I think I know the answer to this but it was rather strange. (2013 427 original battery). Parked the car about a week ago in the garage, with the battery tender on. There were no starting issues or warnings prior. Tender has had a green light for the last 6 days. Went to start the car today and the door opened as normal, but then I got no start and " No Fob Detected, No Fob Off or Run. Tried the spare fob and same. Pushed the fob buttons and the only one working is the truck release. Had to use the emergency level to open the open to get out. I'm assuming the battery is just not getting enough charge? I'll change the fob battery but think I need a new car battery. Oh, I did put the fob in the glove box slot, and the dash lights all came on as normal, but no start, and got the warnings on fob and others, tract control, service soon etc. Thoughts? Thanks

I bet it's the battery also, the battery tender can show green and good but as soon as you put a big load on it the volts drop right off. I have a Milton load tester and use it every now and then, I've seen same thing you are seeing many times before, it's the battery. Temperature changes etc plus it's 4/5 years old already, that's long for a vette battery! I'd change it anyways at this point .

Have the charging system checked just to make sure its the battery. Chances are the battery is shot.
I replaced my 2013 OEM AC Delco with an Interstate battery last week.

I notice you live in Virginia. But in Florida, perfectly seemingly good batteries go dead in a hurry for no particular reason. The heat I guess.

Also check your terminal connections. I had a loose ground connection once that caused a similar issue. My original battery in my 2012 gave up last fall.
