Step 2
Keycap Removal
- Take a photo of the keyboard to use as reference for the keyboard layout.
- Place your keyboard on top of a flat and clean table to prevent parts from going missing.
- Remove the keycaps by hand or with a key cap puller if one is available to you.

Step 3
Screw Removal
- Locate and remove the five screws mounting the keyboard onto the keyboard case.
- Secure the screws in a container for later use.

Step 4
Removing keyboard plate
- With the screwdriver, carefully pry the keyboard plate out of the case from the spacebar gap located at the bottom of the plate.
- This will require some force to pry open.

Step 6
Safety Precautions
- Make sure your workspace is well ventilated.
- Set up a portable fan or a fume extractor nearby.

Step 7
Desoldering Parameters
- For desoldering, set the solder station to 400℃.
- Allow the soldering iron enough time to completely heat up.
For desoldering, set the solder station to 400℃.
Allow the soldering iron enough time to completely heat up.
Step 8
Desoldering
- Using the labels on the back of the PCB locate your faulty switch.
- Begin desoldering by carefully applying the hot iron onto the two solder joints surrounding the key label.
- Use the solder pump when the solder visibly melts. Continue this process until the switch pins are visibly unsoldered from the PCB.
- Warning: Do Not Breathe in the soldering fumes.
- Warning: Do Not Touch the hot tip of the soldering iron.

Step 9
Removing the Faulty Switch
- After the switch is visibly de-soldered, carefully remove the faulty switch with a key switch puller.
- Note: This may be difficult to do by hand.

Step 10
Inserting the replacement switch
- With the replacement switch, line up the key switch pins with the corresponding holes on the PCB.
- Carefully insert the switch into the PCB, making sure to avoid bending the switch pins.

Step 11
Soldering Parameters
- Decrease the heat on the solder station to 350℃ and allow it to cool.
- Using a lower heat when soldering the switch back on is recommended to avoid over-soldering the switch joint.

Step 12
Resoldering
- Resolder the switchback onto the PCB by carefully heating the metal rings with the soldering iron, and then applying the solder wire onto the heated surface, keeping the iron in place.
- Apply solder to the switch pin until a small mound conceals the pin, resembling the factory solder job on the board. Allow the solder to cool and solidify.
- Try to be conservative with the amount of solder that is used. Less is more!
