A step-by-step guide to unboxing, pairing, and customizing the Keychron K1 Version 6. Learn how to switch between devices, remap keys via QMK, and avoid common setup mistakes.

Quick Answer

To set up the Keychron K1 Version 6, first charge the battery, then pair via Bluetooth or connect the USB-C cable. After pairing, use the Keychron Launcher web app to customize keys and macros with QMK firmware.

Before You Begin: What's in the Box

The Keychron K1 Version 6 ships with a USB-C cable, a keycap puller, and a quick start guide. The keyboard itself is pre-paired for wired mode, so you can start typing immediately after plugging it in. For wireless use, you'll need to charge the battery first — a full charge takes about 3 hours and lasts up to 34 hours with the backlight off.

One common oversight: the keyboard ships in Windows mode by default. If you're using a Mac, flip the switch on the top edge to the Mac position before pairing. This ensures the modifier keys (Command, Option) map correctly.

Understanding the Connectivity Options

The K1 Version 6 supports three connection methods: wired USB-C, Bluetooth 5.2, and 2.4 GHz (if you purchased the version with the dongle). Bluetooth lets you pair up to three devices and switch between them using the Fn + 1/2/3 keys. Wired mode offers the lowest latency and is ideal for gaming or desktop use.

A trade-off: Bluetooth is convenient but may introduce slight input lag. For real-time tasks like competitive gaming, stick to the wired connection. Also, note that the QMK customization features require the keyboard to be connected via USB-C — Bluetooth mode only supports basic key remapping through the onboard memory.

Step-by-Step Setup Guide

Charge the Keyboard: Plug the USB-C cable into the keyboard and a power source. The LED indicator will glow red while charging and turn off when fully charged (about 3 hours). Don't skip the initial charge — the keyboard may not have enough power for Bluetooth pairing out of the box.
Choose Your Connection Mode: For wired use, simply connect the USB-C cable to your computer. For Bluetooth, set the side switch to Bluetooth, then hold Fn + 1 for 4 seconds to enter pairing mode. The Bluetooth indicator will flash. Select 'Keychron K1' from your device's Bluetooth menu. If the keyboard doesn't appear, make sure it's not already paired to another device. Reset by holding Fn + 1 for 8 seconds.
Set the System Switch: On the top edge of the keyboard, slide the switch to 'Mac' or 'Win' depending on your operating system. This changes the modifier key mapping (Cmd vs. Ctrl, Option vs. Alt). Forgetting this step is the most common mistake — your keys will seem 'wrong' until you flip the switch.
Customize Keys with QMK (Optional): Connect the keyboard via USB-C. Open a browser and go to the Keychron Launcher web app (launcher.keychron.com). The app will detect your keyboard automatically. Click on any key to reassign it, create macros, or adjust backlight effects. Save your layout to the keyboard's memory. The Launcher works only in wired mode. Bluetooth mode cannot load custom layouts — save your layout before disconnecting the cable.
Switch Between Devices: Once paired with up to three Bluetooth devices, press Fn + 1, 2, or 3 to switch between them. The corresponding Bluetooth channel indicator will light up briefly. If switching doesn't work, ensure the target device is within range and has Bluetooth enabled. The keyboard remembers layouts per channel.
