Script

local Door = script.Parent.Door
local KeycardReader1 = script.Parent.KeycardReader1
local KeycardReader2 = script.Parent.KeycardReader2
local Open = false

local Level = 3 --The KeyCard Level, anything above this level will also work. Levels are from 1 - 5.

local GrantedSound = Door.Granted
local DeniedSound = Door.Denied
local OpenSound = Door.DoorOpen
local CloseSound = Door.DoorClose

local Levels = {"Omni"}

for i = 1, 5 do
    if i >= Level then
        table.insert(Levels, i)
    end
end

local Debounce = false
function ReaderTouched(Hit)
    if not Debounce then
        Debounce = true
        if Hit.Parent and Hit.Parent:IsA("Tool") and Hit.Parent.Name:sub(1,5) == "[SCP]" then
            local Found = false
            for i,v in pairs(Levels) do
                if Hit.Parent.Name:find(v) then
                    Found = true
                end
            end
            if Found then
                GrantedSound:Play()
                if Open then
                    wait(0.75)
                    Open = false
                    CloseSound:Play()
                    for i = 3,(Door.Size.z / 0.15) do
                        Door.CFrame = Door.CFrame + (Door.CFrame.lookVector * 0.15)
                        wait()
                    end
                else

                    OpenSound:Play()
                    for i = 3,(Door.Size.z / 0.15) do
                        Door.CFrame = Door.CFrame - (Door.CFrame.lookVector * 0.15)
                        wait()
                    end
                end
