Many laptops nowadays come with a keyboard lock feature which can be enabled or disabled through a combination of keys. This feature is essential to prevent accidental keypresses while performing specific tasks.
Several factors, from switching the device to tablet mode, driver issues, or third-party keyboard software, may lock your Dell laptop’s keyboard.
To fix this, press the required key combination to disable the lock or change the device to laptop mode. If changing these settings does not work, you can perform the following fixes to make your Dell Laptop’s keyboard responsive again.
Check for Fn Key Lock
If only the Function row isn’t working, the Fn key lock might be causing this problem. The Fn key, combined with another key, can cause the Function row to become locked.
To fix this, press the (Fn + Esc) keys to disable the Fn key lock. The unlocking combination may differ depending on your device model. You can check your device’s support page or the instruction manual to get detailed information on the key combination.
Run Dell SupportAssist
Another general fix is to run the Dell SupportAssist application. This software can diagnose any hardware or software-related issue of your Dell laptop. By running this, you can check and resolve any problems related to the keyboard.
- Open the Dell SupportAssist application
- Click on the Troubleshooting tab
- Select “I want to check a specific piece of hardware”
- Scroll down and select the Keyboard from the list
- On the new window, perform the tasks as displayed on the screen

For devices running Windows 11, you can restore the keyboard functionality by simply reposing the device back to laptop mode.
Unlock using Num Lock
If only the number pad isn’t working, check if the Num lock key is disabled. If that is the case, the keys will perform their alternate function instead of typing numbers.
To fix this, press the key and see if the Num Lock light turns on. If the light is on, press the number keys again to check if they work.
Disable Filter Keys
Your Dell laptop’s keyboard might respond slowly or not register any keys pressed if you have enabled the Filter keys setting. Disabling this function can restore the responsiveness of the keyboard.
