an interior cover housing the interior assembly;
a turnpiece extending through an opening of the interior cover;
a stem connected to both the turnpiece and an interior driver, the stem dimensioned to receive the turnpiece, wherein the interior driver is operably connected with the latch assembly; and
a mounting bracket including a plate portion defining a pass-through dimensioned to receive the wiring harness and a plurality of spaced-apart tabs extending transversely from the longitudinal axis of the interior assembly, wherein the interior assembly includes threaded openings correspondingly positioned with openings in the plurality of tabs for connecting the interior assembly to the mounting bracket, and wherein at least a portion of the tabs are spaced apart on opposing sides of the longitudinal axis of the interior assembly.
4. The electronic deadbolt assembly as recited in claim 3 , wherein the interior assembly further comprises a back plate and an interior cover dimensioned to receive the back plate.
5. The electronic deadbolt assembly as recited in claim 4 , wherein at least a portion of the plurality of tabs extend between the back plate and the interior cover.
6. The electronic deadbolt assembly as recited in claim 5 , wherein the interior cover includes a plurality of threaded openings alignable with the tabs in the mounting bracket.
7. The electronic deadbolt assembly as recited in claim 6 , wherein a portion of fasteners extend through the interior cover, tabs and back plate.
8. The electronic deadbolt assembly as recited in claim 3 , wherein the stem has a generally triangular shaped cross-section.
9. The electronic deadbolt assembly as recited in claim 3 , wherein the interior assembly includes a transmission with a gear train having more than two gears.
10. The electronic deadbolt assembly as recited in claim 9 , wherein the gear train includes three gears, wherein one of the three gears operably connected with the latch assembly.
11. An electronic deadbolt comprising:
a latch assembly including a bolt movable between an extended position and a retracted position;
