Q: Delete Key not working...

I have a brand new MacBook Pro Retina (512 Gigs) and the delete key does not work anymore. I didn't realize how much I use it until it quit working...

I ran the Hardware Test and got this error:

4SNS/1/40000001:DOR-0.000

Any suggestions?

If I hold down the function key, it WILL delete to the right, which I think it what is supposed to do anyway... but no left deleting anymore....
