It's kinda weird that Quentin finds the newspaper in the basement for no reason. This suggestion is to make the ending of day 1 cooler and more creative.
Instead of there just being 1 room in the basement, there should be a room off to the side. In that room should be a pinboard, like Mr. Peterson's in the AS. One of the articles there is the Museum closure newspaper. You'd be able to rip it off the board and inspect it, then turning it around you would find the key taped to the back that unlocks the bunker door outside.
