Keyless entry systems use PINs, apps, or connected credentials instead of requiring a physical key, which can make it easier to share, change, and track access for homes, rentals, and businesses. Traditional keyed locks offer straightforward mechanical operation, while connected keyless systems may add remote lock status, notifications, auto-locking, and temporary access codes, depending on the system and its hub or app.

Check whether the existing hardware is a compatible deadbolt or single-cylinder lock, and confirm the door dimensions, bore size, and included adapter requirements, such as support for a small bore hole. For the installation location, verify whether the system is intended for indoor or exterior use, whether it mounts to a standard single-gang box or door, and whether it needs a compatible hub, app, or wired power connection.

Keyless entry systems may connect through built-in Wi-Fi or Z-Wave radios, allowing compatible smart home or security hubs and apps to manage locks, share entry codes, check status, and receive notifications. Wired access control keypads can connect to compatible access control platforms through their control output and power connection, while also supporting local management of user and temporary visitor codes.

Wi-Fi and Z-Wave keypad smart locks support shared access, user or temporary codes, activity tracking through a compatible app, and automatic locking. An indoor access control keypad also supports temporary visitor codes, while app-connected locks add remote status checks, notifications, and entry history.
