Back up the page I said the OP should disconnect the siren. If that thing isn't working I still believe he should do that. He also said every thing else is working, but he needs to check the map lights in the interior and the hatch/truck light. If those aren't working fuse 9 is blown and that is why he can't unlock/lock his car.
I just read OP post #26; no interior lights. HE NEEDS TO DISCONNECT THE SIREN AND CHECK FUSE 9 UNDER THE HOOD.
