Unlocking the Magic: A Guide to Locke & Key’s 12 Enchanted Keys

If you had magical keys, would you use them to do good, get back at someone, or do something impossible that’s possibly life-threatening? Locke & Key, the long-awaited television adaptation of the best-selling comic book series by Joe Hill and Gabriel Rodriguez for IDW comics, explores the moral dilemma about the use of power for good versus evil.


After their father is murdered under mysterious circumstances, the three Locke siblings and their mother move into their ancestral home, Keyhouse, which they discover is full of magical keys that may be connected to their father’s death. As the Locke children explore the different keys and their unique powers, a mysterious demon awakens — and will stop at nothing to steal them. From Carlton Cuse (Lost, Bates Motel) and Meredith Averill (The Haunting of Hill House), Locke & Key is a coming-of-age mystery about love, loss, and the unshakable bonds that define family.


Throughout Locke & Key, the siblings discover new keys hidden in Keyhouse, each imbued with a unique magical power that bends the confines of reality. When creating the keys in the comics, Hill and Rodriguez were careful to make sure each new key would ask a question and add to the narrative. The producers mirrored that logic. “The keys represent one of the most important themes for our show: Identity. Each of the keys has the power to change you or your world in some way,” Meredith said.

Here’s a guide to Locke & Key’s 12 enchanted keys. If you had the power to use each one of them, would you? More importantly, should you?


The Anywhere Key allows the holder to transform any door into a portal to any location. As long as the holder has a clear vision of the destination in their mind, the Anywhere Key can take them there.


The Head Key enables the holder to create a door into anyone’s mind. They can walk into their own brain and see its inner workings — and bring others along, too. This key also allows the holder to extract things from the mind (memories or emotions) and insert things (books or false memories).


The Echo Key can conjure an “echo” of a dead person — a ghost-like apparition who looks and sounds like whoever has passed on. It is also the key to the wellhouse. The apparition remains confined to the wellhouse.


When used to open the correct door inside Keyhouse, the Ghost Key allows whoever steps through it to leave their body and travel as a ghost around the Keyhouse grounds. Their soul rejoins their body when they reenter Keyhouse through the same door.


The Matchstick Key can immediately ignite any surface it touches.


The Mending Key can fix broken items placed inside the mending cabinet used with the Mending Key.


Brand new to the Locke & Key universe, the Mirror Key opens a doorway to the prison of the self. When used in a mirror, the key will show you the mirror realm version of yourself, meant to lure you inside. If you’re not careful, the Mirror Key can trap you and anyone who ventures inside in an inescapable labyrinth of mirrors.

The Omega Key is the most mysterious of the keys. It opens the Black Door located deep inside the sea caves near Keyhouse. It unlocks access to another dimension.
