How to Replace Your ADT Door & Window Sensor Batteries
Many of your ADT devices run off of batteries. Knowing when and how to replace them is essential to maintaining a top-of-the-line security system and a protecting your house. Your door and window sensor batteries being one of them!
Let’s quickly run through when you should replace your door and window sensor batteries and how to do it properly.
When Should You Replace Your Door and Window Sensor Batteries?
The easiest way to know is a zone trouble indicator will appear on your alarm keypad, and a sensor trouble message may appear in your ADT Pulse app.
When you get these messages, you’ll want to replace your batteries as soon as possible.
Depending on your door or window contacts, they’ll either require one CR123A 3v battery or two CR2032 batteries.

How To Replace Your Batteries
When you’re going to replace your batteries, there’s one thing you’ll want to do before you start:
Set your system into test mode to avoid a false alarm.
To put your system into test mode:
- Go to MyADT.com
- Go to “My Alarm” in the dashboard
- Go to System Management
- Then go to “Test System” and place the system on test
To replace your battery, you’ll need a flat head screwdriver to push in the tab. Once you’ve replaced your batteries, make sure the polarity is correct, and then snap it back into place!
Don’t forget, the last thing you’ll want to do after you’ve got new batteries in is go into MyADT.com and take the system out of test mode.
That’s it!

Posted at 18:14h, 26 MayHave replace a battery (two CR2032) of door sensor, but after replacing it, sensor icon on IQpanel2 is shown like broken. I think I should reset or do something, but I don’k know how to reset or adjustment door sensor. Could you provide a manual for me ?

Posted at 01:09h, 23 JulyHello Zions! I replaced my battery in my Sensor, but now the Main Keypad is blinking that Sensor’s number and the world “Check” is under it. Is there something I need to do to reset the system? (Safewatch Pro 3000)

Posted at 15:17h, 31 JanuaryI just replace the battery and then reset the system. After the alarm comes back on the low battery notification is gone. However after about 1 hr later I am getting the low battery error again?!?!

Posted at 09:51h, 04 FebruaryIf you have replaced the battery and it does not go away check and make sure you are replacing the right battery it is saying. Zone battery or a system back up battery. If it does not go away the sensor probably needs to be replaced.

Posted at 13:13h, 31 AugustI replaced the batteries 2 aaa in the old style sensor on our front door. The chime doesn’t sound when I open the door. And the panel says ready to arm. Did I do something wrong?

Posted at 15:08h, 31 AugustNo, it sounds like the chime in that sensor might have just been turned off. Trying toggling the Chime option on your system off then back on. That should help that door chime again.
