If your MacBook keyboard isn’t working, you’re not alone. From stuck keys to complete key failure, keyboard issues are one of the most common problems faced by MacBook users — especially those with the infamous butterfly keyboard design.
At Chunyilin, we’ve helped thousands of customers replace and repair faulty MacBook keyboards with OEM-quality parts and professional installation. This article will walk you through why your MacBook keyboard might fail and how to fix it — using a real case study from our repair center.
Case Study: MacBook Pro Keyboard Failure
Customer: Li Wei, Shanghai
Model: MacBook Pro 13" (2018) — Butterfly Keyboard
Problem: “E,” “T,” and spacebar keys unresponsive; random double typing
Impact: Urgent — essential for freelance design work
Step 1 — Identifying the Problem
Li Wei reported worsening typing issues over 3 months. Our diagnostic process revealed:
-
No signs of liquid damage
-
Several keys failing mechanical response
-
Faulty butterfly mechanism — a known issue in 2015–2019 MacBook models
Why MacBook Keyboards Stop Working
-
Dust & Debris – Tiny particles can block the ultra-thin key mechanism.
-
Liquid Spills – Even a few drops can short-circuit the keyboard membrane.
-
Butterfly Mechanism Issues – Apple’s low-travel design is prone to failure.
-
Cable Wear – The keyboard ribbon cable can weaken over time.
-
Aging Components – Frequent use wears down key responsiveness.
Step 2 — Choosing the Right Fix
For lasting results, we don’t recommend single key replacements for butterfly keyboards. Instead, we installed a full Chunyilin replacement keyboard:
-
OEM-Quality Build — Matches original size, layout, and backlight
-
Reinforced Mechanism — Longer lifespan than original butterfly design
-
Professional Installation — Avoiding palm rest warping and misalignment
Step 3 — Testing & Quality Control
After installation:
-
50-key continuous typing test — Passed
-
72-hour operational test — Passed
-
Customer feedback: "It feels better than new!"
