It’s probably just personal preference and the door lock issue is probably a security precaution. One of the big ways people are breaking into or stealing modern cars that use “smart” keys is with a mirroring attack. They use a long-ish antenna (1m or so) to pickup the FOB inside your house, then mirror the signal to the car with a phone/tablet. Once they’re in your car, things get even worse. Honda’s for example used to store their security codes in the OBD computer (I don’t know if this is still true). Meaning thieves could plug in a technician OBD tool (they’re like $1,000 on Amazon), then program a brand-new virgin key for your car, right there in your driveway, hit the start button and drive off. All in under 30-seconds. The non-smart keyed cars were even worse, since the alarm doesn’t go off if you pick the lock (no joke lol)
To add to this, Kia (and Hyundai) were previously vulnerable to the USB cable hack - people could tear down the steering column and use a charger cable to start the car and drive away.
