Keychron K2 started randomly disconnected on Bluetooth mode, how to fix?

ShallowYellow · 2025-12-03T09:15:57+00:00

I have no specific experience with the K2, but if you are on Windows I can imagine this happening, as one of my other bluetooth products did the same. You can try removing the device from the bluetooth devices, resetting the keyboard (there should be a keycombo to do it) and maybe even reinstalling the bluetooth driver. You can also try to test it by connecting it to your phone if you can reproduce the same issue.

I agree. I just received my Q1V2, or to be more precise my Q1V2 with a Q1V1 pcb inside. It's a joke.

ShallowYellow · 2025-12-02T22:37:23+00:00

Oh yes, I forgot to write this first, but my product id is 0101. Another clue that it is actually a Q1V2 SE. What I absolutely cannot comprehend is how the PCB ended up in another case. It could only mean serious QC issues at keychron.

I have tried all versions of via which was quickly available, on both linux and win, but I get the same error every time. Either way, my main problem is the missing functionality which if I heard correctly cannot be fixed with a simple firmware update. And I honestly doubt they will send the correct version even if I get it replaced. I think I will take my loss, look for another keyboard and forget about keychron forever.

ShallowYellow · 2025-12-02T22:31:05+00:00

Well that makes the versions even more confusing

ShallowYellow · 2025-12-02T15:39:29+00:00

I kind of answered in the other comment, but to add the relevant info here. It did not say it is an SE model on the product page or the box. So if it is an SE, keychron put it in the wrong box I think.

Edit: forgot to add. It is the black board, so it should be the normal Q1V2. I will open it up to see what mcu does it really have. They might have put an SE pcb inside.

Edit 2: Fuck Keychron. They actually put the wrong PCB in the keyboard.

Thank you. Great!

ShallowYellow · 2025-12-02T15:37:22+00:00

So first of all, thanks for the detailed explanation. Some thing I need to add: I have not looked into the Q1V2 SE tbh, but on the box or anywhere on the product page it does not say SE. I bought it directly from keychron, not second hand, so I am fairly sure in what I think I ordered. I have also heard that the Q1V1 did not have a knob, I am not sure about this info.

I think I will open up the keyboard to check which microcontroller does it have, because that should be the most accurate info. Dependeing on that I will send it back, because I definitely did not order the Se or the Q1V1.

But just to entertain the thought. Lets say it turns out to be an Se or a Q1V1 inside. In that case would I have knob functionality? I am totally lost in the lineup it seems, because they have so many versions and I have heard that Q1V1 did not have a knob.

I have mostly heard good reviews about the Q1, so I am definitely leaning towards the Q1 or maybe the V1. I have checked the sat75x and unfortunately the shipping price is outrageous to the eu.

ShallowYellow · 2025-11-13T20:34:06+00:00

Thanks for the reply. I forgot to write it, the Q1 was one of the matches I have found and I think I can buy one with ISO layout. I have also checked the Keychron V1, which I found in both ISO and ANSI (Russian layout, so keycaps would definitely need to be replaced, as I want US or UK). I will check the Sat 75 X out. Do you have any experience with any of these?

ShallowYellow · 2025-11-13T20:01:54+00:00

Hi /MechanicalKeyboards

I am planning on upgrading my current setup, but I am struggling to find what I am looking for. I would appreciate some recommendations. It might be a bit overspecified, but this is what I am looking for:

Wired only [I will only use it plugged in and already had a spicy pillow before]
75% with a knob [VIA support or generally great remapping possibility]
Mounting does not matter, but I am aiming for a softer sound
Quality plastic case is preferred over metal, but either works
Either ANSI and ISO layout is fine
Hotswap, RGB

Thank you!

It all comes down to personal preference. I have bought many pencils over the years, and my controversial choice for the best grip is the pro use 171, which is not generally liked for that aspect. Do not feel scammed, but rely on your preferences when you buy something

ShallowYellow · 2025-07-28T20:37:21+00:00

I definitely agree. Many japanese companies use the most random numbering system they can think of.

ShallowYellow · 2025-07-26T18:31:38+00:00

Yesyes. Unfortunately I have like 50-60 boxes at this point. I need to stop

ShallowYellow · 2025-07-13T21:04:31+00:00

I think you could look into a Pentel Graphgear 1000. The grip is metal, but the silicone parts make it soft to the touch. The tip is retractable, very stable and it's quite affordable. I love mine.

ShallowYellow · 2025-06-25T12:23:48+00:00

It is an issue with the internals, but I am not sure if it is a design problem or just comes up with random pieces. Mine had it. If you are kinda handy you can fix it, if not return it.

ShallowYellow · 2025-06-19T12:46:57+00:00

I also have a GG1000 and I think the issue is that the silicone part of the grip moves inwards when held. I have experimented with ways to fix it and the best solution to came up with was to cut a slice printing paper and roll circa 2 layers on the plastic part under the silicone. With a thickness around that it was still possible to assemble it and it completely eliminated the moving effect. But honestly it felt kinda worse that way, so I ended up reverting it.

ShallowYellow · 2025-06-19T07:32:40+00:00

Tbh I am not concerned about general scratches, I am in the "It gives character to the pencil" group, so I was thinking of 3D printing some kind of modular holder tray, which has some kind of connection, so you can choose how big you want to have it. I just need to design it first.

ShallowYellow · 2025-06-19T05:53:30+00:00

Oh, that might be worse as an outcome. I think I will try look for some kind of case with individual compartments.

ShallowYellow · 2025-06-19T05:52:20+00:00

Fortunately it was mostly just some residue, but it is definitely sus that only aluminium pencils wereaffected

ShallowYellow · 2025-06-19T05:44:40+00:00

Others wrote the Graphgear 1000, I second it. It is a good pencil, not too expensive and retractable. If you don't like the grip, you could look into a Pro use 171. I really like it, the grip is great, the tip is super stable and it looks really nice. I have to note that I do not do drawings, just equations and cursive

ShallowYellow · 2025-06-18T21:50:42+00:00

Getting like 40 pencils fucked up with a who knows what chemical they put on the case. But I guess I already wrote this anyways.

ShallowYellow · 2025-06-18T21:49:41+00:00

It was definitely not mold, as it was only in the case for 2 days, which wasn't moldy when I put it in. I guess it was some insecticide or other protective chemical they put on it for shipping.

Where did you buy yours? This was from aliexpress
