Determining right or left hand side door installation

A method of determining right or hand side door installation, comprising:

• rotating a drive shaft of a door lock mechanism with a bolt in a clock wise direction or a counter-clock wise direction until there is sufficient extension of the bolt to determine a status of a lock position of an associated door at a dwelling, the door lock mechanism including a position sensing device, the position sensing device sensing a position of the drive shaft and assists in locking and unlocking the bolt;
• querying a user of the door lock when the drive shaft is at an end point, wherein the associated door is right hand in-swing, or left hand outswing, installed when the door locks with clock wise rotation and is left hand in-swing, or right hand outswing installed when the door locks with counter clock wise rotation;
• and
• wherein a mobile device of a user occupant of the dwelling is in communication with the door lock mechanism to provide locking or unlocking of the door, and a non-user occupant third party is allowed controlled access to the dwelling with the non-user occupant third party mobile device when the user occupant grants access rights to the non-user occupant third party, the user being the user occupant of the dwelling or the non-user occupant third party.
