Title: Keychron K3 Max number row not working
Post by: Inventel on Thu, 07 August 2025, 15:55:41

Hello, I purchased a used Keychron K3 Max ISO at a good price. When it arrived, I noticed that the entire row of numbers and the keys you see in the photo don't work. The keyboard is new and shows no signs of use, so I decided with the seller to keep it and pay only €10.

Can you help me fix it? The RGB LEDs all work perfectly and the pcb is only a little oiled from the switches but I can't find any problems.

Here are the photos of the PCB:
