>those things rolling around in your keyboard are key weights that have broken off of
some of the keys. the keys that they have broken off of need to be replaced. contact a
service center for parts. Although parts are tough to get. You could just remove the
weights and play the keyboard with a couple of broken weights. Also all the others will
eventually break.....

Kurzweil service will most likely be VERY expensive.
The hardware you've described sounds like key counterweight hardware.
If nothing is actually broken but just fallen off , the hardware can
just go back whence it came.
I've used gorilla glue on a General music keyboard with great success
if something plastic is broken.

If you're not technical, take it to someone at a music instrument
repair place and have them redo the hardware and ALSO make sure the
rest ( that are similar) are also tight. While it's open have the
memory battery replaced.
