Hum, I feel your pain. You said you already replaced the battery but I'd encourage you to go ahead and change it again, just in case. Use a different brand this time.
When it comes to the XTool I am not sure. Try to read and clear faults. I don't know how keyless entry works but it is recommended to have the car off before plugging the VAG tool, then turn the ignition on without having to start the car before using the tools. When you're done, make sure you turn the ignition off before unplugging the tool.
Also try reverting back the door auto lock function to what it was to see if it changes something.

Thanks for the advice on the scan tool. However, aren't there some times where the car needs to be running to perform some functions?
I'm impressed that you remember me turning off the auto lock. You are really following my car woes closely. I appreciate it man. I may try that if I get the error after the new battery. Thanks.
I am going to start a new post about my results of my scan tool results. They are a mess. Please look at them and let me know your thoughts.

I just can't catch a break with this car. I'm sorry to say but this car is the worst car I have ever owned. It is a beautiful car and rides nice but that's about it. Every few days there is another issue.
Today while driving I got a random, out of nowhere message on the dash saying "key not in the car" (something to that effect). It's the message where it shows a key and a question mark (?). I have push to start and that is how I started it this morning on the way to work and after about 30 min of driving I got that message. The key was in the cup holder by the armrest.
Then this evening when trying to start the car using the push to start a message would come up saying that it could not find the key or something like that. I had the key in my hand. I found that if I pressed the unlock button on the remote that it would then recognize it and start. I tried it several times and each time I would get the message and after I pressed the unlock button on the remote it would then allow me to start it using the push to start.
I drove the car somewhere and stopped like 4 times and it started perfectly those 4 times without displaying the message. So, it is very sporadic.
It is not the battery in the remote because I changed the battery about a month ago (a week or two after getting the car).
I wonder if this is something that I can fix using my newly acquired Xtool 401?
Any advice is appreciated. This car is wearing me out.
Thanks.

Tried your suggestion, but it didn't work the first time. I thought that I would try it again, so I just disconnected the positive and went to have a cup of coffee while I searched the web some more. With the battery still disconnected, I also checked the ECU connection to make sure no water had gotten in there somehow, but it was dry too. About 20 mins later, I returned and I reconnected the battery. I immediately started hearing some of the normal motor noises from the engine bay that I didn't hear on the first attempt, so I suspected that it might have done the trick. Sure enough, the car started right up. Dashboard lit up like a Christmas tree, flashing several warnings like TMPS, Cruise, Pre-Sense, Parking Assist, Start/Stop, etc. I figured the ECU had some re-learning to do, so I took the car for a short drive, parked, reset the TPMS in the MMI, and shut it down. Started it back up again, and all of the warning/error messages were gone.
Thank you again. Next step would have been to tow it to Audi service and throw money at them to fix it.
