Whether it's a few dead keys or the whole keyboard, the cause is usually one of a handful of issues — and many are fixable without a replacement.
Quick Checks First- Restart — a frozen key handler is common and a reboot clears it.
- Check Filter Keys / Sticky Keys in Windows settings — these can block input.
- Test the on-screen keyboard — if that types fine, the issue is hardware, not software.
- Update or reinstall the keyboard driver in Device Manager.
- A few keys — often debris or a worn membrane under those keys; sometimes cleanable with compressed air.
- Whole keyboard dead — usually a loose ribbon connector or liquid damage.
- After a spill — act fast; corrosion spreads to the board if left.
A keyboard replacement is quick and affordable, and a technician can confirm whether a clean, a cable reseat, or a full replacement is needed. If a spill caused it, get it looked at soon to protect the motherboard. Most keyboard repairs are same-day with a warranty and free pickup — and a USB keyboard gets you working in the meantime.
