Gather your repair equipment. In order to attempt to repair a key on your laptop's keyboard, you'll need the following items:
- Prying item - Something plastic, such as a credit card or a spudger, is best; you can use a butter knife or a flathead screwdriver in a pinch.
- Q-tip - Used to clean grit and dust from the area surrounding the key.
- Toothpick - Used to clean grooves around the key.
- Tweezers - Used to pull away pieces of the key carriage. Not necessary for all computers, but helpful.
- A container - Used to store the pieces of the key while you make the repairs. You can use a bowl, a plastic bag, or any similar such item here.

Know the anatomy of a key. Most keyboard keys are comprised of three parts: the key cap (which is the key itself), the key carriage (a flat piece of plastic on which the key sits), and the key pad (a piece of rubber that sits between the key and the carriage).
- Most MacBook keys don't have the rubber key pad.
- Many computers' key carriages are comprised of two or more pieces of plastic that nest together.

It's best to find a flat, clean, indoor area, such as a kitchen table or a counter, on which to perform your repairs.

Turn off and unplug your computer. Make sure that your computer is off and not plugged into a power source when your go to remove a key.
- You may want to remove the computer's battery as well, if possible.
Ground yourself before attempting any repairs. While the chances of you damaging your computer's internals with static electricity via a key repair are slim, grounding only takes a second and is good practice for dealing with electronics in general.

Clean the area around the key. Using a damp q-tip, swab the area between the key that you want to replace and the surrounding keys. This will usually constitute moving the q-tip in a square around the key.
- If your keyboard is sticky or grimy, you can use a small amount of isopropyl alcohol on the q-tip to help remove the grime.
Use the toothpick to scrape gently the space below and around the key. This will help prevent any loose dust or grit from falling down into the key's slot.
Pry up the bottom of the key at a 45-degree angle, then pull it away from the keyboard and set it somewhere safe.^{[1]XResearch source}

You can usually remove, clean, and restore unresponsive keys. A lot of the time, the key is just dirty and needs proper cleaning to work again. If that doesn't work, you might need a full keyboard replacement.

Review the carriage for bent or out-of-place parts. If the carriage isn't laying flat or it appears to be warped, try gently pressing down on the bent part to see if it will snap back into place.^{[2]XResearch source}
- Likewise, if the key cap is tilted or loose, try pressing down on it to see if it snaps back into place.
5
Remove the key's internal parts. This includes the carriage and key pad.
- Be sure to note the position of the internal parts so that you can place them back later.
One of the most common reasons for computer keys failing to work is foreign material in the area beneath the key. If you see any dust or residue, remove it and clean the area.
Place both the carriage and pad back in the key slot in the way in which they were initially set. You may have to press down on parts of the carriage to lock it into place.^{[3]XResearch source}
8
Place the key back in its slot. Insert the top of the key into the slot at a 45-degree angle, then lower the rest of the key into the slot. This should allow the hooks that are typically at the top of the key to catch when placed.^{[4]XResearch source}
- If there aren't hooks at the top of the key, this will still allow the key to come to a naturally horizontal resting position when you lay it down.
9
Press down firmly on the key. This will snap the key back into place. It should spring back up immediately after you remove your finger.^{[5]XResearch source}
- If the key is still broken (e.g., it won't spring back up, its letters don't type, etc.), you'll need to replace the key instead.

Snap the key pad into place. Push the key pad into the center of the carriage, then press down until it clicks or snaps into the carriage.

Question
I successfully reattached the key, but now it doesn't register on the screen when it's pressed, although it feels 'right' to the touch. What do l need to do?
Community Answer
First, take the key - you should see a small white button underneath. Press it. If it doesn't respond, you need a new key. If it does work, make sure the key is perfectly aligned with the button.

Warnings

If your key still won't work after being replaced, your keyboard's circuit board is most likely the problem. Having a laptop circuit board replaced is generally a task best left to a tech department (e.g., the Apple Store or a place like Best Buy).
