Strange starting problem.....
One strange thing occured that I didn't think about until I got home was that I had both FOB's togather on a single key chain and that FOB 2 took over, but not enough to allow the car to start. FOB 1 should have taken control per the owners manual, if both FOB's are present. At any rate, either the FOB didn't pass all that it was suppose to pass or the car did not receive all the FOB's transmission-as to which is the smoking gun remains unclear with the Service Rep to contact BG this morning.

I think you are getting closer and closer to the "smoking gun".......the next step I would try is stop using fob 1 altogether and go strictly with fob 2.......see what happens........maybe you've done that already.
Push start button
fob computer sends message to fob
fob replys back
fob computer, body computer, and column computer talk and unlock column
column computer verifies column unlocks, if not, B2515 sets and the vehicle will not start because the column is still locked
if everything is ok, the vehicle starts
I would think that if it were a fob issue a code would set in the BCM or FOB computer, B2515 would not have set if the column computer did not get the message to unlock and fail at it. The message would never have been sent if the fob was not detected.
Was you column locked or unlocked? The only other thing I can think of is some kind of theft detterent, passwords are passed between the column computer, the fob computer, and the engine computer. The manual says that a DTC will set if the engine computer doesn't see the right password, I'm not sure what happens if the fob and column one's don't match. If they didn't match, I think you'd get the issue nearly all the time and probably would not have set a B2515, since the column computer would be not unlocking the column on purpose.
My bet is that there is a problem with the column lock itself.

It may be now, the car wouldn't start last night after work for nothing. Even taking the negative off the battery would not reset the system or unlock the streering column. I called up the Rep and said the "car is DOA, Battery is okay, the FOB is in the Left Rear Wheel, it needs to towed, and I won't be there" Lucky for me the wife was only a few miles away and picked me up, the downside(along with the rest
) I realized with a DOA and the fact the streering column won't unlock, the C6 will be a bitch to flat bed out of a crowed parking lot!To answer your questions, Nope never saw a No FOB Detected message in the DIC. From the standpoint of FOB security, I would make the assumption that there is several bits of data that must be passed prior to the car starting- offhand the FOB should be passing it's MAC address (a unique hardware addess) and a programmed in password. With these two forms of ID, car theives may be able to hack the MAC, but unlikey the password. The door system most likely only uses one of the code elements. While the steering lock may be the problem, the programming may have not accounted for a unsual security situation and allows the signal to the steering column lock dispite the the unlocking is unsupported-who knows
All I know is my fun meter is pegged out with this situation.
Talking with the Service Rep, they are replacing the steering column lock bits and looking to replace the Dash receivers and FOB's with a recent upgraded set if it applies to my car type-the person in charge of the receivers is not returning the Service Reps call(s) so that's a question that is still open. However, I am going to be firm about replacing the receivers and FOB's regardless since I still think the problem begins at that spot. My steering column parts are being sent to the Great White Mid West to be put on a Z51 MN6 to see what it does up there, but I am given to understand this electrical snafu is becoming more of a problem around the country. The last statement may have been fluff, but they do seem to want to fix my problem. And so it goes, if all the parts come in, I'll have the car tomorrow-pray for me
The Best of Corvette for Corvette Enthusiasts
when this is finally resolved! 
With no end in sight for these maybe repairs, and with the car in the shop now for 25 days, together with 4 trips to the dealer, and one towing experience, we called "our" GM Customer Service Representative, Mr. John Brooks, to begin the process of either exchanging the car for one that works, or our going to the Florida's Attorney General's Office and Better Business Bureau to begin the Florida Lemon Law Process to force the exchange. Given the cars' repair history, there is only marginal resale value given the increased CARFAX report popularity and demonstrated history of poor reliability of this 2005 C6 Corvette.
At first Mr. Brooks conceded on his own that the car should be replaced and that he would check it out with the "higher up" who hasn't returned his phone call yet, but in Mr. Brooks' return call this afternoon the story changed to there would be no replacement since there was a "fix" in the works. A "fix" which is only speculation at this moment, without any meaningful C6 2005 Corvette parts support from Chevrolet, and without even a likely estimate of time when the so-called "fix" will be completed.
Needless to say, we filed with the Florida's Attorney General's Office & Better Business Bureau right after Mr. Brooks phone call. It really sucks when your dream car turns in to your nightmare.
I love my car, 0 issues so far at 9,XXX miles, I only wish everyone's experience was as good as mine...
My local dealer was able to find those part numbers rapidly, they are below, though I didn't ask for a part number for an entire column assembly:
88963405 Column Lock
10353066 Steering Column Lock Module

In any case, since I have not heard anything from the Service Rep, I take it that the parts are coming by slow UPS ground which is going to place the final repairs, if successful, well out of the 30 day grace period. Concerning the FOB's and Transceivers, had I not seen what I and the Service Rep saw, I would doubt its' role too, but it without any doubt does have some role in the problem. However, is it bad-probably not, rather I suspect it was just poorly installed which is not an uncommon event for any assembly plant-Bowling Green or otherwise. I know for a fact, that Active Handling and Traction Control was not operational until the Service Rep went through the wiring, and getting the Service Rep to dive deep in to the dash was an attempt to effect a similar affect.
With the order of FOB's, it is in both the owners manual and the owners DVD that when both FOB's are present that the system defaults to FOB #1-from a programmers stance, that defaulting is both logical and needed when both FOB's are equally detected during the Memory Recall process. Order of FOB's should have no affect on whether the car is allowed to start-what got my attention is the process used #2 when both FOB's were on the same key ring-that's likely FOB battery levels verus signal strength.

i had the same problem right around 900 miles and the worst part is it was infront of 2 police officers after chatting with them for about 20 minutes about the C6, it fixed itself and thats the last time that every happened to me and i just hit 2000 miles

Well we broke down and called the Service Rep Friday night and asked how it was going with the repairs. He stated the parts came in late Friday, and the car would be repaired by Monday afternoon. The Rep stated that he was not to discuss any details with us, and that he has been called many times by GM'upers in the last few days. I hope they are treating him well, because he has been one of the best people to work with and I have become very impressed with his abilities & near terminator desire to get the car fixed right-so no matter how this all plays out-he's the only one, other that me, who is ever going to work on my car.

They cost a little more but are the same as what GM dealerships use.
So are you picking the car up today or just leaving it at the dealership while pursuing the buyback? Your whole ordeal sucks....glad to hear your dealer has been friendly...
Good Luck
