MacBook Keyboard Keys Not Working or Repeating
Troubleshoot isolated keys, repeating input, backlight problems and spill-related keyboard failure.
Stop and seek help: Disconnect power if you notice battery swelling, liquid exposure, smoke, a burning smell, severe heat or damaged charging contacts.
Determine whether the issue is physical
Test in more than one application. If the same key fails everywhere, inspect for debris or a changed key feel. If many keys fail in a pattern, a connector, top-case circuit or liquid path may be involved.
Use an external keyboard as a comparison
A wired or Bluetooth keyboard can help you log in and determine whether macOS accepts normal input. It does not repair the internal keyboard, but it helps separate software settings from internal hardware.
Treat spill symptoms seriously
Sticky keys after coffee, soda or water are not only a cosmetic problem. Liquid can travel below the key mechanism and reach the keyboard matrix or logic board. Do not flood the keyboard with cleaner.
Understand repair construction
Some MacBook keyboards are integrated into the top case and require extensive disassembly. Others may support a keyboard-only procedure. Model, layout and physical condition affect the correct repair.
