Can a Logitech K270 Work Without a Receiver?
On this page
Short answer: no. The Logitech K270 has no Bluetooth and no USB cable port. It only talks to your computer through a small Logitech USB receiver over 2.4 GHz. If the original receiver is lost or broken, the fix is a replacement Unifying receiver, which you pair to the keyboard in a couple of minutes.
Below is how to check which receiver you need, how to pair it, and what to do if you really want a keyboard with no dongle at all.

Any guide that tells you to press a "Bluetooth button" on the K270 or plug it in with a cable is wrong: those options don't exist on this keyboard.
Step 1: Check which receiver you need
The K270 sold on its own comes with a Logitech Unifying receiver, recognisable by a small orange star-shaped logo. That is the type you need as a replacement.
- Unifying receiver (orange star logo): works with the K270 and up to five other Unifying devices on the same receiver.
- Logi Bolt receiver (green "Bolt" logo): does not work. Bolt and Unifying are not compatible with each other.
- Plain nano receiver with no logo: usually pre-paired to the devices it was sold with (common in keyboard-and-mouse combos) and can't be re-paired to your keyboard.
If your keyboard came as part of a combo set and its receiver had no Unifying logo, contact Logitech support with the model number from the label under the keyboard before buying anything.
Already have another Logitech mouse or keyboard with a Unifying receiver? You can pair the K270 to that receiver instead of buying a new one.
Step 2: Pair the K270 to the new receiver
- Plug the Unifying receiver into a USB port on your computer.
- Install Logitech's pairing software. Logitech now recommends Logi Options+ for Windows and macOS. The older Logitech Unifying Software can still be downloaded from Logitech's support site, but Logitech no longer maintains it. On Linux, the free tool Solaar does the same job.
- Start the pairing (in Unifying Software: open it and click Next; in Logi Options+: add a device and choose the Unifying receiver option).
- When asked, slide the K270's power switch off and back on. Make sure it has fresh batteries.
- Type a few letters in the test box to confirm, then finish.
You only do this once. After that, the keyboard connects automatically whenever the receiver is plugged in.
K270 not connecting? Common fixes
| Problem | What to try |
|---|---|
| Keyboard dead, no response | Replace both batteries and check the on/off switch under the keyboard. |
| Pairing software doesn't find the receiver | Try a different USB port (directly on the PC, not a hub) and restart the software. |
| Pairing fails or times out | Bring the keyboard within 30 cm of the receiver, switch it off and on when prompted, and try again. |
| Lag or missed keystrokes | Move the receiver away from USB 3.0 ports, metal cases and Wi-Fi routers, or use a short USB extension to bring it closer to the keyboard. |
| Wrong characters typed | Check the keyboard layout/language in your operating system settings. |
| Some keys don't work | See our guide on how to unlock a keyboard (Num Lock, Fn Lock and filter keys). |
Want no dongle at all? Choose a Bluetooth keyboard
If the reason you're searching is that you don't want a receiver (for a tablet, a laptop with few USB ports, or a TV), the K270 isn't the right keyboard. Logitech's Bluetooth models connect without any dongle, for example the compact K380 and its successor Pebble Keys 2 K380s, or full-size models such as the Signature K650 (Bluetooth or Bolt). Our guide on how to connect a wireless keyboard covers Bluetooth pairing on Windows, Mac and Android.
FAQ
Does the Logitech K270 have Bluetooth?
No. It only works with a Logitech USB receiver.
Can I connect the K270 with a USB cable?
No. The keyboard has no USB port, so it can't be used wired.
Will any Logitech receiver work with the K270?
Only a Unifying receiver (orange star logo). Logi Bolt receivers and pre-paired nano receivers without the Unifying logo won't work.
Can one receiver run my K270 and my mouse?
Yes, if the mouse is also Unifying-compatible. One Unifying receiver can hold up to six Logitech devices.
How do I put the K270 into pairing mode?
There is no pairing button. Start pairing in Logi Options+ or the Unifying Software, then switch the keyboard off and on when the software asks.
