Kindle 3 select button on the 5 way button does not work

Everything else on my kindle works except for the select button on the 5-way button.

I would like to either be able to fix this, or somehow substitute its function but I can’t find any solutions for this so far.

This mean I can’t choose a book to read, sync or change wifi, rendering my otherwise fully functioning device totally useless. Hate to throw away something for such a small flaw.
