You want to put in your system disk and boot from that if you can. As you will need to hold the C or Option key to do this, I don't know how successful you will be. If you are successful, use disk utility to repair permissions & the hard disk. If the KB is not working from the disk, it likely a hardware failure.
Do you happen to have a USB keyboard handy?
As I suspected, the keys aren't registering to allow you to boot from a CD or switch the startup disk. I am going to assume that you wont be able to reset the pram or do an SMC reset either. You can try anyway...
hold Option + Command + P + R and press the power button. Hold those keys until you hear the startup chime at least 2 times.
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Hold the shift key whilst rebooting.
You can try these three things, but I'm leaning towards a hardware failure on this as it seems the KB is not functioning even prior to the OS loading.
Tried all 3 things both you and the apple representative had suggested and still no luck what so ever. The apple representative made a reservation for me at the genius bar at my local apple store and I'm anticipating the same results if not a large bill to repair whatever has been damaged to my macbook. Although my macbook pro is still in it's 1 year limited warranty status I'm wondering if it is a hardware failure, will I have to pay Apple to repair my macbook or if they'll cover it seeing as my macbook just decided to stop working all of a sudden.
