Tracking down your father is your top priority in Five Night at Freddy's: Into The Pit. He's been taken to the past and you must find a way to bring him back. One of the objectives is to enter a locked arcade.
FNAF Into The Pit Part 1 – PIT SPRING BONNIE IS LOOKING FOR ME..
The arcade is locked off from the two entrances you can reach if you go to the past, at Freddy Fazbear's Pizzeria. The only way into the arcade is to find a key, but there are no clues as to where to find it. Here's what you need to know about how to get into the arcade in FNAF: Into The Pit.
The trick to finding the arcade key is via an item you unlock during the day. You need to use the Sticky Hand that you stole from the principal's office when you were in school. Take it to Freddy Fazbear's Pizzeria in the past and go to the Party Hallway. This was the same area where you had to lure the bird out of the kitchen to save the other kid in Into The Pit.
You'll want to avoid the wandering animatronics as they try to find you at Freddy Fazbear's Pizzeria. You can be sure to encounter at least one of them as you explore the Dining Area. When you reach the Party Hallway, head to the right of this location and you should see a small shiny object on the top of a cabinet. Approach this area and interact with it using your Sticky Hand.
