I bought the home with Security Ademco Vista Panel from the dealer, but the Keypad's master code is not at it's default "1234". I talked to the dealer, he gave me the Phone # of the previous owner, I tried calling, but the number wasn't subscribed like the previous owners number has been changed so. How do I get the Master code? AD2USB specific Cmd? Should I replace the chip? Or must I get a new Keypad?
I have the Keypad and AD2USB(Bridge to computer Communications).
