It's locked out because power was removed so it thinks a thief took the radio out of the car. There's nothing you can do but punch in the code. Look in the owners manual pouch, sometimes there's a card with the code in there.
If not, you can call the dealer with the vin to get the code. Some dealers won't do it over the phone thinking maybe you stoled the radio.(you know, society) If so you'll just have to stop by the dealer with the car. Either way there should be no charge and it shouldn't take but 10 minute's for them to look it up.
Hope this helps.
