A system is provided that may include a motor, a locking mechanism, an encoder, and a controller. The motor may rotate a shaft to move a door between an open position and a closed position. The locking mechanism may alternate between a locked and an unlocked position. The locking mechanism may retain the door in the closed position responsive to the locking mechanism being in the locked position and may allow the door to move to the open position responsive to the locking mechanism being in the unlocked position. The encoder may be coupled with the motor and may determine one or more of movement, a speed, or a direction the motor moves. The controller may receive output from the encoder indicative of the one or more of the movement, the speed, or the direction the motor moves to determine a position of the locking mechanism.
