Cadillac XTS battery dead with key fob inside

2013 Cadillac XTS, all 3 key fobs are in the center
console, because we brought it to a mechanic for
unrelated reasons. Battery died when I shut it off.
And I can’t get into it because the doors locked
when the battery died, and I can’t get to the battery
because the hood is opened by a button inside the
car, which I can’t get to because the keys are
inside.
