Replaced the battery, why is there no power to the radio?

What is your question?

I had my dead battery replaced and now the auto locks, A/C, and Radio don't work? The keypad will sound the horn like I'm locking my doors but the locks don't move, they have to be manually put down or opened with key. The A/C blows hot air. And there is no power to the radio at all. How do we fix this??
