Why can't the remote key of Haval H6 lock the car?
4 Answers
The reasons why the remote key of Haval H6 cannot lock the car are: 1. Fault in the central locking module; 2. Damage to the key's transmitter; 3. Low battery in the key. The Haval H6 is a compact SUV with body dimensions of: length 4653mm, width 1886mm, height 1730mm, and a wheelbase of 2738mm. The Haval H6 is equipped with a 2.0L turbocharged engine, delivering a maximum horsepower of 211PS and a maximum power of 155kW. It adopts a front-engine, front-wheel-drive layout, with MacPherson independent suspension at the front and double-wishbone independent suspension at the rear.
When encountering a situation where the remote key cannot lock the car, I usually start by checking the simplest issue - the battery. Recently, when dealing with a malfunctioning Haval H6 key, I found that the key battery was simply depleted. I spent ten yuan to buy a CR2032 battery and replaced it myself, which solved the problem. However, sometimes it could also be due to a door not being closed properly, the trunk not being locked securely, or an issue with the door sensor. You can try manually closing the door a few times. If everything seems normal but the key still doesn't respond, it's likely due to strong signal interference nearby, such as from high-voltage power lines or large electronic devices. Parking in a different location can help verify this. The most troublesome scenario is when the key chip itself is damaged or there's a fault with the body control module. In such cases, it's necessary to visit a 4S shop for professional equipment testing.
Last time my neighbor's Haval H6 also encountered the issue where the key couldn't lock the car. It turned out the spare key was left inside the vehicle, and the system mistakenly thought the owner was still in the car, thus refusing to lock. This situation is quite common—remember to check if there's a spare key or electronic devices like phones left inside that might interfere with the signal. If none of these are the issue, you can try the mechanical lock function of the key. Usually, there's a hidden mechanical key slot at the end of the key for temporary locking. However, be aware that long-term use of the mechanical lock might wear out the keyhole, so it's best to check the central control system for fault codes as soon as possible. Also, don't overlook whether the key casing is cracked from drops, as damage to the internal circuit board can also cause abnormal signal transmission.
Seeing this question reminds me of my own experience last year: I kept pressing the remote key but the car lights didn't respond. First, I checked the voltage of the key battery, and it was fine. Then I found that the sensor on the driver's side door handle had poor contact, and slightly adjusting the rubber seal solved the problem. If the sensor is working properly, you can try the spare key. If the spare key works, it means the issue is with the main key. If all else fails, there's an emergency method: hold down the unlock button on the key without releasing it, and wait for the car lights to flash twice to synchronize the signal. This method is particularly useful when the remote suddenly stops working, but if the problem keeps recurring, you'll need to check the wiring or module.
