The head paladin's keycard is a quest item in Fallout: New Vegas.
Can be acquired by pickpocketing it from the head paladin in the Hidden Valley bunker, who may be either Hardin or Ramos, depending on your choices during Still in the Dark.
The head paladin's keycard is one of the 3 keycards required to start the self-destruct sequence during For the Republic, Part 2, Render Unto Caesar, The House Always Wins, and Wild Card: Side Bets.
- It is advised that you save before attempting to steal the card as you can be caught.
- You can also simply kill Head Paladin Hardin to obtain the keycard, however, this will turn some people in the bunker hostile towards you, even if you're wearing Brotherhood power armor.
- If Hardin is Elder it can be found by pickpocketing Head Paladin Ramos.
