Headlights will not turn off after locking care

Have a 2003 Chrysler 300 and the lights won't turn off after locking car.
It runs the battery down. Garage said they can not find anything wrong.
Has anyone else run into this problem and what did you do to fix it?
Below it did not give the ability to select 2003 just 2005.  But it is a 2003.
