But my point is that it should. Any digital lock should use good crypto, it doesn't matter if for ignition or doors. The fact that it's been proven that they did it badly even when they tried, aligns with my experience that their digital locks are not secure.

Whether my locks open with an easily-spoofable RF signal or with a bruteforceable key, the bottom line is still that they are not doing good crypto in situations where it's clearly necessary.
