How to Replace the Original SimpliSafe® System's Batteries
Updated
| Does your Keypad look like the one pictured to the left? Then you're in the right place! You've got the Original SimpliSafe system. If you purchased a new system in 2018 or later, you likely have the Gen 3 SimpliSafe. In that case, visit the How to Replace Batteries in SimpliSafe® Devices article. If you're not certain which system you have, you can see the difference on our Help Center. |

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.
