Should I buy an external keyboard if a laptop key fails?
Answer when one failed laptop key justifies an external keyboard, key repair, cleaning, remap, or laptop keyboard service.
Short answer
First rule out layout, remaps, stuck modifiers, and debris. If one laptop key stays silent in a raw keyboard test and repair would take time, an external keyboard is the cheapest reversible workaround.
Confirm first
Test the failed key in the browser.
Check layout, remaps, debris, and stuck modifiers.
Use external input while deciding on repair.
Why this matters
HWProbe keeps the answer tied to evidence: run the matching browser test, try the reversible fix, then replace only when the same fault repeats. Tests run locally in your browser at hwprobe.com.

Frequently Asked Questions
Is an external keyboard better than laptop keyboard repair? +
It is usually faster and reversible. Repair is cleaner if you need portability, but an external board can keep the laptop usable immediately.
Can a remap avoid one dead laptop key? +
Sometimes. If the failed key is rare, remapping can work. If it is a frequent key or modifier, external input or repair is more practical.
