Laboratory Keycard

The laboratory keycard is a miscellaneous item in Fallout: Brotherhood of Steel. It gives access to the Secret Vault's laboratories.

Background
Rhombus, along with his men, entered Los and stole the Vaults' main laboratory keycard from a cult organization. He and his men fought the cult, but lost to them, so he was captured and taken to Los' torture chamber near the docks and was tortured by Blake for the location of the stolen keycard. Having hidden it under a truck, Rhombus later assists the Initiate to its location. Once in destination however, he is blown up by a ghoul suicide bomber.

Unable to continue fighting, he gives the Initiate the keycard and entrusts him with the task of stopping Attis' army and finding the Secret Vault entrance.

In the Residence hub, the keycard is taken from the Initiate again by Attis, right after Defeat Mutant General.

Characteristics
Key to enter the Secret Vault - Laboratories.
