How to Reset My ADT Passcode So I May Arm My Alarm Systemby Kimberly TurtenwaldUpdated August 30, 2017
The ADT security code allows users to arm and disarm the security system as needed. Each person in the household can have his own security code so that the code is easier for each person to remember. Many of the alarm system models also offer a duress code, which should be used in situations where you are forced to disarm your alarm. You can change any of the codes within your system as long as you remember the main access code.
Enter your four-digit master security code into the system to access the administrator functions in your security system.
Press the "Options" and "3" keys, "8" or "Code" key to let the system know you want to change a code. On a BHS-3000C model with premium keypad, press the "Options" key until "auxiliary codes" appears on the display. In general, he keys you must press depends on the model of your keypad.
If your keypad displays the phrase "Enter Master Code" or flashes the "Enter Code" light, enter the master security code.
Enter the number of the user for which you want to change the code. Some models require a two-digit number, while others require only a one-digit number. Check your owner's manual to check which user numbers are reserved for special users, such as the duress and babysitter numbers.
Use the keypad to enter the new four-digit code. The keypad will beep when the new security code is programmed.
Test using the new code to arm and disarm the system to make sure it works.
Check your specific model's user manual for variations, especially if you own an older ADT security system.
Avoid using a code that is easy for someone else to guess.
