This guide fits for a Logitech G810 and maybe also some more keyboards like the G610
After using my Logitech G810 gaming keyboard for four years, some problems occurred with the shift key on the left side. By the way, I’m using a German layout. For me, it’s not surprising that this is one of the first keys which starts making problems, because beside the W-A-S-D keys and some others it’s the most frequently used.
