The Master Key is one of several keys in Granny. It is used to open the Main Door, after all locks are removed from it. It has existed in the game, starting from its release in Version 1.0.
The Master Key
The melon (cut using the guillotine in the Backyard), The car trunk (requires Car Key to be opened), The cogwheel safe (requires 2 Cogwheels and the Playhouse Key), The Kitchen microwave.
The master keys are used only to encipher and decipher keys. Other key-encrypting keys that are called transport keys also encipher and decipher keys and are used to protect cryptographic keys you transmit to other systems. These transport keys, while on the system, are also encrypted under a master key.
It is used to open the Special Lock, which is located in the TV Room, on the wall next to the Clock. Using the Special Key to open this lock will grant access to the Entrance and remove the bars blocking it on both sides. The Special Key only appears if Extra Locks is enabled.
Jail - Behind the Jail Ventilator.
The Hidden Room is a small dirty area that connects the Shed Tunnel and the Basement together. It is also where the Previous Victim left their note. It was added to Granny in Version 1.3.
The Jail Cell can only be accessed using a Weapon, which can either be the Shotgun or Stun Gun. To do so, they have to aim and shoot the Red Button on the wall, through the bars in order to make the set of bars at the bottom slide to the left, allowing the Player to enter the Cell by crouching.
The Master Key's main use is unlocking the Main Door, after all locks, except the Main Door Lock, have been removed from it. Contrary to Master Key's name, it can't open any other locked doors in the game.
There are 2 Unlockable Doors in Granny: Stair Closet door, unlocked with the Remote Control. Sewer - Sewer Cell door, unlocked by shooting the Target Switch.
Usage. The only purpose of the Wooden Stick is to be used as a makeshift lever to activate the Lever Lock and achieve the Pipe Escape in the Spider Cellar.
Master keys and change keys
Change key: This key can open the master lock, but only the master lock. It cannot be used inside any other locks you have. Master key: The master key can open all locks you have in your residential or commercial property.
Master Keying
At a first guess, one may think that this key allows access to any lock on any door. In reality, a master key is a key that can open multiple doors that use the same keying system. These keys can be useful in apartment scenarios, where each tenant has their own key, that opens only their front door.
To do this, you will need to unlock all the locks on the front door and escape. While you are trying to escape, Granny will be looking for you and listening for any sound you make. If she catches you, she will attack you and you will start a new day in the bedroom on the top floor. You only have 5 days to escape.
The Padlock Key is an item in Granny: Chapter Two. It is required for the Front Door and Boat escape routes, but not for the Helicopter. The Padlock Key also has 2 different uses, one for the Front Door Escape and one for the Boat Escape.
Main Door Lock is a regular lock, installed in the Main Door's handle. It can be unlocked with the the Master Key, only after all other locks have been removed from the Main Door.
Open any doors and drawers you see, but do it carefully or granny will hear.
If Granny enters a room where you are hiding under a Bed, she will not notice you and leave shortly after and may also place a Bear Trap. However, if Granny sees you go under the Bed, she will stand by the Bed for a few seconds before dropping down to all fours to jumpscare the Player.
The main reason the Player should come here is for opening the Sewer Cell, which can be done by shooting at the red target with either the crossbow or the shotgun. Granny will never come here on her own unless noise is made.
Its music, that can be heard when Granny plays it from almost anywhere in the House can be used to know her location, meaning in that case that she is currently in the Living Room, playing it. The Player can also tap the tiles of the Piano, if the lid is lifted.
Usage. When sprayed in Granny's face, it will cause her to cover her eyes in discomfort and turn blind for 30 seconds. She will then lose track of the Player and walk away. From here, she will run to sounds that the Player has made, but she will not be able to see and chase the Player themselves.
The Hammer is used for removing planks that serve as obstacles, such as on the main door, in the attic, and in the abandoned area.
The Crow can only be killed by the Shotgun and the ammo, which will leave a few feathers and falls to its death. After that, the Player must be aware that both Granny and Spider Mom will enter rage mode and start chasing the Player after the Crow is successfully killed.
Easier. Extreme is one of the five difficulty options in Granny. It was added to Granny in Version 1.3, and is currently the hardest mode in the game, as it changes various gameplay aspects of Granny.
Depending on the player's choices and escape method, they will receive a different ending. As of Version 1.8, there are 6 endings, the normal ending, the practice ending, secret ending, the secret practice ending, the car ending and pipe ending.
