I Think My Switch Is Stuck! - The Tale of Cherry MX Locks
Over the years of collecting mechanical keyboard switches, I’ve been lucky enough to have encountered dozens upon dozens of rare and unique ones that have stuck in my mind to this day. Prototypes, factory errors, and even a few switches so rare that there is literally zero documentation about them anywhere in the world all fill that personal list from top to bottom. However, I realize that talking about switches so far outside of most people’s reaches, and even sometimes my own grasp, doesn’t make for the most exciting of articles about switches. To this newest generation of keyboard enthusiasts, though, there is one pretty rare MX-style switch which has made its way to the top of everyone’s “must try” lists – Cherry MX Locks. These often undiscussed and even more rarely seen switches are something that few people have seen and even fewer have had the chance to try at a meetup before. However, the list of people who really know how these unique Cherry switches work is even shorter...

I'm used to paying $350+ for custom aluminum keyboards, but was totally shocked when I received my $160 KDB75. The keyboard was packaged extremely well and arrived from China with no flaws, and weighted far more than I was expecting. It weighs more than my RS96. I never was really into the 75% layout, but I was never into the 96 key layout until I tried it, so I figured I'd give it a try since the price was definitely right.
But enough of the "review" part, lets get on to programming this guy. I always like to do guides because I know that being intimidated by programming a custom can often lead to people skipping buys they would otherwise join. This is a very easy one to program, so nothing to be afraid of here!
The first step is to simply download the Bootmapper client found here: https://www.dropbox.com/s/3bn9flirkb49ahz/BootMapperClient.zip?dl=0
After downloading it and running the .exe (I'm on Windows, there is an OSX version as well) you should see something like this:
Once this is active you will press the key you want to remap, and it should get highlighted in red within the matrix. Simply click on the key you want to change it to from the selection of keys at the bottom. It should look like this, using Caps Lock as an example:
One more very important thing to point out is lighting controls. You will probably want to put these on the normal FN layer. RGB mode controls the SMDs on the PCB for underglow, and LED mode, LED BrUp, LED BrDN only affect in switch LEDs. the LED on/off affects both.
Moving on to lighting!
To access the lighting features (both under PCB SMDs and in-switch LED's) go to Options from the main tab selection. You should see this screen:
Now lets head back to the main tab to flash the new layout to the keyboard. Make sure "ps2avrGB & ps2avrGB_split" is selected as the target:
