How to Set the Car Horn to Sound When Locking the Vehicle?
2 Answers
In the car's computer settings, select the lock option, then click 'Lock ON' to enable the horn sound feature when locking the vehicle. Locking Methods: Use the lock button on the key to lock the doors or lock the doors via the sensing method. The sensing method refers to the keyless entry feature used by most vehicles today. When the driver approaches the car, the vehicle detects the key signal and automatically unlocks the doors. When the driver moves away from the vehicle, the car detects the key signal getting weaker and automatically locks the doors, activating the anti-theft mode. Principle of the Locking Horn Sound: The sound is primarily produced by electromagnetic vibration. The electromagnetic coil attracts the moving contact switch of the relay 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. Therefore, the horn sounds when the vehicle is locked.
I think setting the car horn to sound when locking is a very practical feature, as it instantly confirms the car is locked, especially at night or in noisy environments. My personal approach is: first test the remote by pressing the lock button two or three times or holding it down for a few seconds. If there's no response, get into the car, turn on the power (without starting the engine), use the steering wheel buttons to navigate to the vehicle settings menu, select comfort functions or alarm options, and enable the lock confirmation sound. Most modern cars support this, but remember methods vary slightly by brand; German cars like Volkswagen often require menu settings, while Japanese cars might use remote combinations. The safety benefits are significant, helping prevent theft due to forgetting to lock. If unsuccessful, check the manual or visit a 4S shop for programming. Also, it's advisable to develop a habit of checking the lock manually, not just relying on alerts.
