| ||For the Fallout and Fallout 2 items, see pass key.|
In Fallout 3, pass cards are items that are randomly encountered. The cards serve no purpose and can be sold to any merchant without drawback.
A ghoul has 1.5% chance of dropping a pass card of either color. A centaur has a chance of 0.6% and trogs have an even smaller chance of about 0.4%.
