Vars | |
| access_id | The access ID of the airlock. Needs to match the variable of the same name from a /obj/item/key_card in order to be opened, unless it's null, in which case it will open no matter what. |

| doorDeni | Given the case of this being used, let's not let door spam be a thing. |
| respects_master_access | Can it be opened with a master keycard? Set this to false if you plan to use it for something that's meant to have only one unique key. |
