Sticky Key on Your MacBook Keyboard? Here's How to Fix It
This technique can help you remove fluff, fizz and debris that's stuck under your keys.
Got sticky keys? Grab a can of compressed air.
Tired of the "I" key on your MacBook's keyboard never pressing down because you spilled some sticky soda on it months ago? Unfortunately, you have sticky key syndrome -- that's when dust, crumbs or other gunk gets stuck under a key and keeps it from depressing easily. It's annoying and keeps you from working as efficiently as you could.
If your first instinct is to reach for a can of compressed air to clean underneath those keys, you're on the right track. But you don't want to just aim and shoot because you may miss some of the hidden debris or lodge it further under the key.
Keep reading to learn a technique that works well and will help keep you from emptying a whole can of air for nothing. On the flipside, if you find there's no gunk underneath, you may have a dead key, which is a bigger problem for you because Apple will have to replace the keys (which could take several days). Here's how to find out.
Keep your MacBook's keys free of debris.
How to clean your MacBook keyboard, step by step
1. Make sure the straw is securely attached
When you purchase a can of compressed air, it comes with a thin straw taped to the side of the can. Make sure you snap it into the nozzle before you begin, and make sure it's a snug fit. If it falls out as you begin, you'll need to reinsert it.
2. Turn off your laptop and unplug it from the power cord
Before you start spraying your keyboard with compressed air, make sure you've got the laptop powered off and unplugged. You don't want to accidentally press buttons that could delete important documents or type in a bunch of random characters if you disturb the keys during cleaning. You also don't want that cable getting in your way.
3. Turn your laptop upside down
To get rid of any loose debris or crumbs, turn your laptop upside down and lightly tap the bottom. That'll mean less work the compressed air has to do.
Power off your MacBook before you start cleaning the keyboard.
4. Position your MacBook the correct way
Make sure you're holding your MacBook at a 70-degree angle, rather than vertically. This is so the debris can fall out cleanly and away from your keyboard. The last thing you want to do is allow the gunk to fly under another key.
5. Start spraying
Continuously press down on the nozzle for an even stream and slowly spray the compressed air in a methodical zigzag pattern across your keyboard. Save the short bursts for spot-checking after you've done a thorough cleaning. Start with the top left key and stop at the last key on the bottom right so that you don't miss a spot.
Spray your keyboard from left to right in a zig-zag pattern.
6. Place your MacBook on its left side
Using the same zigzag pattern, spray the keys again. This time, you'll start at the fn (function) key.
7. Rotate your MacBook to its right side
Again, use the zigzag pattern to spray your keyboard with the compressed air. Start at the top-right key -- this varies, depending on which MacBook model you're using. It could be the power key or delete key.
8. Wipe up or vacuum away any remaining pieces
If you've got visible crumbs still hanging out on your keyboard, use a small vacuum tool to remove them. Once you've done that, give your keys a good wipe down with an electronic cleaning wipe. Ditto the floor or whatever surface the gunk has fallen onto.
Never spray liquid on your MacBook's keyboard.
What you shouldn't do
Never spray liquid of any kind onto your keyboard. This can cause water damage and leave you with a worse situation than sticking keys. Instead, use a damp cotton swab to gently clean the keys or an electronic cleaning wipe.
If you've got a butterfly keyboard, don't ruthlessly pry the keys off because it can cause damage to the butterfly clip mounts. Instead, place a thin flat tool underneath the edge of the key and gently lift up.
No luck? Visit your nearest Apple Store
If your keys still aren't working after you've cleaned from every direction, there may be a much larger issue causing your keyboard to not work. Make an appointment to visit your nearest Apple Store to get your MacBook serviced by the Genius Bar. Apple employees can determine if the key needs to be replaced and can give you the estimated time it will take to do so.
If you don't live near an Apple Store, you can mail your MacBook to the Apple Repair Center.
