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!
Made my keys much less bulky
I don’t have a 3D printer currently. I did help my cousin’s kid by one and they told me if I ever wanted to print something to let them know, but I have a feeling I’ll need to design my own with some trial and error.
I’ve hesitated buying one, because the idea of having a machine to melt plastic in my house seems like a bad idea when it comes to air quality.
If it’s something you worry about, the enclosed models frequently either come with, or can be fitted with a carbon filter, and if you are really worried, you can use dryer vent to get it outside.
With the most popular plastic (PLA) at printing temperatures, there isn’t any data showing toxic byproducts. When you get into things like ABS and resin you have to think more about fumes.
Look at Mr. Moneybags here with his car that has the AC add on and still functional!
> None of these components is particularly extraordinary in isolation
That said, I didn't perceive a problem either, and my self-diagnosis is that "none of the X" feels like it could be evoking a singular item that failed to be found.
Cambridge says...
> In formal styles, we use none of with a singular verb when it is the subject. However, in informal speaking, people often use plural verbs...
Collins says:
> Since none has the meanings “not one” and “not any,” some insist that it always be treated as a singular and be followed by a singular verb: The rescue party searched for survivors, but none was found. However, none has been used with both singular and plural verbs since the 9th century. When the sense is “not any persons or things” (as in the example above), the plural is more common: … none were found. Only when none is clearly intended to mean “not one” or “not any” is it followed by a singular verb: Of all my articles, none has received more acclaim than my latest one.
But it was "none of -these- X" which (to me, at least) is a secondary signal for plurality indicating that "are" is (doubly) preferable to "is".
(I don't find "none of these components is ..." to be egregiously wrong but it definitely gives a brain hiccup where the "... are ..." variant is much smoother.)
The mechanical key fallback pattern is standard across the industry for sure.
Article says key fobs are the same across all their cars and this looks the same as mine for a Sealion 5, there is no hinge for the key you just pull it out.
Likely the article authors just assumed from looking at the scan, if they’d actually tried to remove the key they would have realised their mistake.
Nowadays the physical key is only a backup, safely stowed inside the fob. It is meant to be pulled out only in an emergency.
When keyless start came, there was a dummy button that fit in the ignition lock that could be pushed to start. If there was a problem, you could pop it out and use the key as before.
IIRC, all that, so may have mistakes. Just crossed my mind that they went a few decades between no metal ignition key and keyless. MB being MB, I wouldn't be surprised if they still had models with that same "old" system and keyless as an option.
All this to say Hyundai certainly knows how to do this. If they didn’t do it, it is almost certainly a deliberate omission.
