A clean look with no keyed cylinder — entry is handled by PIN code (and supported app control depending on model). These are ideal when you want no physical key management and a simple, modern install.
Best for: rentals, shared access, staff codes, and clean modern doors
Choose key-free if: the customer is comfortable using codes/apps as the primary access method
Confirm before ordering: door prep/fit and the connectivity type (Wi-Fi / Bluetooth / Z-Wave)
