Kevo Smart Lock requires 4 AA batteries (included) which should last about 1 year. The battery lifetime depends on smart lock usage and also on the installation of the Kevo Smart Lock. For instance, if there is a 'warped door condition' and the latch has excessive binding your battery lifetime could be negatively impacted. Please contact our customer service team at 1-800-327-LOCK (5625) if you have any questions or concerns about the battery life of your Kevo Smart Lock. We are happy to troubleshoot and support.
Kevo Smart Lock does not require a hardwired electrical connection.
