The Philips 4000 Series WiFi Smart Deadbolt is a keyless entry lock featuring built-in Wi-Fi and Bluetooth connectivity, eliminating the need for a separate hub. Its main trade-off is the lack of emergency power options and a residential-only security grade. It is ideal for generating one-time PINs for deliveries, auto-locking for forgetful users, and remote monitoring of vacation homes.

The Yale Assure Lock is a keyless smart deadbolt featuring a Z-Wave Plus compatible touchscreen keypad for remote access and control via smart home hubs. It eliminates the need for physical keys by allowing users to program up to 25 unique PIN codes and offers one-touch locking functionality. Best suited for homeowners seeking keyless entry solutions and smart home integration via Z-Wave systems.
