How to solve the problem that BYD G6 cannot detect the key?

If the BYD G6 cannot detect the key, it may be due to a dead key battery or electromagnetic interference near the vehicle. Here are the solutions: 1. Press any button on the key to check if the indicator light turns on. If not, it means the key battery is dead and needs to be replaced. 2. If there is poor battery contact, use the mechanical key to open the key casing, rotate the battery or remove and reinstall it, then test again. 3. Use the spare key to test. If the spare key can unlock the car door, it means the currently used key is faulty and needs to be repaired at a service center. Note: If none of the above methods work, use the mechanical key to open the car door and drive the car to a 4S shop for inspection and repair by professional technicians.

I've been driving a BYD G6 for several years and have encountered the key detection issue a few times, usually minor problems that are easy to handle. First, check the key battery—it's a CR2032 model, and replacing it often solves the issue. Remember to avoid placing your phone near the key, as metal objects can interfere with the signal. There's a sensing area next to the start button; try pressing the key against it to start the car. The key sensor often gets dirty, so clean the door handle area with an alcohol wipe. If the key gets wet in rainy weather, dry it immediately and let it air out. If these steps don’t work, it's best to visit a professional shop—it might be an ECU module failure. During regular maintenance, have the key system checked, and get into the habit of replacing the battery to avoid hassle. Simple fixes can be done yourself, but don’t push through with complex issues.

As an automotive technology enthusiast, I've encountered key malfunction issues with the BYD G6. The most common cause is a dead battery - promptly replace it with a CR2032 battery. Signal interference also frequently occurs, such as from nearby high-voltage lines or mobile phone blockage; simply move away from these sources. Clean the sensor by gently wiping around the door lock with a small cloth. If the problem persists, disconnect the car battery's negative terminal for five minutes and then reconnect it to reset the system. Never forcibly break the key or lock, as this can lead to more dangerous situations like accidental locking. It's advisable to purchase simple testing tools to check signal strength; they're cost-effective and convenient. For long-term maintenance, inspect every six months and store the key in a dry place to extend its lifespan. Safety first - if issues recur, always seek professional diagnosis and repair from a 4S dealership.

I just started driving a BYD G6 not long ago, and it's quite embarrassing when the key isn't detected. A simple solution is to replace the battery—just buy a CR2032 from the supermarket. Try starting the car by placing the key closer to the start button. Sometimes, the signal is weak when the key is in your pocket, but it works fine when taken out and placed separately. If the sensing area is dirty, clean it by wiping the door handle with a damp cloth. A quick visit to the 4S store can resolve the issue in minutes—no need to disassemble it yourself and make things complicated. I've learned to carry a spare key for emergencies to avoid panic. During maintenance, remind the technician to check the key—fixing small issues early saves money and hassle.
