What are the reasons for the failure of the BYD F0 one-button start?

[MaximusFitz]

BYD F0's one-button start failure may be due to the following reasons: 1. Radio wave interference: Frequently placing the car key near electronic devices such as mobile phones, computers, or TVs can cause interference with the low-intensity radio waves in the key. Alternatively, strong radio waves from nearby sources like TV towers, airports, or power plants can also lead to a "failure" of the one-button start. 2. Dead key fob battery: If the remote control distance shortens or the key becomes less responsive, it may indicate that the key fob battery is running low. In such cases, the one-button start function will not work properly, and the battery should be replaced as soon as possible. 3. Vehicle malfunction: In extreme cases such as fuel system issues, dead battery, or short circuits in electronic components, it is recommended to directly call the 4S store staff for assistance.
