Key press letter/character repeating mechanical keyboard

[Mech Keyboard]

Hi I bought a Corsair K95 platinum mechanical keyboard from Amazon a few years ago. 

The keyboard has been great until recently when I started having issues with my E key repeating multiple times on one button press. It happens frequently enough that it's noticeable and would only double up this one particular key.

I keep the keyboard very clean, but removed all keys and cleaned out each key with compressed air etc and checked for any obstructions but couldn't see anything. I'm running the latest firmware for the device, Bios and on screen keyboard checks and checked the repeat key frequency but it just keeps happening with this one key, maddeningly.

I absolutely love the keyboard  and am interested to hear if anyone else may have had this problem and had any other suggestions.

I'm not sure if it's the underlying key switch itself is gone..but I want to try and fix it as I'm out of warranty with amazon sadly.

Thanks in advance for any help 🙂
