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.

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.

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.
