Use this order to isolate whether the issue is a stuck keyboard/input setting, a Bluetooth conflict, or a Surface input driver problem:
- Turn off keyboard accessibility features.
- Go to Settings > Accessibility > Keyboard.
- Make sure Filter Keys, Sticky Keys, and Toggle Keys are Off.
- If Filter Keys is on, it can make the keyboard seem unresponsive or require unusual input behavior.
- Remove the Bluetooth keyboard and test the built-in input first.
- Go to Settings > Bluetooth & devices.
- Remove the Bluetooth keyboard.
- Turn Bluetooth off.
- Restart the Surface.
- After restart, test whether the built-in keyboard or on-screen keyboard works normally before pairing the Bluetooth keyboard again.
- Check the basics for the Bluetooth keyboard.
- Make sure the keyboard is turned on.
- Make sure it is charged or has fresh batteries.
- Turn the keyboard off, wait a few seconds, then turn it back on.
- Keep it within range of the Surface.
- If prompted for a PIN, check the device documentation or try 0000 or 1234.
- Re-pair the Bluetooth keyboard.
- If the device was paired but not connected correctly, remove it and pair it again.
- Bluetooth keyboards can be paired but not connected until needed.
- Refresh keyboard drivers.
- Open Device Manager.
- Expand Keyboards and Human Interface Devices.
- If a keyboard device shows a warning sign, uninstall it and restart.
- If a keyboard device is disabled, enable it.
- If needed, uninstall the keyboard devices and restart so Windows reinstalls them automatically.
- On Surface devices, this helps when input behavior changed after adding a Bluetooth keyboard.
- Check Bluetooth driver state if Bluetooth behavior is abnormal.
- Open Device Manager.
- Expand Bluetooth.
- Right-click the Bluetooth adapter and select Update driver > Search automatically for drivers.
- Restart if prompted.
- If the Bluetooth toggle or icon is missing or grayed out, fully shut down the PC instead of restarting: hold Shift and select Start > Power > Shut down, wait 1 minute, then power it back on.
- Check for Windows updates.
- Go to Start > Settings > Update & Security > Windows Update.
- Install available updates, then restart.
- This can restore keyboard and mouse improvements.
- Test whether the built-in keyboard works outside Windows.
- Shut down the Surface.
- Hold Volume Up, press and release Power, and keep holding Volume Up until the Surface UEFI screen appears.
- Try the keyboard there.
- If it works in UEFI, the issue is likely a Windows driver or software conflict.
- If it does not work in UEFI, the issue is more likely hardware-related.
- If the problem continues, submit a bug through Feedback Hub once input is restored.
- Include that turning on the Bluetooth keyboard opens voice typing, disables input, and may restart the Surface or open accessibility screens.
- Also include whether this started after a Windows update or after pairing the keyboard.
