Honeywell VISTA: Resetting or Changing the Master Code

Our video tutorial has two ways to reset the Master Code for your Honeywell VISTA alarm system should the code ever become lost or compromised.

The Master Code for your security system is the key to daily operation. If your code becomes compromised, the security of the entire alarm system is at risk. This complete video guide shows you how to change and reset the Master Code of the Honeywell VISTA.

Don’t be embarrassed if you don’t quite understand the difference between the Master Code and the Installer Code. Many Do-it-Yourselfers are confused at first. The Master Code is designed for daily end user operations such as arming, disarming and setting alarm zones.

The Installer Code lets you access more technical, system-specific info like daily logs, maintenance operations and system resets. As a do-it-yourselfer, you’ll have a need to use both codes, because you’re both installer and user.

The system ships with default Master and Installer codes. The default Master Code is 1234 and Installer is 4122. You’ll need the default codes for initial installation but then you’ll want to change them to something personal.

There are two ways to reset the Master Code. The first way is if you know the current Master Code. This could be a code you created previously or the default code.

As the video shows, you first enter the Master Code into the system. Then you push 02. Two is the slot number for the Master User, which is you (and anyone else who knows the Master Code). Then you enter the new code you want to use. Finally, you confirm that new code by entering it a second time.

If the system accepts the code you’ll hear a short beep. If the code is invalid, you’ll hear a longer error tone. The video has clear examples of both so you can make sure your code was accepted.

The main reason a code would not be accepted is if it were already in use by the system. For example, you can’t have the same Master Code as Installer Code or any sub-user code.

The second way to reset the code is to access Programming by entering the Installer Code. Within the installer menu is the option to reset the Master Code to the default. You don’t need to know the Master Code you’re resetting.

Using the Installer Code to reset the Master Code is a great solution if you’ve forgotten the Master Code or it was changed without your knowledge. But the feature also illustrates the importance of changing your Installer Code. If someone knew the default Installer Code – info which isn’t hard to find – they can wipe out your Master Code and access your entire alarm system.

Fortunately, regular system users will never have a need for the Installer Code, so you can keep it pretty secure. A secure Installation Code combined with a regularly changed Master Code is a powerful combination for your home alarm system.

What if I forgot the code? Because I just moved into a house and the old homeowners just left the system here. I do not know the code.

Where is the video for the vista 21iP that shows how to reset the Master Code using the Installer Menu (when you forget the Master Code)?

[denisedalrymple]

What happens if the previous homeowner didn’t give me the master code and the installer code doesn’t work either? Asking because I keep getting a system low batt message with random constant beeping, and no idea where the master battery is within the house.

You may have to play this back a few times but if you just do what the guy says to do it works!

[vishaljanani]

I do not know the master code as the previous owner didn't give one. Can you advise how to reset that to default?

[imranmaqbool]

Sir what should I do when I get a message.. Alarm 01 down motion

Where is the other video showing how to get into an existing system / change the master code if you inherited it after moving into a house?

Hello, I’m praying I can get an answer from someone somewhere. I’m going to make my long story very short. Wife and I bought a house. The owners have since passed. We have an alarm but not a soul knows the master code somehow the alarm was armed when trying to stop the beeping that happens all the time. I don’t understand what I could have possibly done besides hold down the exit button to stop the beeping as I’ve always done. I don’t want to to this thing out of the wall. It’s so hardwired to the doors abba is integrated into the smoke alarm. Can you please help me. Our point me in the direction to get this resolved. PLEASE! For the love of God.
I found a metal box with a backup battery. The board says NX-6. The keypad says safeguard security on the front. It has fire emergency and police buttons on the left. Stay exit bypass and cancel on the right. Numerical keypad buttons in the middle. Armed instant and ready on the screen on the left.
