Task Analysis:
1. Find a specific place for the key to be located, such as a hook or on a specific piece of furniture. Practice leading the student away from the designated location for the key storage and asking him or her, "(Name), please go and get your key." Continue this exercise, delaying the time (up to 3 minutes) from placement on the hook to finding the key until no guidance other than the verbal request is needed.
2. After showing the student the specific key that will unlock the door to be used in training, capitalize on the student's discriminatory skills (see pre-requisite ADT 5) by placing a variety of keys before the student and asking him or her to select the specific key that was shown. If problems occur, you may need to color code or otherwise identify the specific key.
3. Using the lock sets, physically guide the student through the process of inserting the key into the lock.
4. Continue Step 3, adding the turning of the key.
5. Continue Step 4, adding the removal of the key.
6. Transfer the skills learned in Steps 3 through 5 to the actual door to be used.
7. Reduce all physical guidance to verbal and gestural step-by-step requests.
8. Reduce all prompting until just the total-task request, "(Name), please un-lock the door," results in the necessary action described in the objective.
9. Reverse the training of Step 1 to have the student relocate the key to its assigned placement.
10. Although the objective is technically met in Step 9, continue the training by teaching the "locking concept" based on the specific lock, whether or not a key is needed for that activity.
