How do you unlock Fortnite Sinister Strip cell?

Fortnite Chapter 7 Season 3: the Sinister Strip locked cell

Epic has added another locked set piece to the Fortnite Chapter 7 Season 3 map, this time tied to a “Locked Prison Cell” inside a building at the Sinister Strip POI.

The cell is part of the season’s trend of “locked” interactables that require a specific unlock approach rather than free loot access. In practice, that means players need to find the relevant prison-cell interior and then use the correct unlocking method the game expects for that location.

Why it matters:

• It adds a new micro-objective to the Sinister Strip area, encouraging repeat visits.
• It fits the season’s broader movement toward map features with gated access (similar to other locked areas and quests across the island).
• It gives completion-minded players a concrete reason to explore interior spaces instead of only looting open structures.

What we know from the coverage

The story specifically identifies the Sinister Strip as one of the season’s POIs and confirms the presence of a locked prison cell within one of its buildings. However, it does not provide additional step-by-step requirements in the text provided here (such as which keycard/item is needed or the exact in-building location details).

If you’re searching, focus on results mentioning “Sinister Strip,” “Locked Prison Cell,” and “Fortnite Chapter 7 Season 3” to find the missing unlock specifics that other guides typically include.
