I cant access my imac when i turn it on it will give me flashing question mark and when i go to recovery it will show up greylock so i found out is a firmware password
so i didn little research about how to reset password but there is not too many options tho!!!
i was wondering if i change hdd`s? if is going to work or no?

The firmware password is stored in the firmware. The firmware is located in a chip or series of chips on the main logic board. It is not stored on a hard drive and thusly switching hard drives will not work.

If it is a Mac that predates 2010 or 2011 (I honestly forget which off the top of my head), you can reset it by turning it off, altering the RAM configuration and then turning it back on again. If it is a Mac from 2011 or newer, then as others have said, your only option is taking it to Apple.

You will need to take it to an Apple repair center where you will be asked for proof of ownership, then they will remove that EFI password for you. You can read about it here.

Replacing the hard drive will not get around this.

Ask your friend for the password. There is no way to circumvent or change the password, other than taking it to Apple.

You can change the password if it is from 2009 (maybe 2010 too) or earlier. Your comment is correct for 2011 and newer Macs.

Did you read the article I linked in my first post in this thread? This is all clearly explained in that article.
