The Yale Assure Lock 2 is the baseline model in Yale's second-generation deadbolt line, replacing your existing deadbolt with a keypad entry system that works without handing out physical keys. It supports one-time and scheduled access codes, which is the practical draw for anyone dealing with cleaners, dog walkers or short-term guests. Yale sells it in key and key-free versions and in several finishes, and module options let it join Wi-Fi, Z-Wave or Matter setups rather than locking you into one ecosystem at purchase.
