Hi,
This is my first time on the Arduino forum and new to building projects. I have however managed to build the RFID door lock, one of the projects in "The TAB Book of Arduino Projects". However on page 57 of the book it tells you to install sketch ch_05_rfid. Can someone please tell me where to find this sketch. I have searched all the relevant sites without success including this site.
Probably to an experienced Arduino user I am asking a silly basic question but at 76 perhaps I'm allowed.
Hoping for a positive reply.

Your google skills need an update 
google simon monk ch_05_rfid gives you e.g. github simonmonk/tab_arduino
with (what looks like) all the codes.
