Car ready to drive light will not come on and car will not start?

Yep, this is common when the 12-volt battery goes dead. I would remove it and have the auto parts store load test it for you and get you a new one if needed. Here is how in the diagrams below. Make sure all switches are off before you begin. This guide can help walk you through the repair safely:

Check out the images (below). Please let us know what happens.

It's a new battery 2 days old.

Good info, can I ask if the dash lights come on? Can you please upload a short video of what the car is doing? It can be a bad starter motor, also try to start the car when the car is in neutral as well. We should run a CAN scan to see if any codes are stored.

You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:
