so i took my stock deck out of my 2000 silverado 1500 and put it directly back in. when i went to start the truck after word, it wouldnt start as if the battery was dead. tried jumping it and nothing. tried disconecting the battery, still nothing. i think its the security but not to familier with all that. . . does anyone have an ideas of what could be the problem or a way i can fix this without going to the dealer or forkin out a bunch of cash??
