Forging the code on an ADT alarm system is a simple process that will only take you a few minutes of your valuable time. Thus, having one’s codes for a home security system makes it easier to safeguard one’s house and at the same time guarantee the safety of your home since it is accessible only to the intended individuals. Below are instructions to help you change the ADT alarm master code and the other user codes:

Things You'll Need:

  • The master code for your current ADT security alarm system
  • Master code &/or user codes you wish to program

Change Your ADT Alarm Master Code: 

Step 1: Log into Your ADT Pulse Account The first step in accessing your account is to log into ADT Pulse, which is the main page for the service. If you have the ADT Pulse app, you can manage your alarm codes using your mobile phone application. On the face of it, open the application, enter the user name and password, and proceed to the tab that provides an option to alter the master PIN code. In case you have lost access or cannot use the mobile app, you can change your master code through the keypad.

Step 2: Enter the current master code of your Honda vehicle. 〈Go to your ADT alarm system keypad and then enter your present master code. 

Step 3: switch on the television and go to the programming mode following the next steps below. Then press # or Pound as we often refer to it in the United States. You have now been able to get through to the programming section of your system by keying in *0# which will enable you to change your settings.

Step 4: Reset to the Master Code Second, press the number “1” for the master code change. Then input the 4-digit number you wish to use for your new master code. When done press the * button found at the bottom of the phone. This will store your new master PIN into the system.

Step 5: This step involves moving out of programming mode. Lastly, press 99 and press the * button on your phone while you are still on the call. This instructs your system that you want to stop the program mode. Congratulations, we have updated your new master code for you.

How to Add, Modify, or Delete Your ADT Alarm User Codes

Regarding the master code that allows arming/ disarming of the system as well as changing any other setting, your ADT system also offers an option to set up individual users’ codes. It enables you to define unique user access levels that can be personalized. Here is how to add, modify or remove secondary codes: Here is how to add, modify or remove secondary codes:

Add New User Codes

Step 1: With the remote control still on, repeat steps 1-3 above and place the remote into programming mode. Step 2: If the user code addition is the purpose of the call the person will be instructed to press “2” Step 3: You should type in the new 4-digit user code in the keypad. Step 4: Assign the user code a number from 2 to 9 across the entire row or column where it is located. This number refers to the authority of the vehicles. Step 5: The star (*) button should be pressed to set the new user code.

The numbered authority levels correspond to the following privileges: 

Level 2: Dislocate your home security only and change user IDs Master code: Provides the access level that can be provided by the Master code 

Level 3: Arm/disarm and bypass areas

Level 4: Arm & disarm, disable/enable areas

Change Existing User Code

First of all, you need to get into the programming mode, for that, you should input your Master Code. Step 2: If the user has a PIN, then he or she will be prompted to press “3” to edit a user code. Step 3: To change the code entered by the user then the user should input the number (2-9) corresponding to the entered code that he wants to change. Step 4: Alphanumeric 4-digit user new code Step 5: Press * to Save the change that has been done

The user number will remain the same, however, a new code will be introduced which will be memorized and used to arm and disarm the system.

When programming new codes for your Alarm System keypad, keep in mind these recommendations: 

  • It is also important not to use certain strings like phone numbers, addresses, or birthdays that are quite easy to guess.
  • It is good to change your Alarm codes at least once every year if you want to improve security.
  • It is preferred that you memorize the Master Code instead of writing it down so that it is easily accessible to anyone.
  • When inputting Master and User codes, ensure it is four digits or more

Therefore, it is recommended that you keep your alarm system user codes more manageable so that various levels of system access can not only be provided to all family members, home caretakers, or anyone who may be using the ADT system but also be controlled effectively. Simply changing each of the ADT security codes once in a while takes no more than five minutes and improves the security of your home.
