Yellow reactor keycard

The Yellow Reactor Keycard is an electronic security key, color coded yellow.

Location
This item can be found on the body of a dead enclave soldier at the vertibird crash site in Klamath. It would appear to be used to open the respective yellow security level doors in the Gecko reactor, but doesn't open anything. Instead, proper keycards can be found from around the plant, and Electronic Lockpick MKII may also be used on both the yellow and red doors.

Appearances
It only appears in Fallout 2. It does not serve any purpose in the unmodded version of the game. See Fallout 2 unfinished business for details.
