Profile

Like most smart locks, the Assure is noticeably bigger than your standard dumb deadbolt.

Upgradeable

While we've got that battery compartment open, go ahead and take a look at that port up at the top. That's a slot for a radio module. Yale offers ones that add in Z-Wave or ZigBee compatibility for $50 each -- they'll let you sync the lock up with a platform like Wink or SmartThings. In April, they'll release a $75 module that'll let you use the lock with Apple HomeKit and, unlock it just by asking Siri.

Digital keys

Once you do, you'll arrive at the app's home screen, where your digital key chain awaits. Rotate your phone or tap the Activate Keys button, and you'll be able to unlock the Assure lock with a single tap.

Code creation

You can also create scheduled codes or digital keys that only work at certain times. The lock can accept up to 12 codes. As for digital keys, you get five free ones that you can send to friends, family and roommates. After that, they cost $1.99 a piece.

Batteries included

The lock runs on four AA batteries, which come included. The app will send you a notification if they ever start to run low.

Dead batteries?

If you ignore those notifications and the batteries die, don't worry -- you can hold a 9V battery up to these clever nodes to give the lock just enough juice for you to punch in your code and get inside.
