How to make the key value not "InputObject"?

I am trying to create a thing for a gun and you are supposed to press r to reload but when an input has been given, it sees it as "InputObject" Here is the local script:

local service = game:GetService("UserInputService")
service.InputBegan:Connect(function(key)
    if key == Enum.KeyCode.R then
        game.Players.LocalPlayer.Character:FindFirstChildOfClass("Tool").Reload:FireServer()
    end
end)
