USHIN-SHOWA W2.QDJ696 Lost key, Unlocking the entrance door

"Lost key, Unlocking the entrance door"

They seemed to be students from a nearby university. Apparently he lost his keys somewhere in Shinjuku or on the train. Although the property is new, it seems to be a standard thumbturn. It's only for one place on the top, but I checked it properly with the plate and completed it with normal thumbturn unlocking only on the top.
