The Master Key is a key in Granny. It was added in Version 1.0 and will get the Player out of the house once all the other locks are taken off. However, this isn't the only way the Player can escape, as he/she can fix the car and escape by driving the car through the Garage Door as of Version 1.5.
The Master Key is used to unlock the Main Door's regular lock after all other locks have been taken off. It cannot be used anywhere else.
AppearanceThe Master Key is composed of a handle and a blade. The handle is hexagonal in shape with a narrow rectangle shape cut out near the center of the handle. It is red in color (although this may be due to lighting). The blade is silver, which would be what you would expect as the blade seems to be made of metal. It has 4 grooves along the blade.
The Master Key can spawn in these four locations:
- Car Trunk (requires Car Key to open) Preset 1
- Inside the Melon (use the Guillotine to break open) Preset 2
- Inside the Cogwheel Safe (requires Cogwheels to unlock) Presets 3 & 4
- Inside the Microwave Preset 5
- Despite its name, it can only unlock the Main Door. This is misleading as the name "Master Key" implies that it can be used on every lock, when it cannot even open Locked Doors.
- Unlike all the other items required to open the door, you must use the Master Key last.
- If the player tries to open the door without all the locks taken off, a message will say "I cannot open this door yet".
- Without the Master Key, however, it says "i need a master key"
- This item used to be the most important item until Version 1.5, where the Player can escape by using the Car in the Garage. Therefore, the Master Key is not as important as it used to.
- Just like the Padlock Code and Battery, this item is not required to escape anymore as the player can use the car escape method.
- It used to spawn in the Safe, the Bathroom right Sink and in the Study wardrobe.
