Logitech G11 phantom Asterisk input with key press

[Straypuft]

A few months ago, my G11 keyboard started to act up by inputting an asterisk when I press 'a', so both of those would show up on whatever I was typing, like this: *a

I have since bought a new keyboard, but was wondering if there is anyway for a guy with little experience in fixing stuff like that to salvage it.

Keyboard was out of warranty at the time.
