Fortnite Chapter 7 Season 3 is packed with hidden secrets, but one of the easiest to miss is the Rubber Duck keycard. Tucked away at Cluster Coast, this item unlocks a secret vault filled with valuable loot, giving players another reason to explore this point of interest.
Unlike other vault keys in Fortnite, this one doesn’t spawn in a fixed location. To get inside, you’ll first need to track down the Rubber Duck keycard by searching the various rubber ducks scattered around the Cluster Coast. Most of them are harmless decorations, but one suspicious-looking duck with sunglasses holds the keycard that unlocks the secret vault.
