I'm looking for a lock that is operated by a keypad. It doesn't need to be super-high security, but I'm looking for a decent lock. It can be either mechanical or electronic. I don't quite have a price range yet. I've included pictures of the door it will be mounted on below. The keypad will be mounted on this side:

As you can see, it's on a fairly cheap door. The vent was poorly installed, and the door isn't perfectly square. I've recommended a new door, but that is not an option at this point in time. As you can see, the door is a little bit less than 2 inches thick.


Any suggestions are appreciated.
