1. A door lock comprising:
a driveshaft operatively couplable to a door lock bolt, the driveshaft being rotatable over a driveshaft range greater than 360 degrees between a first end position to a second end position to move the door lock bolt between an extended position and a retracted position;
a transmission coupled to the driveshaft; and
a sensor gear operatively connected with the driveshaft by the transmission, wherein the transmission reduces rotation of the sensor gear to a sensor gear range of no greater than 360 degrees when the driveshaft is rotated over the driveshaft range; and
a sensor configured to detect a rotational position of the sensor gear corresponding to rotation of the sensor gear to a position along the sensor gear range.
