Can Someone Help Me With My Keycard System?

In my place, I'm using keycards to open doors. However, it's not working as I want it. I'll add notes in the script to tell you as I go along.

Group = 1015675
Key = script.Parent.Keycard

function ForgeKey(LevelToPrint, Player)
    NewKey = Key:Clone()
    NewKey.Parent = game.Players:FindFirstChild(Player.Name).Backpack
    Folder = script.Parent.CardProperties:FindFirstChild("Level "..LevelToPrint)
    NewKey.Handle.BrickColor = Folder.Colour.Value
    NewKey.Handle.Reflectance = Folder.Reflectance.Value
    NewKey.Level = LevelToPrint
end

game.Players.PlayerAdded:connect(function (plyr)
    plyr.CharacterAdded:connect(function (char)
        if plyr:IsInGroup(Group) then
            Rank = plyr:GetRankInGroup(Group)
            if Rank < 50 then
                ForgeKey(1, plyr)
            elseif Rank == 52 then
                ForgeKey(3, plyr)
            elseif Rank < 200 then
                ForgeKey(2, plyr)
            elseif Rank == 202 then
                ForgeKey(4, plyr)
            elseif Rank < 253 then
                ForgeKey(4, plyr)
            elseif Rank > 252 then
                ForgeKey(5, plyr)
            end
        end
    end)
end)

Anyone see where I faltered? Thanks in advance.
