MacBook Pro Keys Suddenly Stopped Working (Y, U, I and O)

Well this was a fun morning.

Deadlines to meet, busy busy busy, and what should be the stumbling block?

Tricky PHP code?  No.

Gnarly CSS tweaks?  No.

No, no, no.  It’s just a simple case of my beloved MacBook Pro keys not working.

Say what.

Yup.  Keys.  Not working.

Crazy, I know.

So off to the Apple forums I electronically trundle.

This marvellous article (http://support.apple.com/kb/ts1381) keeps popping up, so I follow it all the way through, down to every last drop of detail.

Any luck?

No.

So I go off-piste.

 

And here’s the fix that worked for me:

  1. Go to System Preferences (you can get there from Mission Control, or the top left Apple icon on your screen, and then click System Preferences.
  2. Go to Keyboard.
  3. Go to the Input Sources tab.
  4. Click the + button (bottom left of window).
  5. Add a new keyboard (preferably of a similar language).  We had British running originally, so we added U.S. below it (i.e. you should now have 2 keyboards in the list).
  6. Your “broken” keys should now be working again (try with glee in an open text edit window, or similar).
  7. Feel free to remove your newly added keyboard (i.e. you should just be left with your original keyboard), as the fix should still work.  You can do this by selecting the newly added keyboard and clicking the button to remove.

So why does this happen?

No idea.  But it seems to be a software hiccup that’s tenderly reminded of all it’s appropriate keys when a new keyboard is added.

All I know is I can now get back to work. 🙂

 

Have we saved you some grey hair? Or made you smile?

    One of stupid solution which actually worked. In my case d,f,g,h,j,k,l stoped working (after like 20 clicks they responded). after removing U.S, and adding again it fixed. I believe this bug caused because of the latest apple update (somehow i not installed it for long time 10.10.1).

          If you’re still having no luck, then it might be that your keyboard needs a little spring clean – check out the solution at the bottom of the page here to see if that fixes the problem, although you may need to find cleaning instructions to fit your particular keyboard: https://discussions.apple.com/thread/1333288?tstart=0

    You truly are a genius! I’ve been suddenly having the problem with the exact same keys. This fix worked perfectly for me after trying several of the other ones in various threads. Was just getting ready to take my MBP apart to try the lifted cable fix I found on one of them. No need now, many thanks!

    My A,S,D keys suddenly stopped working when I was in college. It took me hours to write my papers because I had to stop and click on the keyboard viewer. After I graduated college, my keys decided to work again. I was aggravated but joyous at the same time. Then a couple of months later it stopped again. I stumbled onto your blog and did what you did but I added British instead. Did not work. I deleted U.S, again did not work. Added U.S. back and deleted British and voila!! It works! You’re amazing!

    This fix worked for me, but after I restarted my Macbook Air, the problem is back. And the fix doesn’t work anymore. So I will try other solutions, will post here if I find anything.

    BTW I’m writing this with an external keyboard, it works fine.

        I went to a repair shop and asked to borrow a USB keyboard to type the password 🙂 I changed the password to one with letters working, I’ve tried your trick Sara, but sadly didn’t work for me. At least I can keep investigating.

    Hi Sara,

    Your clever solution has worked for me in the past, but now unfortunately it’s not. (I’m using the stupid keyboard viewer to write this comment.) The y-u-i-o keys on my MacBook Pro simply will not respond at all, no matter what I do. Totally frustrating!!

    Any other ideas, short of taking the laptop in for service?

        Hi I also have an older MacBook Pro (Mac OSX 10.5.8) with the i and u keys not working .
        When I go to system preferences there is a keyboard section but no “input Sources” tab.
        There are Keyboard and keyboard shortcuts tabs at the top and these options in a side list : Dashboard & Dock
        Expose & Spaces
        Front Row
        Keyboard &Text input
        Screen shots
        Services
        Spotlight
        universal Access
        Applications Shortcuts

        I’ve gone through them all to see if they offered another keyboard.
        I’ve also tried the link you suggested but no joy!

          Hi Kirstin,

          Thanks for your post. I’m afraid I don’t have a Mac OS X 10.5.8 install handy, so I’m working a little blind here, however under System Preferences do you have a “Language & Region” (or something similar) option? If so, maybe try digging into the options and see if there’s anything keyboard related that will allow you to add (look for a “+” sign) a new keyboard language.

          Hope this helps!

    I initially did not remove the Italian keyboard while I added and removed the new British keyboard (I was following a different thred than yours unfortunately). Then today, Rubino (thanks) found your post and following exactly your steps solved the problem. Thanks Sara (and Rubino too) 🙂

    it’s definitely a keyboard language thing. for example if i have this problem typing in english i change language to spanish and the problem vanishes.

      for clarification, you can still type in english using another language keyboard but it solves the problem in my experience.

      Hi G,

      Glad it worked for you! It seems like an odd software bug, but no idea as yet what causes the issue. Since we stumbled across this fix the problem hasn’t surfaced again for us, so maybe it’s just a re-alignment of your keyboard preferences after a particular software update?

    I have a 2009 17 inch macbook pro. I bought it refurbished a few months ago. All of a sudden three keys stopped working: m, j, u. All in a line. Hmm. Sometimes if I try, for example, to type the letter ‘m’ once, it produces several different letters in a row. . I tried to add other keyboard languages as you said, but that didn’t work. I am typing this with my other computer.

    Amazing. Mid-2012 macbook pro (10.8.5) ghjkl keys were flakey, only by tapping multiple keys in succession would they work, then they would work for a minute, then get stuck. Cleaned everything, no better. Reset PRAM, toggled keyboard mouse settings repeatedly, no help. I can’t believe it was this simple and obscure,
    but golly jeepers lghjk keyboard switch works!

      If at all anyone gets this problem. Try opening the laptop, disconnect the keyboard from the motherboard (the connector is always near the battery try), by this I dont mean the whole keyboard, just the connector. Then wipe the connector with a clean piece of cloth then re insert it again and then switch on the laptop. The keys should be working fine. Its the connector that confuses the keys either because there is dirt or loose connection. All the best.

      NB PRAM, CMS Reset and all the above keyboard language change will not help. This is a hardware thing. Even reformatting wont help. I have done this and the only thing that helped is cleaning the connector.

        Thanks for your post – it’s helpful to know all the different solutions that have worked for others. Out of curiosity, did you give our solution a try before implementing your solution?

    Hi, my name is a Jack and I’m currently 21 and in College. I have a macbook pro using OSX I have been dealing with an issue for about 2 years now where my e,r,t,y,u,i and o keys suddenly stop working. My only remedy to solve this problem was to open up keyboard viewer and randomly click buttons till the unresponsive keys shortly after start working again. I get a unresponsive keyboard for the letters once every 2-4 minutes or whenever I wake my macbook up from sleep. I had tried using my windows operating system using bootcamp to see if the keys worked but I had the same result. I couldn’t get the keys to work at all on my windows operating system. I use my macbook pro a lot but because of my unresponsive keys I use a exterior keyboard most of the time. I generally would like to use my internal keyboard again without the hassle of spamming my keyboard till my keys work.

    I have tried have tried removing my windows operating system on my bootcamp, changed keyboard import sources and tried removing useless programs and clutter on my macbook. But I didn’t find a permanent fix or any improvements. I also tried looking into fixes online and this article is the closes I could find to my issue. I have read multiple tricks on how people have fixed their macbook’s keyboards and was wondering if anyone had a specific trick that might be suitable for my situation before I decide to backup everything and re-install Macintosh on my macbook. I am currently using my internal keyboard and mouse pad for this letter and have ran into the problem of unresponsive keys about 8 times.

    If someone could look into my issue I would greatly appreciate it.

    This did not work for me unfortunately any other suggestions? My keyboard keys are working in other users on my mac and when I put in my user password and on the keyboard viewer just not in my user account.

    Wow – after cleaning the keyboard, the O key itself, and then freaking out because it still wasn’t working, I found this – thank you!!

    What I have since discovered is that if you hold down any vowel key in notes, it produces an extra set of symbols…. not sure what that means… some kind of driver issue? Or perhaps it’s a corrupt English keyboard? Anyway, thanks again.

    it’s strange the keys that stop working always seem to appear in rows. this fix worked for me except my comma key. they keys that stopped working for me were i;k; and comma. this fix worked for all but the comma key which i’m guessing is a coding issue. the other people here have also had rows of keys stop working in bunches so it could be a hardware based input problem. gonna have to remap my comma key 🙁

        1. Sara Thornton Post author

          Have you tried popping the comma key off to see if anything looks out of place behind it? If all looks fine then maybe take it to a Genius bar to see if they can diagnose the issue.

          Hope you manage to get to the bottom of the problem, and please do let me know how you get on?

    Go into System Preferences and choose Accessibility.
    Choose Mouse and Trackpad.
    If Enable Mouse Keys is ticked, untick it.
    Then choose Options in this same panel and untick Press Option Key five times etc.
    In my case I apparently activated this Enable Mouse Keys. It still happens occasionally without my conscious input!
    After five frustrating calls to Apple help with no resolution of my problem I came across the exact description of the problem and it’s cure. I cannot remember how I worded my Google request to get there!
    All the very best,

    Hi Sara,
    I’ve had my keys in the center top letters row slowly lose their functionality. It started with “t” and the spread to the right. I did my due diligence of google searching and I came here after I tried resetting the NVRAM, which did not work. I tried adding a British keyboard (I’m in the US) but that did not solve the problem. However, it did get me to use the “keyboard viewer”. When I did so I noticed that the y, u, i and o keys, all of which were no longer working, would pop up their accent keys on the viewer. On a hunch, I disabled this through a terminal command (see http://osxdaily.com/2011/08/04/enable-key-repeat-mac-os-x-lion/) and restarted my mac. The “t” is still a bit wonky but the other keys have all reappeared.

    Hey,,, that solution worked on an email I was typing,, but now that I’m responding here, those keys are not working again,, now using my external keyboard. You guys need to figure this out… please!
    WTF is causing this,, obviously a soft ware problem,, yet my local Apple store was suggesting I would need a $250 keyboard replacement,, or perhaps it was a swelling batter,, or, my theory, the vibration of the internal speaker, located under this batch of misfunctioning keys, was the cause…

        Sarah, I just upgraded to the latest version of Sierra last night that was available, I believe version 10.5.5 On my 2013 MacBook Pro 15 inch . I was working fine prior to the upgrade as far as the keyboard etc. now the keys U, I, O, K, and M, will not function . I do notice that by depressing the K and M for a period of time, the cursor seems to move up and down very slowly as though I had the mouse keys enabled but I do not .
        I have read your thread above dating back to years and I have tried other options I have read such as, hitting it off and key five times in a row, enabling an additional keyboard and then removing it later, holding down all non-functioning kets, and and still I’m cursed with the same problem after this upgrade . I don’t use an external keyboard or mouse does have to rely on the internal keyboard and touchpad. Have you any additional ideas as to what I can try? Again, this works perfectly yesterday and only stopped working after I did the upgrade on the OS.

    hello,

    Had the same problem for a while and have given various things a go. For me, it was t,y,u,i,o keys. tried cold start, PRM, keyboard settings by country, nothing. I finally fixed it, there were a few hairs under my e key.
    Pull it out and get at it with the tweezers (and others if you can be bothered) works like a charm. Ive been using an external keyboard for months, I cant believe it.

    Firstly, I just want to say that its pretty shocking that this is an ongoing issue for iOS users since 20 4 (I cant type the number one, doh!)

Its like a disease thats spreading on my laptop!!! Im currently using a wireless keyboard just to be able to function/write this message but its rather annoying!

    So unfortunately your original post hasnt worked for me 🙁 I added the U.S. keyboard, then I added a few others (Irish etc) – deleted, readded – still not working. I see that you have been responding to everyone on here and posted quite a few links to alternative solutions, but theres quite a few links to go through so Id be really grateful if you could respond and send me the best link that you think will work for me.

    I had this problem for over a month on my Macbook pro 13 inches, early 2011. The row q-o just stopped working. I would intermittently work after pressing the “ö” key but it got to the point when I had to use an external keyboard. Apple does not service this model anymore…. so I was resigned to retire my laptop – after putting all the upgrades. After reading this thread, i tried it and it did ease up the problem a bit but I still encounter an intermittent key problem – although way less troublesome than before. Will continue observing. But I am grateful because now at least I am back to using my laptop without the external keyboard. Hopefully, shifting to another internal “keyboard” will permanently solve my problem. Thanks for this!!

    FWIW, I use Typeit4me for keyboard shortcuts. I had two keyboards installed in sys pref, US, and Typeit4me, the latter was selected when opened Sys pref. I followed the suggestion and installed the British keyboard, selected the US , closed sys pref and no dice. Then I returned to Sys pref, reselect Typeit4me and back in business, able to type “q” and “h” again. Hope that helps someone.

    Keys have been intermittently quitting on my wife’s MacBook Pro for some time.
    She was not happy with my interim solution of plugging in a usb keyboard.
    Found that it was specifically the yuio keys not working.
    So, I searched “yuio keys not working.”
    Found this page as the top hit on google.
    Did what you said by adding a British keyboard.
    Problem immediately solved.

    I know this is a bit of a necropost at this point, but…thank you for trying to address this problem, as I brought my (then still relatively new) macbook to more than one Apple store about this very issue—the Y, U, I, and O keys mysteriously deciding not to work. All they did was shrug and smirk (one of them actually winked at me, which to this day I find baffling). One told me he could install a new keyboard, but the price of that was basically 1/4th of the cost of the machine. So I just started using USB or bluetooth keyboards, which I still do whenever this issue pops up. I tried your method and frustratingly it didn’t work for me—at first it seemed to, but quickly stopped working again. Strangely this problem seems to have a confusing pattern. Some days those keys work fine, but other (most) days they don’t. The only thing I’ve noticed is that if you hold all four of them down for a moment, they start to work again for a few moments. If anyone figures out this bizarre and annoying glitch for certain, I will give them a gold medal. Anyway, happy to know you made it work for you.

        Thanks for your post Peter, and interesting to know that the issue has only gone away by staying on the British keyboard – how curious? Thanks for your feedback – every little bit of info gets us closer to solving the problem for those who don’t have success with our fix.

        Have a great day 🙂

    Ha! Well with both keyboards enabled, the tyuio keys still did not work. Removing the newly added British keyboard worked for about 30 strokes then not. Then off again on again.

    I have an older Macbook with the same problem. I stopped using it about4 years ago and started using it recently. The problem was no longer there.

    What to do!?

    Wow, this seriously just worked! My ‘z’ and ‘x’ key have only worked if I clicked them like 30 or 40 times, I might finally get on x or z to type. I was having to copy and paste z’s and x’s from other parts of the page.

    But I just tried your tip, *and it worked!*

    zzzzzzxxxxxzzzzxxxxxx <—— That's a lot of z's and x's suddenly! Would have taken me 10 minutes to get that many before.

    Thanks!

    Sara,

    Thank you so much for this post. My “J” key randomly stopped working yesterday and this post save me from having to search the entire internet or a trip to the Apple store to resolve the problem. I cannot believe that after 4 years this is still an issue.

    The only additional step that I had to take was to switch to the new keyboard once and then I could switch back and the key worked perfectly.

    Thanks,

    Tried what you suggested but unfortunately my keyboard did not magically repair itself. My situation is slightly different from your example. I have a bluetooth and an external keyboard attached to my iMac. All of a sudden, I was unable to input Q, W, E. R, T, Y. .
    I put the same bluetooth keyboard onto my Apple Mac Pro and it was fine. Suggests to me that it is likely to be some software glitch with my iMac.

    Here’s my problem:
    MacBook Pro early 2015

    The lowercase ‘y’ doesn’t work on the laptop keyboard or an external keyboard or even on the on-screen keyboard. The uppercase ‘Y’ works on all three. The external keyboard works perfectly on another computer.

    I’m typing ‘y’ by using a macro to insert it.
    I’ve tried all of the solutions posted here. None have solved the problem.

    Thank you for this helpful post! The time you took to explain this fix has helped me – and others, as well – a great deal. Several years have passed since this went up, so I’m not sure if anyone still follows this thread, but I just found it and solved my problems with typing f, g, h, j, k, and l. Hopefully, you will see this expression of my gratitude.

    Just in case someone sees this, I also have a couple of questions. The solution posted here works for one day, in my case, making it necessary to follow the instructions again the following day. Given that the fix takes less than a minute, I don’t mind doing it every day, but I wonder if there is a way to solve it permanently. Until I find this, I worry about keeping my computer password protected.

    Also, I wonder if this means that no hardware malfunction has caused this problem. On another site, I saw a claim that the wiring to specific keys might have shorted out, a problem that I would want to fix if it exists. Since the fix explained here works, it would seem as though this could not be caused by a physical flaw in the machine, but perhaps I misunderstand this; I would happily see any responses that clear this up.

    All the best,
    Marco

    Didn’t work for me and I have the EXACT same issue, nowhere can I find help, I have a 20 year old dell keyboard plugged into my modern MacBook because of these keys not working, I can’t afflrd the crazy expensive Mac support, and I’m shocked to not be able to find answers online for this issue, here’s someone with exact same issue, even same exact keys, but problem is still there. It’s not the actual keys, it’s a software or hardware issue of some sort.

    Thank you so very much Sara. I tried all I understood similar to the problem fixes introduced/described in this article. I was ready to replace my keys or buy another keyboard, but thought, since I was able to get them (dfghjkl) to work by hitting multiple keys simultaneously that the keys were not the problem. I turned to System Preference, but forgot about the “input sources” option. I had used it once before for the top keys.. You probably helped with that one too. Bet U have a halo. Enjoy the coffee ;0)
