- **Summary:** Yale Assure Lock 2 Plus (YRD450-N-BLE-619) is a Bluetooth smart deadbolt that lets you unlock with Apple Home Keys via iPhone or Apple Watch, plus keypad access with the Yale Access app. It supports Auto-Lock with DoorSense so the door locks automatically after it's detected closed. This lock is designed to replace a standard deadbolt and uses AA batteries.
- **Ideal For:** It's an easy replacement lock (screwdriver/around 30 minutes on standard doors) and includes an exterior keypad plus Apple Home Key tap-to-unlock and Auto-Lock with DoorSense, reducing setup and daily use complexity compared with Bluetooth-only locks that lack these built-in convenience features.
