Last night I dreamed all the locks started updating themselves

I'm walking through a city where every door has a screen instead of a keyhole. They keep flashing 'update required' and then locking people out while the progress bar crawls. I'm the only one carrying a handful of brass keys that don't fit anything, but nobody asks me for help—they just keep tapping the glass. The weirdest part: I wasn't even annoyed, just tired, like I'd seen it all before.
