I see this as a design flaw. My current car blasts the horn every time I lock the doors. My prior car (German of course) did the same, but it had a 2 stage horn and the one for locking the doors was a more pleasant, softer tone. I hate that when I lock my car late at night somewhere the horn blasts but I have little choice because of the way it was designed.People who can't lock their cars without blowing the horn. Especially if you are walking right in front of the car when the horn blows.
