Clean your vintage IBM M2 clicky keyboard!

Step 4 Release the latches

Now it's nice to have an extra hand or two, or a partner to help. Use a DULL flatblade driver to lightly pry the side of the keyboard apart, while your partner pushes the latches open with a driver. After you get one or two latches separated the keyboard will keep itself open and it's pretty easy to release the rest of the latches. I started from the right side of the keyboard, and it worked fine.
