How to Repair Broken Computer Keyboard Keys

If you’ve ever had a computer keyboard key fail, you know how inconvenient it can be. Not only is it difficult to type when not all of the keys function, but it may also be difficult to locate someone who can repair it for you.

Repairing damaged keys on your computer keyboard may seem difficult, but it is a simple technique that requires no special equipment or expertise. You should be able to repair a damaged key on a laptop or keyboard by the conclusion of this tutorial.

Types of Keyboards and How to Fix Them

When it comes to repairing damaged keys on a keyboard, one of the most crucial factors to examine before beginning to identify the problem is the kind of switch the keyboard utilizes. In keyboards, the two most frequent kinds of switches are utilized. There are two types: membrane and mechanical.

Difference Between Membrane and Mechanical Switches for Keyboards

Membrane switches are most typically seen in low-cost keyboards. They are quieter and have a gentler feel than mechanical switches, but they are also less durable.

Mechanical switches, on the other hand, are the oldest switches utilized in high-end keyboards. They are well-known for their longevity and precision actuation, although they are also noisier than other kinds of switches.

Broken keys may be repaired in both membrane and mechanical keyboards. However, if the problem with the membrane keyboard is not mechanical (such as a broken keycap)—for example, if some liquids were spilled on it—you will need to replace the whole keyboard, as opposed to mechanical, which can be fixed separately.

Things You’ll Need to Fix Keyboard Keys

To repair the damaged key, remove it, clean it, and replace it. The following are the most helpful tools:

  • A small flathead screwdriver
  • Tweezers
  • Superglue
  • A replacement key

How to Fix Keyboard Keys With Broken Keycaps

A broken keycap is the most frequent sort of damage, and it can generally be repaired by simply replacing the damaged component. However, if the key is too deep or the plastic has cracked, you will need to replace the whole keyboard. The following sections cover how to repair keyboard keys with damaged keycaps.

How to Remove the Keycap From the Keyboard Switch

Follow the procedures below to carefully remove the damaged keycap from the keyboard:

  1. Check to see whether the key is really broken or just trapped. If it’s the latter, experiment with various postures and see what happens—this may enough for some folks. However, if it is broken, continue to remove it.
  2. Use tweezers to carefully apply pressure along the bottom edge of a broken keycap to remove it.
  3. If you don’t have tweezers, carefully pull up on one side of the keycap with a screwdriver. You may need to jiggle it a little to get it going.
  4. Lift the slack side. Then repeat the process with your other hand, raising it gently.
  5. You should be able to see some plastic plates after removing the keycaps. If they’re recalcitrant, gently pull on one side while pressing down with the other.

That’s all! You now understand how to take the keycap off any mechanical keyboard. Keep in mind that most laptops do not have user-replaceable keycaps, so with your manufacturer first.

How to Put a Key Back on a Keyboard

Now that you know how to remove a keycap, let’s go through how to replace it. It’s rather straightforward.

  1. To begin, align the keycap with the switch. On the bottom of the keycap, you’ll find little plastic or metal posts. These posts slide into the switch’s little holes. Check that the posts are aligned with the slots before gently pressing down on the keycap until it snaps into place. If you don’t have a keycap replacement kit, you may use superglue or epoxy to repair a damaged key.
  2. Use rubbing alcohol to clean the area surrounding the damaged key before applying superglue.
  3. Apply a little quantity of glue or epoxy on the replacement key’s plunger and push it firmly into place. Allow the glue or epoxy to cure for 24 hours before resuming use of the keyboard.
  4. Using a screwdriver, remove the screws on your keyboard and extract it from its casing. As you do this, take care not to harm the connections on the back of the keyboard.
  5. Once the old keyboard has been removed, you may begin installing the new one.

How to Replace the Entire Keyboard

Replacing the whole keyboard might be difficult since you’ll have to remove screws and pry open your laptop. So be cautious and take your time.

  1. Next, line your new keyboard’s connection with the casing and push down until they connect.
  2. Once they’re lined up, gently press down on the keyboard until it clicks into place. Then, replace all of the screws you removed before.
  3. Begin by gently wiping them down with a soft cloth.
  4. If this doesn’t work, try blasting away any dust and debris using a can of compressed air.

Once your keyboard has been replaced, be sure to test it before putting your computer away. Check that all of the keys operate correctly and that there are no loose screws. Once you’re pleased, you may reassemble your computer and enjoy your new keyboard!

  1. Make careful to keep the can upright when doing this, since doing so might harm the keys.

Fix Your Broken Keyboard With Ease

As you can see, there are numerous methods for attempting to repair damaged keys on a laptop or desktop keyboard. However, the measures you must do will differ depending on how it was damaged in the first place. If it’s dust, all you have to do is clean it up or blast compressed air at it.
