The Yale Assure SL Connected by August costs $300 at Home Depot. It incorporates August Home technology into a Yale lock. You can set your phone to automatically unlock the door within Bluetooth range or use the integrated keypad to enter your house.

There’s a version of the lock with a keyway, too. Guests can get unique passcodes or a virtual key to enter, and access can automatically expire. A Connect Bridge (included) gives you remote access and lets the lock connect to Apple HomeKit, Alexa or Google Assistant. August DoorSense technology, also included, can set the door to automatically lock and tell you if it’s ajar.

Great Entry Level: Hornbill Smart Lock


The Hornbill smart door lock, a great entry level option, is currently priced at $115 on Amazon. That makes it a good choice for renters as well as apartment- or condo-dwellers. You will need a WiFi bridge (sold separately on Amazon) to remotely lock and unlock and monitor your entry. Operate the door with your smartphone, keypad or mechanical key.

You’ll monitor who comes and goes via your smartphone. It takes just 20 minutes with a screwdriver and a drill to install. Wrote one Amazon reviewer: “The app setup was straightforward and works great. The unit is very well made and durable.”

WiFi Included: Schlage Encode


The Schlage Encode lets you set up to 100 unique passcodes that are permanent or 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 WiFi 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.) At Lowe’s, the Schlage Encode is currently priced at $250.
