I saw the news that Hyundai/Kia company remove standard key system.

The original new article dated 4th of March 2019 : http://www.hankyungnews.com/news/18177

It states that Hyundai Motor company developed digital key which works by smart phone application. They are applying this digital key system to all new cars instead of standard smart key system.

The below are the example of smart key system which Hyundai Motor Group blog published.

Do you think it will affect smart key business of Hyundai/Kia Car?
Wondering if the other car companies(Ford, BMW, etc) change the key system too.
