Keycards

Description
Some doors require a Keycard to open it. There are levels 0 through 5, a higher number meaning better access. The card color can be used to identify its level.

Tips

 * Use SCP-914 to upgrade your card
 * Level 4 is the best for escaping, as it gives you access to everything but the nuke.

Trivia

 * Chaos Insurgents use Chaos Chips instead of Keycards.
 * Level 0 is actually the rarest, it is unkown if you can downgrade a level 1 janitor keycard to a level 0 the only other way is to find it in the class d cells
 * Even if you have a Level 5 Card, you cannot open SCP-079's Room
