    Sounds like someone set a Firmware Password or there is a hardware issue.

    Booting From An OS X Installer Disc

    1. Insert OS X Installer Disc into the optical drive.
    2. Restart the computer.
    3. Immediately after the chime press and hold down the "C" key.
    4. Release the key when the spinning gear below the dark gray Apple logo appears.
    5. Wait for installer to finish loading.


    What happens, precisely?

    OK. Try resetting the PRAM and resetting the SMC. Try again with install DVD. Be sure to wait several minutes as the installer is slow to load from optical media.

    The previous methods do all the resetting you can do. Since they occur before anything else there should be nothing but gray screen during the PRAM reset. Be sure you've followed the instructions properly.

    Otherwise I can only suggest you take it in for repair.

    If it looks like this, Kappy is right and your firmware is locked.  You need to use the password used when configuring this feature in Open Firmware.

     

    To force remove password protection, change the amount of RAM by adding or removing DIMMs then reset the PRAM three times.

    I have tried to reset my pram by pressing and holding command+option+p+r and by removing one of my memory sticks and same combo and this is the only screen I get.

    This is for those of you who've tried to find out how to do away with the gray padlock of death.  You have to install the original OS disc that came with your computer. Insert it and go to Mac installer, under Disk Utilities to the drop down menu. Then go to about the fourth one down marked Firmware Password. When you do, it just turn off the password portion of it and you won't need to enter any password the next time you install or reboot from your DVD/CD disc. But just be aware that in doing this, anyone can login into your OS. Hope it helps.  ~Kathryne
