Why doesn't the Haval M6 beep when locking the car?

Haval M6 does not beep when locking the car because it is not set. The setting method is: close all vehicle doors completely, then simultaneously press the lock and unlock buttons on the vehicle remote control for seven seconds to set the locking sound. The Haval M6 is a compact SUV under Great Wall Motors, featuring a 5-door, 5-seat structure with MacPherson independent front suspension and double-wishbone independent rear suspension. In terms of power, the Haval M6 is equipped with a 1.5L inline four-cylinder turbocharged engine with an aluminum alloy structure, delivering a maximum power of 110kW and maximum torque of 210Nm, paired with either a 6-speed manual or 7-speed dual-clutch transmission.

When I first drove the Haval M6, I was also puzzled why there was no sound when locking the car. Later, I figured it out. The locking sound of this car can be set by yourself, and you need to operate it on the central control screen. Go to the vehicle settings to find the security option, and turn on the locking sound. If there is still no sound after setting, it is probably due to poor line contact or a blown fuse, especially in damp places after washing the car. In addition, I noticed that some low-end Haval models have the prompt sound turned off by default at the factory, and only high-end models have the sound. Last time I went for maintenance, I asked the mechanic to check it, and he just wiped the connector under the steering wheel and it was restored. Usually, when I park the car in the community, the lack of a prompt sound does not disturb the neighbors in the middle of the night.

If your car doesn't make a sound when locking, don't panic. First check if the key fob battery is running low. If the car lights flash when you press the lock button, there's no major issue - it means the signal reception is normal. Focus on checking the settings menu: go to the central control, find Vehicle Settings > Lights and Sounds, and see if the sound option is turned off. If that's not the problem, the horn control module under the steering wheel might have poor contact, requiring removal of the steering wheel trim panel for inspection. I've also encountered cases where the passenger footwell mat pressed on wiring causing a short circuit. If you can't figure it out, note down the VIN and call Haval customer service with your specific model and year - they'll provide official solutions. Parts for this car aren't expensive; replacing the horn wiring harness yourself costs just over 100 yuan.

The silent locking issue with Haval M6 is mostly due to system settings. Page 83 of the owner's manual states you can adjust the alert type: horn sound or light flash. You need to operate with the engine on: press the steering wheel menu button to enter settings, find the door lock settings option, and check the sound alert checkbox. Remember to turn off the engine and test the locking after operation. If it still doesn't work, consider interference between aftermarket anti-theft devices and the factory system - for example, my neighbor's third-party GPS installation disrupted the alert sound. Another rare possibility: the unlock microswitch on the driver's door is stuck, making the vehicle think the door isn't properly closed and disabling the alert. Those with DIY skills can remove the door panel to clean out dust.

In the first few months after picking up my Haval M6, the locking sound was quite loud, but then it suddenly went silent. My troubleshooting experience was quite typical: first, I tried locking the car with the spare key to rule out a fault with the main key. Next, I checked the settings, and everything seemed fine. Finally, I found the cause by looking under the front bumper—the horn cover was clogged with mud, and rainwater had caused a short circuit. When I opened it up to clean it, I noticed the horn was mounted next to the crash beam, making it particularly prone to getting splashed with dirt. Now, I make sure to rinse the horn area regularly during car washes. This Haval design also has its benefits: the alert sound is quieter in decibels compared to Japanese cars, so locking the car at night doesn’t disturb the neighbors. If you frequently drive on rough roads, it’s best to have a mechanic add a waterproof cover to the horn.

As a frequent construction site visitor, my Haval M6 failed to beep when locking twice. The first time, it was due to water ingress in the central locking actuator module—the repair shop replaced the waterproof seal for 150 yuan. The second fix was simpler: a car group member suggested opening the fuse box under the steering wheel, locating the F15 15A fuse marked for the horn, removing it, cleaning the metal contacts with an eraser, and reinserting it. Now, in hot weather, I actually prefer the silent lock to avoid midday noise. However, when picking up my kid, I make it a habit to tug the rear door handle to confirm locking before leaving. A word of advice: avoid random electrical modifications—Haval's wiring system is particularly sensitive.
