A locking/unlocking device usable with a door operator having a tapered shaft including a first element possessing a surface with a recess. A second element also includes a surface such that a fastener removably holds the first element to the second element to form a unit. The unit includes an aperture formed by the recess to at least partially circumscribe the tapered shaft of the door opener. A moveable foot located on the unit is driven against the door to allow the door operator to be positioned between a locked and unlocked orientation.
