Question: my car won't turn over?

i have a 2003 Pontiac Grand Am V6 I tried to jump it and it worked but when i got it home it wouldn't crank over. My dash lights and headlights are bright, but my door lock, and trunk release won't work. When I jumped it it made a high pitch humming sound while driving home
