Daughter tried to get the cd player working by loading in a few coins......

Anyone got any ideas on how to get them out or at least remove the radio and try to shake them out?
It's making noises like its trying to play something but then gives up aftera minute or 2 and the radio comes on.
Plus - After locking the car normally with the keyfob, the radio comes on itself if I haven't turned it off manually before getting out of the car.
So the car sits there locked and then the stereo starts blasting.
