To pair your Logitech K520 keyboard, you must use the included Logitech Unifying USB receiver and Logitech software, as this keyboard does not support Bluetooth. The process involves plugging in the receiver, installing the software, and using it to pair the keyboard with your computer.
What you need to pair your Logitech K520 keyboard
The Logitech K520 keyboard connects wirelessly using a Logitech Unifying receiver, not Bluetooth. You will need the keyboard itself, the small Unifying USB dongle, and Logitech's pairing software installed on your computer. A single Unifying receiver can connect up to six compatible Logitech wireless devices, including the K520 keyboard and its accompanying mouse if you have the MK520 combo.
Step 1: Plug in the Logitech Unifying receiver
The Unifying receiver is a small USB dongle that plugs into an available USB-A port on your computer. Insert it directly into a port on your desktop or laptop. Do not use a USB hub if possible, as a direct connection ensures the most reliable communication during setup.
Step 2: Install the Logitech pairing software
To pair the keyboard, you need to download and install Logitech's Unifying Software or Logi Options+ software. Logi Options+ is the recommended and newer software for managing Logitech devices, while Logitech Unifying Software or SetPoint are also compatible options. Visit the official Logitech website to download the software for your operating system and complete the installation before proceeding.
Step 3: Pair the keyboard using the software
- Open the Logitech software (Logi Options+ or Unifying Software).
- Select "Add Devices" or "Pair a new device" from the software's main menu.
- When prompted by the software, turn the K520 keyboard off and then back on using its power switch. The software will detect the keyboard and complete the connection.
This is the proper method to connect your keyboard to your computer. Once paired, your K520 will work wirelessly via the 2.4GHz connection through the Unifying receiver.
Troubleshooting common Logitech K520 pairing issues
Keyboard not detected
If the keyboard is not detected during pairing, ensure the Unifying receiver is firmly inserted into a working USB port. Try a different USB port if the first does not work. Also verify that the keyboard's power switch is set to the "On" position and that the batteries have sufficient charge. Replace the batteries if necessary.
Lost the original receiver
If the original Unifying receiver is lost, a new Logitech Unifying receiver can be purchased and paired with your existing K520 keyboard using the Unifying software. The process is the same as the initial pairing: plug in the new receiver, open the software, select "Add Devices," and turn the keyboard off and on when prompted.
Check battery power
If the keyboard fails to respond or maintain a connection, the batteries may be low or depleted. Replace them with fresh ones. A blinking or absent LED indicator near the power switch often signals low battery power.
