I just moved into this house that came with a handle set that includes some kind of interconnect plate on the inside that serves to unlock the deadbolt when the knob is turned. I want to remove the entire interior side to put an August smartlock retrofit thing on the deadbolt part and install a regular door knob on the interior of the latch.
The deadbolt and latch are not connected except by a strange plate assembly behind that face plate surrounding the interior knobs. I can remove the screws of that face plate and pull it out at the top enough to rotate it about the lower knob, but can't seem to find any screws that hold that plate onto the door. The lower knob doesn't seem to have any little screws for removing it either. Is there a trick to removing the lower knob? If I could do that, I would be able to see the entire interconnect plate, and I think I could figure out how to remove it from there.
Here you can see the interconnect plate.
