Making a door with proximityprompt that requires to have a keycard in the inventory. ?

Hello everyone, I'm trying to make a door with a proximityprompt that basically requires you to have a keycard in your inventory or else it won't open. I tried to script it but basically it doesn't even open if you have a keycard. Anyone help?

local Door = script.Parent.Parent

script.Parent.ProximityPrompt.Triggered:Connect(function(Player)
    if Player:WaitForChild("Backpack"):FindFirstChild("Access Card") or Player.Character:FindFirstChild("Access Card") then

        script.Parent.ProximityPrompt.Enabled = false

        Door.Door.CanCollide = false
        Door.Door.Transparency = 0.7
        Door.DiamondPlate1.CanCollide = false
