1. A movable barrier operator comprising:
a body;
a motor supported by the body and including a rotatable shaft;
a rotatable drive supported by the body and configured to be connected to an elongate driven member; and
a lockable transmission connecting the motor to the rotatable drive, the lockable transmission having: an unlocked configuration that permits the rotatable drive to rotate relative to the body to drive the driven member; and a locked configuration that secures the rotatable drive to the body and fixes the rotatable drive against rotation relative to the body,
the lockable transmission configured to shift from the unlocked configuration to the locked configuration in response to a torque applied to the rotatable drive exceeding a predetermined threshold.
