I have two extra of these, is there a way to reset the master Installer Code? Or is the master password somehow BIOS locked? I don't want to throw these away if I don't have to, but they are useless of course if they can't be unlocked! Any help appreciated. PS *,# upon power up then entering a new master code doesn't seem to work on either panel. I know for sure one came out of a Monitronics system,the other has identical numbers on it and the same behavior).....
