If you have unresponsive keys on your keyboard or some keyboard keys fall off, you can fix it in a few simple ways instead of replacing your entire keyboard. However, you need to learn the proper procedure so that you do not end up doing more harm than good.
This article will guide you in fixing a key according to the underlying issue.
Fix a laptop keyboard key
Since a laptop keyboard has three components (key cap, key retainer, and key pad), we will fix them one by one.
Loose key cap
If the key cap is loose but not entirely detached, you can fix it by pressing it down. If you hear a snap, it means the problem is fixed. If not, then remove the key to re-attach it.
Broken key cap
If the key cap, retainer or key pad of your laptop keyboard key is physically broken, you may need a replacement key. If you cannot put the key back onto the keyboard, first place the retainer on the laptop keyboard. Now place the key pad and then the key cap. Press it down till you hear a snap.
Fix a desktop keyboard key that has stopped working
If certain keys on your desktop keyboard are not working, you need to run a few checks before getting a new keyboard.
You can try cleaning the entire keyboard with canned air. If you need to remove the keys to clean underneath, you can use a flathead screwdriver or some other household tool for the purpose.
You can also restart your pc to see if it works. You can also connect your computer with another external keyboard or enable the on-screen keyboard to see if they are working. If yes, then the problem is with the keyboard.
If it is still not working, you can adjust keyboard input settings or reinstall the keyboard driver. Alternatively, run a malware scan to see if it resolves the issue. If the problem persists, you may need to replace the keyboard.
If your MacBook keyboard keys are not working, and you are not sure where the problem lies, consider consulting an Apple authorized service provider.
