How do i make the item stay in the place and can get by every player without disappearing

Hello, this might be kind of confusing but how do i make the keys or the item stay in that place and the key/item can get by every player one by one without disappearing the keys/item and also the maximum of the key/item of each player is one.

PS. im still new in creating roblox games.

When they touch the key clone it and give it to them. Then next time they touch it make sure to check if they already have one.

Example:

local canTouch = true
myKey.Touched:Connect(function(touchPart)
	if(not(canTouch))then return end --They can't touch it right now
	canTouch = false --Mark they can't touch it
	local humanoid = touchPart.Parent:FindFirstChildWhichIsA("Humanoid")
	if(humanoid)then
		--Is a player/npc
		local char = humanoid.Parent
		local player = game:GetService("Players"):GetPlayerFromCharacter(char)
		
		--Do they already have the key?
		local hasKey = false
		if(char:FindFirstChild("myKey"))then
			--They already have it
			hasKey = true
		else
			if(player)then
				if(player.Backpack:FindFirstChild("myKey"))then
					--They have it in their backpack
					hasKey = true
				end
			end
		end

		--If they Don't have the key give them one.
		if(not(hasKey))then
			local newKey = myKey:Clone()
			newKey.Parent = player.Backpack --put the key in their backpack
		end
	end
	canTouch = true
end)

I’m assuming the key is a tool object.

Simply just make it visible on client do checks to make sure they already havent claimed it and give them it and destroy it after wards the check is fired on server to give them the item.

Is the key intended to be a tool?
