A word of caution before we begin:
This article will contain some dirt-horror as we're going to tear apart our very first Redragon K556 that we purchased back in 2019, then later used heavily for work. This article is almost an addendum to the previous one, where we fixed two K556 keyboards with very minimal effort. But we also wanted to follow up on what happened to the very first keyboard. We got the nice keycaps that are not being made anymore.
Put away your lunch and read onward.
