When a tool touches a part, it teliports player?

This script I made is that when this tool touches a part, it teleports the player to another map, but when the tool does touch the part, nothing happens. I think the script needs to be inside the tool, but the problem is that I do not know how to define it, Here is the script that I have so far that is inside the tool where the player clicks on to pick the tool up (If something does not make sense comment)

local player = game.Players.localplayers
local humroot = player.Character.Humandrootpart
local teleport = game.Workspace.Store.teleport
local db = false
script.Parent.Touched:Connect(function(Key)
    if Key == game.Workspace.bedroom.Door then
        if not db then
            db = true
            humroot.CFrame = teleport.CFrame
            wait(1)
            db = false
        end
    end
end)

Thanks for reading!
