MacBook stuck with shift key enabled and numbers not working - even the keyboard app in languages wont type lowercase nor numbers?! Anyone know whats up? no spillage...cant understand why the keyboard app wont do anything.

Hi,

In my case , there was no spillage or physical damage to the Keyboard. The shift key was enabled by default and the F1 ,F2 ,F4,F5 keys were not functioning all of a sudden. I installed Karbiner and reloaded the xml and the keys started working fine. There is no problem with hardware as the shift keys are working fine,all the keys for that matter. But when i reboot the machine the shift key gets enabled and the system starts to boot in safe mode. Any idea on what I am going through ? Any help/suggestions would be much appreciated. Thanks in advance.

I don't know why I did not find this post in 2013 because I have been having this shift key problem for the past 3 years. I am so so happy that your solution has worked for me. I was so used to the KeyRemap4Macbook shift disable that I had stopped using the right shift key on my work keyboard too. :-/

Don't know how you managed to find that out. You're a genius. Thanks a ton. 🙂

I have remapped my keyboard so that the fn key acts as the left shift key because I don't use the fn key for anything else. Then I glued on an L shaped piece of thin sheet metal that covers both keys so that when I press the left shift, it also activates the fn key.

I am also having the same problem. My laptop shift key is stuck but it isn't and my macbook is starting in safe boot

I have changed the built-in keyboard but still it is not fixed having the same problem.

Is it possible to connect one laptop to another to use the keyboard of the working one?

I don't think so. But you should be able to connect a separate usb keyboard.

I think the best way to see if it is just the keyboard which is broken would be to borrow usb or wireless keyboard. If that also does not work, it is something more than the built in keyboard.

Mine was doing the same today.. I read a post which talked about disconnecting & reconnecting the keyboard cable.Did that to mine after giving it a thorough blow out.. Seems to be working..

Vinay,

Three days of research. It worked! You are now my friend.

It's worked. Recommend to everyone to give it a try before replacing the new keyboard.

Thank you so much @mrhurep!

Your solution worked so well 🙂

Back to work now!

Awesome! that helped me alot ! thanks so much 😎

Just to let you know that i had the same problem and just installed the new OS "Sierra" and it started to work again.

Try turning off Bluetooth. Worked for me.

Go to System Prefs and click on [Accessibility]. Check to see if Sticky Keys, Slow Keys or Mouse Keys are turned ON.

If so [Turn Them OFF].
