Hello Neighbor 2: How to Get All Museum Keys

After Act 1, Hello Neighbor 2 revolves around getting further and further into the Museum. Each act may begin in a different location, such as the bakery, Otto’s house, or the Mayor’s mansion, but they all end in the same place one way or another. And if you’re here, you’re wondering how to get all the Museum keys. 

Indeed, Hello Neighbor 2 is as much about hunting down keys as it is uncovering nefarious plots and escaping the clutches of angry townsfolk and a kidnapper. Everything you do serves the mechanic of finding one more key to open one more door. Collecting them all will take you from the beginning of Act 2 to near the end of Act 4.

Though you’ll be able to visit and explore the Museum at the end of Act 2, you won’t get all of the keys you need to fully explore it until Act 4. What’s more, Peterson locks almost all of the doors again in Act 5, and you won’t have any of the keys to open them again from that point forward. Here’s how to escape the final boss and complete the game.
