Why aren't electronic door locks common in the United States?

I've seen comments on various subreddit like "Lock the door well for safety" and "Unlocked houses are mainly subject to theft." Also in my short memory, houses and apartments often used the door key.

Why don't they just use the electronic lock? It locks automatically. It'll be a bit of a problem if the battery runs out, but those locks start to sound off at least a few weeks in advance when they run out of power (every time when we open and close the door), and they last at least a few months once they're plugged in.
