In a statement provided to Apple blog 9to5Mac, an Apple spokesperson said: "Today we launched a keyboard service program for our customers that covers a small percentage of keyboards in certain MacBook and MacBook Pro models which may exhibit one or more of the following behaviors: letters or characters that repeat unexpectedly or don't appear when pressed or keys that feel "sticky" or aren't responding in a consistent manner". The company says the issues are limited to a small percentage of MacBooks, but its offering free repairs. I was able to get it fixed for free because I had purchased AppleCare; the repairs could have otherwise cost me more than $700, based on the receipts given to me by Apple with the fix.
Reportedly, the butterfly-mechanism keyboards fail when they encounter dust. One corporate issuer of the MacBook Pros in question reported to me that its business has encountered a significant number of keyboard issues, but "less than 5% for sure".
After months of outcry from angry customers, Apple has finally acknowledged that the new keyboards have some serious problems. Apple says that models affected are covered by the Keyboard Service Program for four years after purchase, although this does not extend the general warrantly coverage for the devices.
These butterfly keyboards have proven divisive among consumers.

The problem, caused by a faulty butterfly key switch mechanism, caused numerous laptops' owners to experience keys that stuck, or failed to function as intended. Apple previous year even posted a support page detailing how users can use compressed air to clean out the keyboard themselves, however, that reportedly doesn't always work, with the issue returning.
Indeed, even a single faulty key can demand the whole keyboard be replaced.
Following a lawsuit that was filed, Apple has finally acknowledged the issue and has launched a fix program. Jason Snell, editor of Six Colors and former editor-in-chief of Macworld magazine, wrote in April 2018, "Apple's relative silence on this issue for existing customers is deafening".
