How to Set the BYD F3 Horn to Sound When Locking the Car?
2 Answers
To activate the horn sound when locking the car with the remote key, simultaneously press the unlock and lock buttons for 3 seconds until the light flashes. Settings - Sound - Screen Lock Sound - Play sound when locking and unlocking the screen. To ensure the horn sounds properly, it should not be rigidly mounted. A leaf spring or rubber pad must be installed between the horn and the fixed bracket.
Setting the horn beep when locking the BYD F3 is actually quite simple. I often use this feature to confirm successful locking, especially in noisy places like shopping malls. The specific steps are: After getting in the car and closing all doors (without pressing the brake), press the start button once to illuminate the dashboard without starting the engine (this is the ACC state). Then quickly press the lock button on the remote key about 4 times in succession. If the horn beeps once, it means the setting is successful. If there's no response, check whether all doors are properly closed or if the remote battery is running low - try replacing it with a new one. Don't worry if it doesn't work occasionally due to operational errors, just press a few more times. This setting helps avoid accidental triggers or safety issues, making it a very practical feature. I usually check the status when washing the car or parking.
