I have the problem that my A button sometimes doesn't work in Fortnite and GTA, ie. That she sometimes leaves, but then sometimes doesn't react, for example I don't go left at all. I've already restarted the PC, cleaned the keyboard (SteelSeries Apex 7 tkl). I don't know what the problem is and would ask for your help.
Since it only affects one button, I would say that the switch gives up the ghost.
If you can just solder a new switch, in my experience a new switch always costs around 5 euro so you can risk that.
Keyboards break after a few years. Especially with frequently used keys and A is one of the most used keys in gaming.
In my experience, the tastas for 10-20 euro even last longer than those for the multiple price.
I bought the keyboard for Christmas
If this is a wireless keyboard, you can still change the batteries.
Otherwise, write directly to the dealer and complain that the thing is broken.
Yes, I will do it, but is there nothing I can do?
The keyboard is only 4 months old
Never again buy a keyboard that costs 150 euro and then dares to break so quickly. It's best to never buy a tasta for hundreds again.
My experiences with alleged premium products are no different from yours. I have never had anything that broke as quickly as the deluxe mouse that I had at one point or another.
I would return the keyboard or send it for a repair because this keyboard broke something.
