I have an XTi panel that was originally purchased through SafeMart and Livewatch Security. I have a door sensor that seems to be bad so I ordered a new one. However when I go into programming the installer code 4321 does not work. I've also tried 1960, 2508, 2545, 2915 and 6529 that I have seen in other posts.
Is there a way this can be reset or am I going to have to reset the panel to factory default?
