Convert Deprecated Keyboard Input Into UserInputService?

Simple and easy, but I would like a good thorough way of converting this script into UserInputService. I gave an attempt, but I don't think it worked at all, lol.

Original Script:

local Tool=script.Parent
local V=script.Parent.HandValue.Value
local keys={false,false}
local debris = game:service("Debris")

--[[
(- Example -)
function Key(key)
    if (key=="o") then
        Tool.Movement.Disabled = true
        Tool.GripPos = Vector3.new(0, 0, 0)
        wait(0.05)
        Tool.Movement.Disabled = false
    end
end
]]


function Key1(key)
 if key then
  key = string.lower(key)
  if (key=="e") then
   keys[1]=true
   repeat 
    if script.Parent.PowerValue.Value <= 90 then
    script.Parent.PowerValue.Value=script.Parent.PowerValue.Value+5
    else
    script.Parent.PowerValue.Value=script.Parent.MaxValue.Value
    end
    wait(0.1)
   until keys[1]==false
  end
  if (key=="q") then
   keys[2]=true
   repeat 
    if script.Parent.PowerValue.Value >= 10 then
    script.Parent.PowerValue.Value=script.Parent.PowerValue.Value-5
    else
    script.Parent.PowerValue.Value=script.Parent.MinValue.Value
    end
    wait(0.1)
   until keys[2]==false
  end
 end
end

function Key2(key)
 if key then
  key = string.lower(key)
  if (key=="e") then
   keys[1]=false
  end
  if (key=="q") then
   keys[2]=false
  end
 end
end

function selected(mouse)
 mouse.KeyDown:connect(Key1)
 mouse.KeyUp:connect(Key2)
end

script.Parent.Equipped:connect(selected)

Attempted Converted Script:

local function onInputBegan(input,gameProcessed)
    if input.UserInputType == Enum.UserInputType.Keyboard then
    if input.KeyCode == Enum.KeyCode.E then
    if script.Parent.PowerValue.Value <= 90 then
    script.Parent.PowerValue.Value=script.Parent.PowerValue.Value+5
    else
    script.Parent.PowerValue.Value=script.Parent.MaxValue.Value
    end
    wait(0.1)
    elseif input.KeyCode == Enum.KeyCode.Q then
   repeat 
    if script.Parent.PowerValue.Value >= 10 then
    script.Parent.PowerValue.Value=script.Parent.PowerValue.Value-5
    else
    script.Parent.PowerValue.Value=script.Parent.MinValue.Value
    end
    wait(0.1)
end
    end
    end
end
