r/Keychron on Reddit: Keychron K2 HE firmware questions
April 5, 2025 -

I'm considering getting a K2 HE and I have some questions regarding the software.

  1. Can I create combos using the Launcher? This is important to me as I use a number of them -- to many to replace using layers.

  2. Am I really limited to only two layers per OS? I can understand that the default configuration only needs two layers but once I want to add my own that is simply not enough.

  3. Can I flash the board with my own version of QMK? This would basically fix the other problems as I can just update everything as I like.

  4. If the K2 HE can't support these requirements, is there another Keychron 60-75% board that can?

r/Keychron on Reddit: Keychron K2 HE & the state of analogue keyboard gaming support
December 21, 2024 -

I start this topic for two main reasons: On one hand to share my impression of this particular feature of hall effect keyboards, the analogue input and to look for some advice, tipps & tricks, workarounds from the community, as I'm completely new to this and I reckon many of you are not. :)

Yesterday I received my Keychron K2 HE. I don't wanna waste your time with general impressions, just this: I haven't been much into "premium" mechanical keyboards before that, just used a Logitech mecha. This one feels so much better in comparison and I'm going to keep it.

One of the main reasons I supported the Kickstarter for this keyboard was the idea of analogue gaming. A longstanding problem for me in many games was the question: Does it have a walk button? But if the keyboard itself can emulate a gamepad, I wouldn't need one.

Spoiler: It's a mixed bag.

First the basics. You'd always need a software layer on top of the keyboard, when you want to use the gamepad function. Like Steam input. Steam recognizes the K2 HE as a game controller regardless whehter your current mode has gamepad emulation enabled or not. You then have to initialize and configure it with Steam input, pressing buttons analog to gamepad inputs. If you're finished, Steam can then translate the set keyboard buttons as generic game controller input into games that support it.

I made a basic tutorial with pictures HERE

And this is the main divider: The support. Because some do, some don't. With some shades of grey inbetween.

Basically there are two types of games:

The ones that support any kind of input, even simutaneously, without a hickup. And those which do not. Among the first category are generally games who have native multi axis supports like flightsims, or games like Mech Warrior 5 Clans. For any other game it's a case by case situation and has to be tested.

To show these "shades of grey" here are some specific examples I tested, as even games who fall into the first category can have problems of their own:

  • Indiana Jones & The Great Circle - FULLY COMPATIBLE (through Steam Input); no stopping of input or hitching of graphics, even when combining Frame Generation with a fps limit

  • Cyberpunk 2077 - FULLY COMPATIBLE (through Steam Input)

  • Star Wars Outlaws - COMPATIBLE, but technical hickups; if you combine Frame Generation with a fps Limit (and I know this is generally not a good ide, but it works normally in this game) and then combine the two inputs - Mouse for looking, K2 HE for emulating a generic gamepad - frametimes go wild. Only without a fps limit does it work. I suspect this is down to how Nvidia Reflex handles different types of input.

  • Dead Space Remake - COMPATIBLE, but issues with the controls. The game always sees the K2 HE as a controller and when I first booted into the game I was constantly ADS and some actions like kicking happened at random; workaround is to erase all controller inputs you don't have mapped to the keyboard from the ingame menu and only leave those you need. For instance I only mapped left stick controlls to the K2 HE. But even still with this workaround the camera can jump when you walk to the side while also aiming.

  • Horizon Forbidden West - NOT COMPATIBLE; like at all! The game has a hard cut between controller input and mouse/keyboard input. When I walk using gamepad emulation with the K2 HE and move the mouse, Aloy stops dead. Not working.

  • Warhammer 40.000 Space Marine 2 - NOT COMPATIBLE; the game supports brand controllers by default - DualSense, Xbox Controller - but does not work with Steam Input at all. You'd have to disable it when you want to use a brand controller. Thus a generic controller or amulation of such through Steam Input is not supported

So, to sum things up, the one feature I was most looking forward to is a bit of a let down. But this also the reason, like mentioned initially, why I started this topic.

If you know any tipps & tricks, workarounds, please let me know. I guess Steam Input is not the only software layer I could wrap around the generic gamepad the K2 HE is emulating, so maybe this could solve some of the problems. Maybe it is possible to emulate an Xbox controller or a DS4? Of course I tried DS4Windows, but it does not recognize the K2 HE.

Within the configuration software (via browser) for the K2 HE there is a peculiar setting:

https://i.imgur.com/NC9KBS7.jpg

"Xbox". Natuarally I enabled it, hoping it would present either DS4Windows or Steam Input an emulated Xbox controller, but it just doesn't. It seems to do nothing and not work at all, unless I missed something.

So...what are your impressions of this glorious new keyboard analogue gaming world we're living in? :D

Thanks for making this post, although I cannot add much useful information. Just received my keyboard yesterday and having not much of a clue of the technological side of analog controller emulation I somehow expected it to just work out of the box regardless of what game you play. So I've spent a few hours messing around in the web app and watching youtube videos to see if I have missed anything because I couldn't get it to work. There is also little to no information apart from it being listed as a feature on the kickstarter page and probably on the official webpage. In the web app there is not a single clue to what the settings are doing. I tried setting it up for Trackmania (Steam), so I mapped RT to W (accelerate) and LT to S (brake/reverse). Somehow they turned out to be the opposite of each other and the S button only registered a quarter press although I pressed it down all the way. Fast forward to today it doesn't work at all. The only other game I tested it on was Black Ops 6 (non-Steam) and it didn't work. At least, after reading your post, I know why. So thanks again for letting me know it wasn't just me.

When it comes to HE keyboards, everything is about the software support. It is entirely asinine to purchase any HE keyboard which doesn't already have solid software support on the chance that it might exist some day. What is even more asinine is that basically no keyboard review will even bother to mention this. (Which shouldn't be surprising, because they are mostly advertisements anyway.)

r/Keychron on Reddit: K2 He firmware update
September 10, 2025 -

I'm attempting to update keyboard firmware as the launcher says but device with "boot rom open" won't show up. I'm pressing ESC while connecting the cable and keyboard goes unresponsive (as it should)?

Just download and install it using their instructions. At the bottom, for QMK.

Re "I'm pressing ESC while connecting the cable and keyboard goes unresponsive (as it should)?": Yes, it should. You can positively verify flash mode (AKA firmware update mode AKA bootloader mode AKA DFU mode). It also works on Windows (but see the prerequisites below (at least #1 and #2)). Prerequisites on Windows It is required to install some drivers to flash/update the keyboard firmware. For example, use QMK Toolbox ( this Keychron page has some details on the driver installation (near "Run as administrator")). Prime suspect #1: The notorious Thrustmaster AKA Guillemot driver is not interfering (if it happens to be installed). If it is installed, it may or may not be possible to disable without uninstalling it. Prime suspect #2: SignalRGB is not active. It is allegedly possible to disable it for the current Windows session, without the need to uninstall it. Though it may not affect flashing from the command line (see below), only the configuration tools. If all else fails, do it from the command line (even if not) In a pinch, it is also possible from Linux booted off a live USB stick , say, LMDE (though dfu-util would have to be installed for every session, for example, sudo apt install dfu-util from the command line). BIOS configuration changes may or may not be required for that to work (or at least entering it to select the boot device). Flash from the command-line (with the keyboard in flash mode ): dfu-util -l # Verify bootloader mode dfu-util -a 0 --dfuse-address 0x08000000:leave -D my_awesome_Keychron_K2_HE_iso_encoder_keyboard_firmware.bin It also works on Windows (if the drivers are installed—see #1 above. And if there isn't interference by other software). References K2 HE JSON files for Via (near "K2 HE ISO RGB keymap"). They are also on GitHub . Note: The JSON section should not be confused with the firmware section. K2 HE (main) firmware (near "K2 HE ISO RGB version firmware"). Note: The firmware section should not be confused with the JSON section.

r/Keychron on Reddit: "install drivers" within the driver.exe for firmware update.
March 11, 2025 -

Hello,

I followed the instruction on launcher.keychron.com, updated the firmware and it worked without problems. Apart from one issue. There is a point where I selected Tool->install drivers.

I guess this means install the drivers on windows, and this drivers are always active.

a) There is no application. I found the folder AppData\Local\QMK this is not really a regular application installation. No entry in the windows startmenu, no entry in settings->app and the executable driver.exe is in the windows download folder.

b) If these are windows drivers, how I can deinstall it? Simple delete the appdata folder?

btw.

c) It's really nice that I have 1.1.0 now on my q6 max. But where is a changelog? I find only "Added debounce, LKP, Per-key RGB/Mixed RGB, as well as backlight off" on the Firmware and JSON Files website.

r/Keychron on Reddit: Do these keyboards need driver/software updates?
June 24, 2025 -

I bought this k8 pro a little over two years ago and it's been great ever since. However, I don't recall ever installing any software for this keyboard, all I did was program the buttons on a website back when I bought it and that was it.

Ive went through a few PC resets and never recall installing anything unlike my mouse which requires the manufacturers software to change settings.

I never had to do it for the keyboaord since all my settings retained on it. My question is that do these keyboards need any software updates? Is it something I need to keep up to date or are these keyboards just set it and forget it?
