There's a theorem of computer science that roughly says
every program can't handle some conditions. In this case the
car's main central processor(s) said there was no fault but the car
would not start. After the maker offered to investigate for a 4-figure
sum plus expenses the owner decided to break into the car's electronics
and fix it themselves. Turned out another compter on that car's local
network did know what was wrong and we tinkerer around until we found
the problem. A shorted switch in the centre console.

Actually it was "old mil grade encryption". Anything with less than a 512bit
key these days is "old". Again, the footnote in the original post
gives a hint of the details.
We looked around and found a list of relevant keys on the web and one
of them worked for that maker in the relevant subsystem.
It took a couple days in all but saved a few thousand. The bad switch
was a $1 item.
It took another day to replace. Has anyone tried to remove a centre
console lately? Apparently you need a phd in engineering to do it.
Or you must be willing to live with the axe marks.
