alt Hacker NewsI guess my intent was not to point out that it has a mechanical key, rather that the description of the key on the webpage was wrong (it is not hinged).
The mechanical key fallback pattern is standard across the industry for sure.

Ah, I misread your earlier revision's enthusiasm at the end as being about the mechanical key, not the CT scan.

Before keyless became defacto standard, most keys were fixed on a hinge - you'd first unlock your car by pressing a button on the fob, then swing the key open and use it to start the car.
Nowadays the physical key is only a backup, safely stowed inside the fob. It is meant to be pulled out only in an emergency.

It's entirely possible that the BYD key they scanned and the BYD key you possess are of different designs.
