How to Set Up the Car Lock Horn?
1 Answers
Method to set up the car lock horn: In the car's onboard computer settings, select the lock option and click 'Lock ON' to enable the car lock horn function. Once enabled, you can hear the horn sound when locking the car, ensuring that the doors are securely locked. In some Volkswagen models, the horn does not sound when locking the car by default in the factory settings, making it difficult for many car owners to determine if the doors are locked or open. So, how can you set up the horn sound to avoid this concern? To activate the car lock horn sound using the remote key, simultaneously press the unlock and lock buttons for 3 seconds until the light flashes. This will enable the horn sound. To restore the horn sound, press the lock and unlock buttons simultaneously for 3 seconds until the light flashes again. To disable the car lock horn sound, go to Settings - Sound - Screen Lock Sound - Play sound when locking and unlocking the screen. If you don't want the sound to play when locking the screen, simply uncheck the box. The horn sound is produced by electromagnetic vibration, where the electromagnetic coil attracts the relay's moving contact switch to close, allowing current to flow to the horn. This current activates the electromagnet inside the horn, causing the diaphragm to vibrate and produce sound. Air horns are mainly used in heavy-duty trucks with air brake systems, while electric horns are widely used in small and medium-sized vehicles due to their simple structure, compact size, lightweight, pleasant sound, and easy maintenance. To ensure normal horn sound, the horn should not be rigidly mounted but fixed on a cushioned bracket, with a leaf spring or rubber pad between the horn and the fixed bracket. To lower the horn sound, completely turn off the car, retract all displays, and then restart the engine.
