Maybe I can add to this thread? My FOB is detected inside the car so that it starts. However, it isn't always detected to open the door from the outside. When I press the open door button, the doors open and then for a while, the FOB works as intended. The car is a 2014. I'm thinking I need to replace the FOB battery. Do I just split it open with a small screwdriver? I'm also worried the FOB won't work again after I replace the battery.
Any suggestions?
Thx

The OM shows complete procedure to change fob battery using the rounded end of the key to open case.
Make sure the fob is warm so as to not crack the plastic.
The OP's scenario sounds like a possible RF interference problem, or the car battery is starting to go south. Don't know if the OP put the fob in the slot on the steering column or not (and if so, did it work?).

Always take key out of pocket when this occurs. I know this sounds stupid but my cell phone interrupts my key fob from being detected ..not all the time but it happens more than I would have believed possible.
Obviously I'm not sure what your scenario is but for me...when my car doesn't detect the fob as shown on dash I just take my fob out of my pocket which usually has my phone in the same pocket...the car starts right up.
Hope this helps.

I know it's a longshot but try replacing the fob battery again. I had this issue with my C6 and the new fob battery I replaced it with did the same thing. But I had gone the cheap route and bought the battery from a dollar store, and when I got a proper Energizer battery the problem was solved.

The car is a 14, I'd replace it. Many corvette owners know that when you start having unusual electrical problems its almost always a battery issue. Make sure your battery cables are tight (which I think you said they were).
My 14 battery went bad at 2 years 2 months.

Recently had a problem with my main FOB that I had changed it's battery 1 1/2 years ago on my 3+ year old C7. At first it required hitting the open door button from time to time. Then one day I got a "FOB Not Detected" signal and had to put it in the column slot to start.
Took both FOB's apart and tested the batteries with a battery tester that puts a load on the battery to get an accurate reading. It has an analog scale reading Weak and Good. Both batteries read into the good area but just on the "G" in Good. Checked a new battery I had and it read to the 2nd "O" in Good. Put it in and all was fine. That was a month ago, all still fine.
Note, I also used a pencil eraser and cleaned the contacts when I put in the new battery-definitely worth doing.
PS: Never stranded, can always use the removalble key to open the hatch, pull the cable on the left wheel well to open the door and start the car by putting the FOB in the column slot.

Well, there is a way to figure out the issue.
