Not fully true. Just as it's not true with non-car keys. Some blanks are heavily protected. Now these days with the dissemination of cheap cnc mills, maybe thats a bit more trivial, but you are paying a lot more for a cnc mill than you pay for a old key grinder.

Same issue we have now with ghost guns honestly. CNC mills are powerful tools, with the right software you can essentially just place the properly sized chunk of metal in the box and hit go.

That's why I said traditional key. They're just metal with a few parts cut to a specific profile. It's once you start mucking around with immobilizers and other encrypted things that need the factory tools... Those can cost tens of thousands, and usually require continuous internet access back to the home office.
