Symptoms
- Most keys work but a few specific keys don't respond
- Dead keys are often clustered in one area
- Keys feel physically fine when pressed
Likely causes
- CommonDebris or crumbs under the affected keysFood crumbs and dust are the most common cause of a few unresponsive keys.
- PossibleSpill residue affecting a localized areaEven a small spill can leave sticky residue that blocks contact under specific keys.
- PossibleWear in the keyboard's membrane circuit at that spotHeavy use over years can wear out contacts under frequently used keys.
What to do
- Turn the keyboard case upside down and gently tap or shake to dislodge loose debris.
- Use compressed air between the keys to blow out crumbs and dust.
- If a spill happened, wipe the surface and let the case fully air dry for 24–48 hours before testing again.
- Test the affected keys in a plain text field to rule out an app-specific keyboard shortcut conflict.
- If specific keys remain dead after cleaning and drying, the keyboard membrane in that spot may be damaged and the case likely needs replacing.
