What to do if the BYD G6 cannot detect the key?
2 Answers
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 for when the key is not detected: 1. Dead key battery: Press any button on the key to check if the indicator light turns on. If not, it indicates the key battery is dead and needs replacement. Another possibility is poor battery contact in the key. You can use the mechanical key to open the key casing, rotate or reinstall the battery, and then test again. 2. Electromagnetic interference: If the vehicle is in an area with strong electromagnetic interference or signal interference sources, it may affect the key detection. Additionally, some dash cams installed in the vehicle without electromagnetic shielding can also cause interference. 3. If the above methods do not resolve the issue, use the mechanical key to open the door and drive the vehicle to a 4S store for professional inspection and repair by qualified technicians.
My BYD G6 had the same issue a while ago—suddenly couldn’t detect the key, which made driving a hassle. My first thought was to replace the key battery (CR2032, available at supermarkets for just a few bucks). A new battery usually fixes it. If that doesn’t work, check if the key got wet or the contacts are damaged. Sometimes restarting the car helps: turn off all doors, remove the key for a few minutes, then reinsert it. Environmental interference matters—avoid parking near signal towers or metal structures, as they can block signals. Preventive measures include regular battery changes and keeping the key clean. If the problem persists, it’s safer to get a professional check at the 4S store.
