Normally you can find it on the left trunk support arm (does that make sense?) Put in the hardwired code, then push 1, then put in a 5 button code of your choice. Do unlock or relock things, you put in your 5 digit code, then push the first button for the drivers door, second button for passenger door, third for the trunk, and four and five together to lock the doors.
(that should be correct info, it's been a while since I last saw my car :-( )
