keyless entry
 

I have a 2006 grand prix and I was wondering what I need and what needs to be done to have keyless entry. The car didn't come with a key fob so does that mean that I can't have one or is it just a matter of getting one and having it progammed for my car? If someone could give me a complete run down of what i need to do to make this possible that would be great. Thanks.

Also I've seen several remotes with remote start. How do I know if my car is equipt with that? I assume I can probably tell by looking at the vin number so if someone could clue me in on that as well please. Thanks again.
