The Underground Key is a story item. It's a copy of the Big, Metal Key.

The underground key can be found on the decapitated corpse of the Trader lying next to the broken air compressor in Hideout 4 after the first night, or in a grave next to the Old Shed. The corpse is initially buried completely, but the grave can be dug open with a Shovel that has at least 50% durability remaining.

Trivia

This key could be the reason why the Trader's helmet is scratched with the word 'liar'. He tells the Protagonist that there's no way out of the woods, even though he carries the exact same key that the Protagonist had and needs to escape.
