r/Keychron on Reddit: Why doesn't it have software for the RGB (and some K2 V2 hotswap questions)
December 20, 2020 -

Even cheap Chinese boards have RGB and macro software that allows you to deeply customise every part of your keyboard.

I really want to get the hotswappable version of the k2. It seems to have everything I want (bt 5.1 + 4000 mah battery, 75%, hot swappable etc) but I'm also super annoyed with not having RGB software.

I checked the keychron site and it seems their quality has gone to shit. Which really scared me off with people having terrible experiences according to the reviews esp with customer service. The key caps they provide are even blurry apparently. That said I am planning to order from a Dutch site that claims to offer 2 year warranty + 90 day return policy (super uncommon for Dutch sites and sorta hard to believe)..the price is higher than on the keychron site though (115 euro vs 100$)

I kinda like setting different colours for different parts of the keyboard. And this basically won't allow me to do that. They supposedly are working on software but also promised to release it in the second half of 2020 which is over in a few days from now.

Lastly I heard the brightness of the k2 v2 is lacking and that brightness is wildly different from version to version etc. E.g. People say the k8 has super dim brightness compared to the original k2. I mostly work in dark rooms and prefer it pretty bright.

Anyway, any update on their driver software?

P.s.

lastly

On their site they recommend NOT updating the firmware for their keyboards as they apparently might get bricked in the process. This doesn't instill a lot of confidence

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: K2 HE web app
November 17, 2024 -

Hi. Just got my k2 he and I can’t connect to the web app on 2.4ghz mode.

When I attempt it, it says keyboard firmware not support wireless. So I connected it via cable and updated the firmware and tried again on 2.4ghz, still the same sadly.

Anyone have the same issues or am I doing something wrong?

Thanks in advance for any input :)
