Deck Problem

My buddy has an Eclipse deck in his Blazer with a security feature on it that when power is shut off, it disables itself (only temporarily of course) and his battery recently died. He tried and soundworks store but they were of little help (kind of sad). So I guess what I need to know is what steps do you take so that it can be played agian and not electronically "locked"?

put in the radio code. If he can't remember it I think you have to send it to the manufactuer
