How to Replace a Type K21 Keyboard Key

This guide is for hinge type K21. This very popular hinge type is used in the following models:

Some colors in the pictures may differ for your model. That is fine, what matters most is the shape of the hinge piece.

Step 1: Orient the hinge

The plastic hinge mechanism must be oriented as shown for it to fit onto the metal keyboard hooks.

Step 2: Hook the hinge onto the base

Hook the top inner part of the hinge over the top two metal hooks on the base of the keyboard. Here we are using pliers but this can be done without tools.

Step 3: Secure the hinge into place

Snap the bottom of the hinge into place, by pressing down on the lower half of the hinge. The bottom right and left sides of the plastic hinge should be clipped between the two metal notches protruding from the base of the keyboard on each side. Check that the hinge works by flexing it up and down; it should pivot easily at its axis.

Step 4: Press the key into place

Align the key on top of its place on the keyboard, and press down evenly. All four corners of the key should click into place.

    Hi there I have lost the hooks that the bracket would go on – they are squashed in.
    Is there another way to put my key back on.
    Many thanks, Dave
