As you advance through the storyline of Dragon Quest 3 HD-2D Remake, you’ll need to gather three different types of keys to access new regions in the game world. Your journey will often be interrupted by Red Doors, Blue Doors, and Prison Doors, which require the respective keys to unlock. Collecting each key not only reveals new treasures but also aids you in progressing through the narrative.
The three keys you can find during your adventure are the Thief’s Key, Magic Key, and Ultimate Key. Each one serves a unique purpose, allowing your party to unlock specific doors found in various locations. Many of the best weapons and items in DQ3 Remake are hidden behind these special doors, so it’s beneficial to collect all the keys for both exploration and story progression.
How to Obtain the Thief’s Key
Open Red Doors Using This Key
Some updates to the plot in DQ3 Remake from the original title won’t become apparent until you acquire the Thief’s Key from the Dreamer’s Tower. This location is on a distant island in the far western part of the map, accessible by traveling underground. To reach Dreamer’s Tower earlier in the game, navigate through the Promontory Passage tunnels.
After reaching the top of the Dreamer’s Tower, you can claim the Thief’s Key from a sleeping elder located on the fourth floor. Fortunately, you won’t need to battle any bosses to obtain it; simply speaking to the old man will suffice for your party to receive the key.
By unlocking a Red Door, you can recruit your first friendly monster for the Monster Arena. Forming a team of three monsters that you’ve gathered can unlock numerous rare rewards as you battle through the Arena.
Here’s a list of all the areas where you can use the Thief’s Key to open Red Doors:
- Underground Water Supply
- Aliahan Castle
- Reeve
- Little Shrine
- Path of Promise
- Khoryv
- Portoga
- Nordy’s Grotto
- Kidnapper’s Cave
- Edina Castle
- Fifer’s Spire
- Pirate’s Den
- Ghost Ship
How to Obtain the Magic Key
Climb the Pyramid to Unlock Blue Doors
The Magic Key can be found on the third Basement floor of the Pyramid, a dungeon filled with numerous enemies. NPCs in the Asham region can provide hints about the Magic Key’s location, which lies to the west of the main map. Unlike the isolated island for the Thief’s Key, this quest will lead you to a vast desert housing the Pyramid dungeon.
The Pyramid is located near the desert city of Ibis, which is situated southwest of the desert. The dungeon is directly north of Ibis and features seven challenging layers. Prepare yourself for an array of traps, puzzles, and formidable foes as you seek out the Magic Key.
The quickest route to the Magic Key involves falling through one of the Pyramid’s floors to drop down to its basement levels. Be cautious of traps in the narrow hallways that lead to the stairs connecting the various floors.
When you arrive in the Basement, press a button located on the far right of the first floor and another on the far left of the second floor. Activating these buttons will unlock a door on the third Basement level, where you’ll face a boss guarding two treasure chests. One of these chests contains the Magic Key, which you can start using right away on Blue Doors throughout the world.
Here are all the locations in DQ3 Remake where Blue Doors can be found, accessible only with the Magic Key:
- Aliahan Castle
- Romaria Castle
- Romaria Checkpoint
- Asham Townhouse
- Pyramid
- Ibis Castle
- Kidnapper’s Cave
- Alltrades Abbey
- Edina Castle
- Manoza
- Castle of the Dragon Queen
How to Obtain the Ultimate Key
Unlock All Remaining Doors
The Ultimate Key is needed to unlock Silver Doors, which you can find in the Shallow Shrines by using the Bottomless Pot to elevate the area. To get the Ultimate Key in DQ3 Remake, your team must first obtain the Bottomless Pot, which you need to steal from Edina, located to the northwest of the map on an isolated island similar to where the Dreamer’s Tower is situated for the Thief’s Key.
You can utilize spells like Fade from magic users to make your party invisible to Edina’s guards, facilitating your acquisition of the Bottomless Pot. Alternatively, items like a Fading Jenny can also provide concealment.
Before you can acquire the Bottomless Pot, you must solve a puzzle hidden beneath Edina Castle. This involves maneuvering various rocks onto different pressure plates to unlock the relic. After securing it, head to The Shrine of the Dwarf, located between the northeast and northwest continents. To reach the Shrine, navigate the ocean separating these lands.
Once at the Shrine, you will have the option to drop the Bottomless Pot into the ocean. Selecting “Yes,” will transport you to the Shallow Shrine underwater, where you’ll find a chest containing the Ultimate Key. With the Ultimate Key, you can now unlock any Silver Door in the following locations:
- Aliahan Castle
- Shrine of the Plains
- Romaria Castle
- Romaria Checkpoint
- Portoga Lighthouse
- Theddon
- Lanson
- Olivia’s Promontory
- Wayfarer’s Inn
- Pirate’s Den
- Manoza Castle
- Wayfarer’s Capital
- Shrine of Shackles
- Baramos’ Castle
- Tantegel Castle
- Talontear Tunnel
The Ultimate Key is a crucial item needed to confront the final boss of the game, Baramos. Don’t forget to gather orbs that are necessary to awaken the Everbird as part of your journey. Retrieving the Ultimate Key from the Shrine of Shallows is less daunting than traversing the Pyramid, as there are no bosses to defeat in the process.
By unlocking all the doors in Dragon Quest 3 HD-2D Remake, you will uncover a variety of treasures that greatly aid you in the fight against Baramos. Be sure to take the time to unlock all doors when you have collected all the keys, as this will empower your party with the best items available in the game.
