Introduction
Use this guide to remove and replace a keyswitch on the Logitech G915 TKL keyboard. A keyswitch may need to be replaced if the key is no longer registering inputs, and you've confirmed that the issue isn't the keycap.
Before using this guide, ensure that the issue with your key isn't due to a broken keycap or a buildup of dust or debris in the area around the key.
Steps 7 and 8 require you to desolder the broken keyswitch and solder a new one in place.
A Phillips #00 Screwdriver is required to complete this guide, as well as a soldering iron, solder, and a desoldering braid.
