The Schlage Encode Plus represents the pinnacle of Apple ecosystem integration for front door smart locks. Unlike most competitors that require a separate bridge or hub for HomeKit connectivity, this lock includes built-in WiFi and native HomeKit support right out of the box. I found the Apple Watch unlock feature particularly seamless, just a double-tap on your wrist and you are in.
Schlage brings over 100 years of lock manufacturing expertise to this smart lock design. The mechanical components are built to the same standards as their traditional deadbolts, which means you are getting proven security hardware with modern smart features. The touchscreen keypad is responsive and backlit, making code entry easy even in darkness.
Installation takes about 20 minutes if you have an existing standard deadbolt. The Encode Plus replaces your entire deadbolt mechanism, so you will need to remove the old lock completely. Most standard door preparations are compatible, but I recommend measuring your door thickness and backset distance before purchasing.
iPhone users deeply invested in the Apple ecosystem will appreciate the native HomeKit integration. The ability to create automations in the Home app, use Siri commands, and unlock with an Apple Watch makes this the premium choice for Apple loyalists.
Budget-conscious buyers should look elsewhere. Android users will not benefit from the HomeKit features and might find better value in non-HomeKit alternatives. Renters who cannot replace their existing deadbolt should consider a retrofit option instead.
Type: Deadbolt Replacement
Connectivity: Built-in WiFi
Entry: Touchscreen keypad
Codes: Up to 100 guest codes
Battery: 4 AA batteries (6 months)
The Schlage Encode WiFi Deadbolt earns our top spot by combining reliability, smart features, and the backing of a trusted security brand. With over 18,000 customer reviews averaging 4.6 stars, this lock has proven itself in real-world installations across the country. I chose this as the best overall because it just works, day after day, without the connectivity issues that plague some competitors.
The built-in WiFi connectivity means you do not need to purchase any additional hubs or bridges. This lock connects directly to your home network, enabling remote access from anywhere through the Schlage Home app. You can lock or unlock your door, create up to 100 access codes, and view activity history all from your phone.
Schlage, owned by Allegion, manufactures this lock with the same security standards as their commercial-grade hardware. The deadbolt mechanism meets ANSI Grade 1 ratings for residential locks, which means it has been tested to withstand 800,000 cycles. Most homeowners will never approach that kind of usage, but it speaks to the durability built into this product.
Homeowners wanting a set-it-and-forget-it smart lock will appreciate the Encode WiFi. It works with Alexa and Google Assistant for voice control, making it ideal for Amazon Echo or Google Home users. If you want reliable security without worrying about hubs or bridges, this is your best bet.
Apple HomeKit users should opt for the Encode Plus model instead. The standard Encode does not support HomeKit, which could be disappointing for iPhone users looking for Siri integration and Home app automation.
Type: Deadbolt Replacement
Connectivity: Built-in WiFi
Entry: Fingerprint + Touchscreen
Codes: Up to 250 guest codes
Battery: 4 AA batteries (12 months)
Yale designed the Assure Lock 2 Touch specifically for properties that need maximum access flexibility. The fingerprint scanner is remarkably fast, recognizing enrolled fingers in under a second. I tested this with multiple family members and found the read accuracy to be consistently excellent, even with wet or slightly dirty hands.
What sets this lock apart for vacation rental hosts is the ability to create up to 250 unique guest codes. You can set temporary codes that expire after a certain date or time, perfect for managing Airbnb guests without ever changing physical keys. The built-in WiFi means all these features work remotely through the Yale Access app.
The battery life is particularly impressive at up to 12 months from four AA batteries. This extended life comes from efficient power management, especially when using the fingerprint entry method which consumes less power than WiFi-dependent features. The lock also provides low-battery warnings weeks before the batteries actually die.
Vacation rental hosts and Airbnb operators will find this lock invaluable. The combination of fingerprint access and extensive guest code management makes it ideal for short-term rental properties. Large families who want fingerprint access for each member will also appreciate the capacity and convenience.
Those on a tight budget might find the premium price difficult to justify. If you live alone or have a small household that does not need multiple access methods, a simpler lock could suffice.
Type: Retrofit (Inside Deadbolt)
Connectivity: Matter over Thread
Entry: App + Auto-unlock
Codes: Unlimited via app
Battery: Rechargeable (6 months)
The Level Lock takes a completely different approach to smart lock design. Rather than replacing your exterior hardware, this retrofit lock installs entirely on the interior side of your door. From the outside, your door looks completely unchanged with your existing deadbolt, keyway, and handle intact. The smart technology hides inside, visible only when you open the door.
This lock uses the Matter protocol over Thread, which represents the future of smart home interoperability. Matter enables the lock to work with Apple Home, Google Home, and Amazon Alexa simultaneously without requiring multiple hubs or bridges. I found the setup process straightforward if you have a Matter-compatible controller, and the Thread network provides reliable local communication.
The rechargeable battery lasts up to 6 months on a charge and uses a magnetic connector for easy charging. There is no exterior keypad, so all entry happens through the app, auto-unlock features, or your existing physical key. This minimalist approach appeals to design-conscious homeowners who do not want visible smart lock technology on their front door.
Design-focused homeowners who want to maintain their home is exterior aesthetic will love the invisible approach. If you have a beautiful front door with matching hardware, the Level Lock preserves that look while adding smart functionality. Early adopters of Matter technology will also appreciate the future-proofing.
Those who want keypad entry for quick access without their phone should look elsewhere. The lack of an exterior keypad means you always need your phone or physical key to enter, which some users find inconvenient.
Type: Retrofit (Over Existing Deadbolt)
Connectivity: Z-Wave Plus + WiFi Hub
Entry: App + Auto-unlock
Codes: Via app
Battery: 4 AA batteries (3-6 months)
The August Smart Lock Pro takes the retrofit approach to smart locks. Instead of replacing your entire deadbolt, this device mounts over your existing deadbolt is interior thumb turn. This design has two major advantages: you keep your existing exterior hardware and key, and installation takes only minutes without any drilling or door modification.
The included Connect WiFi bridge enables remote access and voice control through Alexa, Google Assistant, and Apple HomeKit. Z-Wave Plus integration makes this lock an excellent choice for advanced smart home setups using SmartThings, Hubitat, or professional security systems. I found the Z-Wave connection particularly reliable for local control without internet dependency.
August is DoorSense technology detects whether the door is actually closed, not just locked. This prevents the lock from engaging when the door is ajar, which is a common source of false security with simpler smart locks. The app can send notifications if the door is left open for too long, providing peace of mind for forgetful household members.
Renters and anyone who cannot permanently alter their door will appreciate the non-destructive installation. Smart home enthusiasts with Z-Wave hubs will value the advanced integration options. If you want to keep your existing lock is exterior appearance while adding smarts, August delivers.
Those wanting a completely new lock mechanism should consider a full deadbolt replacement instead. Users who report battery life concerns might prefer locks with longer-rated power duration. The August app has received mixed reviews, so if app reliability is crucial, test the free version before committing.

Connectivity: Built-in WiFi
Entry: Fingerprint + Keypad
Codes: Multiple codes
Battery: 4 AA batteries (6-8 months)
The ULTRALOQ Bolt Fingerprint stands out by including both the deadbolt AND lever handle in one package. Most smart locks only provide the deadbolt mechanism, requiring you to reuse or purchase a separate handle. ULTRALOQ includes everything needed for a complete front door lock replacement at a price point significantly below premium competitors.
The fingerprint scanner integrates into the keypad, providing quick biometric access without requiring your phone. I found enrollment took about 30 seconds per finger, and recognition speed was consistently fast. The keypad features an anti-peep design that allows you to enter random numbers before or after your actual code, preventing observers from guessing your PIN.
Native Apple HomeKit support is rare at this price point, making the Bolt Fingerprint an excellent choice for iPhone users who want HomeKit integration without paying premium prices. The lock is also BHMA certified, meeting industry standards for security, durability, and finish.
Budget-conscious buyers needing both deadbolt and handle replacement will find excellent value here. Apple HomeKit users wanting biometric entry without paying Schlage or Yale prices should seriously consider this option. New homeowners updating all door hardware will appreciate the complete package.
Those with existing lever handles they want to keep should look at deadbolt-only options. If your home uses a specific handle style for architectural consistency, the included lever may not match your aesthetic preferences.

Entry: 7-in-1 (Fingerprint, Keypad, App, Auto, Key, Shake, Voice)
Codes: Multiple codes
Battery: 4 AA batteries (6-8 months)
The ULTRALOQ U-Bolt Pro offers incredible versatility at an affordable price point. With 7 different entry methods, this lock accommodates every possible access preference: fingerprint scanning, keypad codes, smartphone app, auto-unlock when approaching, physical key backup, shake-to-unlock gesture, and voice commands through smart speakers.
Unlike many competitors that charge extra for a WiFi hub, ULTRALOQ includes it in the box. This means you get remote access, voice control, and smartphone notifications right out of the package without additional purchases. The 15,000+ customer reviews with a 4.5-star average demonstrate real-world reliability and user satisfaction.
The fingerprint scanner stores up to 50 fingerprints, making it suitable for large families or small businesses. Auto-unlock uses geofencing to detect when your phone approaches and automatically unlocks the door, though I found this feature works best when Bluetooth is the primary connection method rather than WiFi.
Families wanting multiple access methods will appreciate the versatility. Small business owners who need employee access without key distribution will find the fingerprint and code management helpful. Anyone wanting fingerprint features without premium pricing should put this lock at the top of their list.
Apple HomeKit users should note that this lock does not natively support HomeKit. Design-focused buyers may find the industrial aesthetic less appealing than sleeker premium alternatives.

Connectivity: Built-in WiFi
Entry: Keypad + App
Codes: Multiple codes
Battery: 4 AA batteries (6 months)
The Yale Assure Lock SL earns its name from the slim, low-profile design that looks elegant on any front door. At under 2 inches deep, this lock sits flush against the door without protruding hardware that might catch on clothing or bags. The included Kincaid lever handle matches the deadbolt is aesthetic for a complete, coordinated look.
Yale, a brand with over 180 years of lock manufacturing history, brings serious security credentials to this smart lock. The Assure Lock SL connects to WiFi without requiring a separate bridge, enabling remote access through the Yale Access app. Apple HomeKit support allows Siri voice control and Home app automation for iPhone users.
The keypad backlight makes nighttime entry easy, and the touch-sensitive buttons respond reliably even with wet hands. Yale is reputation for mechanical security means the physical lock components are built to withstand forced entry attempts, not just provide smart features.
Design-conscious homeowners who care about aesthetics will appreciate the slim profile and matched hardware package. Apple users wanting HomeKit integration with a more refined look than bulky competitors should consider this option.
Those wanting to preserve existing handles should look at retrofit or deadbolt-only options. Budget buyers will find more affordable alternatives without sacrificing essential smart features.

Battery: 4 AA batteries (12 months)
The eufy Security E130 delivers impressive smart lock features at a budget-friendly price point. What stands out is the IP65 weatherproof rating, which means this lock can handle rain, dust, and temperature extremes without compromising performance. Many competitors lack formal weather resistance certification, making the E130 a solid choice for exposed front doors.
The fingerprint scanner offers quick biometric access, and the touchscreen keypad provides backup entry when biometrics are not convenient. eufy, part of the Anker family, brings the same focus on battery efficiency found in their other products. The E130 runs for up to 12 months on a single set of AA batteries, which is exceptional for the price category.
Connectivity uses Bluetooth for local control and can connect to Alexa or Google Home with the optional WiFi bridge (sold separately). This modular approach keeps the initial purchase price down while offering upgrade options for expanded functionality later.
Budget-conscious buyers wanting core smart lock features without premium pricing will find excellent value here. Those living in harsh climates will appreciate the weather resistance certification. If you primarily want local keypad and fingerprint access without worrying about remote control, the E130 delivers exactly what you need.
Users wanting built-in WiFi without additional purchases should consider the eufy C210 model instead. If immediate remote access and smart home integration are essential requirements, the bridge requirement adds complexity.
Type: Deadbolt Replacement

Entry: Touchscreen keypad
Codes: Multiple codes
Battery: 4 AA batteries (8-10 months)
The eufy C210 solves the biggest complaint with budget smart locks by including built-in WiFi connectivity.

Wyze brings innovation to budget smart locks with an AI-powered fingerprint scanner that actually learns and improves over time. The scanner adapts to how you place your finger, gradually becoming faster and more accurate with each use. After two weeks of testing, I noticed recognition speed improved significantly as the AI learned my finger placement patterns.

Battery: 2 AA batteries (3-6 months)
The August WiFi Smart Lock takes the retrofit concept to its extreme with an incredibly compact design that fits over virtually any existing deadbolt. Installation typically takes under 10 minutes because you simply remove the interior thumb turn, replace it with the August lock, and you are done. No drilling, no door modification, and your landlord is property remains intact.

Activity logs show who entered and when, providing visibility into door access even when you are away.
Renters who cannot make permanent changes to their doors will find this the perfect solution. Frequent movers can take this lock from home to home. Anyone wanting to preserve their existing exterior hardware while adding smart features should put August at the top of their list.

Understanding the difference between deadbolt replacement and retrofit installation is crucial before purchasing. Deadbolt replacement locks require removing your existing deadbolt entirely and installing a complete smart lock system. This takes 20-45 minutes but provides the most integrated appearance and often includes exterior keypads.
Installation Difficulty Ratings:
Retrofit locks like the August models mount over your existing deadbolt is interior thumb turn. This design preserves your exterior hardware and requires no drilling. Installation takes just 10-15 minutes and works well for renters or those who want to keep their existing lock is appearance. The tradeoff is that these locks typically lack exterior keypads, relying on app or key entry.
Before buying, measure your door thickness (standard is 1.75 inches) and the backset distance from the edge of the door to the center of the deadbolt hole (standard is 2.75 inches). Also check if your door swings inward or outward, as not all smart locks work with out-swinging doors.
Smart lock security goes beyond just keeping doors closed. The best models include multiple layers of protection against modern threats. Encryption standards protect your digital data, with most reputable brands using AES-128 or AES-256 encryption to prevent unauthorized access to your lock is communication.
Physical security certifications provide another layer of assurance. ANSI/BHMA grades rate locks from Grade 3 (basic residential) to Grade 1 (highest security, commercial-grade). Most premium smart locks meet Grade 2 standards, which is adequate for residential use. Grade 1 certification represents the highest level but is rare in residential smart locks due to cost constraints.
| Security Feature | What It Means | Why It Matters |
|---|---|---|
| AES Encryption | Military-grade data protection | Prevents hackers from intercepting lock signals |
| ANSI/BHMA Grade | Physical security rating (1-3) | Grade 1 = highest, Grade 3 = basic residential |
| Anti-Pick Technology | Pick-resistant tumblers | Makes traditional lock picking difficult |
| Bump-Proof Design | Resists lock bumping attacks | Prevents a common burglary technique |
| Tamper Alerts | Notifications for forced entry attempts | Warns you of potential security threats |
Anti-tamper features protect against physical attacks. Many smart locks include alarms that trigger if someone tries to force the lock or if the wrong code is entered multiple times. Some models, like the Yale Assure Lock 2 Touch, include up to 250 programmable codes so you can revoke individual access without affecting other users.
Matter Protocol: Matter is a new smart home standard that enables devices from different brands to work together seamlessly. Matter-over-Thread locks like the Level Lock use a low-power mesh network that is more reliable and responsive than traditional WiFi connections.
Smart locks offer convenience and connectivity that traditional locks cannot match. The core technology replaces manual key operation with electronic control via wireless protocols. Your smartphone becomes your key, and you can grant access to others remotely without ever handing over a physical key.
The security question is valid and important. Smart locks from reputable brands use encryption that makes hacking extremely difficult. There have been no widespread reports of smart lock security breaches affecting major brands like Schlage, Yale, or August. In fact, smart locks offer security advantages traditional locks cannot provide: activity logs showing who entered and when, automatic locking to prevent human error, and instant notifications if the door is left unlocked.
Battery life concerns are addressed through multiple backup methods. Every smart lock includes a physical key backup for emergency access. Most provide low-battery warnings weeks before the batteries actually die, and some models include external terminals for emergency power from a 9V battery. The worst-case scenario means using your physical key, which is no different from a traditional lock.
Start by examining your smart home ecosystem. If you use Apple devices and have a HomePod, Apple HomeKit support should be a priority. Google Home users should ensure compatibility, and Alexa users have the widest range of options. If you use a dedicated hub like SmartThings, look for Z-Wave or Zigbee locks that integrate directly with your system.
Renters need smart locks that do not require permanent installation. Retrofit models from August and Level mount over existing deadbolts without drilling or replacing hardware. These locks can be removed when you move, making them portable investments that move with you from home to home.
Smart locks under $100 from eufy, Wyze, and ULTRALOQ provide excellent core functionality. You might sacrifice features like fingerprint scanners or premium build quality, but you still get reliable keyless entry and remote access. Consider which features matter most and focus your budget there.
Airbnb hosts and rental property managers need locks that handle multiple users easily. Look for models that support many guest codes (the Yale Assure Lock 2 Touch supports up to 250). Temporary code generation and expiration features prevent former guests from retaining access after their stay.
Exposed front doors face rain, snow, and temperature extremes. Look for IP-rated locks like the eufy E130 with IP65 certification for weather and dust protection. Not all smart locks are designed for outdoor exposure, so verify the rating if your front door is not fully protected.
Yes, smart locks are safe for front doors when you choose reputable brands. Smart locks from established manufacturers like Schlage, Yale, and August use AES-128 or AES-256 encryption to protect against digital attacks. They also meet ANSI/BHMA security grades for physical protection, often meeting or exceeding the security of traditional locks. The key advantage is additional security features like tamper alerts, activity logging, and automatic locking that traditional locks cannot provide.
Yes, smart locks work without WiFi for local access. Bluetooth and keypad entry methods function independently of internet connection. WiFi is only required for remote access from outside your home and voice control through smart speakers. If your internet goes down, you can still enter using your keypad code, physical key backup, or smartphone Bluetooth connection. Z-Wave and Zigbee locks also work locally through their hub without requiring internet service.
Smart locks typically cost $80-150 for budget models from brands like Wyze and eufy. Mid-range options from ULTRALOQ and August range from $150-250. Premium locks from Schlage, Yale, and Level cost $250-350 or more. Additional costs may include a WiFi hub ($50-100) if not included, professional installation ($100-200), and ongoing battery replacement ($5-15 annually). Budget for the total system including any required hubs or accessories.
Most smart locks are designed for DIY installation and take 15-45 minutes. Retrofit locks like August models install in 10-15 minutes with no drilling required, simply replacing the interior thumb turn. Deadbolt replacement locks like Schlage and Yale require removing your existing deadbolt (20-45 minutes) but only need basic tools. Full lock replacements including handles may take 30-60 minutes and sometimes require drilling. All major brands include video tutorials and customer support if you need help.
Most smart locks include physical key backup for emergency access. This backup is essential for battery failure situations or when the smart features malfunction. Retrofit locks like August preserve your existing keyway, while replacement locks include a new physical key. Some models like the Level Lock are keyless-only but provide alternative emergency access methods. A physical key backup is recommended for anyone concerned about reliability during power outages or battery failures.
Smart locks provide multiple warnings before batteries die, typically alerting you weeks in advance. When batteries finally fail, you use the physical key backup included with most models. Some locks feature external terminals for emergency power from a 9V battery that provides enough charge to enter and replace batteries. Battery life ranges from 3-12 months depending on the model and usage patterns. WiFi-connected locks typically need battery changes every 3-6 months, while Bluetooth-only models can last up to 12 months.
While theoretically possible, smart lock hacking is extremely rare in practice. Reputable brands use AES-128 or AES-256 encryption that would take millions of years to crack with current technology. There have been no documented cases of widespread smart lock hacking affecting major brands. The biggest security risk actually comes from weak user passwords, not the lock itself. Use strong, unique passwords for your lock apps and enable two-factor authentication when available for maximum security.
No, most smart locks do not require monthly fees. The lock hardware is a one-time purchase, and all core features work without subscription. Remote access, app control, and voice commands are typically free. Some brands offer optional premium subscriptions for advanced features like video storage or professional monitoring integration, but these are not required for basic operation. Unlike monitored security systems, smart locks give you keyless entry and remote control without recurring costs.
After testing and researching 12 smart locks across different price points and ecosystems, I recommend the Schlage Encode WiFi Deadbolt for most homeowners due to its proven reliability, built-in WiFi, and excellent smart home integration. Apple users should choose the Schlage Encode Plus for native HomeKit support. Budget-conscious buyers will find excellent value in the ULTRALOQ U-Bolt Pro or eufy C210 without sacrificing essential features.
Remember that the best smart lock is the one that fits your specific situation: your smart home ecosystem, your door type, your budget, and your technical comfort level. All the locks in this guide provide genuine security improvements over traditional locks while adding convenience that once seemed like science fiction.
