Sorry, I didn't take any pics because I assumed someone here had likely done this swap already. As far as removing the keypad goes, it is a relatively simple process;
1) tape off the door on either end of keypad to protect the paint
2) pry up either end of the keypad while simultaneously pushing the keypad towards the opposite side (there is a spring steel clip on each end that holds the keypad in place)
3) lift out the keypad and disconnect the wire harness connector
