What is the reason why the Haval H6 remote key cannot lock the doors?
2 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.
