Why won't the default installer code (4112800) let me access the programming menu on my Vista 20P Control Panel?

Either you accidentally changed the installer code without knowing it or you pressed (*98) the last time you tried exiting the programming menu instead of (*99). Always enter (*99) when exiting programming on your Honeywell alarm keypad.


To access the programming mode from here, you must disconnect the Vista 20P's A/C transformer plug, then remove the red and black leads from the backup battery. Wait 15 seconds before reconnecting the battery and A/C transformer plug, in that order. While the system is booting up (in the first 60 seconds), press and hold (*) and (#). The number (20) will be displayed. You are now in programming mode.
