Asurion Experts make sense of complex tech. Whether you want advice on choosing a home security system or understanding the benefits of smart home systems, we can help. Here's how to reset an ADT alarm panel in a few simple steps.

Reasons you might need to reset your ADT alarm

An ADT alarm reset might be necessary after a power outage, battery replacement, or alarm event. In these scenarios, the panel may display an error message or alert. Resetting the panel restores it to its full functionality.

How to reset the ADT alarm panel

ADT provides homeowners with a code used to reset their devices. You can find the code in your ADT manual if you don't know it outright. 

Resetting after battery replacement

Many ADT systems run on batteries. When the battery power gets low, you'll see an error message on the ADT panel. That's the sign to replace it. 

After inserting and securing a fresh battery within the panel, close the device. Verify the device doesn't display a low battery error. Wait for it to prompt you for the key combination. The combination typically includes your security code and another button associated with the device type.
