How to put Spacebar back on

The spacebar, the longest key on a keyboard, is an indispensable part of typing. Whether you’re composing an email, writing a report, or engaging in a heated online battle, the spacebar is crucial for seamless communication and gameplay. However, there are times when this essential key may pop off due to an accidental strike, cleaning, or repair attempt. If you find yourself in this predicament, fear not. This article will guide you through the steps of How to put Spacebar back on, ensuring you’re back to typing with ease in no time.

Understanding the Spacebar Mechanism

Before diving into the reattachment process, it’s important to understand the mechanics of a spacebar. Unlike regular keys, the spacebar typically has a metal or plastic bar (stabilizer) that runs beneath it. This stabilizer is crucial for providing the necessary support and ensuring that the keypress is registered evenly, no matter where you press the spacebar.

There are two common types of stabilizers you might encounter: Cherry MX (or similar mechanical) stabilizers and Costar stabilizers. Identifying uses is the first step in successfully reattaching your spacebar.

Tools You Might Need

  • A flat-head screwdriver or a keycap puller (optional)
  • Tweezers (for handling small parts)
  • A clean, soft cloth (for cleaning)

Step 1: Clean the Area

Before reattaching ensure that the area is clean. Use a soft cloth to gently remove any dust, crumbs, or debris from the keyboard and the spacebar keycap itself. This step is crucial for preventing any obstruction that could affect the functionality of the key.

Step 2: Identify Your Stabilizer Type

Take a close look at the spacebar and its corresponding slot on the keyboard to determine the type of stabilizer.

  • Cherry MX Stabilizers: These are directly attached to the keycap and move down into the keyboard when pressed. They are easier to deal with since the stabilizer mechanism is part of the keycap itself.
  • Costar Stabilizers: These involve a bar that clips into inserts on the spacebar keycap. They can be a bit more challenging to reattach because you have to align the stabilizer bar and the clips correctly.

Step 3: Align the Stabilizer

Depending on your stabilizer type, the approach will slightly differ.

  • For Cherry MX Stabilizers: Position the spacebar over its slot, ensuring the stabilizer stems are aligned with the holes on the keyboard. Once aligned, you can move on to the next step.
  • For Costar Stabilizers: You’ll need to insert the stabilizer bar into the inserts on the spacebar first. Use tweezers to carefully place the bar into the slots on the spacebar. Ensure that the bar is flat and correctly seated in the inserts.

Step 4: Reattach the Spacebar

Now, gently place the spacebar back into position over its slot. Start by aligning the bottom part first (closest to you), making sure the stabilizer is correctly placed. Then, gently press down on the top part of the spacebar (the part furthest from you) until you hear a click, indicating that the keycap is securely attached to the switch and stabilizer.

Step 5: Test the Spacebar

Once the spacebar is attached, it’s time to test it. Press the spacebar at various points (left, right, center) to ensure that it depresses evenly and registers the keypresses. If the spacebar feels wobbly or does not register a press at certain points, you may need to readjust the stabilizer or ensure that the spacebar is properly seated.

Troubleshooting Common Issues

  • Spacebar Feels Loose: This could indicate that the stabilizer was not correctly seated. Remove the spacebar and repeat the steps, paying extra attention to the stabilizer alignment.
  • Spacebar Not Registering Presses: Ensure that the spacebar is correctly and firmly attached to the switch. If using a Costar stabilizer, verify that the bar is correctly inserted into the keycap’s inserts.
  • Sticky or Stiff Spacebar: This might be due to debris or misalignment. Clean the area thoroughly and reattach the spacebar, ensuring everything is aligned properly.

Maintaining Your Keyboard

To prevent future issues, regularly clean your keyboard and avoid eating or drinking over it. If you need to remove keycaps for cleaning, do so gently and use the appropriate tools to avoid damaging the keys or stabilizers.


Reattaching might seem daunting at first, but with patience and a careful approach, it can be a straightforward task. Whether you’re dealing with a Cherry MX or Costar stabilizer, the key is to ensure that the stabilizer is correctly aligned and the spacebar is firmly attached. By following these steps, you’ll not only save yourself a trip to the repair shop but also gain a deeper understanding of your keyboard’s mechanics.
