Aftermarket Remote Central Locking

Hi guys,

I'm looking to get a remote central locking system for my 2003 3door Polo. Its already got the standard all round central locking and immobilizer, but it would make my life a lot easier if I could have a remote fob to activate my existing central locking system.

Thing is, I don't even know where to start for this project. I'd need all the kit obviously, and the cheapest places to get it installed.

If anyone could offer any advice I'd be extremely grateful!
