As far as I remember the shutter operation on a Pentax ME is dependent on the battery working. (Like a lot of cameras of that era:- Minolta AG/XE, Olympus OM2 Nikon FE etc) If the camera is wound on and the shutter fired and sound suggests that the shutter has worked then the battery is not dead. If she was able to wind on after each operation then the shutter has fired although not opened It HAS to be something else. If the shutter is cocked then it is IMPOSSIBLE to wind on again unless the shutter is fired. This all points to a shutter fault such as the blinds not opening properly = sticky magnets.
With no film in the camera, remove the lens and open the back and point the camera at a light source. Fire the shutter and if the blinds are working you will see a flash of light as the shutter operates. If there is no 'flash of light' then the shutter is defective.
