The Omega Key is the first of the magical keys created by the Locke family, designed to control access to the Black Door. Forged from Whispering Iron in 1775 by Benjamin Locke, it is the oldest key of its kind in existence.

Benjamin Locke forges the Omega Key and its lock

When Benjamin Locke was hiding in the caves with the revolutionaries, they accidentally opened the Black Door allowing the Children of Leng to escape. Once Benjamin realized that regular steel was insufficient to hold the door closed, he crafted a padlock and key from Whispering Iron which proved sufficient to hold the door shut.[2] Later, the lock was modified to be part of the door itself.[3]

In 1915, Chamberlin Locke locked the Omega Key along with several other keys in the Vault of Shadows to prevent his son, John Locke from using them to turn the tides of World War I.[4]

The key was only used to obtain Whispering Iron, and no infestation of the Children of Leng was recorded until the Tamers of the Tempest made their attempt to open the Black Door.[5] After the events of that attempt, Rendell Locke vowed to ensure the Omega Key would stay hidden for the rest of his life.[6]

When Dodge returned, he started hunting for the Omega Key, which had been concealed in the urn containing the cremated remains of Rendell.[7] After the urn was shattered, Tyler and Kinsey Locke rediscovered the Omega Key. Tyler attempted to hide the Omega Key in his head using the Head Key, but when he was infected with Kinsey's Tears and Fear, his siblings opened Tyler's head to remove them and Dodge (in Bode Locke's body) found the Omega Key, removing it when the others were not looking.[8] Dodge used the key to open the Black Door, and had selective demons infect various students during the Locke after-party in the Drowning Caves.[9]

After Dodge's defeat, Tyler kept the Omega Key on a keychain, with most of the other keys.[10]

Netflix Adaptation[]

After witnessing the portal that was opened by Captain Frederick Gideon and the danger that had come out of it, Benjamin Locke seeks to seal it behind the Black Door and to use the Whispering Iron from a demonic bullet that narrowly missed him and his sister to make the key. However, Benjamin's attempts fail until Miranda recalls that in alchemy, one must have both intention and sacrifice. By adding his own blood to the molten metal, Benjamin succeeds in crafting the Omega Key and sealing the portal behind the Black Door. His success and the Whispering Iron on the cave floor peaks Benjamin's interest into what other kinds keys he can make.[11]

In 1988, the Keepers of the Keys use the Omega Key to open the Black Door, resulting in Lucas Caravaggio getting possessed by the demon Dodge.[12] The other Whispering Iron that was left behind when the door was opened is later used by Duncan to create the Memory Key.[13]

When the Keepers split up the keys, Rendell takes the Omega Key[12] which he subsequently hides inside of his own head using the Head Key. After Rendell's death and cremation, it ends up in his ashes where it's later found by Tyler and Kinsey Locke.[14]

After the apparent defeat of Dodge, the Savini Squad uses the Omega Key to send the demon back through the Black Door, although Eden gets possessed in the process. Unbeknownst to them, it was actually Ellie Whedon that they had sent through the door, disguised as Dodge with the Identity Key.[15]

When the Lockes toss all of the keys into Gideon's portal, Tyler tosses in the Omega Key. It is the last key to be thrown in and the portal closes behind it.[16]


The key is the only key able to open the Black Door. Other than this, it also follows the intent of its creation and prevents any other key from opening the way to the Children of Leng. Any attempt to open the door using other keys will just open into an empty room.[3]
