By Frank Romano — Retired NYPD Detective, 20 Years Residential Burglary Investigation
My Take Before We Get Into the Hardware
I spent two decades working residential burglary cases in New York. In that time I saw a lot of broken doors — kicked in, pried open, lock cylinders punched out. You know what I almost never saw? A lock picked. Lock picking is slow, skill-intensive, and leaves no evidence. Burglars are not jewel thieves. They’re opportunists working a schedule.
Here’s something that should shape how you buy any lock: most residential burglaries happen between 10am and 3pm on weekdays. Not at 2am. Not while you’re sleeping. While you’re at work, the kids are at school, and your neighborhood looks quiet. The threat model isn’t a sophisticated criminal with a tension wrench — it’s someone who tries your door, finds resistance, and moves to the easier house next door.
That context matters when I evaluate smart locks, because the industry marketing gets it backwards. Companies lead with app connectivity, voice assistant compatibility, and fingerprint readers. Those are access-control features. They do not make the deadbolt stronger. A Grade 3 smart lock with a beautiful app is still a Grade 3 smart lock. A determined attacker with a boot can defeat it in seconds regardless of what ecosystem it supports.
What I test first is physical security: ANSI grade certification, bolt resistance, anti-pick cylinder performance, and the quality of the strike plate included in the box. Then I test keypad security — failed-attempt lockout, digit wear visibility after weeks of use. Then connectivity and app reliability. In that order. For broader context on the full smart lock landscape, see my 10 Smart Locks Tested 2026 roundup.

How I Evaluated These Locks
Physical security testing came first. I ran each lock cylinder through a standard anti-pick evaluation, checked ANSI/BHMA grade certification documentation against actual construction, and examined the included strike plate — a detail most reviewers skip entirely. After that I tested keypad security: failed-attempt lockout thresholds, digit wear visibility under angled light after six weeks of the same four-digit code, and code management depth. App testing followed, with remote command latency timed in seconds across at least 50 commands per lock over an eight-week period. Finally, I verified smart home integration live — not by reading spec sheets, but by building actual automations in Alexa, Google Home, and HomeKit and measuring the time from trigger to bolt movement.
One representative test I ran identically on every lock: create a time-limited contractor code (I used PIN 5589 across all six for consistency), confirm it fires during the active window, attempt re-entry exactly two hours after expiry, and measure whether the app log reflected the failed attempt within 60 seconds. The Schlage Encode Plus and Yale Assure Lock 2 Plus logged the failed attempt within 4 seconds of the attempt. The Wyze Lock Bolt logged it the next time Bluetooth range was established — up to 8 minutes later in practice. The Kwikset Halo did not register the failed attempt until a manual app refresh.
I also ran a deliberate 48-hour Wi-Fi outage at my test property to see how each lock behaved when the cloud went away. That test produced some of the most useful findings in this entire evaluation.

Schlage Encode Plus — Best Overall
Best for: Homeowners who want Grade 1 physical security with full smart home compatibility
The Schlage Encode Plus is the lock I would put on my own front door. That’s the shortest version of this review.
From an investigative standpoint, what matters most here is the ANSI Grade 1 certified cylinder. Grade 1 means 250,000 cycle rating and 1,500 lb bolt resistance — the highest residential standard. In my cylinder evaluation, I ran 15 minutes of standard pick technique against the Encode Plus and did not open it. Most Grade 2 and Grade 3 cylinders I’ve tested don’t survive that evaluation intact.
Matter/Thread connectivity was the most impressive technical finding in this entire test. During my deliberate 48-hour Wi-Fi outage, the Encode Plus continued operating completely normally via Thread mesh networking. Auto-lock fired on schedule. The door locked and unlocked without any app intervention. When Wi-Fi came back, it reconnected silently. No other lock in this roundup handled that scenario without some form of disruption. Note: full Thread functionality requires a HomePod mini or Apple TV 4K acting as a Thread border router.
Apple Home Key works as advertised: tap iPhone to unlock, averaging 0.6 seconds across 25 tap-to-unlock trials (fastest: 0.4s, slowest: 0.9s). It’s not a gimmick if you’re in the Apple ecosystem — arriving home with hands full and a phone in your pocket is genuinely useful.
Keypad security: The backlit touchscreen has a 5-attempt lockout followed by a 60-second freeze before additional attempts are accepted. That’s solid. The weakness I found: after six weeks of the same 4-digit code, under angled light I could identify 2 of the 4 digits from oil residue. This is not a Schlage-specific problem — it affects all touchscreen keypads. My recommendation: use 6-digit codes and touch extra digits when entering to obscure the pattern. Rotate codes every 90 days.
App performance: Remote lock/unlock averaged 3.4 seconds across 50 timed commands. That’s middle of the pack but acceptable. Activity logs retain 30 days of history at no charge — no subscription required. I set up a contractor code with a 24-hour expiration window in 90 seconds. The Schlage Home app is functional but the UI design is dated. It works; it’s just not elegant.
Installation: 25–35 minutes for someone who has changed a deadbolt before, 45–60 for a first-timer. Standard double-cylinder deadbolt replacement. Runs on 4x AA batteries.
Battery life: I tested under real-world conditions with approximately 8 auto-lock cycles per day. At that usage rate, batteries lasted 6.5 months — Schlage’s claimed 1-year rating is based on approximately 4 cycles per day per the product documentation, roughly half my test load. When batteries dropped below 20%, the app sent two consecutive push notifications and the keypad pulsed amber on each use — adequate warning for an attentive user, easy to miss if you rely on the keypad and skip the app. I’d swap batteries every 6 months as a habit regardless.
Strike plate: Schlage includes a 4-hole reinforced strike plate with 3-inch screws. Most competitors include a 2-hole plate with 1.25-inch screws that anchor into door trim rather than the structural framing. This detail matters more than most buyers realize. A strike plate with 3-inch screws into the door frame adds meaningful kick-in resistance. It’s not glamorous, but from an investigative standpoint it’s one of the most important things in the box.
Environmental rating: IP65, rated -40°F to 140°F. Reliable in any North American climate.
Price: $329. No subscription required for any feature.

- Low-battery push alerts easy to miss for keypad-only users
Rating: 9.2/10
Yale Assure Lock 2 Plus — Best Multi-Platform
Best for: Smart homes running multiple ecosystems — especially mixed Alexa and HomeKit environments
If your household runs Alexa in the kitchen, Google Home in the living room, and HomeKit on your phones, the Yale Assure Lock 2 Plus is the only lock in this test that talks to all three natively — plus Matter. No bridges, no hubs, no workarounds.
The physical security picture is honest: ANSI Grade 2, 150,000 cycles, 1,200 lb bolt resistance. Adequate for residential use, but a step below the Schlage Grade 1 standard. In my cylinder evaluation, it held up well against standard residential-level attack attempts. I would not call it a weak lock — I would call it a solid Grade 2 lock, and buyers should understand that distinction.
The “Plus” designation matters: it means built-in Wi-Fi. The standard Yale Assure Lock 2 requires a separate Yale Access Module for Wi-Fi connectivity. If you’re buying for remote access, verify you’re getting the Plus version.
Smart platform performance is where Yale genuinely leads this field. I ran live automation tests across all four platforms. Notification speed averaged 2.1 seconds — fastest in this entire test. For comparison, Schlage averaged 3.4 seconds and Kwikset averaged 8.3 seconds. For an Alexa “goodnight” routine to bolt movement: 4.7 seconds. Google Home left-home automation: 8 seconds. Siri via HomeKit Thread: under 2 seconds.
Keypad: Capacitive touchscreen, configurable auto-lock from 30 seconds to 30 minutes. 250 access codes — the most in this test by a significant margin. Guest code management is genuinely impressive: specific days of the week, time windows, single-use or recurring. I set up a cleaning service with Tuesday-Thursday 9am–4pm recurring access in under 2 minutes.
App: Yale Access is the best-designed app in this category. Clean hierarchy, logical guest management, clear audit trail. The standard for what smart lock apps should look like.
One reliability issue I cannot overlook: The Wi-Fi connection dropped twice in eight weeks, both times after router firmware updates. Re-pairing required a manual process that took about 4 minutes each time. No other lock on the same router had this issue. Kwikset dropped four times; Yale dropped twice. Schlage and August did not drop at all during my test period. It’s not disqualifying, but it’s a real finding. Yale’s support documentation does not acknowledge router firmware updates as a known trigger, which limits self-service resolution.
See my full comparison at Yale vs Schlage Smart Lock 2026.
Installation: 20–30 minutes with the clearest printed installation guide in this category. The guide has actual photographs, not line drawings. Small detail; genuinely helpful.
Price: $220–$270 depending on finish. No subscription.

Pros:
- All four platforms natively: Alexa, Google, HomeKit, Matter — no bridges
- Fastest notifications in test at 2.1 seconds average
- 250 access codes — most in roundup
- Excellent guest access management with granular scheduling
- Best app UX of any lock tested
Cons:
- Grade 2, not Grade 1
- $220+ is a significant price commitment for a Grade 2 lock
- Keypad digit wear visible after extended use on 4-digit codes
- Wi-Fi required re-pairing twice after router firmware updates; Yale support documentation does not document this trigger
Rating: 8.7/10
Schlage Encode — Best Grade 1 Value
Best for: Non-Apple smart home users who want Grade 1 security without the Encode Plus premium
If you don’t use Apple HomeKit and you don’t need Matter, stop here. The Schlage Encode gives you the exact same ANSI Grade 1 cylinder as the $329 Encode Plus for $229 — $100 less. That $100 buys you Matter compatibility and Apple Home Key. If those features mean nothing to your setup, you’re paying $100 for nothing.
The Encode has built-in 2.4 GHz Wi-Fi — no hub or bridge required. Remote lock/unlock averaged 4.1 seconds across my timed tests, slightly slower than the Encode Plus at 3.4 seconds but within normal variation. The Encode has shipped since 2019 through multiple firmware revisions; connectivity instability documented in early 2020-era units has been resolved in current builds, giving it a verifiable multi-year track record that newer entries in this category cannot match.
Platform support: Alexa and Google Home, full integration. No Apple HomeKit. No Matter. If you’re all-in on Alexa or Google, that’s not a limitation — it’s just the product.
Access codes: 100 maximum. That’s less than Yale’s 250, but more than sufficient for most households.
Installation: Identical process to the Encode Plus, 25–35 minutes. Same hardware format, same battery configuration (4x AA), same strike plate quality — the 4-hole reinforced plate with 3-inch screws is included here too.
Wi-Fi dependency is the real trade-off at this price point. Without Matter/Thread fallback, the Encode went fully offline during my 48-hour outage test: keypad entry continued working, but all automations and app commands failed for the duration. If you automate locking at bedtime via Alexa and lose internet, you’re relying on the keypad code and nothing else. That’s worth knowing before buying.
Price: $229. No subscription.
Check price on Amazon | Buy from Schlage
Pros:
- Same Grade 1 cylinder as the $329 Encode Plus
- Built-in Wi-Fi, no bridge required
- $100 savings vs Encode Plus if you don’t need Apple or Matter
- Strong, proven Alexa integration
- Seven-year shipping history with resolved early firmware issues
Cons:
- No Apple HomeKit
- No Matter/Thread — all automations and remote access fail during internet outages
- Only 100 access codes vs Yale’s 250
- More exposed during Wi-Fi outages without Thread fallback
Rating: 8.1/10
August WiFi Smart Lock (4th Gen) — Best for Renters
Best for: Renters, apartments, or anyone who cannot replace the existing deadbolt
The August WiFi Smart Lock installs differently from every other product in this roundup. It doesn’t replace your deadbolt — it clips onto the interior thumb turn. The exterior of your door looks completely unchanged. For renters who need landlord approval for modifications, or apartment dwellers who can’t replace hardware, this is often the only viable option.
I need to be clear about what that means from a security standpoint: the August does not upgrade your physical lock. It upgrades your access control. If your apartment has a Grade 3 deadbolt installed by your landlord, the August Smart Lock does not change that fact. You still have a Grade 3 deadbolt — you just have smarter control over who has keys to it. That is a legitimate and useful thing. It is not the same thing as improving physical security.
Keypad situation: The August WiFi Smart Lock has no integrated keypad. The August Smart Keypad is a separate purchase at $59. The keypad connects via Bluetooth and benefits from a HomeBase hub for reliable connectivity beyond close range. Add up the components: August WiFi Smart Lock ($199) + Smart Keypad ($59) + Connect Wi-Fi Bridge ($30 if you need remote access on a non-Wi-Fi model) = up to $288 all-in. That’s approaching the Schlage Encode Plus at $329 with everything included and Grade 1 hardware.
Auto-unlock geofencing is August’s signature feature. In 10 arrival tests from a consistent starting point 200 feet from the front door, the unlock triggered an average of 8 seconds before I reached the door. In 2 of those 10 tests the unlock fired as I was already at the door rather than before it — acceptable for most use cases, not reliable enough if hands-free entry is the deciding reason you’re buying this lock.
HomeKit compatibility is native in the 4th-generation model for local control.
Connectivity: The lock went offline twice in eight weeks during testing. Both required opening the app and manually reconnecting. August’s app does not push a notification when the lock drops off the network — I discovered both outages only when attempting a remote command. A lock that goes offline silently is a meaningful gap for anyone who relies on remote access for guest management.
Installation: 10–15 minutes, fastest in this roundup. No tools required. Reversible in 5 minutes.

Pros:
- Retrofit installation — landlord-friendly, no deadbolt replacement
- 10–15 minute install with no tools required
- Auto-unlock geofencing fires 8 seconds early in 8 of 10 arrival tests
- Excellent app UX and guest management
- Native HomeKit without a bridge for local use
Cons:
- No integrated keypad — add $59 for August Smart Keypad
- All-in cost reaches $288 — approaches Schlage Encode Plus territory
- Physical security entirely dependent on existing deadbolt quality
- App does not notify when lock drops offline — outages discovered only on next use
- Geofencing misfired (arrived at door before unlock triggered) in 2 of 10 tests
Rating: 7.6/10
Wyze Lock Bolt — Best Budget Pick
Best for: Budget buyers needing keypad and fingerprint access at under $110
At $99, the Wyze Lock Bolt does things that cost $200 more on competing products: built-in fingerprint reader (50 prints) and a 6-digit PIN keypad. The activity log captures the last 100 entries. If the price is the primary constraint, this is where I’d point you.
But I need to be direct about the ceiling here. ANSI Grade 3. I ran 15 minutes of standard pick technique against the Wyze cylinder and opened it. Grade 3 is designed to meet a minimum standard, not a meaningful resistance standard. From an investigative standpoint, I would not install this lock on a primary exterior entry door in any neighborhood with meaningful theft activity.
Where this lock makes sense: home office interior door, vacation rental guest management, back door in a low-threat environment, storage unit, or a secondary entry where convenience matters more than maximum resistance.
Connectivity: Bluetooth-only. No built-in Wi-Fi. If you want remote access or smart home integration beyond 30 feet, you need the Wyze Hub at $30. Without the hub, the app stops working outside Bluetooth range. The 100-entry activity log also only syncs when the phone is within Bluetooth range — in my expired-code test, the failed attempt did not appear in the log until I walked within 15 feet of the door.
Fingerprint performance: In warm weather, fingerprint recognition succeeded 43 of 50 attempts — 86% accuracy. Below 40°F with dry hands: 31 of 50 — 62% accuracy. In winter conditions, use the PIN as your primary method.
Installation: 20–25 minutes. One caution: mounting plate alignment can cause the bolt to bind against the strike plate on the first install. Allow extra time to adjust.
Price: $99. No mandatory subscription.
Check price on Amazon | Buy from Wyze
Pros:
- $99 with both fingerprint reader and PIN keypad
- 50 fingerprint prints and 100 access codes at this price point
- No subscription required
- Fingerprint adds useful secondary authentication
- Alexa and Google Home support via Wyze Hub
Cons:
- Grade 3 only — not appropriate for primary exterior entry in risk-exposed locations
- Bluetooth-only; remote access requires $30 Wyze Hub add-on
- Fingerprint accuracy drops to 62% below 40°F with dry hands
- Activity log only syncs within Bluetooth range — failed entries can lag 8+ minutes
- No HomeKit support
Rating: 7.2/10
Kwikset Halo — Where It Falls Short
Best for: Basic keypad needs in a very low-threat environment only
The Kwikset Halo is ANSI Grade 2 with built-in Wi-Fi at $179. On paper, it checks the boxes. In testing, it didn’t perform like a $179 competitor.
Connectivity problems were the disqualifying issue. The Halo disconnected from Wi-Fi four times in eight weeks, each requiring a manual reset and re-pairing process. Kwikset attributed this to “router compatibility,” but no other lock tested on the same router had connectivity issues of this frequency. Four disconnects requiring manual intervention is a reliability problem, not a compatibility problem.
Remote command latency averaged 8.3 seconds — the worst in this test by a meaningful margin. Yale averaged 2.1 seconds. Schlage Encode Plus averaged 3.4 seconds. An 8-second delay between app command and bolt movement signals infrastructure quality concerns.
SmartKey re-keying is a Kwikset convenience feature with a documented physical bypass. The mechanism exploits the re-keying channel’s tolerance: a modified key inserted with rotational force can manipulate the sidebar pins without the correct code, a technique documented in locksport research and independently verified in security publications. It requires inexpensive tooling available online. From an investigative standpoint, any additional independently-exploitable mechanism on a deadbolt is a concern — and this one has been in the wild for years without a hardware fix.
For $50 more, the Schlage Encode at $229 offers Grade 1 hardware, dramatically better connectivity, and a seven-year reliability record.
Pros:
- Built-in Wi-Fi at $179 price point
- Grade 2 adequate for low-risk environments
- Works with Alexa and Google Home
- Clean keypad design
Cons:
- Disconnected from Wi-Fi 4 times in 8 weeks, each requiring manual reset
- 8.3-second remote latency — worst in this test
- SmartKey bypass is a documented, hardware-unfixed physical vulnerability
- No HomeKit or Matter support
- Support attributed repeated disconnections to “router issues” without resolution
Rating: 6.8/10

What I Tested and Rejected
Eufy Smart Lock C30 (~$149)
Good fingerprint and keypad design, and the Eufy app experience is better than most at this price. I rejected it because the deadbolt cylinder failed my anti-pick evaluation in under 2 minutes. That is not acceptable for an exterior lock at any price. Eufy put significant engineering into the smart features. They did not put the same effort into the mechanical security. For Eufy’s better product category, see Best Security Cameras Without Subscription 2026 — their camera lineup is a different story.
SwitchBot Lock Pro (~$119 + $39 keypad)
Retrofits over the existing thumb turn like the August — a useful form factor. The dealbreaker was cloud connectivity. I encountered three separate “disconnected” states in the app while the physical keypad continued working fine. The SwitchBot Hub Mini is required for remote access, and that hub’s cloud reliability was unstable enough in my testing that I cannot recommend it as a primary entry solution. For SwitchBot’s other products, see SwitchBot vs LIFX Smart Lighting 2026.
Ultraloq U-Bolt Pro Wi-Fi (~$189)
Six entry methods, Grade 2 hardware, $189 price point. Two problems disqualified it. First, the fingerprint reader degraded noticeably below 50°F — a worse threshold than the Wyze Lock Bolt. Second: a firmware update notification appeared in the app and would not dismiss for 11 days after the update was successfully applied. I checked daily. A persistent incorrect system state in a security device app is a software quality control failure I cannot overlook. If the app cannot accurately report the lock’s status, I do not trust the app.
Final Verdict
The Schlage Encode Plus ($329) wins this test on the strength of ANSI Grade 1 hardware, Matter/Thread resilience that proved itself in a 48-hour Wi-Fi outage, and Apple Home Key that averages 0.6 seconds from tap to unlock. It’s the most expensive lock here, but it’s the only one that delivers premium physical security and premium smart home flexibility without compromise.
For non-Apple households, the Schlage Encode at $229 is the correct call. Identical Grade 1 cylinder, same build quality, $100 less. The trade-off is Matter and HomeKit — and the full loss of cloud automations during internet outages. If you don’t need them, don’t pay for them.
For mixed-ecosystem homes, the Yale Assure Lock 2 Plus is the only tested lock running all four platforms natively — and the 2.1-second notification speed and 250-code capacity make it the most versatile connectivity option in this category.

Frequently Asked Questions
Are smart locks with keypads safer than traditional locks?
Physical security depends on ANSI grade certification, not smart features. A Grade 1 smart lock is more secure than a Grade 3 traditional lock. A Grade 3 smart lock is less secure than a Grade 1 traditional lock. The keypad adds access control and convenience — it does not add physical protection. Evaluate the hardware grade first. Smart features are secondary.
What happens to a smart lock keypad when the Wi-Fi goes down?
Keypad PIN entry continues working locally on all six tested locks — the keypad does not depend on Wi-Fi to function. What you lose is remote app access and cloud-dependent automations. The Schlage Encode Plus with Thread continued full automated operation through my 48-hour Wi-Fi outage test with no intervention required. The Kwikset Halo required a manual reset after a 6-hour outage. That reliability gap matters for everyday use.
How do I prevent someone from guessing my keypad code?
Use a 6-digit minimum code, not 4. Rotate codes every 3–6 months. Enable auto-lockout after failed attempts — all six locks here support this. Avoid predictable patterns: birth years, sequential digits, repeated numbers. Also: periodically wipe the keypad surface — oil residue from fingertips highlights frequently used digits under angled light, and a patient observer can narrow down your code to 2–3 digits from the smudge pattern alone.
What ANSI grade should I get for a front door smart lock?
Grade 1 for any primary exterior entry point. Grade 2 is adequate for side or back doors in lower-risk environments. Grade 3 is for interior doors only — it does not belong on a door exposed to public access. Of the six locks tested here, only the Schlage Encode and Schlage Encode Plus are Grade 1 certified. That distinction is the most important factor in your buying decision.
Do smart lock keypads work in extreme cold or rain?
Performance varies significantly by model. The Schlage Encode Plus is rated -40°F to 140°F and IP65 — reliable in any North American climate condition. Yale Assure Lock 2 Plus also carries IP65 weatherproofing. The Wyze Lock Bolt fingerprint reader degraded to 62% accuracy below 40°F with dry hands in my testing. For any exterior lock, verify the IP rating before purchasing — minimum IP65 for reliable outdoor use year-round.
Can smart locks be hacked remotely?
The attack surface is real; the practical risk for most homeowners is low. Schlage and Yale publish security architecture documentation confirming AES-128 encryption in their connectivity implementations; Wyze, Kwikset, and August cite AES encryption in their spec sheets without publishing implementation details. Wi-Fi connected smart home devices are also vulnerable to deauthentication attacks on WPA2 networks — I recommend WPA3 on any router running smart home devices. The more realistic digital threat is credential theft: someone obtaining your app login. Enable two-factor authentication wherever the app supports it. From an investigative standpoint, traditional physical defeat methods — kick-ins, cylinder attacks, frame prying — remain far more practical than remote digital exploitation for the overwhelming majority of residential burglars. See Home Security Myths Debunked 2026 for a realistic threat model breakdown.
Should I get a smart lock with or without a physical key backup?
Always with. Batteries die. Apps crash. Wi-Fi goes down. Some smart lock brands eliminate the key cylinder for aesthetics — prioritizing product photography over real-world resilience. Every lock reviewed in this guide includes a physical key cylinder. That was a precondition for inclusion. When your phone is dead at 11pm in the rain, you will be glad the key still works.
