I parked it in the garage and locked it. I came back about 6 hours later and notice it's making a light beeping noise and my blinkers are flashing with it.
I tried two different keyfobs, nothing would work to unlock.
I opened it manually and my car will not turn on at all.
Security light is flashing and my blinker lights were flashing. I turned off my blinkers from auto and the lights will stop, but it will still beep.

What's the next step?!?!

EDIT: Unlocking all doors manually and opening caused the beeping and flashing to stop. My car ignition is now stuck in "Green", but won't start or make a noise.

Sounds like the immobiliser has been triggered.

Open the bonnet and disconnect the battery.

leave it off for about 10 mins and then re-connect.

Give the whole system a quick reboot.

Dang. I wonder if someone tried to steal it.

Eh, don't think so. It was in a 3 car garage in Irvine. Car was farthest from opening and a person would of had to pass an unlocked 2015 BMW X5 and unlocked 1966 Mustang to get to my car. Nothing looks out of the ordinary and there was money laying on the dash of the X5.

Agreed on trying to disconnect the battery for 15 minutes to see if that resets everything.

Update:
I hooked back up the battery and I was getting no power at all. I thought maybe it was the battery even though it was from 12/16. I brought it back to Costco and I was told that I was given the wrong battery for my car. The previous battery was not strong enough and it was the reason for the premature failure. Purchased new battery and everything worked great on first try.

Sounds about right, a battery with lower CCA's will struggle eventually when powering all the electronics needed.

A premature failure would be one of the effects.
