So far all the places that have been mentioned are the right ones :thumb:
Just hope yours isn't like mine was and the damn stickers were missing. I had to bring it to the dealer and they read the code for me. Good thing i was able to convince the service manager that the guy who sold me the car (3 years ago) told me that they would read it for free since they didn't have the code when they sold me the car. Would have cost like 40 bucks or so to get the code if he hadn't believed me.
Either way you get it i'd suggest you write it down in the owners manual on the page where it explains how to program it since you can use it to reprogram it if you forget the number and it would also be handy for the next owner when you sell the car some day.
