Aside from all the other advice you've been given I should point out
that the Ademco product you're using "forgets" the digits you've pressed
if you allow more than about two seconds between button pushes.  If
you've managed to change the codes in other locations, chances are you
have the "master" or "manager" code.

Hope this helps.
