Console cup holder & power lock button installation
 

I have a 2002 A6. I have two questions that I was hoping someone could help me with

1. My cup holder on the console has been broken forever. I finally found a replacement online but I can't figure out how to remove the old one. The new one looks like it is in a housing. Can anyone help me figure out how to remove the old one and install the new one.

2. Drivers side door lock button - The finish is all worn off of the buttons. I ordered a new one. How do I remove the button?

Thank you,

Len
