This can be done by disabling the horn prompt sound in the personalization settings. The method to turn off the locking horn sound is as follows: 1. Press the "Settings" screen button. Rotate the MENU button (located on the light control lever, not available in low-end models) and select the "Vehicle" option. Five options will appear: "Air Conditioning and Air Quality," "Lights and Door Locks," "Remote Key," "Collision Warning," and "Restore Factory Settings." 2. Select the "Remote Key" option. Remote Lock Feedback: Change the feedback type when remotely locking the vehicle. Choose among options such as "Lights and Horn," "Lights Only," "Horn Only," and "No Feedback."

I've been driving a Buick for several years, and the beeping sound when locking the car can indeed be quite loud, especially when returning home late at night and not wanting to disturb the neighbors. The method to turn it off is actually quite simple: press and hold the lock button on the remote for three to five seconds, and you'll hear a short confirmation sound, indicating that the mute function has been activated. If holding the button doesn't work, or if your Buick is a model with a central control screen, you can start the car while sitting inside, then navigate to the 'Vehicle Settings' or 'Security Settings' in the screen menu, and select the 'Sound Alerts' option to turn it off. Remember, this sound is originally intended as an anti-theft reminder, so turning it off reduces some security. It's recommended to use this feature only in quiet areas. Also, don’t forget to check the vehicle manual for alternative methods and ensure the car lock system is functioning properly to avoid any issues in case of emergencies.

Hey, as a Buick owner, I often run into this situation, like wanting to keep it low-key in the neighborhood without the beeping noise. Turning off the sound is super easy: just take out the key fob, press and hold the lock button until you hear a soft beep, and you're done—it takes less than ten seconds. For newer Buick models, you can also do it via the central console: start the engine, navigate to the settings in the vehicle info screen, find the sound management section, and simply turn off the lock confirmation sound. This feature is originally designed as a security measure for anti-theft alerts. While turning it off is convenient, be extra mindful of your surroundings to avoid missing a failed lock attempt. Also, get familiar with the button feel to avoid damaging the remote and save yourself the hassle of replacing it.

I use a Buick for daily commuting and feel that the loud locking sound might disturb my child's rest. I found it easy to turn it off: first, press and hold the lock button on the key for a few seconds until the beep appears; second, open the car's infotainment system and adjust the sound options in the settings to disable the alert. It's recommended to check the owner's manual before proceeding to avoid mistakes, as the sound is originally for anti-theft purposes—turning it off means you'll need to confirm the car is locked yourself. A simple maintenance step is all it takes.
