    Hi, I have an Ademco 6128 keypad with a Vista 10se box. The alarm is stuck in armed mode and I can't get any input when pressing the keys on the keypad. I'm guessing I should just replace the keypad with another 6128 found online.I've seen that you get the code for addressing the new keypad by holding down the 3 and the 1 within 5 seconds of powering up but I can't get the code because the old keypad won't accept any input. Is this going to be a problem when replacing with a new keypad? I've also seen that the default is 31 but my concern is, what if it isn't the default. Any help would be greatly appreciated.

    before you try any replacement, i want you to try this:
    1.power down the panel.
    2.re-work the connections of the keypad with the panel. -ve of keypad to terminal 4 on the panel. +ve of keypad to 5. DI/G/green to 6. DO/Y/yellow to 7. make sure none of the wires are shorting out each other.
    3. power up the panel with * and # held down, use ac first. if everything is good, this should take you in programming.
    4. if you are in programming, check installer code by hitting #20. then come out of programming by hitting *99
    5. out of programming, you will see panel will be disarmed. program yourself a master code by hitting <Installer code> + 82 + <new master code>

    if all goes well then your panel is ready to go.

    Thanks for the advice. I connected everything then powered up. I held down the *# and got a flashing code 20 then entire lcd lettering lit up. Now screen shows NO AC with two right pointing arrows, one above the other.

    that looks like data corruption. try changing the wiring and see if it solves it, otherwise replace the keypad.

    Same result. One last thing, any advice on addressing the new keypad without being able to get the code with old keypad.

    You should not need to address this panel because you cannot change it from 31, that being said  try only hooking up the positive  (red ) and negative (black )  to the key pad press 1+3 after power up your address should show up , hit 00 then 31  then  *  to  exit.   If you get a new keypad do this to program it to 31 , all vista 10, 20  I believe are non addressable panels default is 31 non adressable
