Ultimate Key
The Ultimate Key (Originally Final Key) is a recurring magical item that can change it's appearance to fit any possible lock. It is necessary to advance the later stages of a game's story, usually by opening a jail door.

Types of Doors

Appearances
Dragon Quest III: The Seeds of Salvation
The Ultimate Key is found at the Final Key Shrine, which requires a mini-quest to be completed in order to enter the shrine.
Location
Acquiring the Ultimate Key is one of the first major tasks the player must accomplish after receiving the ship in Portoga. It requires visiting at least 3 separate locations.
Lanson
The village has an item shop which sells Fading Jennys. These herbs turn the Hero's party invisible for a short amount of time. At least one herb or the spell Fade is needed to proceed.
Edina
The castle is guarded so that outsiders may not enter by normal means. By using a Fading Jenny, the Hero's party can sneak by the sentries guarding the entrance. Inside, there is a boulder puzzle located on the second floor which must be solved. The player must push three boulders around water hazards into a straight line on the north wall. After successfully completing the puzzle, the Hero is rewarded with the Bottomless Pot.
North Central Sea and Final Key Shrine
In the north central sea (just north of where the two peninsula cross each other), there is a small grouping of shoals in a 'T' pattern. By guiding the ship adjacent to the south center shoal, the hero can use the Vase of Drought to raise the Shallows Shrine. Inside the shrine, the final key is located inside a chest.
