a1 locksmith advised me to To install batteries, remove cover between knob and keypad.Unlock door with the override key provided in the plastic bag attached to the owner's manual, and open the door using the knob. Remove battery cover located on the inside back of the door by sliding to the right. Insert the four batteries as indicated. Replace the battery cover.

I finally get to provide a solution for something!!!

Open door with the key, press the reset button hiding on the hinge side of the door mechanism, you will hear a beep. You don't have to have the key in or out. Enter your new code, and press A. Then lock it and test your code.

Use paperclip to push in pin size hole below keyboard and then slide panel to right. Battery box is right there. Replace batteries and then was already to accept code.
