I come home at 2:30 today. Two hours later, I go out to the garage to find my car clicking repeatedly while the parking lights flicker in unison with the clicks. I hadn't even gotten into my car yet. It was doing this all by itself. The sound appears to be coming from a fuse box beneath the hood. I have keyless entry and cannot start my car.

I will note that my oil light came on last week and also, at around the same time, the battery light for my fob. This seems battery-related, but I can't imagine either of those would make my car come alive on its own like this. A couple times in the past, I have pressed the ignition button to have it turn over and grind a few times before it actually started (akin to turning the key and having to hold it for a few seconds before the car starts).
