Doom: The Dark Ages keys

A number of keys are found in Doom: The Dark Ages. They are used to open gates and doors that are sealed with a matching-colored lock. It is not necessary to interact with a locked door to open it—the lock will open automatically when approached with the correct key in the Doom Slayer's possession.

Keys that have been found in a level are normally displayed at the top of the screen, unless the HUD has been disabled through the UI menu. Keys that have not been picked up are indicated in-game by colored holograms.

Keys[edit]

Keys are found in levels set in Sentinel territories, such as the Village of Khalim and the Abyssal Forest. They come in blue and yellow varieties and resemble pin tumbler keys.

A secret key can be found in multiple levels, and is used to open purple-colored locks that have secrets behind them. The secret key has a spiky appearance and is engraved with a purple rune.

Keycards[edit]

Keycards are found in levels set in Sentinel facilities, such as Hebeth and the Sentinel Command Station. They have a similar appearance to the keycards from Doom Eternal, but have a runic script engraved on them.

Skulls[edit]

Skulls are found in the Harbor of Souls and Reckoning levels. Coming in red and blue varieties, they are large humanoid skulls that have a rune carved into their forehead. The Slayer suit refers to these items as "arcane totems".

Relic key[edit]

The relic key is found and used in The Kar'Thul Marshes. It is made of two halves which are assembled, then placed in a receptacle at the end of the level to open the portal to the Temple of Lomarith.
