Attention, MacBook owners with faulty keyboards: Apple will fix them for free.

The repair program applies to MacBook and MacBook Pro models with keyboards that unexpectedly repeat letters, fail to type them, feel “sticky,” or respond inconsistently.

Apple said(Opens in a new window) the problems involve only a “small percentage” of laptop keyboards. But the malfunctions have been widely reported(Opens in a new window), with critics pointing to the ultra-thin “butterfly” switches inside the technology as the key culprit. Apparently, the switches are so delicate that the mere presence of dust(Opens in a new window) can force them to fail. And unfortunately, fixing the problem isn’t easy; at worst, it can involve replacing the entire keyboard.

In Friday’s notice, Apple made no mention to why the keyboards were faulty. Nor did it say how the new replacement keyboards will remain error-free. The company simply said the repair service applies to MacBook and MacBook Pro models from 2015 and onward, when the company began switching(Opens in a new window) over to the butterfly keyboards.

Presumably, the company is sticking with the butterfly switches. And according(Opens in a new window) to The Outline, the keyboard repairs Apple has offered in the past don’t permanently fix the typing errors.

Apple announced the repair program after customers filed class-action lawsuits(Opens in a new window) against the company over the flaky keyboards. One lawsuit claimed that thousands of consumers had been affected and that replacement costs to fix the keyboards ranged between $400 to $700.
