Parked the car in the driveway, the battery had drained?

In the fuse panel on the left side of the dash there are two fuses that need to be checked, Module HEV and Module 1 both are 7.5 amps. The battery is charged by the low voltage converter which is inside the hybrid power control unit. If the fuses are okay, it sounds like you have a bad 12 battery. Here are the hybrid battery charging wiring diagrams so you can see how the system works and I have included a guide to help you test the fuses. Also, I found the instructions on how to change the battery out with the fuse locations as well.

I don't recommend a non-service professional to change this battery out but I want you to see what needs to be done to fix the car, so you know what you are in for with the repair. Check out the images (below). Please let us know what you find. We are interested to see what it is.

Module 1 shows up on the schematic. Module HEV. does not.

The car doesn't have a key. It has only a fob. I cannot turn on just the electrical circuit.

When you say the Module HEV fuse does not do you mean the fuse is not there? Is there a place where the fuse can be installed? Can you please upload an image? Also, we should do a CAN scan which is easy, you can get a CAN scanner (Controller Area Network) from Amazon for about $36.00.

Here is a video to show you how:

Image of the fuse box cover is added. Module HEV is not shown.

They would be the module fuse 7.5 amp. I see two of them in the diagram. With the system on do these fuses have power?
