Default Theft Deterrent C7 system disarm, real solution???

I know, frequent thread, but NO solutions.
History: Installed new battery, no problem immediate start and drive home.
Contracted Disease: Tried to start car a week later (battery was on Vette charger)
dash came on for short time theft deterrent notice, all went dark. Had to use lever
to open door. Car would not start

Attempted cure: disconnected battery, and reconnected after short time
Car door will not open. Dark dash
have done all the tricks...for immobilizer reset (panic button, then lock/unlock sequence.
Car is locked, windows locked unable to get inside. Have to do the trunk key
to open, Will disconnect battery.
What is the key/ start button, sequence????
Does any know how to avoid flat-towing a Z06 to the dealer
and tearing off splitters and everything else, let alone having to
go to harbor freight to get wheel dollies because:
It's an Automatic stuck in Park!

I love my Porsches
My BMW's
My Audis
Much more than my Z06...now

HELP

Sounds to me like a dead/dying battery; not all batteries are good from the factory. Or loose connections.

Our cars are such battery hogs, that even a marginal battery can cause all kinds of issues.

If it was me, first I would check to make sure all connections are tight, and if so, I would pull the battery out and take it in. Whether it load tests OK (I've had sub-par Vette batteries test out "OK," but in fact weren't powerful enough), I would replace it and see what happens. Certainly, easier than a tow.

Have you tried your other fob or replacing the battery in your fob?

thank you. As stated
new battery fully charged
connections solid
2 key fobs
Theft deterrent unable to defeat
and no one has remedy except tow to dealer
breaking splitter of Z06 in process
fortunately in garage and not
in less convenient place
(Good movie plot:
One lap of America
Stuck on race track 3,000 mi from home)
ugh!)
