I'm a bit of a noob but where do you buy the transmitter from and how do you program it yourself? You buy it from the dealer, also some Locksmiths stock them and can code them in for you too, generally for cheaper and quicker than the dealer offers. What car do you need the programming instructions for? I have a 2007 Aurion Sportivo and want a spare transmitter. I'll check out a few locksmiths and see how I go. Thanks
