New York (CNN Business) Apple has another fix for its troubled laptop keyboards.

Following ongoing complaints over broken and sticky keys, the company said Tuesday it is changing the material used in its butterfly keyboards — which are found on most MacBook Air and MacBook Pro computers — and expanding its repair program.

Less than a year after the debut of its latest MacBook Pro model, the company announced a faster 8-core MacBook Pro with one very notable change: a slightly revamped version of its third-generation butterfly keyboard.

Apple AAPL didn't disclose details over the change in material, but said it believes the update will significantly cut down on user complaints.

The MacBook Pro line starts at $1,799 for the 13-inch model and and $2,399 for the 15-inch version.
