The basic connection process depends on your keyboard model and computer type

Most Logitech wireless keyboards connect in one of two ways: through a small USB receiver (called a dongle) that plugs into your computer, or through Bluetooth if your keyboard and computer both support it. The USB receiver method is more common and usually works immediately after you plug it in. Bluetooth connection requires you to put the keyboard into pairing mode and then select it from your computer's Bluetooth settings.

Before you start, check which type of keyboard you have. Look at the box or manual, or search for your model number on Logitech's website. The model number is usually on the back or bottom of the keyboard. Knowing whether you have a USB receiver keyboard or a Bluetooth keyboard will tell you exactly which steps to follow.

Key Takeaways

  • USB receiver keyboards need the small dongle plugged into a USB port; most work immediately without any software installation.
  • Bluetooth keyboards require you to hold the power button or a pairing button until a light blinks, then select the keyboard from your computer's Bluetooth menu.
  • If your keyboard does not respond after connection, check that batteries are installed and the power switch is on.
  • Logitech's Unifying receiver can connect up to six wireless devices at once, so you may be able to use one receiver for both keyboard and mouse.

Connecting a USB receiver keyboard

If your keyboard came with a small USB dongle, this is the simplest connection method. Locate an available USB port on your computer — any USB-A port works, whether it is on the front, back, or side of your machine. Plug the dongle fully into the port until it sits flush.

Your computer should recognize the keyboard within a few seconds. You may see a notification on screen, or the keyboard may simply start working without any visible confirmation. Type a few characters to test. If nothing happens, check that the keyboard has batteries installed (usually two AA or AAA batteries in a compartment on the back) and that the power switch on the bottom is turned on.

You do not need to install any software for basic typing. However, if you want to customize buttons or adjust settings like key repeat speed, you can download Logitech Options or Logi Options+ from Logitech's support website. This software is optional — the keyboard will work without it.

Connecting a Bluetooth keyboard

Bluetooth keyboards require a pairing step before they work. First, make sure your computer's Bluetooth is turned on. On Windows, open Settings, go to Bluetooth & devices, and toggle Bluetooth to on. On Mac, open System Settings, click Bluetooth, and make sure it is enabled.

Next, put your keyboard into pairing mode. Most Logitech Bluetooth keyboards have a power switch on the bottom and a separate pairing button (sometimes labeled with a Bluetooth symbol). Turn the keyboard on, then hold the pairing button for three to five seconds until you see a light blink on the keyboard — usually a blue or white LED. The blinking light means the keyboard is ready to pair.

On your computer, look for the keyboard's name in the Bluetooth device list. It usually appears as "Logitech K" followed by numbers or letters. Click on it to pair. Your computer may ask you to confirm a code or simply connect automatically. Once paired, the light on the keyboard will stop blinking and stay solid, meaning the connection is active.

What to do if the keyboard does not respond

If you have plugged in the USB receiver or paired via Bluetooth but the keyboard still does not work, start with the basics. Open the battery compartment on the back of the keyboard and check that batteries are present and installed correctly — the positive and negative ends should match the diagram inside the compartment. If the batteries look old or corroded, replace them with fresh ones.

Check the power switch on the bottom of the keyboard. It should be in the on position. If it is already on, try switching it off and back on again. Wait a few seconds after turning it back on before typing.

For USB receiver keyboards, try unplugging the dongle and plugging it into a different USB port. Sometimes a port is not working properly, or moving the dongle to a port closer to where you sit improves the signal. For Bluetooth keyboards, forget the device from your computer's Bluetooth settings and repeat the pairing process from the beginning.

Using Logitech's Unifying receiver with multiple devices

If you have a Logitech mouse and keyboard that both use USB receivers, you may be able to use a single Unifying receiver for both devices instead of two separate dongles. The Unifying receiver is a small USB dongle that can connect up to six Logitech wireless devices at once.

Check whether your keyboard and mouse are Unifying-compatible by looking for the Unifying logo on the device or its packaging. If both devices support it, you can download Logitech's Unifying software from their website. The software walks you through pairing each device to the single receiver. This reduces the number of USB ports you need and can make your desk cleaner.

Connecting to a Mac versus Windows

The connection process is nearly identical on Mac and Windows for USB receiver keyboards — just plug in the dongle and it works. For Bluetooth keyboards, the steps are slightly different because the settings menus are in different places, but the concept is the same: turn on Bluetooth in System Settings on Mac or Settings on Windows, put the keyboard into pairing mode, and select it from the device list.

One difference: some older Logitech keyboards may require Logitech Options software to work fully on Mac, while Windows users can often use the keyboard without any software at all. Check Logitech's support page for your specific model to see if Mac drivers are needed.

Frequently Asked Questions

Can I use a Logitech wireless keyboard with a tablet or phone?

Bluetooth Logitech keyboards can pair with tablets and phones that support Bluetooth, including iPads and Android devices. USB receiver keyboards cannot work with tablets or phones because they do not have USB ports. Check your device's Bluetooth settings and follow the same pairing steps as you would for a computer.

What if I lost the USB receiver for my keyboard?

You can purchase a replacement Unifying receiver from Logitech or a retailer that sells computer accessories. The receiver is inexpensive and works with any Logitech Unifying-compatible keyboard. You can also contact Logitech support with your keyboard's model number to find the correct replacement receiver.

Why does my keyboard keep disconnecting?

Wireless keyboards disconnect when batteries are low, so replace them first. For USB receivers, try moving the dongle closer to the keyboard or away from other wireless devices like routers or microwaves, which can interfere with the signal. For Bluetooth, make sure your computer's Bluetooth is still on and the keyboard is within range (usually 30 feet or less).

Do I need to install software to use my Logitech keyboard?

No. Both USB receiver and Bluetooth keyboards work for basic typing without any software. Logitech Options software is optional and only needed if you want to customize buttons, adjust repeat speed, or use advanced features. The keyboard will function normally without it.
