My Haval H6 had a false alarm issue with its anti-theft system before. At that time, I used the mechanical key to open the door, got into the car, closed all windows and doors tightly, then pressed the original key against the start button and held it for three minutes to deactivate it. Later, I asked a mechanic and learned that some cases are triggered by unstable battery voltage, and you need to disconnect the negative terminal for two minutes to reset the computer. However, this method will clear the radio memory, so remember to turn off all electrical devices before performing the operation. Now, the Haval APP can also remotely unlock the anti-theft system, but you need to bind the vehicle in advance. If you really can’t deactivate it, don’t force it—just contact the 4S店, and they can fix it in minutes using a diagnostic tool.
Disabling the Haval H6 anti-theft system has its tricks. Here's a simple step-by-step guide: First, check the remote key's battery—if it's dead, try replacing the coin cell. Then, sit in the driver's seat, close the door, press and hold the brake pedal while pressing the start button for 10 seconds. Release only after the anti-theft light on the dashboard goes off. Some owners report false triggers on rainy days—just use a hairdryer to dry the door lock sensor. Also, an improperly closed trunk can activate the system, so reclose it firmly and listen for the latch sound. Lastly, be cautious with aftermarket circuit modifications, as non-OEM devices can interfere and cause the anti-theft system to malfunction.
