Introduction

The HyperX Alloy Origins mechanical keyboard provides RGB lighting to each of its keys through switch-mounted LEDs. Therefore, it is necessary to remove an entire key switch whenever its corresponding LED needs to be replaced.

Before beginning LED replacement, be sure to visit the troubleshooting page before making permanent changes to the PCB! This guide should only be used in the event that one or more keys do not light up while the remaining key LEDs are properly functioning.

Usage of a desoldering iron or a desoldering pump (alongside a normal soldering iron) is strongly recommended. The HyperX key switches contain pins which make it difficult to wick away solder. This guide uses a sole soldering iron for demonstration purposes only.

What you need

Step 1

              Toggle Indicator Tab               

• Locate the toggle indicator tab on the top right corner of the keyboard.

Step 2

• Insert the metal spudger or some other separating instrument into the right crevasse between the tab and the keyboard.
• Lift up gently on the tab, while holding the left side of the tab down.
• The tab can spring upwards upon removal. Eye protection is recommended during this step.

Step 3

              Backplate               

• Flip the keyboard over so that the backplate is facing you.

Step 4

• Remove the rubber feet on the four corners of the backplate.
• When reassembling, use an adhesive to reattach the feet. A silicone rubber adhesive is recommended.

Step 8

              Key Switch               

• Identify the key switch to be replaced.
• Remove its keycap by carefully prying it off of the keyboard with your fingers.

Step 10

• Plug in and turn on your soldering iron.
• Do not touch the metal end of the soldering iron while it is powered on. Allow the soldering iron to cool before stowing it away.

Step 11

• Melt the solder surrounding the four pins of the switch’s LED, and the two lower pins of the switch body.
• To remove the melted solder, use a desoldering iron, a desoldering pump, or desoldering braid.
• The exposed switch pins are susceptible to damage from the soldering iron. Avoid applying heavy pressure to mitigate pin bending.

Step 12

• Using a spudger or another metallic instrument, firmly press down upon the exposed plastic of the switch. This will separate the switch from the rest of the keyboard.
• If the switch’s pins will not separate from the keyboard’s PCB, continue applying the soldering iron to the pins to melt any residual solder.

Step 13

              Key Switch LED               

• Gently pull the LED off of the switch.
• Do not break the LED pins while it is still attached to the switch.

Gently pull the LED off of the switch.

Do not break the LED pins while it is still attached to the switch.

To reassemble your device, follow these instructions in reverse order. Note that when reattaching the switch back to the keyboard PCB, the switch needs to be held in place behind the keyboard while soldering.
