How to Replace the Batteries in Your Smart Security Devices

 

Choose your device below to find out how to replace the batteries. Before you begin, check out this list to see which ones we recommend you use.


Battery replacement guides

Before you start replacing the battery, put your system in test mode using the Alarm.com app. You can find out how here. When the system is in test mode, the monitoring station won’t respond to alarms, so you can test it or perform maintenance without worrying about dispatching emergency responders.
