Keycard system for doors not working?

Im trying to make a tweenservice based door that requires a keycard to be scanned before it opens. I have a system with the keycard item where it has values in each keycard for each door it can open, However my code isn't working.

Ive tried everything I can think of to fix it.

Doors Code:

script.Parent.Scanner1.ProximityPrompt.Triggered:Connect(function(plr)
	local Keycard
	for i,v in ipairs(plr.Character:GetChildren()) do
		if v:IsA("Tool") then
			Keycard = v
			break
		end
	end
	local Swipe = plr.Character.Humanoid.Animator:LoadAnimation(anim)
	local Access = Keycard
	if Access.GeneralAccess.Value == true then
		plr.Character.HumanoidRootPart.CFrame = CFrame.new(POS1) * CFrame.fromEulerAnglesXYZ(0, math.rad(90), 0)
		plr.Character.HumanoidRootPart.Anchored = true
		Swipe:Play()
		wait(2)
		plr.Character.HumanoidRootPart.Anchored = false
		DoorOpenTween:Play()
		script.Parent.Scanner1.Light.Color = Color3.fromRGB(131, 89, 255)
		wait(3.5)
		script.Parent.Scanner1.Light.Color = Color3.fromRGB(255, 89, 89)
		DoorCloseTween:Play()
	end
end)

Error: **Workspace.GeneralDoor.Script:41: attempt to index nil with 'GeneralAccess' **
