This was stated about the key: "Folded into the base is a mechanical backup key, a flat metal blade in a hinged housing."

I own a BYD: this is not true. The key is not hinged; rather, the entire mechanical key pulls out when a small clip is unlatched near the top of the assembly (you can see it in the CT). I assume the circular hinge-looking mechanism in the CT is just a by product of the plastic/metal weld process.

Nonetheless: very cool tech demo!

I wasn’t surprised by the backup key, but rather by how empty it was. I really wish key fobs were smaller. They are quite bulky in a pocket and bigger than all my actual keys combined.

It was suspected in the past that Lumafield used AI to write the descriptions of previous scans. It is possible they are still doing so.

The mechanical key has a hinge (to be able to operate it), but it’s not “hinged” to the fob.

Having a mechanical key hidden in the electronic key fob is nothing new, it’s common on many cars.
