Random Keys Working Sporadically

I have a MacBook Pro OSX, that I bought about 4 years ago. It has worked PERFECTLY for me. Until now. What is happening is at RANDOM times and for RANDOM lengths, a few keys (t,y,u,i,o) will STOP working. It is totally random and there seems to be no pattern to it at all - they simply will work, and the stop, and then work again (as you can see, they are working NOW). I brought it in to the local computer shop (Best Buy) and they did a hardware analysis to see if the keyboard was broken. It came back and said the keyboard was functioning fine. I don't know what to do at this point?? I've read about the battery perhaps swelling up and causing this, but IDK...ANY help would be GREAT!!!!

Hello MattyRay,

The following article provides some useful troubleshooting steps that can help resolve issues with your keyboard.

One or more keys on the keyboard do not respond

As a data point I have a late 2011 macbook pro and it started doing the same thing.  The 'k' and 'l' keys so far but random when they cut out and random for how long they don't work.

I, too, have a 4 year old Macbook Pro, and I am having the same problem. I have updated all my software and have done everything on the article allen a posted for troubleshooting my keyboard. Still having problems! This all started with my "D" button. Now it's my "L" and "K" buttons. Even typing this, I can't hit those buttons once and have the letter just pop up. I have to hit it repeatedly to get it to work. It's almost like there's a massive delay between when you hit the button and when the letter actually appears on the screen. When I opened my "Keyboard Viewer," sometimes it was showing my button highlighting when I hit it, and sometimes not at all. This is extremely frustrating! I really don't want to take my computer in, but I'm worried that's what I'm going to have to do if there isn't any other way to fix this.

I've had a similar problem for a while, too. Granted, it's a 2009 Mac Book Pro 17" Unibody, but it's not sustained any damage (dropping or liquid).

What's really, really strange is that 20 minutes ago, several keys on my homerow (I use the Dvorak layout) weren't working: i, d, h, t, n. Then, without restarting, without really doing anything, the keys started working fine. The first paragraph of this message was typed without any problems  until I got to the letter "I" in liquid.

Now, I'm typing those letters with the on-screen keyboard or Dictation.

I'm really baffled about when it stops working, when it starts working, how long it lasts.

I have reinstalled the operating system, Mavericks, on an external disk and booted from that. I have installed no extra programs, copied no data - it's a clean, clean system. But, still the problems are intermittent.

Unfortunately, I'm living in Geneva Switzerland right now, and the Apple Store here is not very good.

Just confirming that 20 minutes ago my keyboard was doing the same thing, even the same keys, which makes me suspicious.  I have a Spring 2011 macbook pro.  All is well now, but I will keep an eye on it.

@MattyRay, please post back if you find a fix.

I have the exact same issues for my Late MBP 2011. This was the first post that had the same keys in question not working (t, y, u, i, o).

I tried cleaning under the keys but that really didn't help. I also tried the things in their support article, but they didn't work either.

I'm still looking for a solution, but when it stops working, sometimes it helps to press down hard on the area where the t, y, u, i, o letters are. Maybe that is just psychological, though. I don't think I had any issues with a USB/bluetooth keyboard, so you can use that too. It is just odd that it *sometimes* works and *sometimes* doesn't. It makes one assume that something is loose or not reacting properly...

It happened to me sporadically for 2 days, and since it has been fine.  I did try to wipe down my keybard and blow air around those keys.  But I never found a solid answer as to what the cause and real solution were.

Hope you get lucky!

Omg, adding that I'm having the exact same experience: Spring 2011 MacBook Pro, and my t, y, u, i, and o keys work only sporadically.

We fixed the issue for a while (messed with the ram, repaired disk permissions, cleaned out a ton of things in the hard drive library per some online suggestions), but it's back again after 3 weeks of keyboard bliss. I'm using an external bluetooth keyboard to type this.

The problem's recurred for the last 8ish weeks -- enough time for me to notice that this seems to happen during the same periods when my laptop starts to easily overheat. Like, my laptop seems to have "seasons" during which I suddenly have to prop books beneath it (when working in certain scenarios) in order to keep the fan from running high.

Not sure if it's coincidence that the keys get intermittent during these times, but it's def curious. ?

If anyone finds a solution, please let us know!

Same issue for 13" MBA mid-2011 for all keys from Q to O (not P,.. yet), started yesterday. Very annoying since my password has some of them, and also reloading (Cmd+R) does not work. It starts working again if I press one of the keys for long time.

Edit: I have a "service battery" warning since a while so I guess it's time to fix it.

finally after months of research and not finding the answer here is the trouble shoot for you key problems.

just tap option key 5 times in your keyboard and your set to go.

hope it helps.

Oh my god. Are you kidding me?? This sounded ridiculous, but at this point, I'll try anything.

So the option key didn't work, but you may have meant the ctrl key? Because I tapped it 5 times, and here I am typing on my macbook pro keyboard for the first time in over a week.

What. The. F.

Early Spring 17" Macbook pro and having the same issue.  2 days ago y,o,h,l,n,0,., and arrow keys stopped working. For a moment 'control' locked on but that faded away after an hour or two.

- Pressing keys 5 times ( opt, alt,cmnd,shft) does nothing. 

- I have checked all preferences (speech, dictation, universal, keyboard, text) as mentioned in blogs. 

- I have also created a new user to varify there is no issue with specific account preferences.

- I reset RAM ( press & hold Command-Option-P-R keys before the gray screen appears on restart )

Keyboard viewer shows nothing when pressing these keys however when keys are clicked through keyboard viewer they works fine. 

I noticed this began after I wiped off my keyboard while the computer was on (on the log-in screen) which is why I thought that this could simply be some bizarre setting I mistakenly turned on while pushing multiple keys that renders keys non functional but after reading 8 hours worth of online tech support, blogs, etc., nothing suggested works.  I am careful with my Mac and have gently cleaned it the same way I have been since 2011. This is the first keyboard issue.   There seems to be a lot of people with this same problem, I hope there is a fix I am overlooking.  I am going to the Mac Store today and will update with issues. 

I've heard Macs are 4 year machines before the built in obselete features kick in. I definitely love this 17" so I hope this is just of single, correctable glitch. 

and sidenote, if the new iphone is not waterproof I may just be convinced Apple has lost its competitive edge.     

I have a MacBook Pro purchased in 2010. Letters A through L on my built-in keyboard (the entire middle row of letter keys) have stopped working. At first it was sporadic but now they seem to be out for good. This problem just developed over the past few days. I've tried all the troubleshooting suggested. Nothing works. I'm typing with an external bluetooth keyboard now. From what I've read, it could be that the battery has warped and is affecting these keys? Hesitant to buy a replacement battery given the machine is already four years old and may just continue to deteriorate...

I just started having the exact same issue as AndreiX this evening with my Mid 2012 MBP Retina. I discovered quite at random that if I press hard on the case on the speaker grilles to either side of the affected row (QWERTYUIOP), it starts working again. I think this lends credence to the theory that there's a loose connection somewhere under the keyboard.
