I have an Audiovox Model MVX-425 Cell Phone with Audiovox Model CLA-700 Cigarette Lighter Adapter that I accidentally locked.

Does anyone know the factory default three-digit code registered in the NAM to unlock it?
I am hoping it has not been changed.
I know it is very old but it could be used to call 911.
