The fact that you can go from "stay" to "away" shows that the system is
accepting the code you are entering.   I assume you have tried disarming
the system from all the other keypads.  I'm also assuming the "1" key beeps
when you push it, indicating the keypad is recognizing that you pushed that
button (in older systems. the "1" key will sometimes work intermittently).

My next step would be to disconnect all the keypad wiring from the panel,
then connect one keypad directly to the panel and see if that works.  Set
the address on that keypad to "00."
