Changing the keyboard or topcase

Hi everyone

Like a lot of people, my keyboard is &&^&*d up. The AZEQSDWC keys show weaknesses. When I press the A key it displays IOUYT etc...

After several messages read from everywhere, despite attempts to repair software and OS, none is working. So I conclude that the problem is the keyboard.

I've seen/read a lot of tutorials, but one question always comes up:

Why do I have to change the whole TOPCASE and not just the keyboard?

For now, the Mac Book Pro mid-2012 is completely dismantled, keyboard in hand, and I don't see why I should change the complete case. So maybe can someone explain me this ?

Thanks again! :)

Have you tried to use an external keyboard first before you spend money on this? Just to know its not a software problem.

Yes, when I had reinstall the whole system, in order to mame a good username and password, I used an external keyboard. And it was working ;)

I'm, not that much of an expert myself. but it makes sense to me...

Here's a tip! Open your Keyboard control panel and enable the show keyboard viewer in menu bar. Then opening up the keyboard viewer from the menu bar you should be able to see if the given keys mapping is messed up. So as an example you press the A key does the A key is the keyboard viewer show the A key being hit or some other letter?

From what you are describing when you press on a given key it does not show the correct letter on the screen. Did you have a liquid spill into the system? Is that why you’ve already taken the system apart?

As for your question: Do you need to replace the full uppercase or can you just replace the keyboard alone?

Both will solve a keyboard issue! It’s just a matter of skills you have. The newer version systems use plastic rivets so its not as simple as the older models which used screws Bobby’s @thatretro video shows the older 2009/10 model which uses screws. The riveted models are much harder and you will need to tap the holes for replacement screws (as well as have the screws) to replace the rivets.

Well, I have tear down the mac because to be honnest, I have found it in a dumpster area. The aluminium body was a little Scratch and I have replace RAM and HDD to SSD. Everything works perfectly good. Screen, sound, WiFi, OS, DVD… Except for 5/6keys on the keyboard. The Mac seems to be here since à few days, so I guess water had come inside.

About the skill, I guess I can handle it. I had repair a lot of smartphone, computer, tablet and mac. But never à Macbook Pro before. That's why my questions.

Thanks for the détails ! I'll wait for the keyboard. And if I can't do this… Well I'll assume I'll not as good as I though :p
