Why doesn't the BMW make a sound when locking?
2 Answers
BMW vehicles do not emit a confirmation sound when locking (only the locking mechanism sound is heard), and this feature cannot be configured. Owners can drive their cars to a 4S store or professional auto repair shop, where technicians can enable this function through computer programming. Taking the 2021 BMW X1 sDrive20Li Fashion model as an example: it is a compact SUV with dimensions of 4565mm in length, 1821mm in width, and 1620mm in height, with a wheelbase of 2780mm. The 2021 BMW X1 sDrive20Li Fashion is equipped with a 1.5T turbocharged engine, delivering a maximum power of 103kW and a peak torque of 220Nm, paired with a 7-speed dual-clutch transmission.
I also encountered the annoyance of no sound when locking my BMW 5 Series before. It took me a year or two to realize it was a central control setting issue. In the iDrive menu, navigate to vehicle settings, find the door lock options, and the sound alert might be turned off; many owners like me didn't pay attention to the default settings, hence no sound. Additionally, if the horn or alarm module is aging or has moisture seepage, it can also cause a silent malfunction, which I only checked during regular maintenance. Once, my car was parked outdoors and got soaked by rain, causing a short circuit in the module and the horn not to sound. Timely repairs prevented greater safety risks. Also, when the key battery is nearly depleted, the weak signal affects the lock confirmation sound, so it's advisable to try replacing the battery. Overall, these minor issues are easy to solve—first, check the settings yourself, and if that doesn't work, seek professional repairs to ensure the car's safety.
