To unlock your Logitech keyboard, the fastest fix is to check and toggle the lock keys that were accidentally pressed. Most "locked" keyboards are simply in a state where Num Lock, Caps Lock, Scroll Lock, Fn Lock, or Game Mode is enabled, and pressing the right key instantly restores normal typing.
First, toggle the lock keys: Num Lock, Caps Lock, and Scroll Lock
Press the dedicated Num Lock, Caps Lock, and Scroll Lock keys one at a time to see if any of them were accidentally turned on. If your keyboard lacks a dedicated Scroll Lock key, use one of these combinations: Fn + S, Fn + C, or Fn + K. Alternatively, open the Windows On-Screen Keyboard by pressing Windows key + Ctrl + O, then click the Scr Lk button to toggle it off. This is the quickest way to resolve a keyboard that suddenly stops typing normally.
Unlock the Fn key functions
If your media keys (like volume or brightness) are acting as the default instead of the standard F1, F12 keys, the Fn Lock is likely enabled. This lock reverses the behavior of the top row of keys. To unlock it, hold down the Fn key and press the Escape key. After doing this, test the F1, F12 keys to confirm they work as intended.
Turn off Game Mode on a Logitech gaming keyboard
Many Logitech gaming keyboards have a dedicated Game Mode key, usually marked with a joystick icon. When Game Mode is active, keys like the Windows key are disabled to prevent interruptions during gameplay. Press the Game Mode key once to turn it off; an LED light typically indicates when the mode is active. You can also customize which keys are disabled in Game Mode using the Logitech G HUB software.
Check the power and wireless connection
For wireless keyboards, start by checking and replacing the batteries with correct polarity, or recharge the keyboard if it has a built-in rechargeable battery. If the keyboard uses Bluetooth, ensure Bluetooth is enabled on your computer. To re-pair a Bluetooth keyboard, press and hold an Easy-Switch key (if available) until its LED blinks, then go to your device's Bluetooth settings, select the keyboard from the list, and enter a pairing code if prompted. For keyboards using a Logitech Unifying receiver, open the Logi Options+ app (or Logitech Unifying Software for older devices), select "Add Devices" under Unifying Receiver setup, turn the keyboard off and then back on, and follow any on-screen instructions. This process will help you reset a Logitech wireless keyboard if it has lost its connection. If the keyboard remains unresponsive, you may need to unlock a Logitech wireless keyboard by disabling its specific function-key lock combination.
Update software and test on another device
Update or reinstall Logitech software (Logi Options+, or G HUB) and keyboard drivers from the official Logitech website to resolve potential software conflicts or outdated drivers. Logi Options+ is the recommended next-generation customization software for supported Logitech devices, compatible with macOS 12 or later and Windows 10 or later. If the problem persists, test the keyboard on another computer or device to help determine if the problem lies with the keyboard itself or with the original computer. If individual keys are sticking or unresponsive, clean around the keycaps using compressed air or a soft brush to remove dust and debris. For non-mechanical keyboards like the MX Keys S, avoid removing keycaps as this may cause damage; if cleaning doesn't help, a full reset Logitech mx keys keyboard can clear persistent connection or pairing issues.
