E53 4.4 won't turn over

So, of course, I come to work this morning and give it another shot. Using the same key as last night, I remotely unlock the doors and there is a distinctly different sound indicating it's unlocked. I believe there are 2 chirps when normally unlocking it and in this case it was more like 4. As soon as I hear this, I think to myself, it's going to start now. And sure enough, it fires right up.

So I'm pretty convinced it's related to the alarm system but can't figure out why I couldn't get it to start last night. I'd love to know what I could have done different to correct it. Does sitting for a period of time allow the alarm to reset itself?
