Single keypress types repeated characters (MacBook Pro 2016 & 2017) I previously used a MacBook Pro 2016, and I had problems with the b where the key produced a bb about one third of the time I hit the key. After getting it repaired, several months later, the same problem started with the N key. 

I now own a MacBook Pro 2017, and I have the same problem with the M key, but maybe with an occurrence of only one in forty, which makes it much harder to demonstrate.

It's always the same zone on the keyboard, I was wondering if anyone else was experiencing the same problem and what they did to fix it?
Finally, if anyone had or has the same issue, Apple is replacing the keyboard free of charge / refunding the past repair :

UPDATE. There is a small program, called Unshaky written on Swift. It fixed this issue for me.  It lets you configure a timeout for each key to suppress duplicate keypresses. For instance, if the 'e' key is giving you trouble, you can configure the timeout for a longer duration and adjust for the best results. There is also a statistics panel that shows how many times a key was suppressed by the software, as well as a detailed breakdown for each key.
