MacBook Keyboard Not Working?
Few things are more frustrating than a MacBook keyboard that has decided to stop cooperating. Maybe one key does not work. Maybe a key types the wrong character. Maybe the whole keyboard is frozen. Maybe keys are physically stuck or make weird noises. MacBook keyboard issues range from easy software fixes to expensive hardware repairs, and which one you are dealing with depends on the model and symptoms. Here is how we diagnose and fix MacBook keyboard problems at Indiana Phones.
First: the notorious butterfly keyboard era
From 2015 to 2019, Apple used a ‘butterfly’ keyboard mechanism on MacBook Air, MacBook Pro 13-inch, and MacBook Pro 15-inch models. This keyboard design had a well-documented reliability problem — dust and debris could cause keys to stick, type twice, or stop working entirely. Apple ran a free keyboard replacement program for affected models (Apple’s Keyboard Service Program) but it has expired. If you have a butterfly-keyboard MacBook with failing keys, unfortunately the service program is no longer available. However, independent shops like Indiana Phones can still replace the keyboard (though it requires replacing the whole top case on these models, which is expensive). Post-2019 MacBooks use the improved scissor-switch keyboard which has been far more reliable.
Clean the keyboard first
Dust, crumbs, hair, and pet fur get into keyboards over time and can cause keys to feel sticky, type intermittently, or stop working entirely. Shut down the MacBook. Hold it at a 75-degree angle (almost upright). Use compressed air to blow across the keys in a sweeping motion — left to right, top to bottom. Rotate and repeat. This often dislodges debris and revives stuck keys. For butterfly-era MacBooks, this can sometimes fix intermittent issues.
Restart and check for software glitches
Shut down the MacBook completely (Apple menu > Shut Down, not just close the lid). Wait 30 seconds. Power it back on. Test the keyboard in TextEdit or any app. If specific keys work now, it was a software glitch. If the same keys are still broken, it is hardware.
Check Keyboard settings
Open System Settings > Keyboard. Check that Key Repeat and Delay Until Repeat are at normal settings (not at the slowest possible). Check that ‘Sticky Keys’ and ‘Slow Keys’ are NOT enabled in Accessibility > Keyboard — these are rare causes of ‘keyboard not working’ reports but they do happen accidentally. Also check for stuck modifier keys: Apple menu > About This Mac > hold Option while clicking System Information to open a special diagnostic view.
Test with an external keyboard
Connect any USB or Bluetooth keyboard to the MacBook. If the external keyboard works perfectly, the issue is definitely the internal keyboard hardware. If the external keyboard has the same problems, the issue is software or a stuck modifier key somewhere.
SMC reset (Intel Macs) or restart (Apple Silicon)
On Intel-based MacBooks, an SMC reset can sometimes clear keyboard-related firmware issues. Procedure varies by model — see our MacBook won’t turn on guide for the exact steps. On Apple Silicon MacBooks (M1 onwards), a full shutdown and restart serves the same purpose. SMC reset is worth trying if you are out of software options.
When individual key replacement vs full keyboard replacement
On older MacBook models (pre-butterfly), individual keys can sometimes be replaced — the keycap pops off and a new one snaps in. On butterfly-era MacBooks (2015-2019), individual keys can be replaced but the mechanism underneath is integrated with the top case, so major failures require replacing the entire top case (which includes keyboard, trackpad, and battery). On current scissor-switch MacBooks, individual keys are replaceable but the repair is delicate. At Indiana Phones we evaluate each case and recommend the most cost-effective option.
Keyboard-related liquid damage
The most common cause of sudden keyboard failure is liquid damage. Even a small amount of coffee, water, or beer spilled on the keyboard can short out the membrane and kill specific keys or the whole keyboard. On modern MacBooks, the battery sits directly below the keyboard, which means liquid damage often affects both. If you have recently spilled something, bring it in immediately — the faster we can open, clean, and dry the internals, the better the chances of recovery.

Frequently Asked Questions
Why is my MacBook keyboard not working?
Most common causes: debris in the keyboard (especially on butterfly-era 2015-2019 models), liquid damage from a spill, a stuck modifier key in software, or hardware failure of individual keys. Try compressed air and a restart first.
Can a MacBook keyboard be repaired?
Yes, but repair complexity varies by model. Pre-2015 and post-2019 MacBooks have more serviceable keyboards. Butterfly-era (2015-2019) MacBooks require replacing the entire top case for most keyboard failures, which is more expensive.
How much does MacBook keyboard repair cost?
Varies significantly by model. Individual key replacement on current MacBooks can be relatively affordable. Full top case replacement on butterfly-era MacBooks is significantly more expensive. Call Indiana Phones at (619) 577-3065 for a free quote.
What if I spilled liquid on my MacBook keyboard?
Turn the MacBook off immediately, unplug it, and bring it to a repair shop as soon as possible. The faster we can disassemble and clean the internals, the better the chances of recovery. Do not attempt to dry it with rice or a hair dryer.
