One of the biggest hurdles to smart lock adoption has been the need to replace an existing lock, or otherwise cover it with an ungainly box. The Level Lock requires neither of those compromises. It's designed to fit seamlessly into an existing deadbolt slot, preserving the look of the entryway while a patent-pending, six-stage, stainless steel gearbox efficiently provides keyless access. Bluetooth provides local access and lets the owner share access with friends and family via an app, while HomeKit integration allows for remote door operation and voice control via Siri. Highly secure, the lock installs in just minutes and runs for up to one year on a CR battery.
