Humor me, but did you try jump starting it?
It probably would make no difference but the reason I ask is because of a fluke I encountered a month or so ago. I was checking the front brakes on my 2015 Fusion. I had it on jack stands and wanted to spin the wheel so I could see the rotor turn. I had to tak it out of park which required turning the key to on. When I was done I started the car and remebered it wasn't in park so I shut it off, put it in park and attemped to start it again. Nothing! A couple clicks. Tried on/off a couple times and at one point saw something like "no key recognized." I thought I'd erased the key so I got the spare out, same thing. Ok I figured I disconnect the battery like you had and reconnect to see if that helped, it didn't (there's a longer version about how I dropped the 10mm bolt that connected the cable to the terminal, had to remove the splash shield to look for it and not find it and run to the hardware store for a replacement). Anyway, I had about given up and was ready to call a tow truck to take it to the shop when I thought, what the heck. I pulled the Mustang along side it, connected the cables, and it started right up. This battery is only 2 years old and I had no indication of a problem before that and it has had 0 issues or hard starts since. I don't know what I did but the jump seemed to remedy it after everything else failed.
