What are the reasons why the BYD G6 cannot detect the key?

The reasons why the BYD G6 cannot detect the key are: 1. The key battery is dead. Press any button on the key to test if the indicator light turns on. If it doesn't, it means the battery is dead; 2. Poor contact of the battery in the key. You can rotate the battery or remove and reinstall it, then test again; 3. The car's location has battery interference or signal interference sources, which can also prevent the car from detecting the key. The BYD G6 has a body length, width, and height of 4860mm, 1825mm, and 1463mm respectively, with a wheelbase of 2745mm.

I just bought a BYD G6 not long ago, and this issue of not detecting the key is quite annoying. Most of the time, it's because the battery in the remote key is depleted—those small round coin batteries, model CR2032, need to be replaced every year or two. Buying a new one from a supermarket or online store and installing it usually solves the problem. If the key itself has been dropped or gotten wet, the internal circuitry might short-circuit and malfunction, so it's worth checking if the buttons respond normally. There could also be issues on the car's side, such as poor contact in the key reception module or a blown fuse, which can affect signal reception. Interference is another potential problem—parking under large trees or near high-voltage lines can easily block the signal. I've tried it myself: first, replace the battery and move away from potential interference sources; if that doesn't work, then a trip to the 4S store to re-pair the key is necessary to avoid disrupting daily commutes. These minor issues are simple to handle, so don't let them ruin your good mood.

From my experience, there are several common causes for BYD G6 key detection failures. First consider if the key battery is dead - the CR2032 coin cell naturally depletes over time, and replacing it usually solves the issue. If the key has been dropped or gotten wet, internal chip damage may require repair. On the vehicle side, oxidized receiver contacts or blown fuses can block signal transmission, while interference environments like near parking lot metal railings may disrupt induction signals. Additionally, low car battery voltage may cause system instability and temporary lockups - waiting a moment before retrying often helps. Recommended troubleshooting sequence: 1) Replace battery and check key integrity away from vehicle; 2) Inspect fuse box locations; 3) Consider system reset or professional diagnostics for safe resolution.

I often encounter key detection failure issues when driving my BYD G6, which is extremely frustrating. The most common cause is a dead key battery—the small round CR2032 battery runs out of power. Spending a few bucks to buy a new one and replacing it usually solves the problem. Another reason could be damage from dropping the key or internal components burning out due to moisture. Sometimes, the car just acts up when parked in areas with strong interference, making it unable to receive signals—wait a few minutes and try starting it again. If all else fails, take it to the shop for repairs instead of wasting time trying random fixes.
