Remove the screws

On the bottom of your keyboard, there are 4 screw holes as marked on the image.
You will need a 5.5 mm nut driver to remove these screws. This kind of driver can be found in the iFixit Mako Screwdriver kit, which is part of every Pro Tech Toolkit.
Turn the screws counter-clockwise to loosen them.
As you can see, my keyboard lacks the typical IBM birth certificate on the back of the keyboard. This is because I've replaced the original case of my keyboard with an industrial gray one. I left the sticker on the original case, so I can restore it's original state anytime I want.
In reality, the screw is 7/32" sized, but it is pretty uncommon size in Europe, and 5.5 mm is the closest metric tool to it. This size fits perfectly, and there is no risk stripping the screw head, using the metric tool.
