Use the matching key: Thief’s Key, Magic Key or Ultimate Key. They are not universal keys, so if a chest stays locked after you try the one you have, it likely needs another key. Continue through the story to find the other keys, then revisit chests you could not open.

Why a locked chest may not open

Having a key does not mean you can open every locked chest. The game has three named chest keys, and they are not interchangeable. If your current key does not open a chest, treat that as a likely key mismatch—not proof that the chest is bugged.

The available guide information does not establish a complete list of which individual chests match each key. Try the key you have; if the chest remains shut, keep progressing and return once you have another key.

The three chest keys

Key What to know
Thief’s Key One of the three named chest keys. It is found in a treasure chest in the rental rooms at Pilgrim’s Perdition, according to the indexed Game8 guide: Game8’s Thief’s Key guide.
Magic Key One of the three named chest keys. Its exact acquisition route and chest compatibility are not established here.
Ultimate Key One of the three named chest keys. Its exact acquisition route and chest compatibility are not established here.

These keys are different tools for different locked chests, not a ranking in which a later key is simply a universal upgrade. The available guide excerpts do not verify a chest-by-chest compatibility chart.

Where to find the Thief’s Key

The indexed Game8 guide places the Thief’s Key in a treasure chest in the rental rooms at Pilgrim’s Perdition. The guide excerpt does not establish a floor number, prerequisite or additional interaction, so look through the rental rooms rather than relying on an unverified step.

What to do if the chest still will not open

  1. Try the chest key you currently have.
  2. If the chest stays locked, assume it may require a different key rather than concluding that it is broken.
  3. Continue story progression to obtain the Magic Key and Ultimate Key, then revisit chests that were inaccessible earlier.
