I've found myself stuck out of the office in minus fifteen degrees because the keylock app had stopped working due to a backend upgrade gone subtly bad. Fortunately this was in an urban area and I could find a cafe that was open within the walking distance. I don't know if they allowed pets to thaw in there. It took about an hour for maintenance to open the doors (with a damned key) and let people in.
