Access Powers

Access Powers is an unmarked quest in Fallout: New Vegas.

Detailed walkthrough
Obtain Jenny Millet's security keycard at the end of the REPCONN tour given by the tour guide robot and use it to access the first computer on the left of the locked door from the reception room. Then head up to the second floor and find another computer to obtain further access.

Find all three keycards, take the Q-35 matter modulator from behind a locked (100 Lockpick skill to open) door. There is also a wall terminal (100 Science to hack) next to the door that can be used. Then read all terminal entries and deactivate the robots without firing a shot or being caught by security robots without the correct security clearance.

Bugs
If you hack the computer to create a third floor keycard or loot the third floor keycard from the suitcase on the third floor the security robots will not recognize you as a legitimate person on the third floor unless you have Luck 7.

Behind the scenes
The name of this quest is a play on the phrase "Axis Powers."
