My seat arosa mk1 came with central locking and i added remote locking kit to it that was easy enough as long as you look at what wires you need found on this forum, or someone else can probs help. But there are kits that will work like this one; http://www.extremeautoaccessories.co.uk/products.php?section=1225 Not sure how easy it is to install but you could then also add a kit like the one i have to it to make it remote locking. The one i have is this one; http://www.in-car-stuff.com/shop/falcon-phaser-remote-central-locking-upgrade-p-32.html Not in stock here but there is some on ebay, I got mine from this site they are good. Good luck with the central locking!
