2000 Navigator: ignition key question

2000 Navigator: ignition key question
I purchased a blank from EBAY and their instructions are pretty simple saying I need two already programmed keys to program a new one.

My questions are:

Has anyone don’t this – any problems?
What actually happens if you put a non-programmed key into the ignition?

Thanks
Lou

I'll answer it myself.

It worked. I bought the key for 11.50 (including shipping) from ebay. Took it to Lowe's - they cut it for free. Follow the instuctions on the key web site and now I have an extra key.

You didn't mention what happens when you try to use it un-programmed.......

I did it in my 1998 it was a breeze. Very simple.
