I've honestly trapped myself outside a bunch of times in the few months I've lived in one of these buildings. Fwiw, Butterfly lets you set up access codes that persist, and so technically if you set one and remember it you can't lock yourself out... but my building's elevators are also fob-locked, so even if I can get into the building, I end up trapped in the lobby until someone's willing to fob me upstairs.
