Introduction

This guide will show you how to replace an unresponsive, faulty, sticky, or worn-out key switch on the Attack Shark K86 mechanical keyboard. Mechanical switches can fail over time from dust, wear, or other electrical issues. Replacing a single switch or a few keys is a quick and cheaper repair that can fully restore the function of your keyboard.

The Attack Shark K86 uses hot-swap sockets, so most MX-style switches will work as replacements, provided the pins match the keyboard's hot-swap layout.

Unplug the keyboard from your computer.
Make sure cable is fully removed so no power is reaching the keyboard.
Working on a powered keyboard can damage the internal components.
The keyboard lights turning off is a clear indication that it is fully unplugged.

Use your keycap puller and position the prongs underneath the edges of the keycap.
Pull straight upward with gentle, even force.
Do not twist or pry sideways, as this can crack or damage the keycap.
If the keycap feels stuck, gently wiggle while pulling, it should come off without much resistance.

Inspect the area around the switch for dust, hair, crumbs, or other debris.
Use gentle cleaning tools such as compressed air, a small brush, or a Q-tip with small amount of isopropyl alcohol to remove debris.
Do not apply isopropyl alcohol directly to the keyboard because it could damage it.
Cleaning prevents debris from entering the switch socket or interfering with the switch installation.

Use your switch puller and place the hooks under the plastic clips on both the top and bottom of the switch.
Hold the keyboard steady with one hand, with the other hand, squeeze the puller firmly and pull the switch straight upward until it pops free from the hot-swap socket.
Avoid twisting or pulling too hard, which can damage the board's sockets.

Examine the metal pins on the bottom of the new switch and ensure they are straight.
Align the pins with the holes in the hot-swap socket.
Placement matters so take the time to align.
Once the pins are correctly aligned, press the switch straight down until you hear or feel a soft click, confirming it is fully seated.
