With the reset button held down, reinsert the battery to reapply power. Keep the button held down for another 30 seconds. You will know that the reset is going through because the keypad will be flashing. After 30 seconds, you can then release the reset button. Wait for the startup sound before removing the batteries to reattach to the door.
Reassemble the lock. Make sure that all the connections are nice and sealed. Remember, performing a factory reset will have the lock behave as if it were powered on for the first time ever, which means you will now have to set the Master Code
