Central locking
 

I have recentley bought a Hyundai Atoz 2000 but have only been given 1 key with it and I think this was the spare. I think the car had central locking fitted originally but without remote key fob, this is difficult to tell. Can anyone please let me know if there is a way of telling if the car has central locking fitted. Also cheapest way to get spare key cut as I understand they have a chip built-in to start car. Thanks
