@ceo_of_monoeye_dating @sjw get a mechanical one where you can swap out the switches. That way, when your keys break you can easily swap em out. Heck, you can even pull a switch from a key you never use like Ins or something.
@roboneko @ceo_of_monoeye_dating @sjw if depends on the board. Some may be soldered on. The ones that can be swapped, there are two main kinds that have different amounts of pins. I think it's like 3 and 7. However, 3 pin switches will still work in a 7 pin board. 7 pin switches will work in a 3 pin board, you'll just have to cut the remaining pins off.
Just look up your model and see if you can remove the switches without needing to desolder anything, and check to see what switches it is compatible with.
My last board had soldered on switches, so when they began to die there was nothing I could do about it. I bought a new one from Glorious Gaming that has hotswappable switches to future proof myself. It was the best bang for the buck I could find (without resorting to a redragon keyboard ew). Only issue would be if the board itself got damaged somehow, like from a bad spill or being dropped.
That said, I have this problem with more than just one key - the o key also have this probleme, quite a bit.
