Step-by-Step Guide to Fix Sticky MacBook Keys
Step 1: Power Off and Prepare Your MacBook
Before starting any cleaning, completely shut down your MacBook to avoid accidental damage.
- Click on the Apple logo () in the top-left corner of your screen.
- Select “Shut Down.”
- Disconnect any external devices like USB drives or chargers.
Important: Avoid using excessive liquid directly on the keyboard, as it can seep inside and damage internal components.
Step 2: Surface Cleaning Around Sticky Keys
- Dip a cotton swab (q-tip) in isopropyl alcohol (rubbing alcohol).
- Ensure the swab is damp, not dripping.
- Gently wipe around each sticky key to remove dirt, grease, and minor residue.
- You may need multiple q-tips, as they tend to collect dirt quickly.
Why use isopropyl alcohol?
- Dries quickly without leaving moisture.
- Effectively dissolves sticky residues.
- Safe for electronics when used in moderation.
Step 3: Remove Crumbs and Debris Under the Keys
- Use a toothpick to carefully scrape away crumbs, dust, or gunk stuck between the keys.
- For deeper cleaning, use compressed air to blow out dust particles.
- Hold the MacBook at an angle to allow debris to fall out.
Step 4: Test the Keys
- Try pressing the previously sticky keys.
- If they still feel stuck, continue to the next steps.
Step 5: Removing the Sticky Keys (For Deep Cleaning)
If surface cleaning doesn’t solve the problem, you’ll need to remove the affected keys.
- Use a spudger or plastic opening tool to gently pry up the sticky key.
- Insert the tool under one corner of the key and lift slightly.
- Use your fingers to carefully twist and remove the key from the keyboard.
Warning: Avoid using excessive force, as MacBook keys are delicate and can break easily.
Step 6: Fixing Key Carriers (If They Come Off)
Once the key is removed, you may notice small white plastic components underneath. These are called key carriers (scissor mechanisms).
- If they detach, carefully align them back in place.
- Look at the reference image below to position the two pieces correctly.
- Press them together until you hear a soft clicking sound.
Step 7: Soaking the Keys in Soapy Water
If the keys have sticky residue from spills, soaking them helps restore their function.
- Fill a cup with warm water and dish soap.
- Drop the removed keys into the cup and let them soak for 10 minutes.
- Swirl them around to help remove dirt.
This step removes sugary or greasy residue from spilled drinks like coffee, juice, or soda.
Step 8: Wipe the Keyboard With Alcohol
- While the keys are soaking, use a q-tip dipped in alcohol to wipe down the keyboard surface.
- Focus on the exposed area where the removed keys were sitting.
Step 9: Cleaning the Back of the Keys (Optional, But Recommended)
- Remove the keys from the soapy water and dry them completely using a paper towel.
- Dip a q-tip in rubbing alcohol and wipe the back of each key.
- Allow them to air-dry completely before reattaching.
Step 10: Reattaching the Keys
- Position the cleaned key over its original spot.
- Press firmly in the center until you hear a double-click sound.
- Move your finger side to side to ensure the key is securely in place.
