Setting up firmware password protection in Mac OS X

 

From the linked article (bold added):

This implies that there is a way that Apple can disable it by taking the machine apart. Take it in and have it disabled. They will probably charge you money for this unless you buy apple care 90 days before you tell apple about the problem.

Next time use filevault2 as its more secure anyways and also easier to reinstall if (when) you forget your password again.

 

Try this:

1) Shut down the computer
2) Remove one of the two sticks of RAM in it (or if it only has one add one)
3) Reboot holding down Command-Option-P-R until you hear the startup sound twice (twice, not once).

I have heard this removes the firmware password...

 

Are you sure there's a firmware password?

restart the computer holding 'alt', and see if it asks you for a password.

and if it does, perhaps you can contact the person you bought it from, and ask him what it might be?(don't try to guess)

 

This should work for that MacBook. Starting with, I believe, the 2010 models, it won't work anymore, however. Apple now has to send a service center a special single-use bootable disk that will unlock and allow them to reset the firmware password on that specific machine. Quite secure, although kind of a pain.
