Key Code (GF)

Key Codes (as named in the level objects data) are password terminals in Metroid Prime 3: Corruption. They are seen twice in the game, both times on Olympus-class battleships: Docking Bay 4 on the G.F.S. Olympus, and the Control Room on the G.F.S. Valhalla. The former occurs at the beginning of the game and is mandatory for progress, while the latter is later on into the story and optional. To progress, a five digit passcode must be entered. Each number pressed will be replaced with a minus (-) symbol as no number can be used twice. Once the full code has been implemented, an enter key beside the numbers will flash green. Once pressed, the code will be accepted if entered correctly. If a mistake is made, the B button on the Wii Remote can be pressed to exit Context-Sensitive Mode and restart. The actual codes to use these terminals are found within the room.

In Docking Bay 4, Samus is required to enter her Federation login Key Code terminal to access the Security Station, where she will be scanned for any biohazards before attending a meeting in the Ready Room. Before she can type in her code, she must scan the terminal. Her personal code, 13576, is found on an Information terminal directly behind her. After using it, a voice says "Access granted" and a Blast Shield on the Door to the Security Station is lifted.

In the Control Room, the terminal does not have to be scanned. The code, 78356, is found on a dead Federation Marine's PDA and when entered into the terminal, reveals a video message from Aurora Unit 313 explaining what happened to the Valhalla and that it is being abducted and transported to the "source of all Phazon", later revealed to be Phaaze. The message cannot be heard again, but produces a Friend Voucher for "Secret Message Discovered".

Aurora Unit 313 message
"Data log entry 2467.3. This will be the last communication of the G.F.S. Valhalla. Our efforts to repel the Space Pirate boarding force have failed. They have successfully removed the primary mounting structure around our stasis tank. It is obvious now that they intend to extract us from the Valhalla. It is vital that the Federation receive this transmission.

Trivia

 * In Metroid: Other M, Samus is seen typing a longer password with letters and presumably numbers into a computer in the Bioweapon Research Center. The only letters that can be made out of this password are "EYK". When "Madeline Bergman" types in her password, only "OT4" can be made out.
 * Pirate X-Ray Pads are also named "Key Code (SP)" in the objects data, like the Federation password terminals. However, these terminals are much different, requiring the X-Ray Visor and a complex password consisting of Space Pirate symbols to pass.
