How to Turn Off the Horn Sound When Locking the Car?

[DelJourney]

To turn off the horn sound when locking the car, follow these steps: 1. Pull the door handle to open the driver's door; 2. Press the one-touch start button; 3. When the dashboard lights up and the vehicle's power is on, simultaneously hold down the lock and unlock buttons for 3 seconds. Notes on using the horn: 1. Avoid getting the horn wet when washing the car; if it gets wet, dry it as soon as possible; 2. Do not press the horn for extended periods, as this may cause premature wear of the horn contacts. The working principle of the horn is: When the horn button on the steering wheel or other positions is pressed, current from the battery flows through the circuit to the electromagnetic coil of the horn relay. The electromagnetic coil attracts the moving contact switch of the relay to close, allowing current to flow to the horn. The current causes the electromagnet inside the horn to work, vibrating the diaphragm to produce sound.

That day I was troubled by the overly loud car lock beep, and my neighbors came to complain. I was fiddling with the car key when I suddenly discovered that holding down the lock and unlock buttons for ten seconds made the headlights flash twice. After that, the sound was gone! If this trick doesn’t work, you can sit in the car without starting it, navigate to the vehicle settings in the infotainment screen, and find the option for lock confirmation sound to turn it off. The settings location varies by car model, so if you can’t find it, check the owner’s manual or ask the 4S technician to adjust it during maintenance. Now my car locks quietly, and I no longer worry about waking up the whole building.
