I have a keychron k4, it’s been fine for about 5 years (I got it second hand but it was pretty new) lately I’ve been noticing a couple of keys will occasionally not work the first time they’re pressed (the ‘U’ and ‘Tab’ specifically). I took the caps all off and gave it a good clean but it’s still happening. My next idea after some research is to try applying contact cleaner, bit I haven’t gotten around to that yet.
