Wi-Fi Included: Schlage Encode, $249


The Schlage Encode lets you set up to 100 unique passcodes that are either permanent, set to expire or offer recurring access according to a schedule. A built-in alarm will sound if the lock senses an attempted break-in, and you can set the door to automatically lock when you leave.

Built-in Wi-Fi means no hub is needed to connect the Schlage Encode to other devices, although you’ll probably need to change batteries more often than locks that rely on Bluetooth. (Schlage estimates batteries will last six months.)
