In the third act, the golden key can be found behind the door that it unlocks, though there is an alternate path to that room the player must take.
In the second act, the key can be found in the room above the child's bedroom, and allows for a shortcut back to the fireplace room nearby. In order to get the key, the player must remove the nearby oversized painting and jump through the hole it covered. In the first act of the game, the golden key unlocks a door on the second floor of the house, and the key itself is next to that door. To turn off the electromagnet, the player must visit the roof and, using the red gramophone, navigate past the tomato plants and drop an object into the hatch covering the gears. It can be found attached to the electromagnet in the room next to the tram station at the top of the ladders. The green key allows the player to unlock the first floor door near the stairs that takes the player to the Fear School level. In Act Two, it is on a wall hook next to the door it unlocks.
It's only required for unlocking an easier path to the third floor and train car. It requires the magnet gun in order to be obtained. It can be found on the second floor, in a cabinet behind the painting. The blue key allows the player access to the room on the 3rd floor containing the crowbar and the platform which takes them to the Fear Supermarket level.
