Not so surprised. Being a good clerk at HD is not the easiest job, but even if he stays in the door hardware section for a long time, someone who can learn all the features of all the locks really ought to get a better job. For the most part they don't get to see the features, because the packages are closed.
Has anyone used those remote controlled deadlocks? They have a transmitter like a car alarm, and the one I've seen uses batteries to turn the know that opens and closes the deadlock. I don't have a great need for this, but I think I would like it. Especially if the batteries last a long time.
