"It looks very important."

The Master Key (マスターキー masutā kī?) is a key item in Resident Evil 2.


This key is used by Leon in scenario B to unlock the door to the B4F security room to fetch Sherry.

It is also used on the panel inside the A-2 Elevator in the Raccoon City Underground Laboratory to reach the B8F platform, on both "B" scenarios.


This key is dropped by Ada in the B2F Power Room after her apparent death by the hands of T-00 during Leon's "B" scenario.

In the non-canon "Leon A, Claire B" game, the key is dropped by Annette in the Main shaft after rescuing Sherry from the T-00 in the B2F Power Room, during Claire's "B" scenario.
