How to Set the Horn Sound When Locking a BMW?
2 Answers
BMW does not support setting a horn sound when locking the car. The locking process only produces a locking sound without any horn. If you insist on enabling this feature, the only solution is to reprogram the ECU (Engine Control Unit). However, this method requires professional assistance for operation. BMW is a German automotive brand under the BMW Group, offering four model categories: i, X, Z, and pure numeric series (e.g., 1, 2, 3), along with the performance-oriented M series based on these models. The BMW 6 Series GT is a mid-to-large-sized car under the BMW lineup. It features standard LED lighting across all trims, with sleek body lines that complement its fastback design—blending elegance with sportiness. The front bumper design further enhances its aggressive appearance.
Every time I drive my BMW, I set the horn confirmation for locking the car, a habit developed from years of driving experience. The method is to first start the engine after getting in the car, not rushing to drive off, then use the iDrive knob to select the 'Settings' or 'Vehicle' section in the main menu. Scroll down to see if there's a 'Door Locks' or 'Comfort Features' option, click into it to find the 'Horn Confirmation' switch, and turn it on. Once enabled, there will be a beep every time the car is locked, especially useful at night or in busy areas to confirm secure locking and avoid issues from forgetting to lock the car. The interface is clear when operating on my X3, but there might be slight differences in the new 7 Series, so it's recommended to set it while the engine is running rather than in the off state. This setup is not only convenient but also enhances the sense of security. Once it becomes a habit, driving becomes more reassuring. Spending a little extra time on this is definitely worth it.
