Click, doors locked again! The hidden key was my savior in this case as it had been on other cars over the years.

When I returned home I checked the voltage on the 3v battery, which was 3.05v. The replacement showed 3.3v and I had no problems from that point until I bought my 2017. The lesson here is that the fob can get locked in the car despite good technology and intentions, so keep that in mind. It might also be a good lesson to change the fob battery once per year.

Only thing is sometimes if I get in the car after fueling, when I close the door it doesn't know I'm in it, so it gives me the 3-beep.

The C7 has better "vision" for the fob inside the car than the C6, and when I bought my first C7 I did some tests which showed that when the fob was anywhere inside it could see it. The C6 had no phone app option to unlock the car and I had a hidden key on that car, too. Saved my butt several times.
