How Do I Change the Master Code for a VISTA-15P, 20P or 21iP Using the Honeywell Home Tuxedo?

You can change the Master Code for a VISTA-15P, 20P or 21iP using the Honeywell Home Tuxedo by accessing the keypad's Console Mode and then entering the command to change the code. By doing this, the new code will be applied across the entire Honeywell VISTA, rather than just for the Tuxedo.


When you put the Tuxedo into Console Mode, you can operate the device in the same manner as an Alphanumeric Keypad. This is useful for programming the VISTA System through the Tuxedo Keypad. Once the Tuxedo is in Console Mode, you can enter the necessary command to change the system's Master Code. By changing the Master Code in this manner the change will be applied across the entire VISTA System.

It is important to note that you cannot change the Master Code from the Users Menu of the Tuxedo Keypad. This is because only user code slots 03 through 49 can be changed from that menu. Since the Master Code is hard-coded to slot 02, it cannot be changed in this manner. That is why you need to use Console Mode if you want to change the Master Code for a VISTA System using a Resideo Tuxedo Keypad.

Complete the following steps to change the VISTA System Master Code by using Console Mode on a Tuxedo Keypad:

1. Access Console Mode. From the main screen of the Tuxedo Keypad, choose Security. Then press the circle with the three (3) dots inside of it (More Choices). Choose Console Mode. You will enter Console Mode, and there will be an emulated Alphanumeric Keypad for entering commands.

2. Change the code. The Master Code on a Honeywell VISTA System is hard-coded to slot 02. Codes on the system are four (4) digits in length. To change the code, enter the following command:

[Current Master Code] + [8] + [02] + [New Master Code] + [New Master Code Again]

The default Master Code for a VISTA system is 1234, so use that code as the Current Master Code if it has never been changed before. The new code should also be four digits in length. Make sure to choose a code that you can easily remember, but will also be difficult for others to guess. The Tuxedo will beep to confirm the change.

3. Return home. Press the picture of the house in the upper-right corner to return home. The change to the Master Code will be automatically saved.
