Default Noobie needing some help with error codes

I picked up a 2009 S5 4.2L and I have couple kinks I would like to iron out. I about an OBDeleven and I am getting these error codes. My passenger door does not unlock unless I open it. Sometimes my door assist work and sometimes it does not. I noticed if I clear all the error codes it generally works until it gives errors again. I have bought the sensor for the passenger door because it said it was bad, just need to replace it. The radio and back up camera both work but I am getting an error code. The lane change assist I have not seen work at all. Finally one of my keys does not unlock the doors or anything but I noticed if it is in the car, the car will start. Any help and direction is appreciated, I have been lurking and researching but these codes I am having troubles with solving.

As I mentioned in the A5 group on facebook, this has equally been covered in depth in past threads. I personally posted a bunch of links and info regarding door handle sensors, and door actuators.
The early years A4/A5 used a door handle sensor that has an orage-ish transparent plastic layer to it that eventually gets compromised by water over time. The revised door handle sensors are completely enclosed to correct this. They can be acquired off of ebay or AliExpress for dirt cheap. Something like over $100 each from dealership and about $15 to $20 each from Ebay or Aliexpress.
I've been using the ebay door handle sensors for over 2 years without issues. I also acquired a driver's door lock actuator from AliExpress for less ten $50.

This has everything you need for the door handle sensors.

Also refer to the Files Tab of the A/S/RS5 facebook group as I created an ample amount of data for the door handle sensors and door actuators.
