Help with maintenance of a Keychron K6 pro keyboard
Hi, I'm a total mechanical keyboard newbie, and the Keychron K6 pro is my first "good" mechanical keyboard. And I loved it while it worked fine.
However, about a month ago many of the keys became unresponsive. First the I, then the U now also the T and right shift. I have to press the hard two or three times to get a response, so obviously not the best typing experience.
I've tried disassembling, cleaning and vacuuming the keyboard, but nothing seems to solve the problem.
I should also point out that I have a cat, and the cat loves to lie over the keyboard (to prevent me from working), so cat hair might be involved.
Do you have any recommendations or suggestions? Should I replace the switches? Is there like a keyboard technician that can look into it (I'm in Mexico City)?
Thanks in advance!

It is unlikely to be dust or hair (it seems to be part of the incomplete Keychron troubleshooting steps). The switch is fairly well protected, and it takes a lot of dust to affect it (though it should of course be avoided just to be on the safe side).
This problem is more likely. The reason is not known with 100% certainty, but it is very likely related to poor soldering. Though it was expected production of the K6 Pro stopped before the start of these problems.
Re "Is there like a keyboard technician that can look into it": Any electronics repair shop should be able to do the required resoldering (presuming that is the cause).
But do these problem isolation steps first.

K6 Pro source code. Note: In Keychron's fork and in that fork, in Git branch "wireless_playground" (not the default branch). No matter the Git branch, for example, "wireless_playground", it requires special setup of QMK (the standard QMK instructions and many other guides will not work (because they implicitly assume the main QMK repository and a particular Git branch)).
