How can I reprogram my Kenmore #721.8822880?

CHILD LOCK
Your oven has a child lockout feature that shuts off the microwave power until you cancel the lockout.
To set the Child Lock:
I. Touch STOP/CLEAR.
2. Touch and hold '*0"for more than 2 seconds or until the "L" appears at the left in the display window.
In this condition, the oven will not operate. If you touch START, "Err" will display and you will hear one
long beep.
To Cancel the Child Lock:
1. Touch STOP/CLEAR.
2. Touch and hold "0" for more than 2 seconds or until the "L" disappears from the display window.
The oven is now ready to use.
