Learn about Doom's Keycards and Skull Keys, including Red, Yellow, and Blue variants, and how they open corresponding colored doors.

Keycards or Skull Keys are essential items found in Doom. They can appear as standard keycards or as small skull icons. These keys are color-coded: Red, Yellow, and Blue. Each colored key opens a corresponding colored locked door within the levels. For example, a door with blue bars on its sides is a Blue Door and requires a Blue Keycard or Skull Key to open.

Tips
  • Always check your minimap (a small map displayed on your HUD (heads-up display — the on-screen icons showing health, ammo and the minimap), or Heads-Up Display) for keycard or key locations.
  • Pay attention to the color of the locked doors you encounter and search for keys of the same color.
