Changed battery: car doesn't recognize key fobs S80 2008

Yesterday (Thursday), the car ran fine. Overnight, the battery went down, tested at 6 volts. I charged it up, and the auto parts store confirmed that the battery's fine. I reinstalled, and now:

a) the emergency lights are flashing, which the dealer says is the alarm system going off without the horn beeping (thank goodness for not beeping!), and
b) the car doesn't recognize either of the key fobs, offering the message, "key not found."

I've got a Monday appointment for the dealer to look at it, but does this sound like something I can correct myself? Can I convince the car to recognize the key fobs that it knew just yesterday?
