Key — minecraft

This feature is exclusive to Java Edition.

This article documents an April Fools' joke.

This feature was exclusively part of a joke version and is not currently planned for addition to regular Minecraft.
It is documented here on the wiki due to being officially-released content by Mojang Studios, even if not present in a final version.

Keys were a joke item from Java Edition 3D Shareware v1.34. There are three different keys: red, yellow, and blue.

Obtaining

Mobs

The red key was dropped by the wither, the yellow key was dropped by ravagers, and the blue key was dropped by the elder guardian.

Trivia

A key with a similar appearance is present in The Europa Arcology Incident, a game made by Notch in 2009.
Likely a reference to doom (1993) which also had similarly colored keys, and a shareware version.
