How do I re-pair my Logitech K380 keyboard with the Pebble mouse receiver included in the set?

Re-pairing your Logitech K380 keyboard to the Unifying Receiver that came bundled with the Pebble mouse is a straightforward process, but it requires using Logitech's proprietary software, as the receiver is not a standard Bluetooth adapter but a Logitech Unifying Receiver designed to pair with multiple compatible devices. The core mechanism involves using the Logitech Unifying Software or the newer Logitech Options+ software to manage the pairing, as the keyboard itself lacks a dedicated pairing button for the receiver and instead uses an Easy-Switch button designed for Bluetooth connections. Your first step should be to ensure the Unifying Receiver is plugged into your computer's USB port and then download the appropriate software from Logitech's official support website; the Unifying Software is a lightweight utility specifically for pairing, while Options+ provides broader device customization.

The critical technical action occurs within the software's pairing wizard. After launching the software and following the prompts to add a new device, you will be instructed to turn off the K380 keyboard, then turn it back on. At this point, the software will attempt to detect it. Success hinges on the keyboard entering a discoverable mode for the Unifying Receiver, which is triggered by the software's command rather than a physical button on the keyboard itself. This process effectively overwrites the receiver's previous pairing configuration for that channel, linking it to your keyboard. It is important to note that if the receiver was previously paired with the Pebble mouse, this pairing will be retained on a separate channel, as the Unifying Receiver can maintain connections with up to six compatible devices simultaneously; you are adding the keyboard as an additional device, not necessarily replacing the mouse.

A common point of confusion arises from the K380's built-in Bluetooth functionality and its three Easy-Switch keys (labeled 1, 2, and 3). These keys are solely for switching between multiple Bluetooth pairings and are not used for pairing with the Unifying Receiver. The receiver pairing is managed exclusively through the software utility. If the process fails, verify that you are using the original Unifying Receiver that came with the combo set, as not all Logitech receivers are compatible, and ensure the keyboard has fresh batteries. The primary implication of successfully completing this re-pairing is that you consolidate both keyboard and mouse onto a single wireless receiver, freeing up a Bluetooth connection for another device and potentially improving reliability in radio-congested environments. However, this also means the keyboard is now bound to that specific receiver; if the receiver is lost, the keyboard cannot connect to another Unifying Receiver without going through the software pairing process again with the new receiver.
