The Green Keycard is an item used to open green doors equipped with glowing green keycard lock.
In some cases, the lock will not be enabled, the player will need to power it by placing an Electric Fuse in a power box and activating it (often located in a different place). To swipe the card, simply left-click.
Green Keycards will lose 25% durability every time they are swiped on a green door access panel, even if the door is already open. They cannot be repaired.
Green Keycards can be sold at the 
Bandit Camp for 15 scraps.
