Zusammenfassung:	The present disclosure is directed to an electronic deadbolt control system including a deadbolt configured to extend or retract between a locked position and an unlocked position, respectively. An output shaft connected between a final gear and the deadbolt is configured to transmit an actuation force to the deadbolt from an electric motor. A first magnet and a second magnet are associated with the final gear to define a home position for either a left hand deadbolt or a right hand deadbolt. A cam is positioned on the output shaft to engage with a switch such that, in combination with a threshold current motor output, the control system determines whether the deadbolt is in an extended position or a retracted position. A thumb-turn shaft is disengaged from the final gear in the home position to permit manual actuation of a thumb-turn.
