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 the problems involve only a "small percentage" of laptop keyboards. But the malfunctions have been widely reported, 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 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 over to the butterfly keyboards.

Presumably, the company is sticking with the butterfly switches. And according 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 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.

"Apple knew or should have known of the butterfly keyboard defects before the Laptops were ever sold to the public," the lawsuit alleges.

To use the repair program, eligible MacBook owners need to make an appointment at an Apple store or find an authorized company service provider. You can also mail your MacBook to Apple's repair center.

If you paid up for the expensive keyboard repair in the past, Apple said it'll offer you a refund. All you have to do is contact the company.
