So, this here's a creation I made almost immediately when version 1.5 came out. I know, my voice kinda sucks, there's a low framerate of 10 FPS, and it's not the most compact design, but I figured something's better than nothing.
Using hoppers, droppers, redstone and the nice new comparators, you can create a lock for a metal door. It doesn't need to be wooden or iron doors, it can be with blocks too if you know how to wire it properly, which I assume you do.
