Huntsman Elite dead key (not working and stuck in red)?

Hello everyone

Today I turned on my computer and my keyboard showed this two "red" lights. The key '2' is completly dead, not working, but the strange thing is that is has a red light on it (some kind of warning)? Attached the keyboard picture:

I have tried:
- Using another computer with synapse 3 (same problem)
- Reseting the keyboard as shown in (https://mysupport.razer.com/app/answers/detail/a_id/1697/~/how-to-fix-an-unresponsive-razer-keyboard-with-a-hard-reset-or-by-exiting-out)
- Erasing all profiles and macros
- Updating firmware

Do you know if this is some kind of hardware (fixable) problem, or it is a software problem that has to be solved in some other ways?

Thank you so much :)
Kind regards
