This building is located in the south-west of northern Freeside. To get to this area coming from the north, enter Freeside via the north gate, walk past the Old Mormon Fort and head under the broken highway (on your right) towards the city wall. This is in the same area as the ruined store (where NCR troopers are handing out free meals to NCR citizens, also where the Courier goes for the quest G.I. Blues). Keep walking past the ruined store, down the roadway, and a small gap in the piles of concrete opens up to the character's left. Head through this gap and directly ahead and slightly to the right is the building.
The building consists of several rooms spread over a single story. The building is inhabited by giant rats and broken protectrons, as well as the sexbot Fisto, controlled by a terminal requiring a 50 Scienceskill to unlock.
The Cerulean Robotics key is found in the room to the right of the entrance. It's on the floor in the southern corner of the room between the couches, in the hand of the skeleton near the TV. This key unlocks the tool cabinet, found in the north corner of the building, containing the terminal access card. The terminal access card is used on the "Protectron Programming Interface Terminal" if the player doesn't have 50 Science skill. The terminal is used in the Wang Dang Atomic Tango quest to program Fisto.
If you have the Wild Wasteland trait, as you leave the building you are attacked by three old women, Maud's Muggers, armed with rolling pins, knives and switchblades. They sometimes spawn as you get to the door, without you having to enter the building.
