FOB problems
2006 corvette. I get the FOB not detected message. The car won't start. I placed the FOB in the glove compartment and it still did not recognize it. I have two FOB so I did both of them. I figured it was the batteries. I replaced the batteries and it still did not turn the car on. After numerous attempts at least 45 minutes in a stranded area of trying to get it started before the tow truck came, "Thanks to ONSTAR", it started on its own and I took it to the dealer and they were baffled as well. They finally said it was the starter. They changed the starter and made me purchase a new FOB. I took it home and the car was fine but when I turned it off and tried to restart it, gave me the same error - FOB not detected and it would not start. Same as before, several attempts to start it and it finally did and I took it back to the dealer and of course it started and I could not duplicate the error. Now I am taking it back home. Any one has this situation? It has cost be $1,000 and I still do not have a resolution.

I had a simular problem with my 2007 coupe with the doors not opening because of a bad sensor in the drivers side door. What's confusing is that your FOB's did not work when you stuck them in the slot in the glove box. I was under the impression that would override a sensor issue. It must only be able to override a dead FOB battery problem and so there must be a main sensor or computer problem that controls all the sensors that has a glitch.
I would be curious for my own education as to what it turns out to be so please share. Thanks and good luck!

The glove box issue has me baffled as well. As someone who has just gone through a dead FOB battery problem, I can attest that the car will start with the FOB in the glove box slot. We had to hold the starter button down until the car cranked, but it worked none the less.
Now I am also going to ask you a very stupid question so please don't take offense. Did you have your FOB in your pocket anywhere near or around the immediate area of your cell phone?? I have noticed many times that a cell phone in VERY close proximity to your FOB (probably farther with a weak battery) will interfere and sometimes completely block your FOB signal. So if that was the case I would try it again without the phone nearby.
The dealer was stupid for replacing the starter, if anything they should have started with a new FOB, then move to the sensor that detects the FOB signal. If it says no FOB detected then it has nothing to do with the starter itself. Hopefully some of this can help you. Good luck.

A weak/dying CAR battery would explain the NO FOB DETECTED message. It would also explain why it wouldn't start.
Do you have the original CAR battery? Even if it's new(er), it might be defective.
Or maybe an electrical issue is draining it. If you have a multimeter, it's easy to check. See post #12 at: http://forums.corvetteforum.com/c6-t...ry-issues.html
And: http://forums.corvetteforum.com/c6-c...-problems.html
A marginally-charged battery might not start the car on a cold morning. But it might start as ambient temps warm up.
You might also get other messages and seemingly unrelated symptoms.
More info than you'll ever want to know at:
"HELP! NO FOB DETECTED..."

Were you able to enter the car with the fob? What was/is the battery voltage?
I would surely return the new fob as you a) probably didn't need a new one and b) you should have had two with the car anyway.
The real give away that makes me think low battery voltage is that the car did not start with the fob in the glove box slot. You did, I assume have the orientation of the fob correct, did you not? (glove box transmitter pocket with the buttons facing towards the passenger’s side.)

As evidenced by several here on this forum, when you put the fob in the slot in the glove box, it should start the car, even if the fob battery is completely dead. Sounds like the car battery is about gone.
