Make sure the system is disarmed. Press "9" to enter the "Program" menu.
Enter your 5-digit master alarm code. All lights on the control panel will blink.
Press the number of the access code you want to change then the "#" key. NuTech alarm systems can hold up to nine access codes for various family members. For example, press "1" then "#."
Enter a new 5 digit code. If you want to use a shorter code, add enough zeros to the end to make it 5 digits long. These extra zeros will not be included in your code. For example "76" would be entered as "76000."
Wait as the alarm system exits programming mode. The code is now ready to use.
