It wouldn't (and in my limited experience 3D printed plastic parts are

They are, but 3D-printed keys could easily operate such a lock. There is no elaborate
mechanics that is driven by the turning of this particular key. I've printed many
keys, even used them even as bump keys with no problem.

You can also print in metal. I've had keys made for about $8 each (the dimple ones as
shown in the first video).
There's software that can easily create a model of a blank key, given a picture of the
keyway.
Then there's impressioning, a technique very suitable to create a working key from a
key blank. Of course, you can also disassemble the lock and measure pin lengths. To get
the correct lengths, there's databases. Using a dremel is not the easiest way to do
this.
