Thanks! Keypad.h is exactly what I needed! and it tested out perfectly... Except I discovered one of my buttons were not working 
Not a total loss as I wasn't planning on using them anyway. (They were extras just in case) It was moved....
...from this
1,2,3,A
4,5,6,B
7,8,9,C
*,0,#,D
x,x,x,E
x,x,x,F
to this
1,2,3,x <-dead button
4,5,6,x
7,8,9,x
*,0,#,x
A,B,C,x
D,E,F,x
Which looks to be a better layout anyway
