Keypad deadbolts let authorized users unlock the door with an entry code, while key-operated deadbolts use a traditional physical key. Key-free deadbolts remove the need for a key by using a keypad or connected control system, which can support features such as unique entry codes, remote locking, and integration with security or smart-home scenes.

Check that the smart deadbolt uses a communication protocol supported by the existing system, such as Zigbee or Z-Wave, and verify whether it requires a compatible hub, controller, or specific automation platform. For Zigbee installations, confirm that the network has suitable repeating devices because these deadbolts do not function as routing nodes, and identify the lock near its final installation location.

Before installing a deadbolt, verify the door’s thickness, backset, bore-hole size, edge-bore alignment, and the strike plate’s position against the jamb. Also confirm whether the deadbolt includes a keypad, which wireless protocol or control system it uses, and that the door and existing hardware provide enough clearance for the new lock.

Deadbolts with keypads support access control through code-based entry, while some models allow multiple user codes that installers can add or remove as needed. Connected models use Zigbee or Z-Wave communication to support remote lock management and integration with compatible security, automation, or smart home systems.
