How to replace batteries in SimpliSafe Devices
Updated
With the exception of the Base Station, SimpliCam Indoor Camera, Smart Alarm Indoor Camera, and Key Fob, all of the components for our latest SimpliSafe have batteries that can and should be replaced periodically. When a sensor needs new batteries, your system will display an error message on the Keypad.
The Base Station requires specific rechargeable batteries; and the SimpliCam Indoor Camera only functions when connected to power, rather than being battery operated. The Smart Alarm Wireless Indoor Security Camera has non-replaceable batteries within it, and can be used on battery or plugged into a power outlet.
Quickly access the product you want to replace batteries for from the list below:
Entry Sensor
Slide the Entry Sensor off of its mounting bracket. This will expose its CR-2032 Lithium 3V battery, which can then be replaced.
Motion Sensor Gen 1
Slide the Motion Sensor off of its mounting bracket. This will expose its CR-123A Lithium 3V battery, which can then be replaced.
Motion Sensor Gen 2
The Motion Sensor Gen 2 takes a single CR-123A Lithium 3V battery and has a life expectancy of up to 4 years depending on placement and usage.
To change your Motion Sensor Gen 2 battery, slide the sensor up and off its bracket. Then, replace the battery and slide it back onto its bracket.
Glassbreak Sensor
Slide the Glassbreak Sensor off of its mounting bracket. This will expose its CR-123A Lithium 3V battery, which can then be replaced.

Lift the hatch covering the battery compartment. This will expose the Smoke Detector’s CR-123A Lithium 3V battery, which can then be replaced.
Carbon Monoxide Detector
Position the Carbon Monoxide Detector in your hand so that the “DO NOT PAINT” text is right side up, directly in front of you. The shape outlining the “CARBON MONOXIDE ALARM” text is the battery cover.
Press your finger into the oval-shaped button below the “DO NOT PAINT” text.
Once you feel the button compressing, slide the battery cover towards you. This will expose the three Energizer AA “Ultimate Lithium” 1.5V* batteries, which can then be replaced.

Using a Phillips-head screwdriver, remove the four screws that are holding the battery cover in place.
Remove the battery cover. This will expose four AA batteries, which can then be replaced.

To change your Smart Lock batteries, follow the steps below:
Slide the battery cover (the oval portion of the Lock labeled "SimpliSafe") off the device by pulling down on it.
This will expose the batteries and allow you to replace them.
Once the batteries have been replaced, put the battery cover back on and slide the compartment up until it clicks into place.

While holding the top part of the Water Sensor firmly with one hand, twist the bottom of the Water Sensor counterclockwise with your other hand. This will expose its CR-2032 Lithium 3V battery, which can then be replaced.
Wireless Outdoor Security Camera
The Wireless Outdoor Security Camera has a rechargeable battery with an expected 3-6 months lifetime, depending on usage and placement.
To remove the battery, simply untwist the cap on your Outdoor Camera. Then, use the tab on the battery to gently remove it from the battery compartment.
To charge your battery, you’ll need a USB-supported power brick that supports 5V, 7.5W+, 1.5A+ charging. Using the supplied cable, plug it into the power brick and the camera and charge your battery. To fully charge your battery, it can take up to 5 hours. You’ll know the battery is fully charged once all 3 lights are illuminated and no longer pulsing.
To replace your battery, slide it back into the battery compartment in the Outdoor Camera with the tab facing outwards. Then, twist the cap back onto the Outdoor Camera until you hear it click.
