- Note the battery type before removal.
- Use your fingers to lift the battery carefully.
- If stuck, use a non-metal tool to pry it gently.
- Dispose of the old battery properly according to local rules.
Insert The New Battery
Inserting the new battery into your ADT motion sensor is a simple but crucial task. It ensures your security system stays active and reliable. Follow these clear steps to place the battery correctly and keep your sensor working smoothly.
Check The Battery Type
Use the same type of battery as recommended in your sensor’s manual. Most ADT motion sensors use CR123A or AA batteries. Using the wrong battery can damage the device or cause it to malfunction.
Align The Battery Properly
Match the battery’s positive (+) and negative (-) ends with the markings inside the battery compartment. Incorrect alignment stops the sensor from working and may drain the battery quickly.
Place The Battery Securely
Gently insert the battery into the compartment. Push it in until it fits snugly. A loose battery might cause interruptions or false alerts in your security system.
Close The Battery Cover
After inserting the battery, close the cover firmly. Ensure it clicks or locks in place. This keeps the battery safe and protects the sensor from dust and moisture.

Close The Sensor Cover
Closing the sensor cover is a crucial step after replacing the battery in your ADT motion sensor. It ensures the device remains protected from dust, moisture, and accidental damage. A properly closed cover also guarantees the sensor functions correctly without false alarms or interruptions.
Align The Cover Properly
Before snapping the cover shut, make sure it is aligned with the sensor body. The edges should match perfectly without forcing the cover. Misalignment can cause the cover to sit loosely, compromising the sensor’s protection.
Listen For The Click
Gently press the cover until you hear a distinct click sound. This click confirms the cover is securely locked in place. If you don’t hear it, double-check the alignment and try again to avoid the cover popping open unexpectedly.
Test The Sensor After Closing
Once the cover is closed, test your motion sensor to ensure it works as expected. Walk in front of the sensor and observe if it triggers correctly. This quick test helps confirm that the battery installation and cover closure were successful.
Test The Sensor
Testing the ADT motion sensor after changing the battery ensures it works correctly. This step confirms the sensor detects motion and sends alerts properly. A well-tested sensor keeps your home safe and secure.
Power On And Reset The Sensor
First, turn on the sensor by closing its cover. This action powers the device with the new battery. Next, reset the sensor to clear old signals. Press the reset button or follow the manual’s reset instructions. This step prepares the sensor for accurate detection.
Walk Test To Check Motion Detection
Perform a walk test by moving in front of the sensor. Walk slowly across its field of view. Watch for a light or sound signal from the sensor. This reaction shows it detects motion correctly. Repeat this test a few times for consistency.
Verify Signal Transmission To Control Panel
Check if the sensor sends alerts to the main control panel. Trigger the sensor and watch the panel for notifications. A successful alert means the sensor communicates well. If no alert appears, check sensor placement and battery again.
Adjust Sensor Settings If Needed
Sometimes, sensitivity settings need tweaking after battery change. Use the control panel or app to adjust detection range. Lower or raise sensitivity based on test results. Proper settings avoid false alarms and missed detections.
Troubleshooting Tips
