It combines a sturdy metal and zinc construction with a modern black suede finish, giving it a durable and stylish look. This deadbolt lock offers multiple ways to unlock your door, including a keypad, smartphone app, voice assistants like Alexa or Google Assistant, and even auto-unlock as you approach, making it very convenient for everyday use.

Security-wise, this lock provides reliable deadbolt protection with added smart features such as auto-locking when the door closes, so you won’t have to worry about forgetting to lock it. It connects via 2.4 GHz Wi-Fi and Bluetooth, allowing remote access and notifications through the Yale Access App. It only works within the US and Canada and does not support 5 GHz Wi-Fi, which might limit connectivity options for some users.

The lock uses a traditional keyed deadbolt with keypad and passcode entry options, balancing classic security with modern convenience. It also has a battery indicator to alert when power is low, helping avoid lockouts. The Yale lock is a secure, easy-to-install deadbolt with advanced smart home integration and multiple unlocking methods, though its Wi-Fi limitations and occasional software reliability issues should be considered.

The Yale Assure Lock 2 offers a modern, keyless entry solution for your door, making it an ideal choice for those seeking convenience and flexibility. Its standout feature is the key-free access, allowing you to unlock the door using a keypad, Auto-Unlock, or the Yale Access app on your smartphone or Apple Watch. This is particularly useful for households with multiple members or frequent visitors, as you can create adjustable codes for kids, friends, and service people.

The lock is made from satin nickel, providing a sturdy and attractive finish suitable for most home decors. It is also ANSI/BHMA Grade 2 certified, ensuring a strong level of security, and it includes features such as Bluetooth encryption and fingerprint-resistant matte keypads for added peace of mind. Installation is relatively straightforward, and the package includes everything you need, from the deadbolt to mounting plates and batteries. However, for those seeking remote access and activity tracking, the additional purchase of a Yale Wi-Fi Smart Module is necessary, which could be seen as a drawback.

The Auto-Unlock feature is handy when your hands are full, but be aware that this product only operates within the U.S and Canada. The lock's reliance on batteries (four AA included) means you'll need to keep spares on hand. For those integrating their smart home systems, it supports Apple HomeKit, iOS, and Android, but Wi-Fi capability requires an extra purchase. This lock is best suited for entry or front doors where ease of access and the ability to manage multiple access codes are priorities.

Installation is straightforward and can be done by most users with a screwdriver, fitting standard door thicknesses (1-3/8" to 1-3/4"). It runs on a single 9V battery that can last up to three years, reducing maintenance worries. The package includes everything needed for installation, such as levers for both left and right-hand doors and keys, which is a plus. Being an electronic lock, it relies on battery power—if the battery dies unexpectedly, you’ll need the physical keys to get in. While the keypad is convenient, some might find programming slightly tricky at first without careful reading of instructions. It is ideal for homeowners wanting to upgrade traditional locks to smart, keyless entry without complex installation. The lock carries a lifetime mechanical and finish warranty, plus a one-year electronics warranty, providing peace of mind. Its strong security features, ease of use, and flexible access options make it a reliable choice for most residential needs, especially for those valuing convenience and modern design.
