Replacing a Key Switch on a Logitech Mechanical Keyboard

A subscriber from New York City sent in a Logitech G910 Orion Spectrum RGB Mechanical Gaming Keyboard with a loose “A” key cap and a damaged key switch. In this video, I test, disassemble and give it a good cleaning. Then I remove and replace the key switch with a used one from eBay. The key cap then gets replaced and the keyboard is reassembled.

This is the first RGB mechanical keyboard I’ve worked on, so I did a bit of Google research when trying to figure out how to fix it. Thankfully, there are replacement key switches and caps available on eBay. The other neat thing I found was the Mechanical Keyboard Subreddit. It has tons of useful information, as well as amazing examples of custom keyboards people have built. I’m only starting my mechanical keyboard journey, and I definitely have a lot to learn, so it’s nice to have quality information to reference.

We’re big fans of attempting a repair on a broken item to keep it out of the landfill. Thanks again to our generous subscriber who sent this in.

Here are some handy shortcuts:
Test the keyboard (0:45)
Disassembly (1:28)
Desolder the broken “A” and Scroll Lock (5:20)
Cleaning (7:00)
Solder the key switches back on to the board (9:19)
Reassemble the keyboard (10:28)

Here is a list of the sites and items we mentioned in the video:
Keyboard tester site
Mechanical Keyboard Subreddit
Nanch Small Precision Screwdriver 22 in 1 Tool Kit
Vastar Soldering Iron Kit 60W 110V
Non-marring Pry Tools (this set is similar to the one I used in the video)

After posting the video, I found a site that explains the differences between the blue and black key switches. The Deskthority page on Omron B3K series switches details the three types of mechanical switches used in the different models and vintages of Logitech mechanical keyboards. Omron released different variants of this switch for several companies; the Logitech-branded versions are labeled as Romer-G. Now I’ll know which one to order the next time I need one.

If you have questions, comments, or suggestions, please post them in the video comments on YouTube. Thanks!
