Why is my MacBook shift key always pressed?

My right shift button wasn't working. I took it off with a paperclip in order to clean around underneath. After putting the key back I was confronted with a far more annoying problem—the computer is now registering that the key is always being pushed. I restarted my laptop, which was a terrible idea, because now I can only boot in safe mode.

Ideally, I'd like it all to be better. How could I possibly fix this key? If not that, I'd at least have it not working again in the sense that it isn't stuck "on" anymore. There are a limited number of things that I can do from "Safe Boot," and it totally sucks. Worst comes to worse, is there a way I can just completely disable my internal keyboard so that I'm only using this external one? Apparently it doesn't register as connected until AFTER my computer has booted in to safe mode.

Any suggestions? :)

i have this problem aswell. I'm on the edge of ordering a new topcase for my 17 inch unibody MBP.

the system just thinks i always have the shift key pressed in. I already removed the key but there's no difference.

what if it's not the keyboard?

what more could it be???

I don't want to order the topcase only to find out it's not the shift key.

I have the same problem but I don't see any answer here. How do you remove caps lock key or shift key?

por

Pry them up from underneath the top edge. Spudger, tweezers, small flat blade screw driver.

Hi guys, I have the same problem and the same Macbook of your. But I have also FN stuck . I tried reinstall mac os x, the problem remains. I think that the problem is firmware because I tried Live cd ubuntu and the keyboard work greatly. Do You think the problem is firmware? What I have to do if it's a firmware problem?

Turn the computer off, take off the shift key, and reboot the Macbook. If the computer boots as it should, make sure to reinstall the key correctly. I guess the scissor mechanism or the metal arm under the key is not well fixed.

Or something could be caught underneath pressing on the little nipple that actuates the key.

I had a similar problem, the left shift key appears to be damaged, it doesn't feel 'right' when pressed. The machine works perfectly with a USB keyboard. Apple are only interested in replacing the whole keyboard, and say they may need to replace the top cover too. Not cheap! I'm not too confident about fixing the key myself, so I used a software fix.

I downloaded and installed KeyRemap4MacBook, then disabled the left shift key, clicked on the 'Reload XML' button, and all now works OK, except i can only use the right shift key, which isn't a huge issue. Caps lock is still OK.

This fix is at the software level, so you still need to hold down the option key to bypass safe boot. You also need to go into the system preferences and add KeyRemap4MacBook as an application that should start on login.

I spilled some milk all over my keyboard a month ago. It has slowly been improving (keyboard didn't used to work, but now it works near perfectly). The only problem that I still have is that the left shift button seems to be stuck.

It was mentioned above in this discussion that the c or esc button needs to be held down to not boot up in safe mode with a stuck shift key. This did not work for me. I held down the option key and that worked for me. Finally out of Safe Mode! I'm on version 10.7.5

While I was investigating my problem of a stuck shift key I found multiple answers that pointed in a faulty mainboard direction (I had a moisture spillage on the laptop).

After the spillage had happned I disassembled the complete laptop, put the top cover with glued-on keyboard complete in a very hot water tub and let it stay there for a while, to clean out the moisture residue, also the trackpad which didn't register hardware cilcks anymore. I managed to compeltely clean out the microswitch under the trackpad, it clicks really snappy again but it still doesn't work, neither was the problem of the stuck shift key solved. You can switch "Touch pad to click" on in settings and that works once booted.

Currently I'm using the macbook pressing C or Esc key while booting (both work in snow leopard) and I use a small wireless iMac keyboard with it as external keyboard. I already tried installing OSX Lion on this macbook but had to revert to leopard, no audio/webcam and unable to do a normal system boot. I thought I had a corrupt lion install but swapping the lion harddrive to my mac mini worked ok. I must admit i didnt know about pressing C during boot maybe that still works under osx lion.

I have a macbook that's had a spillage on it. A couple of keys don't work and the shift key randomly decides to stay active when it feels like it. Removing the actual key itself makes no difference and there is no sign of the little rubber nipple being stuck down so it must be damage to the actual inner workings of the board. Is there any way of actually disabling a key at firmware level that anyone knows of so it doesn't register any more even at boot?

I'd like to be able to just deem that key completely unavailable as much as it will suck having to use the right shift key as standard.

Any one got any ideas?

Thanks in advance.

Dear all,

I have the same problem as the previous user.

My macbbok Pro unibody Mid 2010 is seen the left SHIFT button as always pushed, also at start up -> therefore it boots in safe mode.

I was reading that disabling the internal keyboard (taking out the connection from the logic board) means disabling also the POWER button.

Is there a way to manually connect the power button to the pins in the logic board for turning the mac on?

thanks a lot.

I had the same problem with my MacBook Pro 13.3" A1278 year 2010 and after replacing the keyboard it's still doing the same thing. Replacing the keyboard will not fix this issue 100% as once my logic board was repaired then it's all working fine.

P.S. I also had issues with running applications as it would highlight 20-30 programs when just choosing one to run, that also has been resolved after the logic board repair because of an ounce of water spillage.

Attach any (doesn't have to be Apple) USB keyboard before booting and use that.

Hi, I have had the same problem. Girlfriend's wet hair dripped onto keyboard! I have installed KeyRemap4MacBook and tried to disable the shift key but it hasn't worked and I dont know why. It appears the Return key isn't working either.

Do I try taking the keys in question out and checking for water damage?

Do I just buy an external keyboard and make do?

Do I let it be and hope it fixes itself?

Or is there another way of me fixing it so that i'm not forever in CAPS LOCK and don't have a Return Key?!

Thanks!

I have 6 keys that don't work. 5 in same sort of area (Return key and shift key to name two of them) so would point at water damage in that spot but then the other key is the other shift key on opposite side which is weird! I'm just concerned having the keyboard replaced might not solve this? How much did it cost replacing the keyboard and where from? Many thanks

Easy fix, just use the free Karabiner app to disable the stuck key. Also Ctrl+R at boot to enter recovery mode, where you can add a firmware password to make it boot straight to login, might be wise to set a password in all caps as Karabiner won't start up at that stage. You can try using compressed air on the keyboard to clean it, that worked for me.

I to have the same problem, at first the right arrow key continues press down after booting, but now the shift key continued being press down so it boot at safe mode, so I restart and press the command key or any key before the apple logo comes out and came out of safe, by the way the arrow key does not bug me anymore right after the shift key become my new problem.

Finally, I resolved the issue by cutting wire of shift key.

The caps key has also been sacrificed, but I can avoid the issue that always boot safe mode.
