Open Sesame! Keyless door entry systems for an apartment complex? [more inside]

My 8-yr-old house has Schlage doorknobs, of the type with a lock in the middle of the knob. When the lever in the middle of the knob is pushed and turned, door is locked. (Vertical position = unlocked, horizontal = locked) When you turn the knob, even if the door is locked, you can still get out (good for emergencies). Problem is, when you do that, the door does not unlock permanently. So visitors are sure to lock themselves out! In other words, it works like a hotel room door. Is there a way to change the default setting, such that even if you lock the knob, once you turn the knob to open the door the latch UNLOCKS? (I tried to find a picture online but cannot find one)

What is the use of double locks? Not two separate lock, just the kind of lock that you can turn once (which locks the door) and then another time, in the same direction (which locks the door... more?). [more inside]
