The MacBook Pro Retina 15-inch Mid 2015 (A1398) uses a chiclet-style keyboard permanently riveted and screwed to the top case with over 70 fasteners.
Keyboard replacement requires full disassembly of the top case, including removal of battery, logic board, and trackpad for internal access.
The OEM replacement keyboard includes a matching backlight and offers consistent key travel and response comparable to the original unit.
This repair is commonly performed when multiple keys are unresponsive, backlight fails, water damage occurs, or keycaps are broken beyond repair.
Typical repair time is 2–3 hours, with 3–6 months technical warranty depending on part quality and device condition.
