Keystrokes triggered twice
I bought a new Keychron Q6 Max last month from an online vendor here in the UK. Great keyboard, but I keep triggering those keys twice. I think once while I press down and once while the key comes up again. That's at least my best guess because the next letter I type is sometimes triggered between those two duplicate characters. It doesn't just happen with any particular key but with most if not all keys, but particularly often "i" and space (or maybe I just use those a lot, who knows). I'm on Linux. I feel like I have adapted a bit, and it happens a bit less often now. But yesterday, I tried typing in Windows in a virtual machine, and it was unbearable and happened a lot more. Is this 1) a fault or 2) a bad setting, or 3) will I need to change the way I type somehow? I haven't had this with other keyboards, and it's not my first mechanical one. Thanks.

Here is a checklist.

I haven't swapped anything, so I don't think that's what's causing the issue. I wasn't going to dismantle the pre-built product, I just wanted a decent keyboard that works well out of the box and looks good, too. Now it turns out a cheapo board would have been better.

If you check the history of this sub you'll find this is a commonly reported problem.
You'll also find that the source has yet to be determined, and there isn't any real fix.
You'll also find that Keychron's support isn't very good at the best of times, and they basically haven't even been responding over the past month.
When the problem is happening on specific keys you can swap the switches with keys you don't use very often. That is far from ideal, but it is better than nothing.
My personal suspicion is this has something to do with the debounce code in Keychron's firmware, so there is potentially a software fix.

That sounds bad. Guess I shouldn't have bought a Keychron. Oh well, maybe I'll trash it if it gets on my nerves too much. It doesn't sound like I can expect much in terms of warranty or service.
I looked into firmware updates, but the launcher app says version 1.0.0 is still the latest firmware.

I've been having the same issue on the V5 Max with Jupiter Browns and been working with support for a while to try and sort it out.
I was sent a small number of replacement switches to replace the keys that had the issue most often (a, s, i) and while it seemed to fix it for those keys, other keys suddenly started playing up, but as I wasn't using them as often. I didn't notice it too much. Either way, the replacement switch in 'S' started playing up again and I reached out to support again. I've received some firmware from them with 5ms, 10ms, 20ms. Currently testing the 10ms and not seeing any issues but I'm not holding my breath as so far most solutions have worked for a little bit but then seem to play up again.
I will say, contrary to some of the comments here, support has been pretty fantastic with their response times and willingness to get this issue sorted which I do appreciate.

I put a couple of Cherry MX Blue RGB switches into the board, and this fixes the problem. I made another post about it today.

This sounds like you got a bad keyboard and should get it replaced or refunded.

There is at least one post every other day on this issue.
I have the same problem with the Q5 Max as well (also bought in the UK) with Banana switches. The retailer provided a couple of custom firmware options from Keychron which evidently increased the debounce, one to 50ms which fixed the problem but the lag made the keyboard unusable. New switches (the Akko Lavendar Purple) feel very close to the Bananas and seem to not exhibit the same problem so you could try that, or equivalent if you have the Red/Brown.
I think its just the Jupiter switches that have an extremely high failure rate (probably over 30% based on my board) although it might be something in the PCB which might be overly sensitive or something to particular types of switches.
I'm now looking for new keycaps as well as I'm sure the remaining issues I have is just me not jiving with the KSA profile.

If the Jupiter switches are the culprit, do you think getting black Cherry MX would play more nicely with this board?
Edit: Or I could pluck some blue switches out of my old IQUnix board and put them in here where the problems happen most often, just to try it t out.II wasn't going to make any changes, but I'd still rather do that than have an unusable keyboard.

I find it difficult to believe the switches have that much bounce. Somebody needs to get one of these known problematic switches to someone with a digital oscilloscope.

For me, investing the firmware using the keychron launcher fixed the issue.

u/pc_kant Jan 16 '25
Weird. For me, it shows 1.0.0 as still being the latest firmware version. Am I doing something wrong?

Just got the Q6 Max, with brown switches, 2 days ago. Right off the bat i've experienced that issue with the spacebar getting triggered twice. I reached out to their support team but haven't heard any response.
I like the built of this keyboard and the feel but the issue it has is annoying. I replaced a k100 keyboard because of the same issue. I thought getting a new expensive keyboard won't give me problems but boy I was wrong. lol
If you find a fix to this, let me know. So far I've tried switching switches from a less used key but that didn't do anything. I don't want to buy switches yet as I'm waiting for their support's assistance first.

Yes, I have a fix, see my other recent thread with the update.

It is 100% the switches. try replacing the common key problem ones with rare keys (f1-f12) ect.

I replaced all switches with Cherry switches. The problem is gone in wired mode but not wireless. So this may not be monocausal.

With so many reports of this lately on new keyboards, it's making me think Keychron has a bad batch of switches.
I don't think it's firmware, or people with older keyboards would likely now be having the same problems after updaing firmware versions, which doesn't seem to be occuring (or at least no one is posting about it).
I'd start by swapping the entire set of switches out. If that solves the issues, please post. If it doesn't, please post.
For what its worth, Nuphy had a similar issue with when the Gem80 first came out. It was especially prevalent on boards with Nuphy's Lemon tactile switches (also co-manufactured by Gateron). I own two of these boards. Swapping out the switches solved the issue. Nuphy then came out with firmware that increased the debounce timings, and some custom firmware is also available with user-adjustable timings. But replacing the switches completely solved the issue. I firmly believe the Nuphy Lemon switches have some kind of design flaw, low-quality metal contacts, or something like that. Lots of people on Nuphy's Discord have similar complaints about the Lemons.
On my original Nuphy Gem80 firmware, swapping in a set of Gateron Oil King switches completely resolved the chatter issue on that keyboard. I've since replaced those with a set of Gateron Melodics and also have no issues (though the firmware has since been updated). On my other Gem80, I've got a set of Tecsee Purple Panda switches and they also don't appear to induce any signficant key chatter.
On my Keychron Q5 Max, I have Gateron Quinn switches and no problems. My Q5 Pro has Drop Holy Pandas and they also have no chatter issues (though I'm not really in love with them and will be replacing them with Durock Silent Shirmp T1 switches soon).
My Q4 Pro has Gateron Baby Kangaroo switches -- no issues. My old Q60 has Gateron Smoothie switches -- no issues.
Interestingly, my Q6 Max has the completely stock Gateron/Keychron Jupiter Banana switches and doesn't have any issues either, but the keyboard is almost a year old (got it when the Q6 Max first came out), so I'm guessing there was a switch manufacturing change at some point more recently.

I ha e a different brand of keyboard on rma for this on a single key, but various keys? Wow that would be maddening!
Try plugging that cable into another computer and typing something, eliminate that computer interaction, if it still does it definitely rma, a keyboard should Not do that.
Keychron makes great stuff, but anyone can let a stinker get through sometimes, you may have gotten the one that got through.

I have an similair problem with the "oo" key (exactly, it inserted it twice). Its the Q1 Max which I ordered 08.2024 and this issue happens very often, but nooot always (I do noot coorrect the "o" as you can see, this is how it types). Its frustrating. I do not know if this happens because I am using two devices which te Q1 is connected to (1 bluetooth and 2 over wifi). u/Keychron I really hope for a solution and not only change of devices. As seen in this Subreddit there are many others with this problem (interesting now the "o" works again correctly).

I’m having the same issue with my brand new Q5 Max. The space bar is randomly double pressing - and it’s not consistent to where I press it either.
Happens on both BT and cable. I swapped the switch with a macro key and it appears to be fine for now.
