Macbook pro with key/s not working issue

murphydog999

I've got an ageing mac with a problem with the letter p and the hyphen/underscore and the question mark, none of them register (I'm using the 'show keyboard' to type this] I've taken the keys off and cleaned everything (nothing has been spilt on it} but it hasn't helped, all settings are ok. With the key taken off the keys that work beep when pressed, the others don't. 

Anyone know the next course of action please?

Most keyboards are electronic or switch activated.

Its plausible that the contact between the key and the electronic matrix underneath it is corroded/damaged.

Some contact cleaner (note:  WD-40 in its common state is not contact cleaner, it is a lubricant) if you have access to the circuit board may help.

I had this problem with several keys on my laptop. I found it easier to get a cheap second-hand macbook and transfer my hard drive to it.
Keyboards can be far too fiddly to fix.

Thanks guys. Not sure what happened but 24hrs (or so) after cleaning, everything started working again, and continues to!

I had a 2012 MacBook Pro that had several keys not working due to tea spillage. I found a replacement keyboard for sale for around £25. The only issue was is that the original keyboard was riveted in by around 100 tiny rivets. The fix is to buy a bag of tiny screws to replace them. Tedious but it worked.
