I bought a key fob off ebay which had the exact same numbers as my current key fob. I finally get it and am having an *** of a time getting it to sync with my car. I only have one key right now and was just going to use this as a spare remote incase I lock my keys in the car. With that being said I can't have one key in the ignition and one in the door to program the key fob as I found in some forums that I searched.

I've tested the battery in my working remote and it works just fine. Starting to run out of ideas and think I may have to go down to the dealership. Can anyone give me a hand?
