My hover car code is not working and I can't find out what's wrong with it?

local NullVector = Vector3.new(0,0,0)
local player = game.Players.LocalPlayer
local speed = 20
local rotend = true
local moveend = true
local pos = script.Parent.CarStat.Value
local rot = pos.Parent.BodyAngularVelocity
local uis = game:GetService("UserInputService")
uis.InputBegan:connect(function(input)
	local keycode = input.KeyCode
	if keycode == Enum.KeyCode.W then
		moveend = true
		moveend = false
		pos.Velocity = pos.Parent.CFrame.lookVector*speed
		repeat wait() until moveend == true
		pos.Velocity = NullVector
	end
	if keycode == Enum.KeyCode.S then
		moveend = true
		moveend = false
		pos.Velocity = (pos.Parent.CFrame.lookVector*-1)*speed
		repeat wait() until moveend == true
		pos.Velocity = NullVector
	end
	if keycode == Enum.KeyCode.A then
		rotend = true
		rotend = false
		rot.AngularVelocity = Vector3.new(0,-10,0)
		repeat wait() until rotend == true
		rot.AngularVelocity = NullVector
	end
	if keycode == Enum.KeyCode.D then
		rotend = true
		rotend = false
		rot.AngularVelocity = Vector3.new(0,10,0)
		repeat wait() until rotend == true
		rot.AngularVelocity = NullVector
	end
end)

uis.InputEnded:connect(function(input)
	local key = input.KeyCode
	if key == Enum.KeyCode.W or key == Enum.KeyCode.S then
		moveend = true
	end
	if key == Enum.KeyCode.A or key == Enum.KeyCode.D then
		rotend = true
	end
end)

I already made the script that turns the car on when you sit in it. This localscript is put into the player that is sitting in the car. That works just fine but the Localscript (above) is not working nor is it raising an error to help me debug the problem. I need someone else who can easily spot errors to help me. I have no clue what's wrong.
