Battery-operated locks connect wirelessly through technologies such as PowerG, Z-Wave, or built-in Wi-Fi, depending on the lock and the system. Z-Wave and PowerG models typically pair with a compatible security panel or smart home hub, while Wi-Fi models can connect through the network for app-based access, notifications, and activity tracking.

Battery-operated locks generally support standard residential entry doors prepared for an existing deadbolt, including many U.S. and Canadian entryway doors. Depending on the lock, installation may accommodate doors about 1¾ to 2¼ inches thick or smaller bore holes with an included adapter, so verify the door dimensions and deadbolt preparation before installation.

Battery-operated locks may provide access through backlit keypads or touchscreens, allowing users to enter unique codes, while compatible smart-home apps can support remote locking, unlocking, notifications, and access management. Depending on the model, users may also unlock the door with a physical key, voice assistant, or app-connected mobile device.

Look for battery operated locks with an external emergency power contact that lets you use a 9V battery to power the keypad when the internal batteries run low. A physical key cylinder also provides a manual entry option on compatible models, while some key-free designs rely on the external battery connection instead.
