Are you talking about press to unlock fobs, or proximity keys?
I was under the assumption that we are talking about proximity keys. Old ignition keys use RFID, but a broken encryption system. They are still secure because the range is a few inches. Newer cars with unlock from the pocket / push to start, use challenge based auth and strong encryption.
Click to unlock fobs use secure PRNGs. That is a separate discussion, and they are generally secure. Maybe this is what the reporter was talking about, but I assumed these cars had proximity keys. Even if this is what the reporter was talking about, they were not way off base, as this still falls in the "should be impossible" category.
