courtyard and the office door is a commercial "store front" style door.
The door key is lost so I need to replace the lockset. But I am not
familiar with this kind of lock (these are not locks you find at Home
Depot). Here is a pic of the front of the door:

and here is the back side:

How can I replace this lock? What is it called?
Is there a way I can "key" this lock so that it uses the same key as my
other doors (standard residental door locks)?
Thanks,
MC
