Radio& lights on dash panel stays on after turning car off and after key remove

sounds like a stuck door ajar/jamb switch..spray a generous amount of WD-40 in/on the door latches. open and close the doors several times to free up the stuck switch.. you can't see the switch because it's behind the door latch,inside the door panel.(part of the door latch) your car thinks a door is still open(probably the drivers door) after you close it.
