So I got a copy of the indtructions from a local sears store.
You just enter whatever 4 digit code you want, then hold down the enter key.
the keypad lights will flash as long as the enter key is held. ?Have somone push the yellow, or green button on the garage door motor. The button should be labled "smart" button. when the smart button is pressed, the keypad should stop blinking.
the new code will now open the garage door.
