if you had the key close or in your pocket the cars CANbus is active. The click whine noise you hear in the right rear is the fuel pumps when you open the door.
A few checks would give you a good idea whats happening. Harbor freight throws a cheap meter in you shopping bag when you check out a few times a month. They are perfectly fine for checking DC voltage.
Everything else is guessing....
