I have a 2010 Ford Taurus keyless remote and I just replaced the outside keyless entry keypad and there's no power to it?

My question is does anyone have and idea why there's no power to the outside keypad? Have anyone experienced this problem? Beside taking it to another dealership can anyone help me out? Oh yeah by the way I went to the Ford Dealership to get the part replaced, but he wanted to charge my an arm and a leg to put in the code.
No rude comments please? And thanks in advance?

I think for keys you can only go thru a dealership, maybe try phoning another dealership in your area if you have more than one.
