Keys are items found in Wolfenstein 3D that, once picked up, enable the player to open locked doors. There are two colored keys: gold and silver. Once a key is picked up, it is shown in the player's HUD and may be used to open any number of locked doors, but only ones that correspond to the type of key picked up.

Trivia

Be cautious, though, that you don't let the door close while you're on the other side if you intend to come back. You'll be trapped, unless you can find a Key or get another enemy to open the door. To avoid this situation, kill the enemy while he stands in the open door - it'll never close.
