Copper Keys in Palworld is one of the few keys that unlock rare chests of the Palpagos Islands. It is used to unlock the glowing red chest that we find during exploration. Unlike the purple and gold ones, they usually do not give you hundreds of coins, but often reward you with Schematics. Bowler Hat and Old Bow are some of the many Schematics that we get from them.

Pal Sphere, Arrows, and various types of consumables are included in the list of items you can get from them. Since Silver and Copper chests have a red glow, you can discover the others while searching; thankfully, these listed methods work for both.

Once you’ve established and built your base, it’s only a matter of time before NPCs and Pals start raiding there. Unless you’ve turned off the switch in World Settings, it’s going to happen often. While it’s tough to defend your camp every time, winning over the enemy is quite rewarding. One of the Pals you’ll attack is Leezpunk, who has a chance to drop both Silver and Copper Keys.

It is not uncommon to collect 3-4 keys after defeating a bunch of Leezpunks. Additionally, you have the ability to capture these Pals while defeating them. Unlock and craft an Alarm Bell to be alerted when these attacks occur.
