The Logitech K810 has been my favorite keyboard for many years. I have one at home and one in the office. It allows to easily switch between 3 different devices. It has the same size and layout as most notebooks, is stylish, and a blast to type.
But one day about a year ago something strange happened. When I wanted to type a ‘\’ I got nothing. When I wanted to type a ‘<‘, I would get a ‘Â§’. When I wanted to type a ‘>’, I would get a ‘Â°’. And vice versa. So, effectively two keys were swapped. This was only on the Windows workstation in the office. When I switched the keyboard to the Linux notebook or to the phone, all keys were correct. It also never happened at home.
At first I thought this was a joke by my co-workers. So I tried everything on the windows machine: un-pairing and re-pairing. Scanning the registry for uncommon key mappings. Nothing helped until I found a page that described how to perform a factory reset on the keyboard. The problem was solved, but only for a year. Last week when I came to work after the weekend, the very same keys were swapped again. Finding the page with the reset instructions was more difficult than I remembered. It was not freely available, but only after logging in on the Logitech support page. That is why I want to preserve it here, in case it happens again to me or anybody else:
- un-pair and remove the keyboard from the bluetooth settings on your pc
- reset your keyboard: with keyboard on and unpaired from any device, press the following key sequence:
- â€œEscapeâ€, â€œoâ€,â€œEscapeâ€, â€œoâ€,â€œEscapeâ€, â€œbâ€
- if the reset is accepted the lights on top of your K810 will blink for a second
- reconnect your K810 to your pc and test it on other devices if possible.
