How to Fix Sticky Keys
When a laptop keyboard malfunctions, it makes typing difficult. Two of the most common
Keyboard issues are sticky keys or unresponsive keys.
To clean up sticky keys, you may use rubbing alcohol on them or blow dust between the keys
using compressed air. If it’s a software issue, toggle them off by pressing the “Shift” button five
times or any two keyboard keys simultaneously. If the issue still exists, check the laptop for
Drivers, turn off the “Sticky Keys” through settings, or verify loose contacts.
Sticky keys are caused by fluid spills or dust collecting underneath the keys, causing them to
become gummed up.
Method 1: Cleaning the Keyboard
Use rubbing alcohol or compressed air to get rid of sticky keys. Disconnect the keyboard from power.
Blow compressed air into the keyboard to remove dirt or dust from the spaces between
the keys and the keyboard base. Use a toothpick and scrape whatever you can out from between or below the keys. Use isopropyl alcohol sprayed onto a soft cloth and wipe the keys with it. Note: if your
computer is coated with a UV layer; do not use isopropyl alcohol since it will destroy the
layer. Use water instead. Press the keys repeatedly. If they aren’t sticky, your problem has been solved.
Method 2: Removing the Keys (If Cleaning Doesn’t Work)
If your keys still feel sticky despite cleaning, do the following: Photograph your keyboard so that you can remember how those keys are positioned on
it.
For these keys, use a keycap puller tool and then a screwdriver to pull them. Read your guidebook on your laptop to find out how to make this move. In the event
you have a MacBook; peel off the sticky keys using the top and work your way through
every key individually. After removing all the keys, blow compressed air through the keyboard to get rid of any
dirt exposed. Use a cotton swab soaked in alcohol and gently remove the stickiness. You may wash the keys if their undersides are dirty. Run water over them and let them
air dry on a paper towel. Place the keys back in their original position once they are completely dry. Refer to the
picture you took to place them in the correct order.
Method 3: Fixing Software Issues
Sometimes, sticky keys are set up in a way that allows a user to press multiple keys down
simultaneously to create a command. Deactivate it by pressing the “Shift” button on your
keyboard five times. Alternatively, try pressing any two keys simultaneously, such as ‘Ctrl + Alt.’
to turn it off.
If the problem persists, try the following:
For Windows 10 & 11: Open Settings via the Start menu. On Windows 11, go to Accessibility > Keyboard.
On Windows 10, navigate to Ease of Access > Keyboard. To disable it, hit the toggle next to Sticky Keys (Windows 11) or Use Sticky Keys
(Windows 10). Quick trick: Disable the shortcut from settings so you will not accidentally activate sticky
keys on existing Shift presses.
For Windows 7 & 8
Sticky keys can also be disabled by pressing the Shift button five times or pressing any two keys
simultaneously. Open the Control Panel via the search option on the Start menu. Go to Ease of Access on the Ease of Access Center. Click on “Make the keyboard easier
to use.”
Clear the checkbox next to Turn on Sticky Keys. Select Apply to save.
How to Fix Unresponsive Keys
Keys become unresponsive due to dirt or software issues, like a loose keyboard cable or
unresponsive drivers.
Use compressed air to blow dust between the keys. You may use rubbing alcohol to
wipe left to right on the keys. If the keys still remain non-responsive, gently remove them using a tool. Clean the individual keys with a damp cloth. Inspect the underlying surface and clean the dirt. Place the cleaned keys back in place carefully.
Method 2: Troubleshooting Laptop Software
If keys don’t function despite cleaning, there may be issues with the software.
Updating Drivers
Open the Device Manager via the search option on the Start menu.
Once opened, find the keyboard section.
Right-click the keyboard device and click “Update Driver.” If the issue persists, download the latest drivers from the laptop’s official website.
Checking Keyboard Settings
Search the Start menu for Control Panel. Click on “Ease of Access” and select “Change how your keyboard works.” Turn off “Filter Keys” plus “Sticky Keys.”
Method 3: Checking Hardware Issues
Sometimes the issue is due to the laptop’s hardware.
Checking the Keyboard Connection
Locate the cable connecting the keyboard to the motherboard. Ensure it’s firmly
attached. If it is not, unplug it and reinsert it. If the cable has damage that is easily visible, replacement would be necessary. Try rebooting the laptop and see if the keys begin to work after.
When to Seek Professional Help
If your laptop keyboard still refuses to work after you have tried both software and hardware
troubleshooting, you need to take that laptop to an expert who can evaluate it in detail.

a professional. Laptop repair experts have specialized tools to repair your laptop effectively.
