Removing the controller
In the case that you want to remove your controller if it is broken for example or you want to replace it with a different controller in the future.
To remove the controller you will need a spudger, guitar pick, plastic screwdriver, your fingernail or something similar. You will want something which is not conductive or sharp to not damage the controller.

You'll need your keyboard with its controller, and something to pry the controller off with, which can be your fingernail.
Using your non conductive tool pry up from the middle of the keyboard. The controller should pop off easily.

Place the tool between the keyboard and the controller from the side.

Lift the tool up to pop the controller off of the keyboard.
You have successfully removed the controller!

The controller is now separated from the keyboard.

Serial numbers on the keyboard.
Installing the controller
To install the controller you will need the controller and the keyboard. All it takes is a click.

The controller and the keyboard.
Align the controller with the connectors on the keyboards. The buttons should be facing the north side. You can also notice that from the bottom view, the top connector is smaller than the bottom connector - the controller will only fit in one orientation. You can't go wrong!

Aligning the controller.
Place the controller on top of the connectors of the keyboard.

Positioning the controller.
Press down in the middle of the controller until you hear it click. You may hear two clicks if one of the connectors snaps in place before the other. These clicks might not be loud. We'll check whether the connectors mated correctly in the next step.

Pushing down on the controller.
You can confirm if the controller is placed correctly by looking at it from the side. The connectors should be fully inserted. The controller will be oriented parallel to the keyboard, with an even distance to the keyboard all along its edge.

Confirming the placement.
This is how it's not supposed to look like. Notice how there is some space between the controller connector and the keyboard PCB. You'll see the controller sitting at a bit of an angle: this means one of the connectors isn't seated fully. Press a litle harder on the connector to get the connector to snap in place.

If the controller sits slanted, you'll have to push a little harder.
