How to enable the horn sound when locking BMW X3?
2 Answers
BMW's locking system does not produce a horn sound by default, only the locking mechanism sound, and there is no setting available to change this. It requires ECU flashing to enable this feature. However, this method is relatively complicated and needs professional assistance to perform the operation.
Setting the audible reminder for locking the BMW X3 is quite interesting. I usually enjoy exploring various small features in the car. The method is to start the car, then open the central control screen, find the 'Vehicle Settings' or 'Door Lock' option, where there is usually a 'Sound Feedback' switch—just turn it on and you're done. If it's not set from the factory, you might need to connect a programming tool, such as downloading the BimmerCode App and connecting it to the OBD port to activate it. The operation is very safe. Once successfully set, there will be a clear sound every time you lock the car, making it convenient to confirm the anti-theft status. The benefit is that you don’t need to repeatedly press the button to check when parking, making it more worry-free. Additionally, this sound isn’t from the actual horn but a low-volume alarm tone, which avoids disturbing others. It’s recommended to regularly check the settings to keep the car smart. Personally, I feel that setting this up enhances the user experience every time.
