The line comes from a PewDiePie gameplay video, where Felix Kjellberg voices the kind of small, everyday confusion that made his early let's play commentary popular. Clipped from longer footage, the question circulated on soundboards and in fan edits as a standalone reaction rather than as part of a specific story moment. Its appeal is its universality, anyone who has played games knows the locked door problem, so creators reuse it across gaming, meme and reaction videos without needing to explain the original context at all.
