Step 3

If the key is stuck, gently insert a spudger under the edge of the keycap.
Start from one corner and carefully pry the keycap from the keyboard, working your way around it until it pops out.
Inspect the key mechanism (scissor switch under the keycap) for any damage or debris.
If the keycap is dirty, clean it by soaking it in warm soapy water.
Ensure the key mechanism and cap are dry before reassembling.

Edit

Step 4

If the mechanism is damaged, you will need to replace it.
Install the new or previously removed key by aligning the keycap with the key mechanism. Align the top of the scissor-switch to the metal notches on the keyboard and then align the bottom of the switch, ensuring you hook the scissor-switch onto the metal tab on the keyboard.
Press down firmly on the keycap until it snaps into place.
