How to make this part perfect in players hand?

Hey fellow ScriptingHelpers users, Im making a Piggy style game and Im making it to hold only one item per person and this is my keycard script (All others keys are perfect with same script but with different math) and no, ffs not making those parts tools as it would break the "concept" of the game.

local key = script.Parent

script.Parent.ClickDetector.MouseClick:Connect(function(player)
	local char = player.Character

	if char:FindFirstChild("Chave") then
		local oldKey = char:FindFirstChild("Chave")
		oldKey.Parent = workspace
		oldKey.WeldConstraint:Destroy()
		oldKey.CFrame = key.CFrame * CFrame.Angles(0,math.rad(45),0)
		oldKey.CanCollide = true
	end	
	
	if char:FindFirstChild("Martelo") then
		local oldKey = char:FindFirstChild("Martelo")
		oldKey.Parent = workspace
		oldKey.WeldConstraint:Destroy()
		oldKey.CFrame = key.CFrame * CFrame.Angles(0,math.rad(45),0)
		oldKey.CanCollide = true
	end	

	key.Parent = char
	key.CFrame = char.RightHand.CFrame *  CFrame.Angles(math.rad(180), math.rad(22.427), math.rad(-232.931)) --The math it uses

	local weld = Instance.new("WeldConstraint")
	weld.Parent = key
	weld.Part0 = key
	weld.Part1 = char.RightHand
	key.CanCollide = false
end)

try pushing the keycard by putting a invisible part and the key card will be pushed i think i haven't tryed it cuz idk how lol.
