Navigating through the eerie corridors of the Rhodes Hill Care Center in Resident Evil Requiem presents survival horror fans with several intricate brainteasers. Among these challenges, opening the locked safe in the East Wing stands out as a crucial milestone for story progression. Understanding how to locate key items and interpret subtle clues will ensure you open this container without unnecessary backtracking.

Locating the Office and Essential Prerequisite Items

The Lead Researcher's Office is situated on the second floor of the care center's East Wing, offering a brief respite with its integrated save point. Before attempting to solve the symbol puzzle, players will notice that the puzzle box itself is secured by an impenetrable padlock. Standard tools will not break this lock, meaning you must first locate a bottle of corrosive liquid to dissolve the metal barrier.

To acquire the corrosive, navigate down the main corridor while avoiding dangerous enemies like the patrolling Chunk boss. Head toward the conference room area to retrieve the level-one wristband and pick up the corrosive bottle off the table. Once secured, return to the office safely and apply the liquid directly onto the padlock to reveal the symbol dial.

Deciphering the Step-by-Step Clues

Investigating the environment inside the Lead Researcher's Office provides all the clues necessary to deduce the proper code. Careful observation of the framed photographs scattered around the room reveals hidden details within their backgrounds. Each image depicts care center directors alongside specific celestial symbols representing the input sequence.

By arranging these visual hints in chronological order based on the dates on the portraits, the correct sequence emerges naturally. The required celestial symbols consist of stars, suns, and moons that match the interactive dials on the box. Players who study these environmental details can confidently bypass trial-and-error guessing.

The Correct Code Combination and Solution

If you prefer to skip the deduction process and immediately open the container, the symbol sequence follows a specific four-step pattern. Input the symbols in the exact order of Star, Sun, Moon, and Sun to trigger the unlocking mechanism. A distinct mechanical click will confirm that the puzzle box has been solved successfully.

Entering this combination correctly unlocks the safe door instantly without requiring extra resources or safety risk. Make sure to input each symbol carefully on the dial interface to prevent resetting the mechanism. Completing this step allows Grace to secure vital progress items necessary for escaping the facility.

Rewards Obtained and Next Progression Steps

Opening the puzzle box grants players two invaluable items that drive the central narrative forward. The primary reward is the Sun Quartz, which is the second of three essential gems needed to unlock the Central Hall main door. Placing this key item into the central gateway brings you one step closer to reaching the courtyard area.

Additionally, you will receive the Leatherbound Notebook containing crucial instructions for secondary objectives. This document explains how to unlock the organ transport box located inside the care center's lower garage. Retrieving the artificial organ from that box becomes vital for solving later puzzle mechanisms deeper within the research facility.
