Resident Evil 2 Diamond Key Location And The Doors It Opens

28 September 2026 | 141

Navigating the eerie corridors of the Raccoon City Police Department in Resident Evil 2 requires careful exploration and efficient item management. Among the various keycard and key items scattered throughout the building, the Diamond Key stands out as an essential tool for unlocking crucial supplies. Locating this key helps players acquire valuable ammunition, weapon upgrades, and inventory expansions.

Where to Find the Diamond Key in Resident Evil 2

The Diamond Key is located in the basement level of the police station inside the Morgue area. Players must navigate through the basement corridors past the Parking Garage and Kennels to reach this chilling room. Once inside the Morgue, locate the cold storage body drawers along the wall.

Pull out the second cold drawer from the left on the north side of the room to reveal a corpse. The Diamond Key sits directly beside the head of the body on the cold slab. Be prepared for a fight, as retrieving the key causes nearby zombies to reanimate immediately.

Doors Unlocked by the Diamond Key

Once acquired, the Diamond Key opens several key areas across the police station basement and upper floors. In the basement area, it unlocks the door to the Firing Range, granting access to helpful items like handgun ammunition and a locked tin box. It also grants access to the Elevator Controls Room in the basement for players controlling Claire.

On the second floor of the police station's west wing, the key opens the Linen Room located near the S.T.A.R.S. Office. Inside the Linen Room, players can collect valuable gunpowder as well as a Portable Safe containing a spare keypad key. Unlocking these doors provides a significant advantage for surviving the survival horror challenges ahead.

Tips for Managing Keys and Inventory Space

Because inventory slots are strictly limited in Resident Evil 2, knowing when to carry or store the Diamond Key is vital. Once you have unlocked every corresponding door marked with a pink diamond symbol, a small checkmark icon will appear on the item in your inventory. This checkmark indicates that the key has fulfilled its purpose and can be safely discarded to free up space.

Plan your routes carefully so you can visit the Firing Range and Linen Room in a single loop before returning to a safe room. Securing the supplies behind these locked doors ensures you remain well-equipped for tough encounters with Lickers and Tyrant. Efficient backtracking ensures you make the most of every item found in the police station.
