MacBook keyboard not working? Try these, in this order.
Eight fixes from fastest to slowest, how to tell software problems from hardware ones, what a keyboard repair actually costs — and the point where selling the broken Mac beats paying for the fix.
By Rick · Updated June 2026 · 6-minute read
A dead MacBook keyboard feels catastrophic, but most sudden failures are software — a glitch, a buried accessibility setting, an app capturing your keystrokes. Work down this list in order; each step is faster than the one Apple's support queue will eventually walk you through. And if you land at the bottom with a confirmed hardware failure, I'll give you the honest repair-vs-sell math instead of pretending every Mac is worth fixing.
First: the 30-second hardware test
Before anything else, plug in any external USB or Bluetooth keyboard (or use macOS's on-screen Keyboard Viewer: System Settings → Keyboard → Input Sources → show Keyboard Viewer).
- External keyboard works, built-in doesn't → almost certainly hardware: keyboard membrane, ribbon cable, or liquid damage. Skip to the repair-vs-sell section.
- Neither keyboard works → software. The fixes below will very likely get you typing again.
The 8 fixes, fastest first
| Fix | Time | What it fixes | How |
|---|---|---|---|
| 1. Restart the Mac | 1 min | Software glitches, stuck processes capturing keystrokes | Apple menu → Restart. Sounds dumb. Fixes a surprising number of “dead” keyboards. |
| 2. Check for crumbs / debris | 2 min | Single stuck or repeating keys | Hold the Mac at 75°, spray compressed air left-to-right across the keys. Apple's own official fix for butterfly keyboards. |
| 3. Turn off Slow Keys & Sticky Keys | 1 min | Keys that need a long press to register, or modifiers acting weird | System Settings → Accessibility → Keyboard. Both off. |
| 4. Disconnect USB devices & unpair Bluetooth keyboards | 1 min | Input being captured by another device | Unplug everything, toggle Bluetooth off, test the built-in keyboard alone. |
| 5. Update macOS | 15 min | Driver/firmware bugs after OS updates | System Settings → General → Software Update. Keyboard firmware ships inside macOS updates. |
| 6. Test in Safe Mode | 5 min | Third-party software conflicts (keyboard remappers, security tools) | Apple Silicon: shut down, hold the power button, pick the disk, hold Shift. Works in Safe Mode = software problem, not hardware. |
| 7. Create a new user account | 5 min | Corrupted per-user settings | If the keyboard works under a fresh account, the fix is in your account's settings, not the hardware. |
| 8. Reset SMC (Intel Macs only) | 2 min | Power-related keyboard/trackpad failures on pre-2020 Macs | Shut down, hold Shift+Control+Option (left side) + power for 10 seconds. Apple Silicon Macs have no SMC reset — a restart does the equivalent. |
Two details people miss: Slow Keys (step 3) makes a keyboard feel "mostly dead" because only long presses register — it gets switched on accidentally more often than you'd think. And the compressed air in step 2 is Apple's own published procedure: hold the MacBook at a 75° angle and spray the keyboard left-to-right, then rotate and repeat. It rescues stuck and repeating keys, especially on 2016–2019 butterfly keyboards.
What the failure pattern tells you
- One stuck or repeating key: debris. Compressed air, then a careful keycap clean.
- A cluster of dead keys: debris or early liquid damage to that section of the membrane.
- Whole keyboard + trackpad dead together: the shared ribbon cable or a power issue — on Intel Macs, try the SMC reset; on any Mac, this is a repair-shop diagnosis.
- Keys type wrong characters: input source / keyboard layout setting, not hardware. System Settings → Keyboard → Input Sources.
- Worked fine, died after an update: software. Safe Mode and the next macOS point release usually settle it.
- Died after a spill — even a small one: liquid damage. See below, and stop charging it now.
The butterfly keyboard problem (2015–2019 Macs)
If your Mac is a 2016–2019 MacBook Pro or a 2018–2019 Air, the keyboard itself is the design flaw — the butterfly mechanism fails from dust alone. Apple ran a free Keyboard Service Program, but it covered each machine for only 4 years after first sale, and every eligible model has aged out. Today that repair is out of pocket.
Here's the honest math on those machines: a top-case replacement runs $350–$600, and most butterfly-era Intel Macs resell for less than that working. Fixing the keyboard on one is putting new tires on a car worth less than the tires. Sell it as-is, put the cash toward an Apple Silicon Mac with the modern scissor keyboard, and the problem never comes back.
If liquid was involved
Shut it down and do not charge it or power it on for 48 hours — current flowing through wet circuits is what kills logic boards, and rice does nothing. Even if the keyboard recovers, corrosion keeps spreading for weeks; spill survivors often die a month later, and the liquid contact indicators inside have already voided the warranty either way.
A spill-damaged Mac still holds real parts value. We have a dedicated walkthrough for water-damaged MacBooks and liquid-damage trade-ins — get the quote before paying for a repair that may not hold.
Confirmed hardware failure: repair or sell?
Apple doesn't replace a MacBook keyboard by itself — it's riveted into the top case, so a "keyboard repair" is a top-case replacement that includes the battery and trackpad. Real-world out-of-warranty pricing:
- MacBook Air (Apple): roughly $250–$400
- MacBook Pro (Apple): roughly $350–$600
- Independent shops: usually 20–40% less, with shorter turnaround
The decision rule is one line: if the repair quote is more than half what your Mac sells for working, sell it broken instead. A dead keyboard doesn't touch the parts that carry the value — display, logic board, chassis — so broken-keyboard Macs trade for far more than people expect.
We buy them directly: MacBooks with broken keyboards, broken MacBooks of any kind, and Macs that won't turn on at all. Photos and model number get you a same-day number — that credit plus the repair money you didn't spend usually covers a refurbished replacement with a working keyboard and a fresh 1-year warranty.
Honest take: restart, compressed air, and the Slow Keys check fix most "dead" keyboards in under ten minutes — do those before you panic. But if the external-keyboard test points at hardware on an Intel-era Mac, don't sink a $400 top case into a $350 laptop. That's the trap. Sell it, upgrade to Apple Silicon, and type in peace.

Frequently Asked Questions
Why is my MacBook keyboard suddenly not working?
The most common causes, roughly in order: a software glitch (fixed by a restart), debris under the keys, an accessibility setting like Slow Keys silently enabled, a macOS update bug, a third-party app capturing keystrokes, or — the hardware causes — liquid damage, a failing keyboard ribbon cable, or a swollen battery pressing on the top case. Work through the software fixes first; they resolve the majority of sudden keyboard failures.
How much does it cost to fix a MacBook keyboard?
Apple doesn't replace individual keys or just the keyboard — the keyboard is riveted into the top case, so a keyboard repair is a top-case replacement that includes the battery and trackpad. Out of warranty that typically runs $250–$400 at Apple for MacBook Airs and $350–$600 for MacBook Pros. Independent shops are often 20–40% cheaper. On an older Mac, the repair frequently costs more than the machine is worth — get a trade-in quote on the broken Mac before paying.
Does Apple fix butterfly keyboards for free?
Apple's Keyboard Service Program covered 2015–2019 butterfly-keyboard MacBooks for 4 years after first retail sale — and every eligible model has now aged out of the program. If you have a 2016–2019 MacBook Pro or 2018–2019 Air with sticky or dead keys today, you're paying out of pocket. For most of these Intel-era machines, the top-case repair costs more than the Mac's resale value, which makes selling it for parts value the better move.
Some keys work but others don't — what does that mean?
A few dead keys in a cluster usually means debris under the keycaps or early liquid damage to that section of the keyboard membrane. Try compressed air at a 75-degree angle first. If a whole row or scattered keys are dead and air doesn't help, the keyboard membrane or ribbon cable is failing — that's a hardware repair. An external USB keyboard will confirm it: if the external works fine, the built-in keyboard hardware is the problem.
My keyboard stopped working after a spill — can it be saved?
Immediately: shut it down, unplug it, and do NOT charge it or turn it on for at least 48 hours. Rice doesn't work. Even if the keyboard comes back, liquid corrosion progresses for weeks — keyboards that survive a spill often die a month later, and the liquid contact indicators inside have already voided your warranty. A spill-damaged Mac still has real trade-in value (the screen, logic board, and chassis are worth money as parts), so get a quote before paying for a repair that may not hold.
Is a MacBook with a broken keyboard worth anything?
Yes. A dead keyboard doesn't touch the parts that hold most of a MacBook's value — the display, logic board, and chassis. An M1 MacBook Air with a dead keyboard still trades for a meaningful fraction of its working value, and even butterfly-era Intel Pros are worth real money as parts donors.
