Did you by any chance do a search in the forum for 4x3 keypad? Me and a few other people helped one guy with a keypad, and his code is somewhere in this forum. You just need to find it.

You did a search in this forum and found nothing? Funny, because I found this. It's not 100% what you want to do but if you tweak it, it will work.
