A Logitech keyboard that suddenly stops typing is usually a connection, power, or software problem, not a dead keyboard. Most fixes take under five minutes and cost nothing. If you’re not sure the problem is specific to Logitech, start with our general guide on why your keyboard is not working.
This guide covers wireless models (K380, K400, MX Keys, MK270, MK345), Bluetooth models, and wired or gaming keyboards (G213, G413, G Pro). Work through the steps in order, starting with the simplest.
Why Is My Logitech Keyboard Not Working?
A Logitech keyboard stops responding for one of these reasons:
- Power: dead or poorly seated batteries, a drained rechargeable battery, or the power switch turned off.
- Receiver problems: the Logitech USB receiver (Unifying or Bolt) is unplugged, loose, blocked by interference, or in a faulty port.
- Pairing loss: the keyboard lost its link to the receiver or Bluetooth host, often after a Windows or macOS update.
- Bluetooth issues: the keyboard is paired to a different device or Easy-Switch channel.
- Driver or software conflicts: a corrupted HID keyboard driver or a conflict with Logi Options+ or Logitech G HUB.
- Settings: Fn Lock, Game Mode, Filter Keys, or Sticky Keys changing how keys behave.
- Hardware faults: liquid damage, a failed switch, or a dead circuit board.
If only some keys fail, the cause is more likely a setting, debris, or hardware. If the whole keyboard is dead, look at power and connection first. For brand-neutral steps that apply to any wireless model, see our wireless keyboard not working guide.
Try These Quick Fixes First
- Switch the keyboard off and on again using its power switch.
- Unplug the USB receiver, wait 10 seconds, and plug it back in.
- Move the receiver closer to the keyboard, ideally within 1 to 2 meters with a clear line of sight.
- Press any key and wait a few seconds, since many Logitech keyboards sleep to save power.
- Toggle Bluetooth off and on in your computer’s settings.
- Remove nearby interference such as external drives or USB 3.0 hubs placed next to the receiver.
If the keyboard still doesn’t respond, continue below.
Check the Battery and Power Switch
Weak power is the most common cause of a Logitech wireless keyboard not working. Symptoms include lag, repeated or missed letters, and intermittent cutouts.
- Check the power switch. It is usually on the top edge or underside. Slide it to On and look for a green LED.
- Replace the batteries. Depending on the model, Logitech keyboards use AA, AAA, or coin cell batteries. Use fresh, matching batteries from the same pack.
- Check battery orientation. One reversed battery breaks the circuit.
- Clean the contacts. Wipe the terminals with a dry cloth or a cotton swab lightly dampened with isopropyl alcohol.
- Charge rechargeable models. Keyboards like the MX Keys and MX Keys Mini charge over USB-C. A blinking red LED means low battery. Charge for at least 30 minutes and test again.
If the LED stays off after fresh batteries or a full charge, the keyboard may have a hardware fault. Jump ahead to testing it on another device.
Check the Logitech USB Receiver
Logitech wireless keyboards that don’t use Bluetooth rely on a small USB receiver, either a Unifying receiver (orange star logo) or a Logi Bolt receiver (Bolt logo). If it isn’t communicating properly, the keyboard appears dead even with good batteries.
- Confirm it is plugged in firmly. Loose receivers cause intermittent dropouts.
- Avoid hubs and front-panel ports. Plug the receiver directly into a rear motherboard port on a desktop or a main laptop port.
- Use a USB extension cable. It brings the receiver closer to the keyboard and away from interference.
- Check Windows detection. Open Device Manager and look under Human Interface Devices and Keyboards for the receiver. A yellow warning icon indicates a driver issue.
- Check you have the right receiver. Unifying and Logi Bolt receivers are not interchangeable. A Bolt keyboard needs a Bolt receiver.
Reconnect or Pair the Keyboard
A keyboard can lose its pairing after an update, a battery change, or a receiver swap. Re-pairing often fixes this immediately.
For Unifying receivers:
- Download and open the Logitech Unifying Software from Logitech’s support site.
- Click Advanced, then Pair new device.
- Turn the keyboard off, then on again, when prompted.
- Type to confirm the connection.
For Logi Bolt receivers:
- Open Logi Options+, choose Add device, and follow the pairing prompts.
- Switch the keyboard off and on as instructed.
For keyboards with a Connect button: press the Connect button on the receiver (if present) and on the keyboard, then wait for the LED to confirm.
If the keyboard refuses to pair, remove old pairings from the software, restart the computer, and try again. Some models need a full factory reset first. For example, here’s how to reset a Logitech K850 keyboard.
Check Bluetooth Connection
When your Logitech keyboard uses Bluetooth, the connection can drop or switch to the wrong device.
- Confirm Bluetooth is on in Windows (Settings, then Bluetooth & devices) or macOS (System Settings, then Bluetooth).
- Choose the right Easy-Switch channel. Press the Easy-Switch key (1, 2, or 3) for your computer. If the LED isn’t blinking, hold the key for about three seconds to start pairing.
- Remove and re-add the keyboard. Select the Logitech keyboard in your Bluetooth settings, choose Remove device, then pair it again from scratch.
- Check for interference. Wi-Fi routers, microwaves, and other Bluetooth devices can disrupt the signal.
- Re-enable the Bluetooth adapter. In Device Manager, right-click your Bluetooth adapter, disable it, wait a few seconds, and enable it again.
If the keyboard pairs but still types erratically, update your computer’s Bluetooth driver from the laptop or motherboard manufacturer’s website.
Try a Different USB Port
A faulty or underpowered port can stop both wired keyboards and wireless receivers from working.
- Plug the keyboard or receiver into a different USB port, ideally on the opposite side of the computer.
- Try both USB 2.0 and USB 3.0 ports. Some receivers work better on USB 2.0 because USB 3.0 ports can emit interference near 2.4 GHz.
- For wired Logitech keyboards, avoid unpowered hubs and plug directly into the computer.
- If the keyboard works in one port but not another, the second port may need a driver reset or may be failing.
Restart Your Computer
Restarting clears temporary driver glitches, stuck USB states, and background processes that interfere with input devices.
- Do a full restart, not just sleep or shutdown. On Windows, Fast Startup can keep a faulty USB state alive. Hold Shift while clicking Restart to force a full reload.
- On a Mac, restart and then reconnect the keyboard.
- After rebooting, leave the keyboard off or unplugged until the system loads, then reconnect it.
Update or Reinstall Drivers
Logitech keyboards use standard HID (Human Interface Device) drivers, so reinstalling them often fixes the problem.
On Windows:
- Press Windows + X and open Device Manager.
- Expand Keyboards.
- Right-click HID Keyboard Device (or your Logitech device) and choose Uninstall device.
- Restart your computer. Windows reinstalls the driver automatically.
- Check Universal Serial Bus controllers for any device with a warning icon, and update or reinstall it.
On Mac: there are no keyboard drivers to reinstall, but updating macOS and removing the keyboard from Bluetooth settings before re-pairing often helps. For more fixes, see our Mac keyboard not working guide.
Update Logitech software: install the latest Logi Options+ or Logitech G HUB (for gaming models). Outdated software can cause missing key mappings or a keyboard that stops responding after an OS update.
Check Logitech Keyboard Settings
Sometimes the keyboard works, but a setting makes it appear broken.
- Fn Lock: if F-keys do the wrong thing, press Fn + Esc (or the Fn Lock key on your model) to toggle function key behavior.
- Game Mode: on gaming keyboards, Game Mode disables the Windows key and some shortcuts. Turn it off in G HUB or with the Game Mode key. If the key is still dead, see our fix for the Windows key not working.
- Filter Keys and Sticky Keys: in Windows, go to Settings, then Accessibility, then Keyboard and turn off Filter Keys and Sticky Keys if keys feel delayed or unresponsive.
- Logi Options+ conflicts: if keys act strangely, quit Logi Options+ or G HUB, test the keyboard, then reinstall or update the software.
- macOS permissions: go to System Settings, then Privacy & Security and make sure Logi Options+ has Accessibility and Input Monitoring access.
- Keyboard layout: if typed characters don’t match the keys, check your language and layout in Windows or macOS keyboard settings.
Test the Keyboard on Another Device
Testing on a second computer tells you whether the problem is the keyboard or your system.
- Works on another device: the keyboard is fine. Focus on your computer’s USB ports, Bluetooth adapter, drivers, or settings. If you’re on a notebook, our laptop keyboard not working guide covers built-in keyboard issues that can interfere with external ones.
- Doesn’t work on another device: the keyboard, receiver, or battery is likely at fault. Try a different compatible receiver and fresh batteries.
- Test before the OS loads: press a key during startup and enter BIOS or UEFI. If the keyboard works there, the issue is software. If not, it is hardware or connectivity.
Logitech Keyboard Works but Mouse Doesn’t
If your Logitech keyboard types fine but the mouse is dead, or the reverse, the problem is usually shared hardware or pairing.
- Combo sets (MK270, MK345, MK540): both devices share one receiver. If one works and the other doesn’t, re-pair the dead device using Unifying or Logi Options+.
- Check the mouse separately: replace its battery and make sure its power switch is on.
- Separate receivers: if the keyboard and mouse use different receivers, check that each is plugged in and not blocked by a hub.
- Receiver overload: a weak signal can cause one device to drop. Move the receiver closer or use an extension cable.
- Windows power saving: in Device Manager, open each USB Root Hub, go to Power Management, and uncheck Allow the computer to turn off this device to save power.
If neither works, the receiver or USB port is the likely cause. If only one fails after re-pairing, that device may need replacement.
When to Replace or Repair It
Not every Logitech keyboard is worth repairing. Consider replacement if:
- The keyboard stays dead on multiple computers with fresh batteries or a full charge.
- Liquid damage caused sticky keys, corrosion, or an unresponsive board.
- The receiver is lost and the model uses a proprietary one. Logitech sells replacement Unifying and Bolt receivers, but compatibility matters.
- Keys have physical wear, a rechargeable battery no longer holds a charge, or the keyboard is out of warranty.
Check warranty first. Logitech offers a limited hardware warranty on most keyboards, typically one to three years depending on the product and region. Contact Logitech Support with your serial number before paying for a replacement.
For budget models like the K270 or MK270, replacing the keyboard is usually cheaper than repairing it. See our breakdown of keyboard replacement cost in 2026 to compare.
