Keycard

Information
Keycards are helpful items in SCP-Containment Breach, they allow the player to open keycard-locked doors.

Behind the keycard-locked doors are usually helpful items allowing the player to finish the game so it is recommended to use keycards, although keycards can help you finish the game quicker it is possible to finish the game without the use of keycards.

Kaycards

Level 1 - Level 1 keycards are useless keycards since they can only use the door to the 'Electrical Center'.

Level 2 - Level 2 Keycards can be created by placing a Level 1 Keycard through SCP-914 on 'Fine' although this is impossible to do ingame since level 2 keycards themselves are required to open SCP-914's containment chamber. They can be found in the 'small office' and the 'testing room'. Level 2 keycards are used to open SCP-895 and SCP-914's containment chamber.

Level 3 - Level 3 keycards are used to open many more SCP containment chambers like SCP-714, SCP-106 and SCP-1025. They can be created by placing a Level 2 keycard through SCP-914 on Fine.

Level 4 - The Level 4 keycard is the highest keycard that can be used to complete the game (this means the player does not need to require any more further keycard levels). It is created by placing a Level 3 keycard through SCP-914 on Fine but they can also be found in SCP-106's and SCP-049's chamber. They are used to open the 'head office' both doors to SCP-008's chamber and the lower level door to 'SCP-106's containment chamber.

Level 5 -  The level 5 keycard is required to open the door to the elevator leading to the warhead room,  the door leading to the small control room in the warhead room and the door in the checkpoint room between the Heavy Containment Zone and Entrance Zone. It can be found in the head office or obtained by placing a level 4 keycard through SCP-914 on Fine.

Omni - The omni keycard is not needed to be obtained ingame since the level 4 keycard can be used to complete the game but if the player chooses to obtain it the only way to do so is place a Level 5 keycard through SCP-914 on Fine. The omni card can open all doors around the facility.
