0T turbocharged engine, with a maximum power of 155kW and a maximum torque of 325Nm, paired with a 7-speed dual-clutch transmission.
Having driven the Haval H6 for several years, I've frequently encountered issues with the remote key failing to lock the doors, and I must say there are quite a few reasons for this. The most common one is a dead key battery, which prevents the remote signal from being transmitted—this can easily be fixed by replacing it with a new battery. Another major issue is when the doors aren't properly closed, such as leaving a gap in the trunk or one of the doors, causing the central locking system to deem it unsafe and refuse to lock. The remote key itself might also malfunction, such as after being dropped or exposed to water, leading to unresponsive buttons. On the vehicle side, a blown fuse in the door lock or a faulty central control module could interfere with signal reception. Additionally, environmental factors shouldn’t be overlooked—nearby large electronic devices or base stations can generate interference, causing the key to fail. A temporary solution is to manually lock the doors using the mechanical key, ensuring safety before promptly visiting a 4S shop for inspection. For preventive maintenance, it’s recommended to check the key battery and door sensors every six months to save hassle.
As an owner of the Haval H6, I encountered an issue last month where the key couldn't lock the doors, and the cause turned out to be quite straightforward. The most likely reason is that the key battery is depleted—try replacing it with a new coin cell battery. Another factor is the door status; make sure both the driver's door and rear doors are securely closed. If any door isn't properly shut, the central locking system won't allow the car to lock. A faulty remote button is also common, especially after prolonged use when the buttons become loose. On the car's side, a blown fuse or a stuck door lock actuator can cause this issue. External interference, such as being near high-voltage power lines in a parking lot, can also block the signal. I recommend starting with simple troubleshooting. If that doesn’t work, use the physical key for emergency locking and then seek professional repair to avoid travel delays. Regularly inspecting these components during maintenance can significantly prevent such malfunctions.
