If the anti-theft is preventing the engine from starting, the lights would still turn on. Therefore, I suspect we lost power at some point.
Do me a favor. Let's start by testing a couple of fuses. In the underhood fuse box, there are two to check. See pic 1. In addition to checking the fuse, confirm there is power to it. Here is a link you may find helpful:
Next, I want you to locate the inertia switch. It is located in the trunk, left side. It shuts power to the fuel pump if there is an accident. Check and reset it and see if that changes what you are experiencing.
Do this and let me know what you find.
