    I bought a used 2002 chevy blazer 1 year ago. I want to change the battery but if I disconnect the cables my radio will be locked out. a previous owner set the code and I don't have a clue what it is. can somebody help me to get the code so I can disarm the anti theft feature while I change the battery? thanks in advance for all your help.
