Short version: the Schlage Encode is the best smart deadbolt for most buyers — built-in WiFi, no separate bridge, and the deepest review base in the category. The Kwikset SmartCode 270 is the value pick at less than half the price. And the Yale Assure Lock 2 is worth considering specifically if you’re standardizing on the Yale/August ecosystem, accepting its lower rating.

Straight Answers

Frequently Asked

What is the difference between a smart deadbolt and a smart lock?

In practice they’re used interchangeably, but "deadbolt" specifically refers to replacing or retrofitting the deadbolt mechanism itself, which is the most common form factor for a residential smart lock in the US. All three picks on this page are smart deadbolts.

Why does the Yale Assure Lock 2 have a lower rating than the other picks here?

Its average rating is genuinely lower than the Schlage Encode's or Kwikset SmartCode 270's, based on a deep base of verified ratings — a real, honestly-reported difference rather than an error. It remains a legitimate pick specifically for buyers already standardizing on the Yale or August ecosystem, where the ecosystem fit may outweigh the rating gap for that specific use case.

Does auto-lock actually work reliably?

Auto-lock (automatically locking the deadbolt after a set delay once the door closes) is a consistently praised feature across owner reviews on all three locks here, though it depends on a door sensor correctly detecting the door has closed — a door that doesn’t fully latch can prevent auto-lock from engaging, which is a door-alignment issue rather than a lock defect.
