Pirates of the Caribbean: Dead Man's Chest (2006) revolves around finding the chest which contains Davy Jones' heart. Central to the story is finding the key which unlocks the chest.

Jack seem to have acquired the information as well as a diagram of the key. Based on which he puts together a crew and sets on the journey.

Key to Davy Jones' chest

My question is if Jack had the diagram why didn't he got a duplicate made from a key maker?

Is there any supernatural element involved in the original key because it was never explained in the movie?

    Sometimes, a McGuffin just has to be there, otherwise there's no plot ;) If he'd just wandered down to the local mall to get a key cut, then straight off to Isla Cruces, the movie would have been a whole lot shorter.

  • As far as we know, the Key and Chest's maker/origin remains unknown: pirates.fandom.com/wiki/Key_to_the_Dead_Man%27s_Chest Jan 31, 2021 at 15:00
  • @Tetsujin: I understand your point. But isn't it so obvious. In a universe where Pirates rule the sea how hard was it to dupe a key.

    How do you know that the key is precisely copied? How do you know if it's to scale? How certain are you that the key hole is cylindrical?

1 Answer 1


I think the unique design of the key combined with the fact that there was magic involved stopped Jack from duplicating or making a new key. He had the "drawing of a key" and theoretically could have had somebody make one for him, but again: A McGuffin does have to be there,if it begins to exist. I think maybe Jack didn't know anybody to make a key or even didn't trust anybody to make a key, which is more likely. Or the lock could have been imbued with some sort of magic? It's unclear, but I think most likely Jack didn't trust anybody to make him a copy without telling Davy's men. Jack Sparrow trusts nobody, not even himself.

  • While I would agree with anyone that we don't have a ton of evidence still to prove anything, I think this answer is logical and attempts to cover most of the bases. I do think Flater also makes excellent point about the diagram may not be to scale, but I also think your one point about the key being "magical" makes a whole lot of sense too. 1+ Aug 2, 2021 at 12:35
