I’ve had a Logitech Bluetooth keyboard for a few years, it got stuck paired to a device and it basically bricked it. After doing some research, I found away of wiping the keyboard’s memory, allowing the keyboard to be used again:
Step 1:
Unpair, delete all Bluetooth settings regarding the keyboard in Windows or Mac.
Step 2:
Reset the keyboard by pressing the following keys: “Escape” – “o” – “Escape” – “o”,“Escape” – “b”
Step 3:
If the reset is accepted, you may see a light blink depending on your Bluetooth keyboard model.
Step 4:
Connect your keyboard to the computer via Bluetooth and your keyboard will be ready to go!
This works with Logitech multi-connect keyboards as well.
