Revise Eprom(M27c512) programmed for freescale CPU-MC68HC16Z1CFC18

I own and operate an industrial battery repair company, local to Colorado. I recently purchased chargers for my shop to use, with the hope that my technicians could easily change the output(voltage/current/runtime) from the display board, these chargers are capable of it..... However, you have to have a hardware key to unlock the functionality.

I would have no problem purchasing a hardware key from the Mfg., however, they went out of production over a decade ago.... These keys are not available, and the Mfg. stopped support and making replacement parts for the charger itself over 5 years ago.

I have a GQ 4x4 that I can read and write files from/to the eprom. but that is as far as I can go. I need someone who can help me remove the need for the hardware key and make the VVR/Constant current options open.
