Like many other people I moved into a new home with Concord 4 and I don't know any of the codes. We do not have service with it but my wife likes the notifications when you open doors and windows. Somehow the system got put in STAY status and cant turn it off so I just have the system unplugged now. I have contacted the previous owner and they don't remember there codes. I have tried many other solutions suggested on the forums with no luck. I recently got an EEPROM reader and set everything up. I have inserted the EEPROM the way everyone said and read the data. Unfortunately when I pull it up in a hex reader i don't have 0x3E2 or 0x3E5. After not being able to find this I read the EEPROM in all 4 positions on from the reader and still no luck. It is a 24C256 EEPROM. Any other suggestions?
I have uploaded the read file.
