About the Blue Keycard

Each swipe on a matching card reader costs it 1 condition, so a fresh one is good for 4 swipes; a reader of another color costs nothing.

It also lies at fixed spots in 4 monuments: Ferry Terminal, Harbor, Satellite Dish and Sewer Branch. Gutting Catfish, Orange Roughy, Salmon and Small Shark can also give one, at 20% each time.
