How to solve the problem that BYD G3 cannot detect the key?

[DeRylee]

Solutions for BYD G3 not detecting the key are as follows: 1. You can directly place the key next to the one-button start. 2. The key may have no power or battery issues, or it could be due to leakage causing the power to drain prematurely. 3. The transmitter or receiver may be faulty, so it is recommended to replace the battery. Below are some reasons why a car may not detect the key: 1. There may be signal interference in the surrounding area. If there is interference, try to find a location where the signal can be received. Some dash cams, if not properly shielded, can also cause interference, preventing the key from being detected. 2. The anti-theft system may not be deactivated, the signal cannot be found, or the key may have been dropped or bumped, causing the chip inside the key to shift. 3. Poor contact in the car key battery. You can remove the key casing, rotate the button battery, or take it out and reinstall it after a while. 4. The smart box sensor may be damaged. Although this is rare, it cannot be ruled out.
