It is the deadlock feature. It is great for locking people in. You can leave the window down and still no one can reach in and open the door.
If you have someone inside then press the lock button a second time and you will be able to unlock from inside.
I believe you can change the behaviour via dash settings on some new models, or via VCDS.
I assume you have not played much with the keys, have you tried holding the unlock button for 5 seconds ?
That is a real trip the first time.
