If activation fails, try moving the vehicle somewhere with better network coverage and repeat activation in the app. For everyday use, turn on your phone’s Bluetooth, approach the car and open the BYD App. The manual also describes a manual Bluetooth connection in the app.

If an already activated key won’t connect, try switching Bluetooth off and back on or restarting the app. Availability, supported commands and phone compatibility depend on the vehicle and market. Test your setup with the physical key handy before relying on the phone alone.
