Smart Lock Assessment
A locksmith's honest take on which smart locks are actually secure and which ones aren't worth the box they come in.
Most homeowners assume that a “smart lock” means a more secure lock. After 15 years of installing, servicing, and bypassing every major brand on the market, I can tell you that the opposite is often true. The convenience features that make these locks “smart” are frequently built on hardware that is mechanically weaker than a standard deadbolt from 1985.
The Kwikset SmartKey Problem
The most common “smart” lock mechanism on the consumer market is the Kwikset SmartKey cylinder. It's found on millions of residential deadbolts and doorknobs, including many Bluetooth and Wi-Fi smart locks that use Kwikset hardware as their physical backup.
The SmartKey system replaces traditional solid pins with thin, malleable wafers and a reset carriage that allows instant rekeying without a locksmith. Convenient? Absolutely. Secure? Not even close.
A determined intruder can shatter the internal wafers by tapping a pick with a hammer, then turn the broken cylinder with a flathead screwdriver. The entire process takes under 15 seconds and leaves no visible damage on the outside of the lock.
How It Works (and Why It Fails)
A traditional pin-and-tumbler lock uses stacks of solid cylindrical pins that must reach a precise “shear line” to turn. The SmartKey system replaces these with five interlocking wafers and a sidebar. When the correct key aligns the notches in all five wafers, the sidebar retracts and the lock turns.
The problem: these wafers are not fixed in place. They're designed to be repositioned by a reset carriage so homeowners can teach the lock a new key pattern. That reset carriage and those thin wafers are the weak link. Unlike a car ignition's fixed wafers, which are engineered for durability across thousands of uses over 10 to 12 years, the SmartKey wafers sacrifice structural integrity for convenience.
Compare that to a Schlage B600 commercial deadbolt or a Medeco high-security cylinder: solid pins, hardened steel components, anti-drill plates, and patented keyways that resist picking, bumping, and forced entry. No shortcuts, no compromises.
What We Actually Recommend
Not all smart locks are created equal. Here are three approaches that pass our professional standard:
- 1.Schlage Encode Plus — Uses a real 6-pin tumbler cylinder (not wafers), carries ANSI Grade 1 certification, and supports Apple Home Key. The physical hardware is the same commercial quality Schlage puts on office buildings.
- 2.Yale Assure Lock 2 (Key-Free) — Eliminates the exterior keyway entirely. No keyhole means nothing to pick, bump, or shatter. Made by Assa Abloy, the largest commercial lock manufacturer in the world.
- 3.August Retrofit — Replaces only the interior thumb-turn while keeping your existing deadbolt completely intact. If we install a Medeco or Schlage commercial deadbolt on your door, the physical security stays untouched. The smart features are layered on top, not built into the weak point.
