The Key Guardian can be found in two Granite towers in the ⏣ Jungle. It is guaranteed to drop 1xJungle Key. It respawns every 1m 50s if there is a moving player in the area.

Tips[]
One of the easiest ways to kill the Key Guardian is to place blocks at its spawn location before it spawns, which makes it suffocate. Damage from suffocation inflicts 1/20 of its maximum health every 0.5s, and it still drops the key(s) even if it is not killed by a player, as long as the player hit it at least once.
The Key Guardian is considered a zombie, so the Reaper Falchion and the Revenant Falchion could be some good choices for early game players trying to obtain a key.
It is possible to spawn multiple Key Guardians at the same time if more than one player is near the spawn location, effectively increasing the number of keys.
It is only possible to deal 50,000 damage to the Key Guardian per hit, so ⫽ Ferocity or high Bonus Attack Speed is useful. A strategy also commonly employed is a Guardian Pet and Fire Veil Wand, since hitting an enemy causes the Guardian Pet to attack and the Fire Veil Wand "procs" every 10 ticks, (every 0.5s).
Trivia[]
If the 1m 50s respawn cooldown is up, a new Key Guardian will immediately spawn as soon as a player moves nearby, even if they were not moving before.
Farming these mobs for Jungle Keys and selling them on the Bazaar is an efficient way to make money.
It is possible for both Key Guardian towers to generate in one server. This allows players to mine a path between the two and kill both for more keys.
