Service Process

Please choose one of the options below for service. Your Mac notebook will be examined prior to any service to verify that it is eligible for this program.

The type of service will be determined after the keyboard is examined and may involve the replacement of one or more keys or the whole keyboard. The service turn-around time may vary depending upon the type of service and availability of replacement parts.

Find an Apple Authorized Service Provider.

Make an appointment at an Apple Retail Store.

Mail in your device to the Apple Repair Center.

To prepare your unit for service, please backup your data.

Note: If your MacBook, MacBook Air, or MacBook Pro has any damage which impairs the service, that issue will need to be repaired first. In some cases, there may be a cost associated with the repair.
