In Palworld, you may have come across Copper Keys when exploring the world.
It’s basically used to unlock certain chests that you can find.
Here’s where you can use the Copper Key in Palworld.
How to use Copper Key
You’ll come across Copper Keys early on in the game, probably from opening regular chests.
Once you have the key, you can look for another type of chest which is red in color.
You’ll find this chest right at the ruins where you first begin the game. Go into the ruins / castle and look for the chest which is hidden inside it.
Open it with the Copper Key and you’ll get some items including arrows and gold coins.
