I hate to burst your bubble but there's almost no physically keyed lock systems that are meaningfully secure and of the lock types that are difficult, none of them are featured in cars as far as I'm aware and employing those types of lock in cars is probably more expensive than what's currently being done. See Lockpicking Lawyer popping many car lock types in these videos. If he wasn't trying to show and tell on a video, most of these car locks would just take a few seconds in skilled hands. https://www.youtube.com/watch?v=eVZ67dcY9_g https://www.youtube.com/watch?v=eVZ67dcY9_g https://www.youtube.com/watch?v=F8fbxN3Z5e8 https://www.youtube.com/watch?v=F8fbxN3Z5e8 https://www.youtube.com/watch?v=c1MMT08A9kY https://www.youtube.com/watch?v=c1MMT08A9kY https://www.youtube.com/watch?v=FRZ2YXlZV-o https://www.youtube.com/watch?v=FRZ2YXlZV-o https://www.youtube.com/watch?v=ZtkNQSk9xRU https://www.youtube.com/watch?v=ZtkNQSk9xRU Physical keys combined with [actually] secure electronic or radio combinations are still your best bet, though Kia and Hyundai felt like they could save a buck by not doing that. But even still, if the user can trivially or quickly unlock something, there's a good chance the design constraints will force a compromise that weakens security.
