Programming key fobs on 2008 G6?

I just had to replace the battery in my 2008 G6 with the 3.5L motor. I think it's the first time since I bought the car new, that I've ever had to disconnect the battery. I installed a new battery. Now, the key fobs don't work. I checked the fuse and it is fine. I called the dealer and they said that the car can sometimes lose the programming for the key fobs when the battery is disconnected. But they offered to reprogram it for $30 per key fob! So, any time I ever have to disconnect the battery in the future, I can expect to pay GM $60 to reprogram these stupid things? I found stuff on this forum and elsewhere on the internet on reprogramming the FOB. I spent an hour in my driveway inserting and removing the key, turning the car on and off, opening and closing the door, etc. I'm pretty sure that stuff is just on the internet to piss me off and make me look like a jackass in my driveway.

This is the key fob with the remote start option. Thoughts?

Unfortunately the only way to program the fob for your car is to go to a dealer. How long did you have the car disconnected? I've disconnected my battery numerous times without problems, but being disconnected for a prolong period of time may cause it to loose the programming.

Well, we drove the car last Friday. Then, it sat all weekend. We were lazy and didn't go anywhere. Monday, my wife called me at work and told me her car was dead as a door nail. I took the battery out to get it replaced. I wanted an Interstate battery, but they were out of them until today. I took the old battery back to the car, jump started it and it's been okay until today. I could tell that it was weak. I replaced it today with the new battery. Still, the fobs don't work. When I had the battery totally out of the car, it was out for about four hours.
