Open a Lock using a Key, and a Safe in a single match is one of Fortnite's Chapter 3 Season 4's weekly challenges.

A Fortnite challenge asks you to open a lock with a key and a safe in a single match and this guide will show you how to complete it.

In the last Fortnite update v22.10, Holo Chests were added to the map. Much like the game's Vaults, they require keys to open and contain loot of varying rarity.
