This isn’t actually a big secret, it’s actually a standard part of the service process. If you drop your vehicle off at a service centre, or even get a remote service where someone visits your home then they open the car without your key.
Imagine owning a Tesla and you go for a ride with a friend or family and say something nasty about Musk...how do I know I'm not risking my life with such dangerously surveilled vehicle!
