How to Replace the Batteries in Your Home Security Devices

Equipment

Like most devices in your home, security devices run on batteries that need to be changed from time to time. When a battery is low, you will likely see a low battery message on your security panel or hear beeping.  

You have two choices, so pick whatever works best for you:

Option 1 – Schedule a Service Appointment

Make an appointment with Guardian. We’ll send a tech to your home for a service fee. Call 1.800.PROTECT (1.800.776.8328) to schedule an appointment with our professional technicians.

Option 2 – Replace the Battery Yourself

Even better, you can do it yourself! It’s easy and hassle-free! Here’s how: 

1. Identify which device has a low battery.  

2. Find out which battery is needed and order a replacement. You may need to reference your device manual. Most batteries can be bought at a local store, or we can send you one in the mail.  To place an order for a new battery, just give us a call at 1.800.PROTECT (1.800.776.8328), or you can chat with us by visiting our contact page.

3. Before getting started, log into your Guardian account here. Toggle to “My System” on the left-hand side and select “Test.” Then follow the instructions to place your system in test mode. When in test mode, your system alarms will not notify our monitoring system while you are changing the batteries. 

4. Follow the steps to replace it. Please note that battery changes generally require a couple of common household tools, like a Phillips head or flathead screwdriver. 

IMPORTANT: Don’t forget to take your system out of Test Mode when you’re finished!

How do I change the battery in my device?

I changed my device battery. Why won’t my keypad clear?

Brand new panel batteries could take some time reach full charge after they are installed. Once the battery reaches full charge, the low battery display will clear from the keypad.If you changed a device battery, reopen the device and remove the battery for 2 minutes. After you reinstall it, attempt to clear your keypad again.
