Keycards

Keycards are a major and necessary element of the game, as being the only item in-game that can open doors with a keycard slot. Keycards can be found in various places. There are six keycard levels, from 1 to 5 plus Omni.

Level 1
The level 1 keycard is the lowest level card. It can open the first door to the small testing chamber.

The keycard can be found in:
 * The storeroom.
 * A storage room affected by SCP-970.
 * The 2-level office, next to a computer.

The keycard can also be created by putting a quarter into SCP-914 on the "Fine" setting.

Level 2
Level 2 keycards can be used to open the doors to SCP-895's chamber and SCP-914's chamber.

The keycard can be found in:
 * The basic office.
 * The small testing room.

The keycard can also be created using SCP-914 by putting a level 1 keycard in it on the "Fine" setting, or a master card or quarter on the "Very Fine" setting.

Level 3
Level 3 keycards can be used to open:
 * The main door in SCP-012's chamber.
 * SCP-079's chamber.
 * SCP-205's chamber.
 * SCP-966's chamber.
 * All the doors in the SCP storage chamber.
 * The first door in Containment Room 5.
 * The surveillance Room.
 * All the doors in the server hub.
 * The checkpoint room between the Light Containment Zone and Heavy Containment Zone.

The keycard can be found in SCP-895's chamber. It can also be created by putting a level 2 keycard into SCP-914 on the "Fine" setting.

Level 4
Level 4 keycards can be used to open:
 * The head office.
 * SCP-106's chamber.
 * The two doors to the lower area of SCP-106's chamber.
 * Both doors in SCP-008's chamber.

The keycard can be found in SCP-049's chamber.

Level 5
The level 5 keycard is the highest keycard that can be obtained. Both can access any rooms requiring a keycard.

Level 5 keycards can be used to exclusively open:
 * SCP-035's chamber
 * The door to the elevator leading to the warhead room as well as the door leading into the small control room inside.
 * The checkpoint room between the Heavy Containment Zone and Entrance Zone.
 * The blast door to reach Gate A.

The keycard can be found in SCP-106's chamber under a shelf beside the controls and in the head office. It can also be created by putting a level 4 keycard into SCP-914 on the "Fine" setting.

Omni
The Omni keycard can access anything requiring a keycard, making it equivalent to a level 5 keycard. The Omni keycard can only be obtained via placing a level 5 keycard into SCP-914 on the "Fine" setting or with any level keycard on the "Very Fine" setting, though this has a chance of creating a MasterCard instead.
