The 9427 is the KeyPad number, not the control panel, do you know the Control Panel number?
I suspect it might be a 9448, the most common that this keypad goes with, two sorts, old & new style, here's both
CODE CHANGES
NEW style goes:
(6) (enter) old code (????) old code (????)* new code (????) (enter) 2 bleeps
* old code here means which of the two existing codes you want to change
OLD style goes:
(6) (enter) old code (????) new code (????) (enter) 2 bleeps
Good luck
