The red button is to reset it out of neutral and back into park. Here are a few photos to show you what mine looks like as well as position of the Allen key when I unlock. If you try to turn starting from closer to the driver then there isn't enough space to turn enough degrees to put it into neutral.
Pictures might be out of order since I'm posting from my phone.

Edit*: I see the order of my pictures now.
First picture is the car in neutral.
Second picture is starting position of allen key.
Last picture is what the area looks like without the cap, and my spring that flew out (cap is MIA).
