Not all cars. Audi certainly doesn’t.

They certainly do. The 3-4 different Audis I have driven all have key cylinders in the door handles and a physical key in the keyfob. And you can start the engine when the keyfob is out of battery because they have a passive RFID built in the fob that the car can communicate with when the keyfob is inserted in the slot in the dashboard.
