We install smart locks on homes across the Delaware Valley and Houston every week. Most customers come to us with one of two questions: “Which smart lock should I buy?” or, after they’ve already bought one, “Why isn’t this working with my door?”
This is the buyer’s guide we wish more homeowners had read before walking into the smart-lock aisle at the big-box store. It’s organized around real decisions, not specs.
The five real decisions
Forget the marketing. When you buy a smart lock, you’re really making five decisions:
- What connectivity: Wi-Fi, Bluetooth-only, or hub-required (Z-Wave / Zigbee)?
- What entry method: Keypad, fingerprint, app-only, key-fob, or physical key backup?
- What kind of lock body: Full-replacement deadbolt, retrofit (over your existing deadbolt), or smart deadbolt + smart handle?
- What ecosystem: Apple Home, Google Home, Amazon Alexa, SmartThings, Home Assistant, brand-specific app only?
- What budget: $150 entry-level, $250 mainstream, $350+ premium?
Get those five answers right and you’re 80% of the way to the right lock.
Decision 1: Connectivity
Wi-Fi (built-in)
The lock connects directly to your home Wi-Fi. You can lock/unlock from anywhere, get alerts, share access codes — all without a hub.
Pros: Simplest setup. Works from anywhere. No bridge or hub required.
Cons: Wi-Fi locks burn batteries faster than Bluetooth. Some early Wi-Fi locks were unreliable on weak signal.
Best brands: Schlage Encode, Yale Assure with Wi-Fi, Kwikset Halo, Level Lock+.
Bluetooth + bridge / hub
The lock uses Bluetooth to talk to a separate bridge that connects to Wi-Fi. The August Connect line and the older Yale Assure line use this.
Pros: Better battery life than direct Wi-Fi locks. Bridge can sometimes be moved between locks.
Cons: Requires the bridge to be plugged in within Bluetooth range. One more component that can fail.
Best brands: August Wi-Fi (3rd-4th gen), older Yale Assure with Connect bridge.
Z-Wave / Zigbee (hub required)
The lock uses a low-power radio protocol that requires a smart-home hub (SmartThings, Hubitat, Home Assistant, Ring Alarm).
Pros: Excellent battery life. Reliable mesh network. Integrates with full smart-home setups.
Cons: Requires a separate hub. More complex initial setup. Not a fit for non-tech-savvy users.
Best brands: Yale Assure Z-Wave, Kwikset SmartCode 916, August Z-Wave.
Our recommendation for most homeowners: Wi-Fi built-in for simplicity. Z-Wave is right if you already run a smart-home hub and want the best battery life.
Decision 2: Entry method
This is where most people overcomplicate things. The honest assessment:
| Entry method | Real-world quality |
|---|---|
| Keypad (PIN code) | Best overall for most users. Works for guests, kids, dog walkers. No phone required. Code-share works with any visitor. |
| Phone app (auto-unlock) | Cool for solo users who always have their phone. Unreliable when “auto” detection misfires. Useless for guests without app. |
| Fingerprint | Improving but still imperfect outdoors in cold/wet weather. Premium feature, not essential. |
| Key fob / proximity | Convenient but easy to lose. Good as a backup, not as the only entry method. |
| Physical key backup | Should be present on every smart lock. The smart-lock-with-no-key-backup mistake has stranded a lot of people on dead batteries. |
Our recommendation: Keypad with backup physical key, ideally with phone app as well for remote management. This combination handles every real-world scenario.
Decision 3: Lock body type
Full-replacement deadbolt
You remove your existing deadbolt entirely and install the smart lock in its place. Brands: Schlage Encode, Yale Assure, Kwikset Halo, Level Lock+.
Pros: Cleanest install. Best aesthetics. Strongest mechanical security (real deadbolt body).
Cons: Replaces your existing keying — old keys no longer work. Most expensive option.
Retrofit over existing deadbolt
Mounts to the inside of your existing deadbolt and turns the existing thumb-turn. Most famous: August Wi-Fi Smart Lock.
Pros: Existing keys still work. Renters can install (no permanent modification). Easy to remove and take with you.
Cons: Bulky interior aesthetic. Battery life shorter than full-replacement. Mechanical reliability slightly lower.
Our recommendation: Full-replacement for owned homes. Retrofit (August) for renters and people who want to keep existing key functionality.
Decision 4: Ecosystem
This matters more than people expect. If you’re already in Apple Home, Google Home, or Alexa, the lock you buy should support that ecosystem natively. Otherwise the integration is awkward.
| Ecosystem | Best smart locks |
|---|---|
| Apple Home (HomeKit) | Schlage Encode, Yale Assure, August, Level Lock+ |
| Google Home | Schlage Encode, Yale Assure, Kwikset Halo, August |
| Alexa | All major brands support Alexa to some degree |
| Apple Home + Matter | Newer Schlage Encode Plus, Yale Assure 2 with Matter |
| No ecosystem (just app) | Almost any |
Our recommendation: Pick a brand that natively supports your phone’s ecosystem. The native integration is faster, more reliable, and gets better updates.
Decision 5: Budget tiers
| Tier | Price range | Examples | Trade-offs |
|---|---|---|---|
| Entry | $130–$180 | Kwikset SmartCode 914, Yale Assure Lever | Basic features, slower app, plastic interior parts |
| Mainstream | $180–$280 | Schlage Encode, Yale Assure, Kwikset Halo, August Wi-Fi | Full feature set, reliable, well-supported |
| Premium | $280–$450 | Level Lock+, Schlage Encode Plus, Yale Assure 2 with Matter | Premium aesthetics, advanced features, Matter support |
| Specialty | $400–$1,200 | Lockly Vision, biometric/dual-credential systems | Specialized features (camera built-in, fingerprint, etc.) |
Our recommendation: Mainstream tier ($180–$280) hits the sweet spot for 80% of homeowners. Don’t pay more unless you have a specific reason (Matter requirement, Level’s invisible aesthetic, fingerprint).
Brand-by-brand summary
Schlage Encode
Best for: Homeowners who want a Wi-Fi smart deadbolt with rock-solid mechanical security and broad ecosystem support. The mainstream pick.
Notes: Strong physical lock body. Reliable Wi-Fi connection. Works with Apple Home, Google Home, Alexa. Encode Plus adds Matter support and Apple home key.
Yale Assure
Best for: Homeowners who want flexibility — multiple connectivity options (Wi-Fi, Bluetooth+bridge, Z-Wave) and trim styles (deadbolt, lever, key-free).
Notes: Yale Assure 2 added Matter and refined the design. The “Assure Lock SL” key-free version is very clean visually.
August Wi-Fi Smart Lock (4th gen)
Best for: Renters and people who want to keep existing keys working. The retrofit-over-existing-deadbolt option.
Notes: Bulky on the inside. Excellent app and reliability. Auto-unlock works well for solo users.
Kwikset Halo
Best for: Budget-conscious buyers who want Wi-Fi smart-lock features. Good entry to mainstream tier.
Notes: Cheaper than Schlage Encode but slightly less premium feel. Reliable. Wide retail availability.
Level Lock / Level Lock+
Best for: Homeowners who want a smart lock that doesn’t look like a smart lock. Level fits inside the existing deadbolt body with no visible smart-lock hardware on the outside.
Notes: Premium price. Apple Home support is best-in-class. The mechanical body is very high quality. Limited entry methods (no exterior keypad on the basic Level Lock).
Ultraloq
Best for: Buyers who want fingerprint authentication at a reasonable price.
Notes: Multiple entry methods (PIN, fingerprint, key, app). Reliable in our installs. Less name-recognition but solid hardware.
Common mistakes we see
- Buying a smart lock that doesn’t fit the door. Many doors have non-standard backsets or thicker-than-standard slabs. Measure before you buy.
- Not testing the strike plate after install. A smart lock that won’t latch fully because the strike plate is misaligned will eat batteries trying to throw the bolt. We see this constantly.
- Putting a cheap smart lock on the front door and a Grade-1 lock on the back door. Burglars don’t honor your front-door priority. Match security across all exterior doors.
- Skipping the physical key backup. Smart locks die. Batteries die. Network outages happen. A physical key backup is not optional on a primary entry door.
Install — DIY or hire a locksmith?
DIY install is realistic if:
- Your existing deadbolt comes off easily
- The new lock matches your door’s backset (typically 2-3/8” or 2-3/4”)
- Your door slab thickness matches what the lock supports
- You’re comfortable with a screwdriver and basic measurements
Hire a locksmith if:
- The existing deadbolt is stuck, painted in, or older / non-standard
- Your door has alignment issues that have been “managed” by always lifting the door slightly to lock — this needs fixing before a smart lock will work
- You want it done in 60–90 minutes including testing, code setup, and app pairing
- You want someone to take responsibility if it doesn’t work

Bottom line
For most homeowners, Schlage Encode or Yale Assure 2, mainstream tier, with Wi-Fi and a keypad and a backup physical key is the right answer. Renters should default to the August retrofit option. Tech-forward households with existing smart-home hubs should look at Yale Z-Wave or Schlage Encode Plus with Matter.
