How to Fix Sticky and Unresponsive Laptop Keyboard Keys

Having a sticky or unresponsive keyboard key on your laptop can be extremely frustrating. It can make typing difficult and slow you down. Thankfully, there are several methods you can try to fix sticky and unresponsive keys before needing to replace the keyboard.

Causes of Sticky or Unresponsive Keys

There are a few common causes of sticky or unresponsive laptop keyboard keys:

  • Dirt, dust, crumbs, grease – Built up debris underneath the keys can interfere with the key mechanisms, causing them to stick or stop working properly.
  • Liquid spills/sticky residues – Sugary drinks and spills can leave a sticky residue as they dry, gumming up the key mechanisms.
  • Worn out keyboard – Over time and heavy use, the keyboard components can wear out, causing keys to fail.

Here are some step-by-step methods to try fixing sticky or unresponsive laptop keys:

1. Remove Debris and Dirt

  • Turn off and unplug your laptop.
  • Tilt your laptop keyboard-side down to let debris fall out. Gently shake it as well.
  • Use compressed air to spray out any remaining dust or crumbs stuck underneath the keys.

2. Clean with Isopropyl Alcohol

  • Dampen a cotton swab or microfiber cloth with isopropyl alcohol.
  • Gently wipe down each sticky keytop, as well as around the edges.
  • Let keys fully dry before turning laptop back on.

3. Pop Off Key and Clean Underneath

  • Use a small flathead screwdriver or plastic pry tool to gently pop up the sticky key.
  • Remove any dirt or debris buildup on key retainer clips and mechanism parts with cotton swabs and alcohol.
  • Press key firmly back into place after cleaning.

4. Update or Reinstall Keyboard Drivers
