To change your master code:

Enter the following procedure without any pauses between keystrokes:

Enter Current Master Code + Code Key (8) + User Number (02) + New Master Code (4 Digits) + New Master Code

To change other codes:

Enter Master Code + Code Key (8) + User Number (2 Digits) + New Code (4 Digits)

NOTE: If you have an older ADEMCO control panel (4110DL, 4110XM, VISTA-10SE) use a single digit user number (i.e. 2 for master etc.)
