BYD F0 one-button start failure is caused by poor battery contact, engine malfunction, or lack of fuel. Reasons for no response from the one-button start: Usually, it's due to a brake switch issue preventing the vehicle from starting, or poor battery contact. You can first turn the key halfway to let the car self-check and see the prompts from the onboard computer. Then, try the conventional ignition method. If it still doesn't start, it's either an engine malfunction or no fuel. If all else fails, go to the after-sales service to check the fault. No response from the one-button start: It may be due to the car key battery being dead or nearly dead, resulting in low signal transmission power, making it difficult for the in-car sensors to detect the signal, thus preventing the one-button start from working.
