FOB problem
I just got a clean 2008 after selling my 2000 C5.
FOB is neat.
When I press the button on the inside of the door, the red light flashes so I think the door contacts are good; but one out of ten times the door does not open. I press the lock and unlock buttons on the FOB and the car eventually recognizes it and everything works. Sometimes pressing the lock and unlock don't do the job and I have to press to open the trunk. The FOB buttons work from easy 40 feet away so it seems that the battery is good. Any suggestions.
I know - replace the battery - but I want to understand first. I thought that FOB recognition was passive RDIF and did not require and battery.

No fob reprogramming is required when replacing either the car battery or the fob battery.
I'd replace the fob battery and see if that helps. If not, get someone who knows how to check the car battery.

Congrats on your new C6! 
1. Like Jim says, replace the fob battery. Some tips:

2. Cell phone in the same pocket? It might be causing intermittent interference.
3. Do you know how to get into your C6 with a dead fob battery? Lots of reports of difficulty using the metal key the first time, so try it and make sure it works. See pg 2-15 in the owners manual: http://www.gmpartshouse.com/download...08corvette.pdf
4. Make sure you know how to use the glovebox slot. See pg 3-62 in the manual.
