Level Lock
By packing all the guts of a traditional smart lock into an existing deadbolt slot, the Level Lock is the smallest smart lock on the market. It has a patent-pending, six-stage, stainless steel gearbox to efficiently provide keyless access. Support for Alexa and HomeKit allows for voice, remote, or automatic control of the door, friends and family have the convenience of using their phone, voice, or even a plain old key to unlock, and the highly secure components install in just minutes. It runs up to one year on a single CR2 battery and is available in four decor-friendly finishes.
