I would restore the iMac and change your iCloud password.

It’s asking for the keyboard to be connected.

That translation isn't quite right. It means "The wrong button has been pressed. Quick press the power button on the back of the Mac twice to safely connect your keyboard." I think the meaning of quick press is to press and release quickly, rather than holding down the power button.
