Default Macbook pro startup combo keys won't work

Ok I was asked to do a password reset on a mac figured it would take 2 seconds with a boot disc. However when I tried to boot from the disc by pressing C it wouldn't read the disc it seemed like it would try and fail, so I tried my disc same thing. Figured it was a faulty superdrive replaced that and it's doing the same thing. Now I'm realizing that none of the startup keys are working.
Option-Command-P-R
C for startup CD
Option
Shift for safemode
Command V

Nothing works, it always goes straight into the login screen. I even tried command+option O + F to see if that somehow set a firmware password that doesn't work either. The keyboard types when trying to put in a password just fine. I even tried an external mac keyboard into the usb ports. Any ideas??

More than likely liquid spill into keyboard and a key or keys are stuck/triggered so no other key commands work. Probably why they figured it just needed a password reset? Disconnect built in keyboard then try with usb keyboard to verify.

Out of curiosity why would the keyboard work fine when the logon screen comes up?

Depends on which keys are affected. If you go into system prefs/international or system prefs/language and text (depending on which version of OSX) and then go to input sources. There should be a check box for keyboard viewer. Check it on then on the menu bar at the right, near the clock there will be a new keyboard viewer icon. Click on it and select "show keyboard viewer" then a keyboard GUI map will show on the screen and show any key or keys pressed.
