The K380 connects through Bluetooth, not a USB receiver
The Logitech K380 is a wireless keyboard that uses Bluetooth to talk to your device instead of a small USB dongle. This means you can pair it with phones, tablets, laptops, and computers as long as they have Bluetooth built in. Once you pair it the first time, the keyboard remembers that device and reconnects automatically when you turn it on.
The pairing process takes about two minutes and works the same way whether you are using Windows, Mac, iPad, iPhone, or Android. The keyboard has three numbered buttons at the top (Easy-Switch buttons) that let you pair up to three devices and switch between them instantly by pressing the button for whichever device you want to use.
Key Takeaways
- The K380 pairs through Bluetooth settings on your device, not through a separate app or USB cable.
- You can pair the keyboard with up to three different devices and switch between them using the numbered buttons at the top.
- The keyboard needs fresh AA batteries to work, and the battery indicator light shows when they are running low.
- If the keyboard stops responding, turning it off and back on usually fixes the problem without needing to pair again.
- The pairing process is the same on Windows, Mac, iPad, iPhone, and Android devices.
What you need before you start
Check that your device has Bluetooth turned on before you begin. Most phones and tablets have Bluetooth on by default, but laptops and computers sometimes have it switched off. On Windows, open Settings and search for "Bluetooth" to turn it on. On Mac, click the Apple menu, go to System Settings, then Bluetooth.
The K380 also needs two AA batteries to work. Open the battery compartment on the back of the keyboard and insert two fresh AA batteries with the positive end facing up. The keyboard will not pair if the batteries are dead or missing. Once the batteries are in, flip the power switch on the back to the On position.
Pairing the keyboard to your first device
Press and hold the button labeled "1" on the top of the keyboard for three seconds until the Bluetooth light on the front starts blinking. This puts the keyboard into pairing mode and it will stay there for about three minutes while it waits for your device to find it.
On your device, open the Bluetooth settings. On Windows, go to Settings > Bluetooth & devices > Add device. On Mac, go to System Settings > Bluetooth. On iPad or iPhone, go to Settings > Bluetooth. On Android, go to Settings > Connected devices > Bluetooth. Look for "Logitech K380" in the list of available devices and tap or click it. The keyboard will beep once and the light will stop blinking, which means the pairing worked.
Type a few characters on the keyboard to make sure it is working. If nothing appears on your screen, turn the keyboard off and back on, then try typing again. If it still does not work, repeat the pairing steps from the beginning.
Pairing a second or third device
The K380 remembers three devices at once. To add a second device, press and hold button "2" for three seconds until the light blinks. Then go to your second device's Bluetooth settings and look for "Logitech K380" in the list. Tap or click it to pair. The keyboard will beep and the light will stop blinking.
To add a third device, press and hold button "3" for three seconds and repeat the same steps on your third device. Once all three devices are paired, you can switch between them by pressing the numbered button that matches the device you want to use. The keyboard will reconnect to that device within a second or two.
Switching between paired devices
After you have paired multiple devices, switching between them is instant. Press the button labeled "1" to use the keyboard with your first device, button "2" for your second device, or button "3" for your third device. The keyboard disconnects from the old device and connects to the new one right away. You do not need to unpair anything or go into settings.
The keyboard stays connected to whichever device you last used it with. If you turn the keyboard off and back on, it will automatically reconnect to that same device. If you want to use a different device, just press its numbered button.
Fixing common connection problems
If the keyboard stops responding or types very slowly, the first thing to try is turning it off and back on. Flip the power switch on the back to Off, wait five seconds, then flip it back to On. The keyboard will reconnect to your device automatically without needing to pair again.
If the keyboard does not respond at all, check that the batteries are not dead. Look at the battery indicator light on the front of the keyboard. If it is off or very dim, replace both AA batteries with fresh ones. If the light is bright and the keyboard still does not work, try unplugging any USB devices from your computer and turning off other Bluetooth devices nearby, as interference can sometimes cause problems.
If you want to remove a device from the keyboard's memory and pair a new one instead, press and hold the numbered button for that device for seven seconds instead of three. The light will blink faster and then turn off, which means that device has been erased. You can now pair a new device to that button by pressing it for three seconds.
Battery life and maintenance
The K380 runs on two AA batteries and typically lasts several months before you need to replace them, depending on how much you use the keyboard. The battery indicator light on the front shows you the status. A bright light means the batteries are good. A dim light means they are running low and you should replace them soon.
Keep the keyboard away from water and extreme heat. If you are not going to use it for a long time, flip the power switch to Off to save battery. The keyboard does not need any software installed or any special charging cable — just batteries and Bluetooth.
Frequently Asked Questions
Can I use the K380 with my phone and laptop at the same time?
No, the keyboard can only connect to one device at a time. However, you can pair it with both devices and switch between them by pressing the numbered buttons. When you press button 1, it disconnects from your laptop and connects to your phone instantly.
What if my device does not show the K380 in the Bluetooth list?
Make sure the keyboard is turned on and the battery indicator light is on. Press and hold the numbered button for three seconds to put it into pairing mode — the light should blink. If the light does not blink, the batteries may be dead. Also check that Bluetooth is turned on in your device's settings.
Do I need to install any software or drivers?
No. The K380 works with standard Bluetooth and does not require any software, apps, or drivers. Just pair it through your device's Bluetooth settings and start typing.
Why does the keyboard keep disconnecting?
Low batteries are the most common cause. Replace the AA batteries with fresh ones. If the batteries are good, try moving the keyboard closer to your device, as Bluetooth works best within about 30 feet. Interference from other wireless devices can also cause disconnections.
Can I pair the K380 with a device that does not have Bluetooth?
No. The K380 only works with Bluetooth. If your device does not have Bluetooth, you cannot use this keyboard with it. You would need a different keyboard that uses a USB receiver instead.
