Understanding MacBook Keyboard Types
MacBook keyboards have evolved significantly over the years. Understanding which type you have is crucial for troubleshooting:
Butterfly Keyboard (2015-2019): Ultra-thin design but prone to dust and debris issues. Found in MacBook Pro 2016-2019 and MacBook Air 2018-2019.
Magic Keyboard (2020-present): More robust scissor mechanism with better key travel and reliability. Standard on all current MacBooks.
Common Causes of Stuck Keys
1. Dust and Debris: The most common cause, especially for Butterfly keyboards. Even tiny particles can prevent keys from functioning properly.
2. Liquid Damage: Spills can cause keys to stick or stop working entirely. The damage may not be immediately apparent.
3. Mechanical Failure: Key mechanisms can wear out or break, particularly the delicate clips on Butterfly keyboards.
4. Software Issues: Rarely, keyboard problems can be software-related, especially after system updates.
DIY Solutions to Try First
For Light Contamination:
- Use compressed air at an angle (not directly down)
- Hold your MacBook at 75 degrees and spray in a zig-zag pattern
- Tap around the affected key gently
WARNING: Never attempt to remove keys yourself, especially on Butterfly keyboards. The clips are extremely fragile and will break.
Professional Repair Solutions
When DIY methods fail, professional repair is necessary:
- Keyboard Cleaning: Professional ultrasonic cleaning can resolve many issues
- Individual Key Repair: We can replace specific key mechanisms
- Keyboard Replacement: For extensive damage, we replace only the keyboard (not the entire top case)
Our approach saves you money compared to Apple's solution of replacing the entire top case assembly.
Prevention Tips
- Use a keyboard cover for Butterfly keyboards
- Keep food and drinks away from your MacBook
- Clean your keyboard regularly with appropriate tools
- Consider AppleCare+ for Butterfly keyboard models
