ADT is a reputable company that deals with home security systems, and it is one of the leading brands. It is equipped with some sophisticated features and ensures the monitoring experience is precise in keeping your home secure from intruders and other risks. But as time passes, one may want to change the passcode on one’s ADT alarm or the personal identification number PIN. It is advisable to change the code regularly to avoid code getting outdated or vulnerable to outside influences as a result of frequent usage or sharing. Thankfully, altering the code to your ADT alarm is not a difficult affair at all and can be accomplished in a short amount of time. If you are not aware of how to go about it, then follow this simple guide to the end.

Before You Begin Make Sure That You Could Touch the Keypad

First, ensure that you can navigate to and recognize the ADT alarm system keypad. The alphanumeric keypad you have will depend on the type of ADT system that has been introduced in your home, and that is either attached to the main alarm panel, which is usually placed in the closet, basement, or garage, or fixed on the wall in a convenient area. If you have misplaced your keypad or are not sure where it is, consult the records you received during the installation of ADT to be informed of the model and location, or call the ADT team. It means that you will not have a way of changing the code other than having direct access to the working keypad.

Locate Your Master Code

You will also need your previous ADT alarm system’s master code to complete this process of changing the four-digit PIN code. You can have more than one code for the arm/disarm feature of your system, but only the master code offers the option to view system functions such as code modification. If you have forgotten or lost your ADT master code, you have to contact ADT customer support and they will help you to validate your identity and then have your master code to be reset.

Make sure that you still have the new code on hand

When confirmed, the user is to select a recent secure master code of four to six digits apart from their old ADT alarm PIN. It is also important to avoid sequences that anyone might guess or significant numbers such as birthdays etc. It is wise, before proceeding with the steps mentioned above, to have the new master PIN code with you.

Follow When Resetting an ADT Alarm Code Disarm the System

If the ADT system is currently in the Armed state, then enter your current master code to fully Disarm the alarm. Any code, however, cannot be edited unless all disarming in the system is done. Wait for a beep sound and ensure that the READY light comes on to indicate that the machine is ready for use.

Initiate Programming Mode

With the keypad ready, you can now start programming mode to change the master code:

Type in the master code that you have at the moment Volume control position is situated under the number two button and there should be one press on this key. Enter zero Please another master code that you have been using before

Key in your password with the keypad and wait for three beeps, then the PROGRAM light is on. This has now put the program into programming mode so that modifications can be made as needed.

Please input your new master pin with four to six digits. Please, re-enter your new PIN so that the system can confirm that you are indeed the owner of the account.

The most common is ID but your ADT installer may have used a different ID during the initial setting up process. Look at the documents that you signed when you signed up for ADT or you could talk to the personnel at ADT.

Save and Exit Programming

When the new PIN is input and entered again, it becomes activated for use and remains stored in the keypad. Exit the programming mode to arm or disarm the system as normal:

This is done by pressing the exit button or pound button The next line is: Please enter your NEW master code once Wait for the keypad to beep several times continuously and the voice recognition system to say ‘SYSTEM READY’ which confirms the program mode has been exited.

Test and Update Codes

As you introduce the master PIN code, do not fully rely on it at first. Turn the system on and off at least one time fully using only the keypad. Change any additional codes and combinations for the secondary alarm which were previously set using the old master. After the code has been used to disarm the ADT alarm, it should be completely removed, by erasing any written or printed documents of the code to prevent misuse.

If there are any problems with the new PIN in arming or disarming the system, return to programming mode, and go through the steps mentioned above again. Make sure that it is a new PIN of 4 to 6 digits and that the entered new PIN is correct when it is entered twice for confirmation during the change process. If needed, seek further help from an ADT representative to help you determine how to resolve any issues.

ADT Home Alarm System tips on how to maintain your alarm security

Another way of maintaining the security of the system of your home as you live in it is to ensure that you change the ADT alarm PIN from time to time. 

Never give out the PIN codes to strangers – limit the alarm’s access to only those who are permanent residents of the house and who may need to turn on or off the alarm frequently.

Do not use combinations that are easy to guess or identify with numbers close to your heart for codes - Ensure that PIN options are random to enhance safety.

Change the master code at least yearly or when a resident moves in or out - This controls the risk of old occupant system knowledge.

Do not place keypads within the sight and reach of the visitors and the public – it is advisable to place keypads in secluded areas to avoid code tampering.

Change the second code when the master code is modified – Any additional codes like associate, garage, guest, or maid should be different from that of master to avoid overrides.

Erased old alarm code references – Ensure that previous alarm code numbers, or any other related records, are disposed of or shredded to prevent future identification.

This way, effectively controlling all the ADT alarm user codes and their regular changes, your home will be one of the safest places for you and the members of your family, as well as your possessions. For any other further questions or concerns with your installed panel, keypad system, or any monitored services, you can contact a professional ADT technician.
