If you\u2019re looking for a premium locking system that\u2019s also the best smart lock, don\u2019t turn your nose away from the Yale Assure Lock. Its keyless design means you never have to carry keys again, relying almost solely on your mobile device or, alternatively, a password.\r\n\r\nWhy We Like It - Yale Assure Lock\r\nThe Yale Assure Lock provides a high quality premium security locking system, far better than a normal lock, while also throwing in a ton of supported devices and additional features.\r\n\r\nPerformance\r\nAll things considered, the Yale Assure SL works incredibly well. The lock will sense your phone when it\u2019s nearby, unlocking the system automatically. This also works when you leave said location. So if you forget to lock up, don\u2019t worry\u2014it\u2019ll do it for you. Compare this with the Genie Smart Lock that lets you unlock your door via your phone even when you\u2019re a million miles away on the other side of the world.\r\n\r\nAdditionally, the Yale Assure Lock\u2019s network module allows linking with smart home devices such as Apple HomeKit, Apple TV, Google Assistant, Amazon Alexa, even an Apple TV. Since it also includes the August Module, you can link up the August app, August Connect, to control the lock remotely.\r\n\r\nOnly two problems exist: using batteries, and lack of a normal keyhole. You won\u2019t need to change the 4 AA batteries often, but invest in rechargeable ones to save money. If you happen to forget your phone and the password, you\u2019re locked out because it doesn\u2019t have a normal key lock to fall back on or a fingerprint scanner like the Ultraloq UL3.\r\nDesign\r\nThe Yale Assure Lock SL Key Free belies its high quality security with its design. It\u2019s quite simple in design. Everything that it is fits into its small dimensions, which is 6 x 6 x 14 inches. With it being a touchscreen keypad, you lose any number keys. This touchscreen deadbolt also comes in a variety of finishes such as black, brass, bronze, and satin nickel, allowing it to fit into any smart home. It\u2019ll replace your lock, unlike the August Smart Lock Pro.\r\nValue\r\nThe key free Yale Assure Lock SL asks for a hefty price. Compare it with the Kwikset 909 and you\u2019re paying almost 4 times as much. With that price comes a load of compatibility and functions than other smart locks. Your phone, which is probably in your pocket than, say, a purse, is arguably more secure than a physical key. In other words, it\u2019ll be a better security system on your front door than other door locks that rely solely on pin codes every time you need to get in.\r\nYale Assure Lock Wrap Up\r\nThe Yale Assure Lock relies on your memory and phone to unlock, lacking a normal keyhole. If that isn\u2019t your cup of tea, this lock isn\u2019t for you. However, its hands-free design, smart home integration, and solid August app would argue otherwise. Sure, it runs on batteries, but that\u2019s a small price to pay for a lock that secures itself even when you forget to.
