How to Set the Car Lock Beep Sound?

To activate the car lock beep sound using the remote key, simultaneously press the unlock and lock buttons for 3 seconds until the light flashes. The electromagnetic coil attracts the moving contact switch of the relay to close, allowing current to flow to the horn. The current activates the electromagnet inside the horn, causing the diaphragm to vibrate and produce sound. Settings - Sound - Screen Lock Sound - Play sound when locking and unlocking the screen. To ensure proper sound, the horn must not be rigidly mounted. It should be fixed on a cushioned bracket, meaning a leaf spring or rubber pad should be installed between the horn and the mounting bracket.
I often tinker with cars, and setting the horn sound when locking the car is quite simple, mainly depending on whether your car model supports it. There are usually two methods of operation: one is to press and hold the lock button on the remote key for a few seconds, such as holding it for about 5 seconds, until you hear the horn beep once or see the indicator light flash, which means the setting is successful. This way, the horn will sound once every time you lock the car as a reminder. The other method is to enter the vehicle settings menu, find the "Comfort Functions" or "Security Settings" on the car screen, where there is a "Lock Confirmation Sound" option—just turn it on. I've set this up many times and find this small feature very practical, especially in crowded parking lots, as it immediately confirms the car is locked to prevent theft. However, if it doesn’t work, it might be due to a dead remote battery or the car itself not supporting this feature (like some older models). It’s recommended to check the manual or try different button combinations. Also, be mindful not to set the sound too loud late at night to avoid disturbing others. Most cars allow you to adjust the volume in the settings. You can do it yourself without needing to visit a 4S shop, saving some money.
