Fix Delete Key Not Working on Your Keyboard (Windows + Mac)

If your Delete key isn’t working, you’re not alone. Sometimes it does nothing. Sometimes it only works in certain apps. Sometimes it triggers weird behavior (like opening something or acting like another key).

The good news: most “Delete key not working” problems are caused by simple things like a laptop Fn layer, an accessibility setting (Sticky/Filter Keys), a driver hiccup, or a dirty/stuck key.

This guide starts with the fastest, lowest-risk fixes first, then moves to deeper fixes, then last resort options.

1-Minute Fix (Try This First)

Do these in order:

  1. Restart your computer
  • Windows: Start menu → Power → Restart
  • Mac: Apple menu → Restart
    ✅ Test the Delete key again.
  1. Test Delete somewhere else
  • Try in a simple text box:
    • Windows: Notepad (or a browser search box)
    • Mac: TextEdit (or a browser search box)
      ✅ Test the Delete key again.
  1. If it’s a laptop, try the Fn-layer Delete
    Many laptops share Delete with another key.
  • Try Fn + Delete
  • If your keyboard doesn’t have a Delete key, try Fn + Backspace
    ✅ Test the Delete key again.
  1. Turn off Sticky Keys / Filter Keys (Windows)
    These can change how keys behave.
  • Go to Settings → Accessibility → Keyboard (wording may vary)
  • Turn Sticky Keys OFF
  • Turn Filter Keys OFF
    ✅ Test the Delete key again.
  1. Use the On-Screen Keyboard (quick workaround + test)
  • Windows: Search On-Screen Keyboard
  • Mac: You can enable Keyboard Viewer (System Settings → Keyboard, wording may vary)
    If Delete works on-screen, your physical key may be the issue.
    ✅ Test the Delete key again.

If it still doesn’t work, go to the step-by-step fixes below.

Quick Workarounds (So you can keep working)

Use these to delete text immediately while you troubleshoot:

  1. Backspace vs Delete (simple difference)
  • Backspace deletes the character to the left of the cursor.
  • Delete deletes the character to the right of the cursor (often called “forward delete” on some systems).
    ✅ Test the Delete key again.
  1. Select text, then delete it
  • Highlight text with your mouse/trackpad, then press Backspace (or Delete).
    ✅ Test the Delete key again.
  1. Cut as a workaround
  • Highlight text → press:
    • Windows: Ctrl + X
    • Mac: Command + X
      ✅ Test the Delete key again.
  1. Use an on-screen keyboard
  • Click the on-screen Del / Delete key.
    ✅ Test the Delete key again.
  1. Use an external keyboard (USB/Bluetooth)
  • If Delete works on the external keyboard, your laptop/keyboard hardware is likely the issue.
    ✅ Test the Delete key again.

Before You Fix Anything: Identify Your Situation (30 seconds)

Pick the path that matches you:

A) Laptop keyboard issue

  • Delete only works with Fn
  • Key feels sticky, doesn’t “click” right, or you recently spilled something
  • On-screen Delete works, but the physical key doesn’t

B) Desktop keyboard issue

  • External keyboard connected by USB
  • Delete stopped after moving USB ports / using a USB hub
  • Works on another keyboard but not this one

C) Software/settings issue

  • Delete works in some places but not others
  • Only broken in one program (Word, Excel, a game, a browser, etc.)
  • It triggers strange shortcuts

Now use the fixes below (in order).

Main Fixes (Easiest → Hardest)

A) Easy fixes (2–5 minutes)

A1) Restart your computer

What this helps: quick reset for stuck processes, drivers, and input glitches.
Steps:

  1. Restart (not shutdown) your computer.
  2. After it reboots, open a simple text box.
    ✅ Test the Delete key again.

A2) Test Delete in another app (Notepad/TextEdit)

What this helps: confirms whether it’s an app problem or system-wide.
Steps:

  1. Open Notepad (Windows) or TextEdit (Mac).
  2. Type a few words.
  3. Move the cursor into the middle of the text and try Delete.
    ✅ Test the Delete key again.

A3) Check laptop Fn / “Del” sharing (common on compact keyboards)

What this helps: many laptops require Fn to access Delete.
Steps:

  1. Look closely for Del printed on another key (often near Backspace or in the top-right area).
  2. Try Fn + (that key).
  3. If your keyboard has both Backspace and a Delete function, try Fn + Backspace too.
    ✅ Test the Delete key again.

A4) Check keyboard language/layout (if Delete behaves strangely)

What this helps: a mismatched layout can cause unexpected key behavior in some apps.
Windows steps (wording may vary):

  1. Open Settings.
  2. Go to Time & Language → Language & region.
  3. Check your Keyboard / input method matches your physical keyboard.
    ✅ Test the Delete key again.

Mac steps (wording may vary):

  1. Open System Settings.
  2. Go to Keyboard → Input Sources.
  3. Confirm the selected input source matches your keyboard.
    ✅ Test the Delete key again.

B) Windows fixes (beginner-safe)

B1) Turn off Sticky Keys

What this helps: Sticky Keys can change how keys and shortcuts behave.
Steps (wording may vary):

  1. Open Settings.
  2. Go to Accessibility → Keyboard.
  3. Turn Sticky Keys Off.
    ✅ Test the Delete key again.

B2) Turn off Filter Keys

What this helps: Filter Keys can ignore repeated/held keystrokes.
Steps (wording may vary):

  1. Open Settings.
  2. Go to Accessibility → Keyboard.
  3. Turn Filter Keys Off.
    ✅ Test the Delete key again.

B3) Run the built-in keyboard troubleshooter

What this helps: Windows can detect basic keyboard/input issues.
Windows 11 (typical path, wording may vary):

  1. Settings → System → Troubleshoot → Other troubleshooters
  2. Find Keyboard → click Run
    ✅ Test the Delete key again.

Windows 10 (typical path, wording may vary):

  1. Settings → Update & Security → Troubleshoot
  2. Look for Additional troubleshooters (or similar)
  3. Run Keyboard troubleshooter if you see it
    ✅ Test the Delete key again.

B4) Reinstall/update keyboard driver (Device Manager)

What this helps: fixes driver corruption or conflicts.
Steps:

  1. Right-click Start → open Device Manager.
  2. Expand Keyboards.
  3. Right-click your keyboard device (often “HID Keyboard Device”) → choose Uninstall device.
    • If you see a checkbox like “Delete the driver software,” leave it unchecked unless you know what you’re doing.
  4. Restart your PC (Windows will reinstall the driver automatically).
    ✅ Test the Delete key again.

B5) Try a different USB port / remove USB hub

What this helps: fixes power/connection issues, especially on desktops.
Steps:

  1. Unplug the keyboard.
  2. Plug it directly into a different USB port (preferably a port on the computer itself, not a hub).
  3. Wait a few seconds and test again.
    ✅ Test the Delete key again.

C) Mac fixes (beginner-safe)

C1) Confirm what “Delete” means on Mac

What this helps: avoids confusion—on many Macs, the key labeled Delete behaves like Backspace (it deletes left).
Steps:

  1. In TextEdit, type: ABCDE
  2. Click between C and D.
  3. Press Delete and see what it removes.
    ✅ Test the Delete key again.

C2) How to do “Forward Delete” on Mac (delete to the right)

What this helps: many Mac users think Delete is “forward delete” but it isn’t.
Try these (depends on Mac model/keyboard):

  1. Fn + Delete (common on MacBooks)
  2. If you use an extended keyboard, you may have a dedicated forward-delete key.
    ✅ Test the Delete key again.

C3) Check Modifier Keys / keyboard settings

What this helps: if a key is being remapped (or a custom layout is active), behavior can change.
Steps (wording may vary):

  1. Open System Settings.
  2. Go to Keyboard.
  3. Look for Modifier Keys (or similar).
  4. If you’ve changed mappings before, set them back to default.
    ✅ Test the Delete key again.

C4) Restart in Safe Mode (optional, only if you’re comfortable)

What this helps: Safe Mode loads fewer items, which can reveal if software is causing the problem.
Important: Steps differ by Mac type.

  • Apple silicon (M1/M2/M3):
    1. Shut down.
    2. Hold the power button until you see startup options.
    3. Select your disk, then hold Shift and choose Continue in Safe Mode (wording may vary).
  • Intel Macs:
    1. Shut down.
    2. Turn on and immediately hold Shift until you see the login screen.

In Safe Mode, open TextEdit and try Delete.
✅ Test the Delete key again.

If Safe Mode fixes it, something running in normal mode is likely interfering.

D) Hardware checks (for all devices)

D1) Test with another keyboard (separates hardware vs software)

What this helps: quickly tells you where the problem is.
Steps:

  1. Connect another keyboard (USB/Bluetooth).
  2. Test Delete in a simple text box.
    ✅ Test the Delete key again.

D2) Clean the key safely (power off first)

What this helps: fixes stuck keys caused by dust/crumbs.
Steps:

  1. Power off the computer (and unplug external keyboards).
  2. Turn the keyboard upside down and gently tap to dislodge debris.
  3. Use compressed air in short bursts around the Delete key.
  4. Wipe the key area with a dry microfiber cloth.
    ✅ Test the Delete key again.

D3) Check for physical damage / liquid spill symptoms

What this helps: identifies problems that cleaning/software won’t fix.
Signs:

  • Key feels mushy, sticky, or inconsistent
  • Multiple keys near Delete act weird
  • Problem started after a spill or heavy dust exposure
    ✅ Test the Delete key again.

D4) Use an external keyboard as a reliable workaround

What this helps: keeps you productive even if the built-in keyboard is failing.
Steps:

  1. Plug in a USB keyboard or pair a Bluetooth keyboard.
  2. Keep using it while you decide on repair/replacement.
    ✅ Test the Delete key again.

E) Deeper but still safe

E1) Malware scan (Windows Security)

What this helps: removes software that can interfere with input/shortcuts.
Steps:

  1. Open Windows Security (search it from Start).
  2. Go to Virus & threat protection.
  3. Run a Quick scan first.
  4. If problems continue, run a Full scan (takes longer).
    ✅ Test the Delete key again.

E2) Create a new user profile and test

What this helps: checks if your user settings are corrupted.

Windows (basic idea; wording may vary):

  1. Settings → Accounts
  2. Look for Family & other users (or similar).
  3. Create a new local user, sign into it, then test Delete.
    ✅ Test the Delete key again.

Mac (basic idea; wording may vary):

  1. System Settings → Users & Groups
  2. Add a new user, log into it, then test Delete.
    ✅ Test the Delete key again.

If Delete works in the new profile, the issue is likely settings/software in your main profile.

E3) Boot into another environment to test (optional)

If you’re comfortable: testing the keyboard in a different environment (like a different computer, or a temporary boot option) can confirm hardware vs software—but this can get complicated fast. If you’re not sure, skip this and go to Last Resort.
✅ Test the Delete key again.

F) Last resort

F1) Visit a technician / repair shop

Best if:

  • You suspect liquid damage
  • Multiple keys are failing
  • Cleaning + external keyboard tests point to hardware failure
    ✅ Test the Delete key again (after repair).

F2) Replace the keyboard (often simplest for external keyboards)

If it’s a cheap USB keyboard, replacement is usually faster and cheaper than repair.

F3) Laptop keyboard replacement may be needed

If the built-in keyboard is failing, a technician can replace the keyboard module (varies by laptop model). Using an external keyboard is a safe temporary solution.

Common Causes (Quick List)

  • Sticky Keys / Filter Keys changing input behavior
  • Driver issues (Windows)
  • Dust/debris causing a stuck key
  • Laptop Fn-layer (Delete is shared with another key)
  • App-specific shortcuts/conflicts (only fails in one program)
  • Hardware wear or liquid damage

Troubleshooting (Quick Answers)

  • “Delete works in some apps but not in Word/Excel.”
    Try Delete in Notepad/TextEdit first. If it’s app-only, look for app shortcuts/add-ins or settings that change key behavior.
    ✅ Test the Delete key again.
  • “Delete key types a character / opens something.”
    Check for:
    • Fn mode/Fn lock on your laptop
    • Keyboard remapping software (gaming keyboard tools, macro tools)
    • Wrong keyboard layout/input source
      ✅ Test the Delete key again.
  • “Backspace works but Delete doesn’t.”
    You may be missing forward delete:
    • Windows: Delete should remove to the right
    • Mac: try Fn + Delete for forward delete
      ✅ Test the Delete key again.
  • “My laptop has no Delete key.”
    Use Fn + Backspace or Fn + (key labeled Del).
    ✅ Test the Delete key again.
  • “Delete key only works with Fn.”
    That’s normal on many compact keyboards. If you want it without Fn, check if your laptop has an Fn-lock option (varies by model).
    ✅ Test the Delete key again.
