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.
