How to Open Locked Doors and Chests in Dragon Quest 2 Remake

Exploring the Dragon Quest II HD‑2D Remake is full of surprises, but one of the earliest challenges new adventurers face is the discovery of locked doors and mysterious treasure chests. Veterans of the Dragon Quest series may already know the trick, yet newcomers often wonder why certain areas remain inaccessible. The answer lies in the game’s unique key system, which gradually expands your ability to explore and collect valuable loot.This comprehensive guide explains how to unlock every type of door and chest, where to find each key, and why these items are essential for progressing through the story. Whether you are a first‑time player or someone returning after enjoying the Dragon Quest III remake, this walkthrough will ensure you never miss an important treasure.

Understanding the Key System in Dragon Quest II Remake

Throughout your journey, you will encounter three distinct categories of locked barriers. Each one requires a specific key, and the game cleverly uses color coding to help you identify which key is needed:

Door/Chest Type	Required Key	Visual Clue
Red Doors & Red Wooden Chests	Thief’s Key	Bright red panels or carved wood
Blue Doors & Blue Chests	Magic Key	Deep blue hue
Silver‑Green Doors & Chests	Ultimate Key	Metallic silver with a greenish tint

The progression of keys is tied to the main storyline, meaning you cannot obtain them all at once. Instead, each key is unlocked at different stages, opening new areas and granting access to rare equipment, powerful items, and hidden lore.

How to Obtain the Thief’s Key

The Thief’s Key is the first special item you’ll acquire, and it marks the beginning of your ability to open locked red doors and red wooden chests. To secure this key:

• Advance the main quest until you reach Moonbrooke Castle.
• Recruit Caradoc, Prince of Cannock, followed by Peronel, Princess of Moonbrooke.
• A sequence involving a lost dog in Moonahan eventually reveals Peronel’s true identity.
• After completing the recruitment, the Chancellor of Moonbrooke rewards you with the Thief’s Key.

This key is crucial for early exploration, granting access to hidden rooms and treasure that strengthen your party during the mid‑game.

How to Obtain the Magic Key

The Magic Key expands your reach even further, allowing you to open blue doors and chests scattered across the world. To earn it:

• First, acquire a ship at Rippleport, unlocking sea travel.
• Collect the Star, Moon, and Sun Sigils from different shrines and dungeons.
• Receive guidance from the Over‑Seer, who directs you to interact with mermaids at Gaggle Rock.
• Defeat enemies such as Belial in the Faerie Palace and obtain Lorelei’s Harp.
• Continue the questline until you meet the Mermaid Queen in Mersea.
• She will present you with the Magic Key as a reward for your efforts.

With the Magic Key, vast new regions become accessible, includingtreasure‑filled sanctuaries and hidden chambers that contain rare gear.

How to Obtain the Ultimate Key

The Ultimate Key is the final and most powerful of the three. It opens silver‑greendoors and chests, many of which contain the game’s most valuable items.To acquire it:

• Progress late into the story until you collect all five sigils.
• Enter the frozen land of Rendarek, the setting for the final chapter.
• Visit the Rendarek Shrine in the northeast corner of the region.
• Speak with the priest inside, who will grant you the Ultimate Key.

Because this key is obtained near the endgame, it serves as the gateway to themost rewarding treasures and secrets hidden throughout the world.

Why Keys Matter in Dragon Quest II Remake

Keys are more than simple tools; they represent milestones in youradventure. Each one not only unlocks physical barriers but alsosymbolizes progression in the storyline. By carefully tracking when andwhere you acquire them, you can avoid unnecessary backtracking andensure you maximize your exploration.

• Thief’s Key → Early‑game progression, useful for building strength.
• Magic Key → Mid‑game expansion, unlocking new regions and rare loot.
• Ultimate Key → End‑game access, revealing the most powerful treasures.

Final Tips for Players

• Always revisit previously explored towns and dungeons after acquiring a newkey. Many hidden rewards are tucked away behind doors you couldn’t openearlier.
• Pay attention to chest colors—red, blue, and silver‑green are your clues.
• Don’t worry if you can’t find the Ultimate Key early; it is intentionally locked behind late‑game progression.
