The basic connection process

A Logitech wireless keyboard connects to your computer in one of two ways: through a small USB receiver that plugs into your computer, or through Bluetooth if your keyboard and computer both support it. Most Logitech wireless keyboards use the USB receiver method, which is simpler and more reliable. The keyboard will not work until you complete the pairing process — just turning it on is not enough.

The steps differ slightly depending on whether your keyboard uses a receiver or Bluetooth, but both take about five minutes. You will need to have the keyboard powered on and your computer ready to recognize a new device. If you have lost the receiver or it is not working, you can still pair the keyboard through Bluetooth on most newer Logitech models.

Key Takeaways

  • USB receiver keyboards require you to plug the receiver into a USB port and press the connect button on the keyboard within 20 seconds for the devices to find each other.
  • Bluetooth keyboards need you to turn on Bluetooth on your computer, hold the Bluetooth button on the keyboard for three seconds, and select the keyboard from your computer's Bluetooth list.
  • If the keyboard does not respond after pairing, check that it is turned on, the batteries are not dead, and the receiver is plugged into a working USB port.
  • You can pair one Logitech receiver with up to six keyboards, but only one keyboard will work at a time unless you switch between them manually.

Connecting a USB receiver keyboard

Start by locating the small USB receiver that came with your keyboard. It is usually a thin rectangular piece about the size of a USB thumb drive. Plug it into any available USB port on your computer — the back of a desktop tower or the side of a laptop both work fine. Your computer will recognize the receiver automatically; you do not need to install software first, though Logitech software is optional and available on their website if you want to customize the keyboard.

Once the receiver is plugged in, turn on the keyboard using the power switch on the back or bottom. Within 20 seconds, press and hold the connect button on the keyboard — this is usually a small button on the underside or back, sometimes labeled with a wireless symbol. The keyboard and receiver will search for each other. You should see a light on the keyboard blink or turn solid, indicating the pairing is complete. Type a few characters to confirm the keyboard is working.

If nothing happens after 20 seconds, try again. Make sure the batteries in the keyboard are fresh — low batteries are the most common reason a keyboard will not pair. If the receiver is plugged into a USB hub rather than directly into your computer, try plugging it into a port on the computer itself, as some hubs do not provide enough power.

Connecting a Bluetooth keyboard

If your Logitech keyboard has a Bluetooth button instead of a receiver, or if you have lost the receiver, you can pair it through Bluetooth. First, turn on Bluetooth on your computer. On Windows, open Settings, go to Devices, and toggle Bluetooth on. On a Mac, open System Preferences, click Bluetooth, and make sure Bluetooth is on. Your computer will begin searching for nearby devices.

Turn on the keyboard and hold down the Bluetooth button — usually marked with a Bluetooth symbol — for about three seconds until you see a light blink on the keyboard. The keyboard will appear in your computer's list of available Bluetooth devices. Click on the keyboard name (usually something like "Logitech K380" or "Logitech MX Keys") to pair it. Your computer may ask you to confirm the pairing; if so, click yes or enter a code if prompted.

Once paired, the keyboard should connect automatically whenever it is turned on and within range of your computer. If the keyboard does not appear in the Bluetooth list, make sure it is turned on, hold the Bluetooth button again for a longer period, and check that your computer's Bluetooth is still on.

Troubleshooting when the keyboard will not connect

The most common reason a Logitech wireless keyboard does not work is dead or low batteries. Open the battery compartment on the back or bottom of the keyboard and replace the batteries with fresh ones. Most Logitech keyboards use AA or AAA batteries. After replacing them, try the pairing process again.

If you are using a USB receiver and the keyboard still does not respond, unplug the receiver, wait 10 seconds, and plug it back in. Then turn off the keyboard, wait a few seconds, turn it back on, and press the connect button again within 20 seconds. This resets the connection and often solves the problem.

For Bluetooth keyboards, if the keyboard appears in your Bluetooth list but does not type, try "forgetting" the device and pairing again. On Windows, go to Settings > Devices > Bluetooth, find the keyboard, click it, and select Remove. On a Mac, open System Preferences > Bluetooth, select the keyboard, and click the X button. Then repeat the pairing steps from the beginning.

If the receiver is plugged in but your computer does not recognize it, try a different USB port. Ports on the back of a desktop or directly on a laptop are more reliable than ports on a hub. If you have multiple USB devices plugged in, try unplugging others temporarily to see if there is a power conflict.

Using multiple keyboards with one receiver

Logitech USB receivers can pair with up to six keyboards at once, which is useful if you have multiple keyboards in different rooms or want to switch between a full-size keyboard and a portable one. To add a second keyboard to the same receiver, turn on the new keyboard and press its connect button within 20 seconds, just as you did with the first one. The receiver will add it to its list.

Only one keyboard will send input to your computer at a time. To switch between keyboards, simply turn off the one you are not using and turn on the one you want to use. The receiver will recognize the active keyboard automatically. If both keyboards are on, whichever one you type on first will take control, and the other will be ignored until you turn it off and back on.

Checking your keyboard model and finding the right manual

If you are unsure whether your keyboard uses a receiver or Bluetooth, look at the bottom or back of the keyboard. A receiver-based keyboard will have a small compartment or slot where the receiver stores magnetically, or instructions printed near the power switch. A Bluetooth keyboard will have a Bluetooth button and no receiver slot. You can also check the model number on the bottom of the keyboard and search for it on Logitech's website to find the specific manual.

Logitech's support website has downloadable manuals for every keyboard model. If you have lost your manual, go to Logitech.com, search for your keyboard model number, and download the PDF. The manual will show you exactly where the connect button is and which type of connection your keyboard uses.

Frequently Asked Questions

Can I use a Logitech keyboard receiver with a non-Logitech mouse?

No. Logitech receivers are designed to work only with Logitech wireless devices. If you want to use a non-Logitech mouse, you will need its own receiver or to pair it through Bluetooth separately. Some computers can handle multiple USB receivers at once without conflict.

What if I lost the USB receiver for my keyboard?

You have two options. If your keyboard supports Bluetooth, you can pair it through Bluetooth instead and never need the receiver. If it does not support Bluetooth, you can buy a replacement receiver from Logitech — search for your keyboard model number plus "receiver" on their website or a retailer. Replacement receivers are usually under $20.

Why does my keyboard work sometimes but not other times?

This usually means the batteries are dying. Replace them with fresh batteries and the problem should stop. If it continues, try moving the receiver closer to the keyboard, as distance or obstacles like metal filing cabinets can weaken the wireless signal. Unplug other wireless devices nearby, as they may cause interference.

Do I need to install Logitech software for the keyboard to work?

No. The keyboard will type and function with just the receiver plugged in or Bluetooth paired. Logitech software is optional and only needed if you want to customize keys, adjust settings, or use advanced features. The keyboard works fine without it.

Can I pair a Logitech keyboard with two computers at once?

With Bluetooth, yes — you can pair the keyboard with multiple computers and switch between them by turning the keyboard off and on. With a USB receiver, no — the receiver can only connect to one computer at a time. You would need to unplug it and move it to use the keyboard on a different computer.
