Programming key fob with only one key? Need help!

[focusonthefocus19]

Where I got my car, they only gave me one key. No spare, and no key fob. I was wondering if my car has it. My car has a sun roof, power locks, power mirrors, and the 6 disk CD changer so it pretty much makes it fully loaded. I put the key in, and turned it 5 times within 6 seconds, and it did made a sound. Which tells me I do have keyless entry.

The thing is I would love, and need a key fob. So since I don't have both keys that came with the car, could I still do it? Will the last owner's second key will be in the system? I just don't get it, lol. I'm sorry. I know how to program it just fine, but kinda stumped on needing both keys part.

I tried to do that with one key and end up finding out it cant be done with out the second key but i did get the key-less entry remote programed you have to take it to the dealer to unlock the computer for you to program the key or a lock smith that deals with cars and has a computer that does the same. Dealer will cost you quite a bit.
