Hi karennayak, My name is Jeremy, a Windows Independent Adviser. I'll be happy to help you out today. Let’s see what I can do.
Is your keyboard still working now? or you have encountered a problem while trying to change the space bar key and you can't use the keyboard at all?
if it's not working at all, you can reset it and try to change the spacebar keys again
- Right-click on the start menu and select "Device Manager"
- Expand the "keyboards" and right-click the HID keyboard and select uninstall
- Follow on-screen instruction and restart your device
- After the restart, Go back to Device Manager and click on "Action" then select "scan for hardware changes" it will reinstall your keyboard driver
You may use this method to assign other keys for your spacebar, please visit the link below
