When I turn on the mac, it goes to the loading screen with the progress bar below the apple logo, and it never finishes loading. That happened after OS upgrade.
I've tried using keyboard shortcuts but none of them seem to work.
Probably mac doesn't see keyboard, because batteries were changed.
iMac 27″, macOS 10.15
Not including exactly which keyboard shortcuts you’ve tried I can only suggest trying a safe boot How to use safe mode on your Mac - Apple Support
If that doesn’t work go through the steps listed here If your Mac doesn't start up all the way - Apple Support
