Does your Keypad look like the one pictured to the left? Then you're in the right place! You've got the Gen 3 SimpliSafe system. If you purchased a system in 2017 or earlier, you have the Original SimpliSafe. Click here to view the article about the Original SimpliSafe. If you're not certain which system you have, you can tell the difference here.
With the exception of the Base Station, SimpliCam, and Keyfob, 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.
You can find a list of what batteries are required here. If you cannot find the correct type of battery for a device please contact our support center. The Base Station requires specific rechargeable batteries; and the SimpliCam only functions when connected to power, rather than being battery operated. To replace your Base Station or Key Fob’s batteries, please contact support.
