glass breakage sensor

@jkappeler123​ To replace the battery in the Glassbreak Sensor, slide the sensor off its mounting bracket to reveal its CR-123A. This will expose the sensor's battery, which you can then replace.

I have two glass break sensors and both are frozen shut. Impossible to open. What a pain.

@landartists46​ Are your Glassbreak Sensors mounted to a wall? If they are, try sliding the sensor up while pushing it against the wall. If your sensors aren't mounted, I've found it helpful to press and hold the sensor between both hands. Then, move the hand that is holding the back of the sensor down while moving the hand that is holding the front of sensor up. This should help to reveal its batteries.

that was really helpful - the up-down method - worked first time. Thanks!

@pmeigs​ If you haven't already, I would recommend removing the Glassbreak Sensor from your account (you can do this in the SimpliSafe mobile app by navigating to My System > Device Settings > select [your Glassbreak Sensor] > Tap "X Remove Device" on the bottom of the screen) and then add the sensor back to your system using our installation guide.

@snoopyone​ To remove the Glassbreak Sensor's battery cover, you will need to slide it up and off its bracket. We also have a video showing how to do this in our Help Center, here.

@becanng​ the "CR" in the name just indicates that it's a lithium type battery. I'm pretty sure that 123A sized batteries only come as lithium type, but please make sure that yours are lithium. Those are designed for low-drain devices so they can keep operating for years at a time.

Otherwise, any trusted brand that's commonly available will do!

@scotthobats​ Unfortunately we do not offer a Glassbreak Sensor that doesn't use a battery. All of our sensors require a battery in order to function.
