After nearly eighteen years of C6 ownership, I finally took delivery of a 2026 Eray this Monday. Much to my disappointment,I couldn't figure out how to lock the fuel filler door.I called the dealership where I purchased the car, and the salesman told me that it was the way it was supposed to be. I told him that even a Toyota Corolla would have a locking gas door. So he went and check the Corvettes in their inventory. He called back later and said all but one of the several Corvettes they had on the lot was the same way. Not being satisfied with that response, I went to a nearby Chevy dealership and did the same thing with a service advisor. Only one of the four vettes in their inventory had a fuel door that locked. To my fellow C8 owners, what has been your experience? Does your C8 have a locking fuel filler door, or not?
The one on my car simply does not lock regardless of what I do. My keys can be fifty feet away with the doors locked and my fuel door will open with a little push.
Something is wrong with yours and you should take it to the dealer. Mine locks/unlocks with the doors. I can hear it unlock when the doors unlock and also hear it lock when I lock the doors with the remote. Mine works just as mentioned in post #7.

I checked your 2026 Owner's Manual. You fuel door is supposed to lock. If its not working as described in your manual, then its broke.
Thank you for your comments. I took my car to the dealership and I was told that my car didn't have that option. It's a 3LZ, BTW. I'm going to attach the result from my visit below. That might explain why most of the 2026 Corvettes in the dealers' inventory exhibited the same result. They showed me by physically locking the cars with the fob then stowed the fob away at a distance so the doors are locked. The fuel doors would still open with a push. They proved to me that my car is not a one off. When I built the car, there was no mention of this as an option.

Looks like another feature quietly removed from the 2026 model year (like the rear window defogger grid removal from coupes). Disappointing...

Well, that's that I guess. But......
Did the dealer check your build data to see if that code is there? The fact that something has an option code does not necessarily mean its an extra cost option. There are lots of standard equipment features that have option codes - they should show up in the detailed build data.
That clip you posted is from a 2026 Service Manual. That language was not in the 2020-2022 Service Manuals, but it did appear in the 2024 Service Manual. So its had an option code for at least 3 model years (2024-2026).
A while back there was an issue with DRLs not coming on properly in the daytime. And, it was consistent across a batch of vehicles so if one checked other cars they would have concluded that it must be working right. In fact, it was a defect - it was a batch of ambient light/sunload sensors that produced an out of tolerance voltage, failing to trigger the DRLs. So checking other cars, while a very strong clue, is not 100% conclusive. The memo though seems to clinch it.
I looked this morning for any evidence of it being an extra cost option - in the specs on the Chevrolet website and I don't see it. So it may be just deleted and not available.
I checked an RPO code list and found this:
N04 : LOCK CONTROL, FUEL FILLER CAP, REM CONT
N05 : LOCK CONTROL, FUEL FILLER CAP
N06 : LOCK CONTROL, FUEL FILLER DR REM CONT
N08 : LOCK CONTROL, FUEL FILLER DR REM CONT
N09 : LOCK CONTROL, FUEL FILLER DR
I found it curious that the TB4 is optional. That code was more elusive but I found a list that includes it:
TB4 24691 P BDS M BODY EQUIPMENT LIFT GATE (MANUAL) 960920
So, I don't think that refers specifically to the locking feature for the lift gate - it would appear to be the code for manual liftgate on the coupe I suppose.
The explanation you posted came from a Service Manual for 2026. So, I looked for the equivalent wording in the earlier LEMON manuals to see if/when it became an option. The result is pretty interesting. Here is the language in the 2020-2022 version - with no mention of RPOs.
The 2023 is missing from the list of LEMON manuals - but the language is changed in the 2024 version, now showing the option code. The point being its been an option code since 2024, but as far as I know, no one reported the issue until now in the your 2026 model.
