I removed a card from the script, yet the door is still able to be opened. Help?

I made multiple cards and multiple doors for different levels, but when I remove "L1" from the script, it's still able to be used, but the light still turns red.

if plr.Character:FindFirstChild("L1") or plr.Character:FindFirstChild("L2") or plr.Character:FindFirstChild("L3") then

first door

if plr.Character:FindFirstChild("L2") or plr.Character:FindFirstChild("L3") then

second door

Full Script:

local TweenService = game:GetService("TweenService")
local tweenInfo = TweenInfo.new(1, Enum.EasingStyle.Linear, Enum.EasingDirection.In, 0, false, 0)
local ProximityPromptService = game:GetService("ProximityPromptService")

ProximityPromptService.PromptTriggered:Connect(function(prompt, plr)
    if  prompt.Name == "keycardDoor" then
        local sensor = prompt.Parent.Parent
        local door = sensor.Parent.door
        local Border = sensor.Parent.door.Border
        local Symbol = sensor.Parent.door.Symbol
        if plr.Character:FindFirstChild("L1") or plr.Character:FindFirstChild("L2") or plr.Character:FindFirstChild("L3") then
            sensor.light.BrickColor = BrickColor.new("Lime green")

            TweenService:Create(door.PrimaryPart, TweenInfo.new(2), {Position = door.PrimaryPart.CFrame * Vector3.new(5.1,0,0)}):Play()
            TweenService:Create(Border, TweenInfo.new(2), {Position = Border.CFrame * Vector3.new(0,5.1,0)}):Play()
            TweenService:Create(Symbol, TweenInfo.new(2), {Position = Symbol.CFrame * Vector3.new(5.1,0,0)}):Play()

            wait (3)

            TweenService:Create(door.PrimaryPart, TweenInfo.new(2), {Position = door.PrimaryPart.CFrame * Vector3.new(-5.1,0,0)}):Play()
            TweenService:Create(Border, TweenInfo.new(2), {Position = Border.CFrame * Vector3.new(0,-5.1,0)}):Play()
            TweenService:Create(Symbol, TweenInfo.new(2), {Position = Symbol.CFrame * Vector3.new(-5.1,0,0)}):Play()

            sensor.light.BrickColor = BrickColor.new("Bright red")
        else
            sensor.light.BrickColor = BrickColor.new("Bright red")
            wait(1)
            sensor.light.BrickColor = BrickColor.new("Bright red")
        end
    end
end)
