Why My Logitech Keyboard isn’t Working? (Mouse Works Fine)

This problem is frequently reported, especially by Logitech MK850 wireless keyboard and mouse combo users.

Low batteries are among the most common reasons for this issue. So, the first thing to do is to replace the keyboard batteries.

The Logitech unifying receiver should be directly connected to the computer, not the USB hub.

If your keyboard supports pairing with multiple devices, double-check that you have selected the correct device on the keyboard.

Some Logitech keyboards have a physical power switch, so verify that the switch is in the ON position.

If it’s still not working, follow these troubleshooting steps:

1. Unplug the Unifying receiver
2. Check Bluetooth
3. Restart your PC
4. Install Logitech Options
5. Reset your Logitech keyboard

You don’t have to try all of them; follow them in order until your keyboard starts working!

Remove and Re-insert Unifying Receiver

Most Logitech keyboard and mouse combos offer both Bluetooth and unifying receiver connectivity options.

The unifying receiver connects the keyboard and mouse to your computer using a single device.

If the problem is due to a connection issue, follow these steps:

1. Unplug the unifying receiver from your computer.
2. Turn off the keyboard and mouse and wait 3 minutes.
3. Afer 3 minutes, turn on your keyboard and mouse.
4. Next, plug the unifying receiver back in.

Connect the receiver to a different port if your computer has multiple USB ports.

Check Bluetooth

If you have connected your Logitech keyboard through Bluetooth with your PC, confirm that Bluetooth is not turned off on your PC. Here’s how to do that:

1. Open Windows Settings.
2. Under Bluetooth & devices section, you will see toggle switch for Bluetooth.
3. Make sure it is set to On. See the screenshot below:

Windows 11 has an Airplane mode that turns off Bluetooth and Wi-Fi when activated. Make sure that this mode is turned off.

Restart your PC

Sometimes a software error or glitch in a PC causes many random problems such as external keyboard issues. These issues can be easily fixed by simply restarting your computer.

Remember to disconnect the unifying receiver from your PC before restarting it, and then plug it back in once your computer reboots.

If this does not work, move on to the next solution.

Install Logitech Options

Logitech Options is an amazing software that updates your Logitech wireless keyboard drivers and allow you customize its buttons.

However, it does not support all keyboards. Here’s list of all the Logitech Options supported keyboards:

So, if Logitech Options supports your keyboard and you haven’t installed it already, install it and see if it fixes your keyboard problem. Here’s how to do that:

1. Download Logitech Options.
2. After installation, launch it.
3. Disconnect and then reconnect your wireless keyboard to your computer.

If the keyboard is still not functioning, you may need to reset it.

If the previous solutions didn’t work, reset your Logitech wireless keyboard. This method is known to fix various keyboard issues, such as unresponsive keys, connectivity problems, or input lag.

Note that resetting the keyboard will erase all your customized settings and revert it to its default settings.

Here’s how to reset your Logitech wireless keyboard:

1. Turn off your keyboard by using its power button.
2. Remove the batteries from the keyboard.
3. After removing the batteries, hold the power button again for 10 to 15 seconds to drain residual power.

That is it. You have successfully reset your keyboard.

Now, connect it back to your computer and see if it works. If it’s still not working, your keyboard may have hardware issues.
