One or more keys fell off the laptop keyboard and you are not sure how to put them back? Don’t worry, most likely you can fix the keyboard and it’s not necessary to buy a new one. There is no universal repair guide because all keyboards are different. Here’s what I usually do in this case.
Situation 1. The key cap and key retainer fell off the keyboard and you cannot figure out how to assemble them back.

Laptop key fell off

Replacement Laptop Key has the right Laptop Key Replacement for you.

Carefully remove the cap from any other working key so the key retainer stays connected to the keyboard.

Remove key cap

Take a closer look at the key retainer, it’s connected to the keyboard at four different points.

Assemble the key

Assemble the disconnected retainer the same way as one on the keyboard and put it back in place.

Install the key

Put the key cap on the retainer and snap the cap back in place.

Snap key cap

Situation 2. The key fell off the keyboard and you lost the cap or the retainer. In this case you can purchase a single key on the internet, just search for it. (Search examples: “Dell keyboard key”, “Toshiba keyboard key”, “HP keyboard key”, etc… )
After you found a new key, put it back in place the same way as I described in the situation 1.

Installing the space bar key.

The space bar key is connected to the keyboard a little bit differently then any other key.

Space bar key fell off

There is a metal retainer connected to the space bar key (on some keyboard models). Separate the retainer from the space bar key with a flat head screwdriver.

Remove metal retainer

Install the retainer back in place as it shown on the picture. You have to engage the retainer with the small hooks on the keyboard.

Connect retainer to keyboard

Put the space bar key back in place and gently press on it with fingers until it snaps back in place.

Connect space bar

That’s it. The space bar key is installed back in place and should work as before.

Here’s another technique you can use to fix a broken keyboard key.

As you see on the picture below the keyboard is missing the U key. The key cap, retainer and even silicone membrane were lost. Let’s see if it’s possible to temporarily fix the U key without buying any spare parts.

Personally, I cannot use keyboard without U key but I can live without a key located on the side from the right ALT – the “Right clicker” key. In the following guide I will remove one key I never use and install it in the place of missing U.

Keyboard missing one key

Carefully remove the key cap with your fingers.

Remove key cap

Remove the retainer. The retainer has two pieces connected to each other. If one piece got disconnected from the other, connect them back together.

Remove key retainer

The silicon membrane is glued to the keyboard. Very very slowly separate the membrane from the keyboard with a sharp knife. While creating this disassembly guide I damaged one membrane because I wasn’t careful enough.
Again, you have to be very careful removing the membrane.
If you damage the membrane you’ll end up with two broken keys instead of just one.

Key membrane

The silicon membrane has been removed.

Key membrane removed

Now apply some superglue on the bottom edge of the membrane, just enough to keep the membrane in the place.

Apply super glue

Carefully place the membrane in the center of the U. Make sure the membrane is positioned correctly. Wait until the glue cures.

Install key membrane

Install the retainer.

Install key retainer

Position the key cap above the retainer. Gently press on the key cap until it clips in and connects to the retainer.

Position key cap

Now you can use the U key again.

Keyboard is fixed

Troubleshooting. Why the key will not clip on.


Turn the key upside down and take a closer look at the locking clips. It’s possible that one of the clips is damaged and because of that the key will not clip on the retainer. If that’s the case, you’ll have to purchase a new key.

On the next picture you can see that one of the clips is missing, it’s broken. This key will not stay connected to the retainer either. If that’s the case, you’ll have to purchase a new key.

It’s possible that the key is fine, but the retainer itself is broken. On the next picture you can see that one of the tips is missing on the retainer. The left tip is OK, but the right one is missing. If that’s the case, you’ll have to purchase a new retainer.

Here’s one more picture. In this case two parts of the retainer will not stay connected to each other. It happens because one of the tips is broken. The left tip is OK, but the right one is missing. If that’s the case, you’ll have to purchase a new retainer.

    THANK you SOOO much! My N key had stopped functioning (junk underneath), and I knew the right answer was to pop off the key (our cockatiel does it, why can’t I?), clean underneath. Only the key retainer came, too, and without your ace photos and instructions I never would have had the nerve. I popped off the B key and this time only the cap came off, and I could inspect the other retainer. Managed to wiggle it in there with the help of a plastic Bic pen top. Everything works perfectly now!

    Thanks! The backspace key, with the retainer attached, came off and I couldn’t get it back on. Your pictures showed me that it was actually two pieces, key and retainer, and that the retainer needed to be on the laptop first. I then got the retainer off the key, easily got it back on the laptop, and then snapped the key into place! So simple when you have a little help from someone who knows! Thanks for sharing your knowledge.

    Then why are you looking for instructions on the Internet. Just buy a new keyboard and replace it smart ass.
    And stop eating when you work on the laptop, it will help. Good luck!
    By the way, read previous 170 comments. These instructions worked great for many people.

    Horrible instructions. “Take another key off to see how it’s done, and follow suit?” Thanks a lot, I never would have thought of that myself [sarcasm]. Consider this situation:

    My key is sticky, so I popped it off to clean underneath it, and now I can’t get it back on. The LAST thing I want to do is to ruin another key by taking it off.
