12 key keypad

hi all, i have a question about the keypad library...

i have a 12 key pad that only has 7 output pins, will the keypad library work with this type?... i'm at work and was curious..

keypad library info: Arduino Playground - KeypadTutorial

thanks!

Looks like the keypad is the 4x3 the tutorial mentions... so it should work just fine
