Passanger side unscrew the bolt from the bracket that is holding the battery down. Disconnect the terminals and replace the battery. For the radio code what you can do is take the radio out to get the serial number. It's going to be a long number on the side of it. Go on http://www.radio-code.lt/ and search the data base. I was able to get mine with out a problem. Good luck.
