How to Set the Car Lock Horn?
2 Answers
The car lock horn sound depends on the vehicle model. Some models have a lock horn feature, while others do not emit a sound when locked. Below are the setup methods for models with a lock horn: 1. If the car's computer has a lock horn option, you can enable or disable it through this setting. 2. If the option is not displayed on the car's computer, it can be activated via the bus system. In this case, you will need to visit a 4S shop or a repair shop for setup. 3. Some models allow the owner to manually configure the lock horn. 4. For certain models, you can set the car lock horn using the car key. Press both the unlock and lock buttons simultaneously for 3 seconds until the lights flash once. In this mode, the car will only flash its lights without sounding the horn. To restore the lock horn, press the lock and unlock buttons together again for 3 seconds until the lights flash, indicating successful setup. Below is a detailed introduction to the car lock horn: 1. The lock horn primarily produces sound through electromagnetic vibration. 2. The electromagnetic coil attracts the relay's moving contact switch to close, allowing current to flow to the horn's wiring. This current activates the electromagnet inside the horn, causing the diaphragm to vibrate and produce sound, which is why a sound is emitted when locking the car. 3. Some large trucks use air horns, while electric horns are characterized by their simple structure and compact size.
I recently figured out how to set up the horn sound when locking the car. First, sit in the car without pressing the brake pedal, then press the start button twice to illuminate the dashboard. Next, locate the vehicle settings icon on the central control screen, tap into it, and select either the security settings or door lock options. There should be a toggle for the lock confirmation sound—simply turn it on. However, menu locations vary by brand; my Volkswagen has it under lighting settings, while my friend's Toyota requires navigating through the dashboard menu settings. After setting it up, remember to close the car door and test it with the key—a beep means success. This feature is especially handy for locating your car in parking lots, but if you live in a residential area, it's advisable to turn it off at night to avoid disturbing neighbors. If you can't find this option at all, your car's base model might not include this function, and you may need to visit a 4S dealership to activate it via system programming.
