Solutions for when the Haval H6 cannot detect the key: 1. If the keyless entry system displays "Key Not Detected," place the chip key against the keyless button and then start the ignition; 2. When the vehicle control panel displays "Key Not Detected," it means the key battery is dead, and you need to replace it with a new large coin cell battery to resume normal operation. The Haval H6 is a flagship model under the Haval brand, positioned as an urban intelligent SUV. In terms of body dimensions, it measures 4649mm in length, 1852mm in width, and 1710mm in height, with a wheelbase of 2680mm.
I had a similar issue with my Haval H6 before - the car suddenly couldn't recognize the key, which was quite annoying. The most common reason is a dead key battery, especially those small CR2032 button batteries that tend to drain after a year or two. You can try buying new ones at the supermarket to replace it. Also, avoid placing the key near phones or metal objects as it can cause signal interference. If changing the battery doesn't work, try using the spare key to start the car - this helps determine if the key itself is faulty. Additionally, sometimes the car's sensor area needs cleaning as dust buildup can cause malfunctions. Cold weather weakens battery performance, so pay extra attention during winter. Mention key system checks during regular maintenance to prevent minor issues. If this happens frequently, the signal receiver might be damaged - visit the 4S店 early to get it fixed and avoid last-minute troubles.
Encountering undetectable Haval H6 key is a common issue I've handled frequently, mostly due to dead key batteries. Before heading to the repair shop, try troubleshooting yourself: Use the spare key to check if the car starts - if it does, the main key is faulty; if not, inspect the relevant fuses in the fuse box. Then place the key near the start button under the steering wheel, as positioning sometimes solves the sensing issue. Avoid exposing the key to magnetic fields. Haval's key system design is straightforward - reprogramming often works; follow the steps in the manual or online tutorials. Don't overlook potential internal damage from water exposure or drops. During routine maintenance, remind technicians to test key voltage - a quick fix that takes minutes.
Haval H6 key not recognized? Usually caused by low battery power in the key. The wireless induction system relies on RFID technology, and insufficient voltage leads to weak signals or failure. Quickly replace with a new CR2032 battery - a DIY fix costing just a few yuan, with online videos teaching disassembly. If that doesn't work, it might be a fault in the car's signal reception module, such as installation position issues or aging wiring. Use the mechanical key for emergency door opening and starting - it can open but requires checking pairing settings if induction fails. Consider interference sources like nearby high-voltage lines or electronic devices, try moving them away. Occasional system misjudgments can be resolved by disconnecting the negative battery terminal for a few minutes to reboot. Preventive measures include keeping the key dry and regularly testing sensitivity - don't wait until complete failure to take action.
