Level Touch Review: Ushering in a New Generation of Smart Locks On 4/11/21 at 10:00 AM EDT The smart lock category, and being able to remotely secure your house, is an integral part of the smart home ecosystem. The problem is that up until now, smart locks have been easy to spot from a mile away. They have typically added a bulbous device to a door, possibly killing a home decor's aesthetic. The Level Touch smart lock, on the other hand, is invisible in this regard and will fit in with many more homes. You can still use a key with the lock if the battery dies or if you don't want to use the app.
