Smart locks are arguably one of the most convenient smart home comforts. They can automatically detect your presence via the Bluetooth connection in your smartphone (or a Bluetooth keyfob) and unlock your doors for you with a code, a touch, or simply by approaching the lock. Select smart locks also allow you to send electronic keys to your friends and family that only grant them access during times that you specify. Some locks can even connect to a larger home automation system.
A smart lock has three components: a locking mechanism, a small motor and a wireless transceiver. The locking mechanism is usually a deadbolt lock, but can also be a doorknob. The motor, typically powered by AA batteries, turns the locking mechanism. Finally, the wireless transceiver sends and receives information from a secure mobile app or smart home system. As long as a lock has all three of these parts, it qualifies as a smart lock. The following are five of the best smart locks around right now:
