Hello people, my name is Lucio, I have an alarm from years ago mark alonso a2k4 pc777 that the keyboard is already wrong ... not all the keys but obviously the ones I use the most ... my idea was to be able to change the code of 4 income numbers to use those that do walk ... is understood? the 8 and 9 are perfect for me to say ... good to be able to make the password 8989 and voila .... Because supposedly keyboards are gone ... the others are walking but I have to press them almost to pineapples. The problem is that I don't have the installer code ... what do I do ??? My alarm has zone 1 the entrance door, zone 2 the living area 3 the barbecue, zone 4 kitchen, zone 5 room, and I have internal and external siren. Can someone help me? A million thanks.
