📋 Difficulty & Time

🔧 Fix Stuck or Unresponsive Keys: Step by Step

⚠️ Common Mistakes to Avoid

• Prying the key off (Apple's scissor mechanism breaks easily — you're now buying a $349 keyboard)
• Spraying alcohol UNDER the keys (can short the keyboard if it pools)
• Skipping the gravity test (most stuck keys release with just upside-down + air)
• Continuing to use after a liquid spill (causes corrosion of contacts)

🛠️ Fix 1: Restart Your Mac

Start with the basics:

1. Click Apple menu → Restart
2. If keyboard is completely dead, hold power button for 10 seconds to force shutdown
3. Wait 30 seconds, then power on
4. Test keyboard immediately after restart

🛠️ Fix 2: Check for Software Issues

1. Go to System Settings → Keyboard
2. Check "Key repeat rate" isn't set to Off
3. Check "Delay until repeat" settings
4. Disable "Slow Keys" if enabled (Accessibility → Keyboard)
5. Try creating a new user account and test keyboard there

🛠️ Fix 3: Reset SMC (Intel Macs)

For Intel-based MacBook Pro:

1. Shut down your Mac
2. Press and hold Shift + Control + Option on the left side + Power button for 10 seconds
3. Release all keys
4. Press power button to turn on

For Apple Silicon Macs: Simply shut down, wait 30 seconds, and restart. SMC is managed automatically.

🛠️ Fix 4: Reset NVRAM/PRAM

For Intel Macs:

1. Shut down your Mac
2. Turn on and immediately hold Option + Command + P + R
3. Hold for 20 seconds (you may hear startup sound twice)
4. Release and let Mac boot normally

Apple Silicon: NVRAM resets automatically on restart when needed.

🛠️ Fix 5: Boot to Safe Mode

Tests if third-party software is causing issues:

1. Intel Mac: Restart, hold Shift until login window
2. Apple Silicon: Shut down → Hold power until "Loading options" → Select startup disk → Hold Shift → Click "Continue in Safe Mode"
3. Test keyboard in Safe Mode
4. If keyboard works, a third-party app may be the culprit

🛠️ Fix 6: Clean the Keyboard

Debris under keys is a common cause, especially on butterfly keyboards:

1. Turn off your Mac and unplug it
2. Hold Mac at 75° angle (almost vertical)
3. Use compressed air in a zigzag pattern across the keyboard
4. Rotate Mac and repeat from different angles
5. For sticky keys: lightly dampen a microfiber cloth with isopropyl alcohol (70%+)
6. Gently clean around affected keys

🛠️ Fix 7: Check for Liquid Damage

Signs of liquid damage:

• Sticky or mushy keys
• Keys that don't register at all
• Corrosion visible under keycaps
• Random keyboard behavior

If liquid damage:

1. Immediately power off and unplug
2. Turn upside down to drain
3. Do NOT use a hair dryer (can push liquid deeper)
4. Let dry for 48-72 hours
5. Professional cleaning is recommended

🛠️ Fix 8: Test with External Keyboard

1. Connect a USB or Bluetooth keyboard
2. If external keyboard works perfectly, internal keyboard hardware may be damaged
3. This also helps you navigate while troubleshooting
