Changing a SHARP ER-A420 Register Key

I am trying to reprogram the MDSE SBTL key to a triple zero and can’t seem to figure it out. My old sharp register had 0, 00, 000 right next to one another but this one is 0, 00, and a MDSE SBTL key. Does anyone know how to change it?

@nicolehowlin looking through the service manual ER A410 Service, as well as the programming manual ER A410 Program, it does not look like you can remap the keyboard. Take a look at those manuals and see if you can accomplish something. You have the register so it should be easier for you to try it then it is for us telling you what to check etc.
