9800 broken pins on NVM chip

[AllanK]

I've fitted a new keypad to my 9800 scantronic alarm as some of the keys had stopped working at all.
To cut a long story short following lots of advice from the forum I got to the point where I had concluded that my engineer code isn't the default and wanted to reset the system.
Taking out the NVM chip as part of that process revealed that either by me or already some of the pins are broken and my keypad is not displaying anything. I looked up the NVM chip by the code and found it was a sharp eeprom chip and promptly ordered one which is on the way but I'm wondering if a standard chip is no good as the chip may be programmed specifically for the 9800. Does anyone know if I can just fit this replacement part and any other advice would be useful.

I would suspect a replacement chip may be no good unless that one was only used for storing settings. It probably originally had the default settings on it so a new 'blank' one won't suffice, but I may be wrong.
