A smart door lock includes a main housing configured to be disposed interior of a standard bore hole of a door. An outer housing is disposed exterior of a secure environment and electrically and mechanically connected to the main housing via conductive prongs. An inner housing is disposed interior of the secure environment. A rotating member is magnetically attached to the inner housing. A deadbolt within a bolt housing transitions between a locked position and an unlocked position in response to the door lock detecting a user device within a wireless communication range, detecting a touch on a sensor of the outer housing, or rotation of the rotating member. The outer housing includes leakage regions to facilitate transmission of wireless signals to the main housing.
