The Arrow Lock MK11DD-10B-CS Entrance, Office Knob Lock is great for commercial applications that require accessibility certifications, like an entrance/office setting. It has a deadlocking latchbolt, operated by a knob from either side, except when the outside knob is locked. This can be done by pushing the turn button inside. A paired key outside releases the turn button, unlocking the outside knob. The inside turnbutton is manually operated to unlock the outside knob, and the inside knob is always operated by a latchbolt.
