Keychron Q3 Max QMK/VIA Wireless Custom Mechanical Keyboard

Feels nice. Looks good. But tthe keyboard has a major issue with double typing keys. Out of the box, I have several keys that double type. I saw a review saying that but bought this keyboard anyway and now I am regretting it.

I unfortunately started getting the multiple key inputs issue less than a month into owning this keyboard. There are two fixes I've found here. First, press the key down *hard* so the switch clicks back into the socket, that way it's not bouncing. Sometimes they seem to get dislodged easily in this keyboard. Second, disable NKRO; function+n, by default. This is enabled by default and allows more key presses than normal, which can increase the "double click" issue.

As mentioned before, this keyboard is a joy to type on, feels great, and the lights are fantastic. It's a real shame that such a premium keyboard has such strong problems, and requires me to disable a premium feature to get the thing to work correctly. I love this keyboard, but my experience makes me hesitant to purchase higher end keychron keyboards without doing more research.

I have used many, many keyboards over the years (most recently coming from a Topre RealForce) and this is by far the best. Fantastic keyboard build quality, excellent keycaps profile, and super smooth Gateron Jupiter Banana switches. Love the layout, my fingers are hitting everything correctly without hesitation, increasing my typing speed a lot (fewer corrections). Re-programming key mappings was super easy.

Briefly swapped in Cherry MX2A RGB Silver Speed switches, but found the Gateron Bananas to be better (they were close though): smoother typing and slightly longer travel made for an overall better experience.

Highly recommend the Keychron Q3 Max!

I purchased this keyboard in June 2024. I needed a keyboard that could support multiple Bluetooth connections for all my devices. This one looked cool and ticked all my boxes. I was very excited when it arrived - everything from the packaging to the device itself looked very high quality. And for about two months I was very happy with what I got.

But then I noticed while gaming one night that something was off. I'd press a key to open a menu and then it would immediately close. I had to keep trying until it stayed open. Then the next day while working, I noticed that my E key was double typing. A short time later, another key started double typing. I found that remounting the switches helped, but this proved to be temporary. Keychron sent me some replacement switches to use when this happens, but I'm asking myself why this is even necessary for a keyboard that cost me over $200.

6 months later, I'm still seeing double typing issues pop up occasionally. This is a real shame. I've never experienced this issue with any other keyboard. I really want to like this thing, but this is a massive (and frankly, basic) flaw. I just can't recommend this keyboard - don't risk this issue for this price.

I want to desperately love this keyboard. Purchased a Q3 Max from Amazon with banana switches. At first, it worked fine. Now, about 3 months later, I'm getting excessive key chatter (multiple activations on a single key press).

I've moved the switches around and the problem persists. I've flashed firmware. I've contacted support and they have tried to be helpful but directions are at times vague and supremely unhelpful.

On Reddit, I've received advice saying that the board may need to be resoldered. That is unacceptable at this price point. Search "key chatter keychron" on Reddit and you'll get PLENTY of results from other folks running into the same problem.

What a disappointment. I love how it looks, and how it types, I just wish it WORKED correctly. I've purchased many mechanical keyboards in the past ten years, none of them nearly this expensive, and had no issues with any of them.
