How do i put a specific tool into players?

So i want to put a specific tool into players but how would i do that

this is what i got:

for i,v in pairs(game.Players:GetChildren()) do 
	if (v:IsA("Key card")) then 
	v.Parent = game.Players.LocalPlayer.Backpack
	end
	end
	wait(0.5)

Put the item in StarterPack which you want every player to have, and when they join they will get given whatever you put in StarterPack. You are over complicating it.

Hi, there are several problems with your existing script, first its a local script which makes the tool invisible to others & and since it is there is no use for using i, v in pairs(). Second of all, you do if (v:IsA("KeyCard")) then. There is no roblox part called KeyCard, you would have to use "if v.Name == "KeyCard" then. Third of all, a tool cant be a member of players So do this and it should work

local keycard = game.Workspace.Keycard
for i, v in pairs(game.Players:GetChildren()) do 
if v:IsA("Player") then
keycard:Clone().Parent = v.Backpack
end
end
