Some keys on keyboard (Alienware 17 R4) not working?

Hello, I just received my new Alienware and was shocked when i noticed that some keys are not working at all. 4, p, f and the Home button do not do anything. I already tried those buttons in BIOS and they did not work there either, so I am confident this is a Hardware issue. Anyone know an easy way to fix this, or do I need to send the machine back and wait for Dell to send a new one :/?

Thank you!
