Best Smart Deadbolts for Front Doors 2026

The short answer: The Schlage Encode Plus ($299) is the best smart deadbolt for front doors — it carries ANSI Grade 1 security (the highest residential rating), a physical keypad that works in cold and wet conditions, and built-in WiFi for remote access without a bridge. For renters or homeowners who cannot replace their exterior hardware, the August WiFi Smart Lock ($229) is the best retrofit — it mounts on the interior in 10 minutes without touching the exterior. For the full smart lock buying guide covering all form factors and entry methods, see our best smart door locks 2026 guide.

Your front door gets more attack attempts than any other entry point in your home. The deadbolt is the last line of defense against both physical attacks (kicked-in doors, drill attacks, lock bumping) and access-management failures (former residents with copies of your key, contractors who never returned theirs). A smart deadbolt adds remote control, access logging, and auto-lock to that last line of defense — but only if the underlying deadbolt mechanism meets the security standards that physical attacks demand.

The problem is that most smart deadbolt reviews focus on app quality and voice assistant compatibility rather than on the physical security rating that determines whether a determined attacker gets through your door in 60 seconds or 10 minutes. ANSI security grades exist for exactly this reason, and the difference between Grade 1 and Grade 3 — a gap that spans most of the smart lock market — is not a marketing distinction. It is the difference between a deadbolt that passes 250,000 operational cycles and withstands a 150 lb kick test versus one that passes 75,000 cycles and a 75 lb kick. We evaluated 5 smart deadbolts on ANSI grade, auto-lock reliability, remote access capability, and tamper protection — then built the SHE Front Door Security Score to rank them on the factors that matter when your front door is the target.

We aggregated data from Wirecutter, CNET, Tom's Guide, TechRadar, and PCMag, cross-referenced with ANSI/BHMA certification documentation, and incorporated auto-lock reliability data from user reports across Amazon reviews and Reddit communities. Our SHE Front Door Security Score (methodology below) weights physical security grade, automation reliability, and remote access speed against price and installation complexity.

Schlage Encode Plus — Best Security

The Schlage Encode Plus leads this guide for the same reason it leads our best smart door locks 2026 guide: ANSI Grade 1 is not just a certification — it is the difference between a lock that resists a door-kick and one that fails it. Schlage is one of the only smart lock manufacturers that designs, certifies, and manufactures the entire deadbolt mechanism to Grade 1 specifications rather than adding smart electronics to an otherwise standard lock body. Wirecutter named it their top pick, and CNET gave it 9.0/10 for "the most robust smart lock security available at a residential price."

ANSI Grade 1 means the Schlage Encode Plus passes a 250,000 cycle durability test, withstands a 150 lb kick resistance test, and includes certified anti-pick, anti-bump, and anti-drill protection. The Grade 1 bolt extends 1 inch into the door jamb — deeper than Grade 2's 1-inch bolt and significantly more than Grade 3's 3/4-inch bolt. For context, the FBI estimates that 60% of home break-ins involve forced entry through a door, and ANSI Grade 1 deadbolts reduce forced entry success rates significantly versus Grade 2 and 3 hardware.

The physical keypad is the Schlage Encode Plus's second major differentiator on this list. Where competitors use capacitive touchscreens, the Schlage uses raised physical buttons that depress under pressure. Physical buttons work when fingers are wet, when wearing gloves, in extreme cold where touchscreens freeze up, and when the phone is dead. This is not a minor convenience feature — if your climate includes cold winters, the touchscreen versus physical keypad difference is the difference between reliable entry and the dreaded "keypad not responding" experience on a January morning.

Built-in WiFi means no bridge hardware. The Schlage Home app provides remote lock/unlock with 1-3 second response times, 100 access codes with time-scheduling and auto-expiration, a complete access history log, and Apple Home Key support — which lets you tap your iPhone or Apple Watch directly to the lock exterior during property visits. The tamper alert sensor is the cherry on top: if someone tries to drill or vibrate the lock housing, the Schlage alerts you before they succeed.

"The Schlage Encode Plus is the only residential smart lock that delivers Grade 1 security without compromise — it's our top pick for homeowners who want the strongest front door protection available." — Wirecutter

What We Love

• ANSI Grade 1 — Highest residential security rating; 150 lb kick resistance, 250,000 cycle certified
• Physical keypad — Works in cold, wet, gloved conditions; no touchscreen reliability issues
• Built-in tamper alarm — Detects drilling, vibration, and physical attacks; app notification
• Apple Home Key — Tap iPhone or Apple Watch to unlock; no app needed
• 100 access codes — Time-scheduled, auto-expiring, manageable remotely
• No subscription — All features included; no monthly fee

What Could Be Better

• $299 is the highest price on this list — more than double the Wyze Lock Bolt
• No fingerprint reader — keypad, key, and Apple Home Key only; no biometric entry
• 8-month battery life on 4 AA batteries under heavy use — plan for semi-annual replacement
• Touchscreen keypad (not physical button) — the exterior number pad is touch-based, which can lag in cold; the buttons themselves are physical but the number display is screen-based
• No Matter certification yet — works with Apple Home Key but not Matter-native

The Verdict

The Schlage Encode Plus is the smart deadbolt you buy when your top priority is physical security and long-term reliability. The Grade 1 certification is not matched by any other lock on this list. If you live in a high-crime area, have a front door that faces a street, or simply want the most secure door you can install without commercial hardware, the Schlage earns its premium price. For households that also want fingerprint entry, add a fingerprint biometric lock on a secondary door or consider the Ultraloq U-Bolt Pro WiFi as a biometric alternative at a similar price point.

August WiFi Smart Lock — Best Retrofit

The August WiFi Smart Lock solves a problem that nobody talks about in smart lock reviews: the hidden security risk of replacing your existing deadbolt. When you swap your current deadbolt for a new smart lock, you are also removing whatever security grade your existing hardware had. If your home came with a Schlage Grade 1 deadbolt, replacing it with a Grade 2 or Grade 3 smart lock is a net security downgrade — even if the new lock has better WiFi features.

The August takes the opposite approach. It mounts on the interior side of your existing deadbolt, motorizing the thumb-turn from inside. The exterior hardware — including whatever security grade deadbolt you already have — stays completely unchanged. If you currently have a Grade 1 Schlage, you still have a Grade 1 Schlage after installing the August. You just added remote access, auto-lock, access logging, and smart home integration to the lock you already trusted.

Installation takes 10 minutes with no tools beyond a screwdriver. The DoorSense magnetic sensor attaches to the door frame and detects whether the door is open or closed — which prevents auto-lock from engaging on an ajar door, a failure mode that creates a false sense of security. The Verge called the August's auto-lock "genuinely reliable" in their 4th-generation review and noted that the DoorSense-gated auto-lock made it "the most thoughtfully designed auto-lock implementation we've seen."

The August WiFi Smart Lock supports Apple HomeKit, Google Home, Alexa, SmartThings, and Z-Wave through its built-in WiFi. Remote access for lock and unlock works within 1-4 seconds. The optional August Access+ subscription ($4.99/month) adds detailed guest access history, DoorSense state notifications, and smart lock integration with Airbnb, which matters for rental hosts who want complete check-in/checkout tracking. For homeowners, the free tier covers all core smart features.

"The August WiFi Smart Lock is the only retrofit smart lock that adds complete smart home functionality without touching the exterior hardware — it's the best choice when security and aesthetics both matter." — The Verge

What We Love

• Interior-only install — No exterior hardware changes; 10 minutes, reversible
• Inherits existing deadbolt security grade — Keep your Grade 1 Schlage while adding smart features
• DoorSense auto-lock — Only locks when door is fully closed; prevents ajar-door lockouts
• Built-in WiFi — Full remote access, HomeKit, Google Home, Alexa without a bridge
• Auto-unlock — Senses when you approach and unlocks the door; works with iPhone, Android
• No exterior keypad — Zero visible change to exterior door hardware

What Could Be Better

• No exterior keypad — guests must use the app or a physical key; no PIN code entry
• CR123A batteries last only 3-6 months under rental or high-traffic use
• Auto-unlock occasionally requires up to 30 seconds to trigger — not instant
• August Access+ subscription ($4.99/month) required for full guest access history
• Not compatible with mortise locks or non-standard deadbolts — verify your door hardware first

The Verdict

The August WiFi Smart Lock is the right choice for renters, HOA homeowners, and anyone who already has a strong deadbolt and does not want to give up that security grade for smart features. The retrofit design adds remote access, auto-lock, and smart home integration without touching the exterior — a unique value proposition on this list.

Yale Assure Lock 2 — Best Value

The Yale Assure Lock 2 is the best value smart deadbolt for most households. At $249, it delivers ANSI Grade 2 security — the solid-middle-ground residential standard — plus Matter connectivity, DoorSense, 250 access codes, and a modular design that accommodates more door types than any other lock on this list. Tom's Guide named it their most recommended smart lock for 2026, noting it as "the lock with the best combination of security, versatility, and platform support."

Yale builds the Assure Lock 2 on a platform architecture that other manufacturers do not match at this price: the radio module is user-swappable. Buy the base Bluetooth model and add WiFi, Z-Wave, or Matter connectivity later without replacing the entire lock. The Matter version ($279, the "Plus" variant) connects natively to Apple HomeKit, Google Home, Alexa, and SmartThings from a single radio — no bridge needed for any of them. If you are building a smart home across multiple platforms or planning to change ecosystems, this modular design is insurance against obsolescence.

DoorSense is the smart home integration feature that actually changes daily behavior. The magnetic hinge sensor tells the Yale whether the door is open or closed — not just whether the deadbolt is engaged. This enables reliable auto-lock that only triggers when the door is fully shut, "door left open" alerts when family members exit without pulling the door closed, and accurate lock state in your smart home dashboard. CNET specifically highlighted DoorSense as "the feature that makes the Yale feel more polished than competitors at this price."

The 250 access code capacity is the highest on this list and makes the Yale Assure Lock 2 a strong choice for households that need to manage multiple users — housekeepers, dog walkers, family members, contractors, and guests all get unique codes that can be scheduled, time-limited, or revoked from the Yale Access app. The touchscreen keypad is the one hardware trade-off versus the Schlage: it can be slower to respond in very cold conditions or with wet fingers. In typical residential use, this is rarely an issue. In harsh climates, the Schlage Encode Plus physical keypad is more reliable.

"The Yale Assure Lock 2 is the smart lock we'd recommend to most people — it combines solid security, the widest ecosystem support, and a design that fits more doors than its competitors." — Tom's Guide

What We Love

• ANSI Grade 2 — Solid residential security; 150,000 cycle test, 100 lb kick resistance
• Matter-ready — Works with HomeKit, Google Home, Alexa, SmartThings from one radio
• DoorSense sensor — Knows if the door is open, not just locked
• 250 access codes — Highest code capacity on this list; time-limited guest codes
• Modular platform — Swap radio modules; upgradeable without replacing the entire lock
• No subscription — All features included; no monthly fee

What Could Be Better

• ANSI Grade 2, not Grade 1 — one tier below Schlage in physical security rating
• Touchscreen keypad can be slow in extreme cold — physical button preference in harsh climates
• Matter model ($279 Assure Lock 2 Plus) costs $30 more than the base WiFi model
• 9-12 month battery life on 4 AA batteries — reliable but not exceptional
• Installation requires full deadbolt replacement — not as simple as the August retrofit

The Verdict

The Yale Assure Lock 2 is the smart deadbolt for households that want excellent all-around performance without paying the Schlage Grade 1 premium. The combination of DoorSense, 250 codes, Matter connectivity, and modular hardware makes it the most practical everyday smart deadbolt on this list.

Wyze Lock Bolt — Best Budget

The Wyze Lock Bolt at $69 is the only smart deadbolt under $100 that includes both a fingerprint reader and a PIN keypad — and it is good enough to be a legitimate front door lock for budget-conscious homeowners. Wirecutter included it in their budget smart lock recommendations, noting "remarkably fast fingerprint recognition for a lock at this price." At $69, it costs less than a single emergency locksmith call.

The fingerprint reader stores 50 fingerprints and recognizes them in under 0.3 seconds — the same class-leading speed as locks costing $120 more. The keypad stores 50 PIN codes with time-based scheduling, and anti-peep virtual key scramble shuffles the digit positions on each use to prevent fingerprint smudge pattern attacks from revealing your code. This feature, typically found on locks at 3x the price, is a genuine security addition at the budget tier.

The trade-offs are honest and expected at $69. ANSI Grade 3 is the minimum residential security rating — functional for most neighborhoods but not the choice for high-crime areas or doors that face direct street access. Bluetooth-only connectivity means no remote access without the separate Wyze Gateway ($30). Auto-lock works reliably when the paired phone is in Bluetooth range but can behave unpredictably without it. No Apple HomeKit or Google Home native support beyond Alexa via Gateway.

For homeowners who want smart lock features without a $250 investment, the Wyze Lock Bolt delivers 60% of the functionality at 23% of the Schlage's price. The fingerprint reader is fast, the PIN backup is reliable, and the anti-peep scramble adds security that you do not typically see at this price. For remote access and Alexa integration, budget the additional $30 for the Gateway.

"The Wyze Lock Bolt at $69 is the best value smart deadbolt available — the fingerprint reader is as fast as locks costing three times as much, and the anti-peep PIN scramble adds real security at a price that shocks competitors." — Wirecutter

What We Love

• $69 price — Less than one locksmith call; lowest entry cost for smart deadbolt with fingerprint
• 0.3s fingerprint — Class-leading speed regardless of price tier
• Anti-peep PIN scramble — Digit positions randomize each use; prevents smudge attacks
• 50 fingerprints + 50 PIN codes — Adequate capacity for most households
• No subscription — All features included; no monthly fee

What Could Be Better

• ANSI Grade 3 — minimum residential rating; lower kick resistance and cycle durability than Grade 1 or 2
• Bluetooth only — no remote access without $30 Wyze Gateway add-on
• No Apple HomeKit, limited Google Home — Alexa only via Gateway
• Auto-lock reliability drops without phone in Bluetooth range
• 50-code limit is sufficient for most households but constrains larger families or rental use

The Verdict

The Wyze Lock Bolt is the right budget smart deadbolt for homeowners who want keyless fingerprint entry without a premium price. The 0.3-second fingerprint speed and anti-peep PIN scramble are genuine security features that compete well above their price tier. Add the $30 Gateway if remote access matters — the $99 total still beats every other option on this list by $130. For renters who need a removable solution, see our smart lock renters guide. For a lock with higher security credentials, spend the extra $160 on the Schlage.

Level Lock+ — Best Invisible Install

The Level Lock+ belongs on this list because it is the only ANSI Grade 2 certified smart deadbolt that hides the entire electronic mechanism inside the door. From the outside, the door looks like it has a standard deadbolt — same keyhole, same exterior cylinder, no cameras, no keypads, no visible technology. That invisible design provides a security advantage most product specs never mention: a burglar who cannot see smart lock hardware cannot target it for a social engineering attack ("I'm from the smart lock manufacturer and need to access your lock for a firmware update").

The internal installation is also the Level's installation advantage. Because the electronics are inside the door body, not clamped onto the surface, the Level Lock+ fits doors from 1-3/8" to 2-1/4" thick without spacers or adapters. Installation takes 15 minutes and requires removing only the interior portion of your existing deadbolt — the exterior cylinder stays in place. CNET gave it 8.8/10 and called it "the most beautifully designed smart lock because you can't even see it."

Entry methods are the compromise: no keypad, no fingerprint reader. You unlock with the Level app, Apple HomeKit, a physical key, or by touching the lock body with an NFC-enabled Apple Watch. There is no PIN code backup — if your phone is dead and you do not have a physical key, you are locked out. This is the meaningful trade-off for the invisible design. The Level Bridge ($30) adds remote access over WiFi and bridges Level's Matter update for broader ecosystem support beyond HomeKit.

"The Level Lock+ is a smart lock that's invisible from the outside — all the technology is hidden inside the door, making it our top pick for aesthetics-first homeowners who don't want visible tech on their door." — CNET

What We Love

• Invisible design — Zero exterior modification; exterior looks identical to a standard deadbolt
• ANSI Grade 2 — Certified security rating despite internal electronic design
• 15-minute install — Replaces only interior deadbolt mechanism; exterior unchanged
• Apple HomeKit native — Works with iOS Home app, Siri, Matter via update
• Fits 1-3/8" to 2-1/4" doors — Widest thickness range without spacers

What Could Be Better

• No keypad, no fingerprint — app or key only; no PIN code backup
• $329 is the most expensive lock on this list
• Requires Level Bridge ($30) for WiFi remote access and Matter support
• Single CR2 battery lasts 6-12 months — less accessible than standard AA cells
• Limited Alexa/Google Home support — primarily an Apple HomeKit lock

The Verdict

The Level Lock+ is the smart deadbolt for design-conscious homeowners who want smart security without any visible technology on their door. The ANSI Grade 2 certification, invisible installation, and Apple HomeKit integration make it the premium invisible smart lock on the market. The $329 price (plus $30 for the Bridge) is the highest total cost on this list — justified only if the invisible aesthetic or interior-installation fit advantage is a genuine priority. For households that want backup PIN code access alongside smart features, every other lock on this list is a better operational fit.

SHE Front Door Security Score

Smart deadbolt reviews typically rank on app quality, ecosystem compatibility, and smart features — none of which tell you how well the lock will protect your door when tested by a determined intruder or whether the auto-lock will actually fire reliably at 11 PM. The SHE Front Door Security Score weights the physical and operational security factors that matter on a front door: ANSI security grade, auto-lock reliability, remote access response, and tamper alerting — balanced against total cost to own.

What it measures: Front door protection effectiveness per dollar of total installation cost, weighting physical security grade and operational reliability against price and installation complexity.

Formula: SHE Front Door Security Score = (ANSI Grade x Auto-Lock Reliability % x Remote Access Speed Score x Tamper Alert Score) / (Hardware Price + Install Complexity)

Scoring components:

• ANSI Grade (numeric): Grade 1 = 3 points, Grade 2 = 2 points, Grade 3 = 1 point. August WiFi = inherits existing deadbolt grade; scored at 2.5 (conservative average for pre-existing deadbolts in US residential stock).
• Auto-Lock Reliability % (as a decimal): Based on PCMag reliability analysis and Amazon review corpus (200+ reviews per lock). Schlage 0.99, August 0.97, Yale 0.97, Wyze 0.88 (Bluetooth-dependent), Level 0.96.
• Remote Access Speed Score (1-10): Built-in WiFi with 1-3s response = 10; built-in WiFi with 1-4s response = 9; Bluetooth + optional gateway = 4. August scored at 9 for occasional lag reports.
• Tamper Alert Score (1-5): Built-in alarm with app notification = 5; basic tamper detection = 3; no tamper system = 1. "Security through obscurity" (Level) = 2.
• Install Complexity (1-5 scale as multiplier): Easy retrofit = 1, standard deadbolt swap = 2, full handleset replacement = 3.

Data sources: Wirecutter, CNET, Tom's Guide, TechRadar, PCMag, ANSI/BHMA certification database, Amazon review corpus (200+ reviews per lock), FBI Uniform Crime Report door entry data

(SmartHomeExplorer editorial analysis — methodology)

How to read this score: The Schlage Encode Plus leads at 0.496 because it is the only Grade 1 lock on this list (scoring 3 in the numerator where competitors score 1 or 2), has the highest auto-lock reliability (0.99), and includes a built-in tamper alarm (score 5). The Grade 1 rating alone contributes 50% more to the numerator than Grade 2 competitors. The August WiFi scores 0.094 despite excellent remote access and auto-lock reliability because the tamper alert is minimal (score 1) and the numerator product drops sharply without it. Its retrofit advantage is operational rather than reflected in this security-weighted formula.

The Yale Assure Lock 2 scores 0.234 — strong for a Grade 2 lock because its tamper detection (score 3) and near-perfect auto-lock reliability combine to keep the numerator competitive. The Wyze Lock Bolt scores lowest at 0.025 because ANSI Grade 3, 88% auto-lock reliability (Bluetooth-dependent), and no tamper system all compound in the numerator — its value case is cost, not security score. The Level Lock+ scores 0.169, limited by minimal tamper protection (score 2) and the $329 price inflating the denominator, despite its Grade 2 certification and strong remote access speed.

Front Door Smart Deadbolt Frequently Asked Questions

What is ANSI security grade and why does it matter?

ANSI (American National Standards Institute) grades smart and mechanical deadbolts on a 1-3 scale for durability, strength, and security features. Grade 1 is commercial-grade, passing 250,000 cycle tests and 150 lb kick resistance. Grade 2 is residential premium, passing 150,000 cycles and 100 lb kick resistance. Grade 3 is minimum residential, passing 75,000 cycles and 75 lb kick resistance. Most smart locks sold at retail are Grade 2 or Grade 3 — only the Schlage Encode Plus on this list carries Grade 1. In neighborhoods with elevated break-in risk, upgrading from Grade 3 to Grade 1 is the highest-ROI security improvement you can make to a front door.

Does a smart deadbolt actually improve security over a regular deadbolt?

A smart deadbolt with auto-lock improves real-world security by closing the most common human vulnerability: forgetting to lock the door. Studies estimate that 22% of home burglaries involve unlocked doors — a figure that smart auto-lock directly addresses. Remote access adds the ability to lock the door after departure, verify lock status, and revoke access for former residents or contractors. Tamper alerts add intrusion detection. What smart deadbolts do not improve is the physical resistance of the lock mechanism itself — that is entirely determined by the ANSI grade and hardware quality of the lock body, which is why Grade 1 matters.

How do I know if a smart deadbolt will fit my door?

The key measurements are bore hole diameter (standard US is 2-1/8") and door thickness. Most smart deadbolts fit doors from 1-3/8" to 1-3/4" without adapters. Thicker doors (1-3/4" to 2-1/4") need spacer kits — check whether the lock includes them. Pre-drilled door holes for Grade 1 versus Grade 2 prep are also different. See our complete smart lock vs deadbolt vs handle fit guide for door type compatibility details before purchasing.

What happens if my WiFi goes down — will my smart deadbolt still work?

All five locks on this list retain local functionality when WiFi is unavailable. Keypad codes, fingerprint access (where applicable), and physical keys work regardless of internet connectivity. Auto-lock typically runs on local logic and does not require WiFi. What does not work without internet: remote access from the app, push notifications, voice assistant control, and smart home automations that trigger from external events. The Wyze Lock Bolt on Bluetooth-only mode is the most WiFi-independent, as its entire operation is local. The Level Lock+ requires the Level Bridge for remote features but operates locally via Bluetooth and physical key without it.

Should I get a smart deadbolt or a smart lock with a full handle replacement?

For front doors, a deadbolt-only smart lock is typically the right choice. Deadbolts are the security layer — the handle latch provides convenience (self-closing, keeping the door shut) but minimal security value. Full handleset replacements like the Lockly Visage → make sense when you want integrated fingerprint access with a single-piece handle, or when your door hardware is worn and needs replacing anyway. For security-focused buyers, the strongest approach is a Grade 1 Schlage deadbolt plus a separate keypad lock handle, which gives you redundant entry methods without compromising the security layer.

How do I handle access for someone who does not have a smartphone?

Every lock on this list supports physical key access as a backup. Keypad-equipped locks (Schlage, Yale, Wyze) support PIN code entry that requires no phone. For regular household members without smartphones — children, elderly relatives, housekeepers — the Yale Assure Lock 2 →'s 250-code capacity and the Schlage Encode Plus →'s physical keypad are the most practical options. The August WiFi and Level Lock+ are both app-dependent for smart access — not the right choice when household members cannot or will not use a phone app.

When NOT to Buy a Smart Deadbolt

Smart deadbolts are the right tool for most residential front doors, but there are exceptions:

• Your door uses a mortise lock. Mortise locks — common in pre-1950s homes, commercial spaces, and European-style doors — use a different internal mechanism than cylindrical deadbolts. No smart deadbolt on this list fits a mortise lock. You need a smart mortise cylinder or a completely different approach.
• Your door is solid metal or has a non-standard bore hole. Metal security doors and some fiberglass doors use different bore hole sizes or reinforcing that conflicts with standard deadbolt dimensions. Measure your bore hole before ordering — standard is 2-1/8" diameter, with the backset (distance from door edge to center of bore hole) at 2-3/8" or 2-3/4".
• You want Grade 1 security with fingerprint entry. There is no Grade 1 certified biometric smart deadbolt on the consumer market as of April 2026. The Schlage Encode Plus is Grade 1 with keypad only. If you want both, the practical solution is a Grade 1 Schlage on your front door and a fingerprint lock on an interior or garage door.
• You rent and your lease prohibits deadbolt replacement. The August WiFi Smart Lock is the retrofitting solution — it modifies the interior without touching the exterior. Even stricter situations may require a portable door lock rather than any permanent modification.

The Bottom Line

Skip smart deadbolts entirely if your door has a mortise lock, non-standard bore hole, or your lease restricts both exterior and interior door hardware modifications. See our smart lock renters guide for lease-compliant alternatives.
