More Details on Our Top Picks
SEPOX Keyless Entry Deadbolt with Smart Keypad and LED Indicator
This model stands out for its simplicity and affordability, making it an attractive choice for renters or homeowners seeking basic keyless entry. Unlike more advanced options like the Schlage Encode or Nuki Smart Lock, it lacks WiFi connectivity and extensive smart home integration, but it compensates with easy installation and a silent keypad mode. The limited 20 user codes and reliance on batteries mean ongoing management, and the absence of a backup power source could leave you stranded if batteries die. This pick is best suited for those who prioritize straightforward access and quick installation over advanced automation or remote control.
Pros:- Silent night mode for discreet operation
- Easy installation without door modification
- Supports up to 20 user codes
Cons:- Requires 4 AA batteries (not included)
- Limited to standard door sizes and no battery backup
Best for: Renters or homeowners needing a simple, reliable deadbolt with no fuss
Not ideal for: Smart home enthusiasts wanting full app control and integration, or those in extreme weather conditions requiring rugged durability
- IP Rating:IP54
- Battery Life:Up to 300 days with 4 AA batteries
- Supported Doors:Standard wooden and PVC doors in US and Canada
- Number of User Codes:20
Our verdict“This is a solid choice for budget-conscious users seeking straightforward keyless entry with minimal setup.”
Schlage Encode Smart WiFi Deadbolt Lock with Greenwich Trim, Matte Black
This pick makes the most sense for users who want a sleek, secure deadbolt that integrates seamlessly with their existing smart home ecosystem. Compared with the SEPOX, it offers WiFi connectivity, enabling remote management via app, and supports voice commands through Alexa and Google Home, adding convenience. However, the reliance on batteries means frequent replacements if used heavily, and WiFi dependence can sometimes introduce connectivity hiccups. Its durable design and encryption make it suitable for tech-savvy households seeking both security and automation, though it’s less ideal for those who prefer wired solutions or don’t want to manage batteries regularly.
Pros:- Easy installation with no hardwiring needed
- Remote access and control via smartphone app
- Supports voice commands with Alexa and Google Home
- High security with encrypted connection and alarm features
Cons:- Battery life may require frequent replacements with heavy use
- Requires consistent WiFi connection for full functionality
Best for: Tech-savvy homeowners wanting remote management and voice control
Not ideal for: Users who prefer wired or battery-free solutions, or those in areas with unreliable WiFi
- Finish:Matte Black
- Compatibility:WiFi, Alexa, Google Home, Ring, Airbnb
- Battery:4 AA batteries (included)
- Battery Life:Up to 6 months
- Door Thickness:1-3/8 in to 1-3/4 in
Our verdict“Ideal for users seeking a secure, remotely manageable deadbolt with smart home compatibility.”
Philips WiFi Keypad Door Lock with Handle, Built-in WiFi, APP Remote Control, Voice & Fingerprint Unlock, Keyless Entry Deadbolt
This model excels for users who want multiple access options—keypad, fingerprint, app, or voice—in a single device. Compared to the Schlage, it offers more diverse unlocking methods, including a biometric option with rapid 0.3-second fingerprint speed. Its built-in WiFi allows remote control without additional hubs, making installation straightforward for most DIY enthusiasts. However, it requires batteries (not included), and auto-lock must be enabled manually, which could be missed by some users. Designed primarily for right-opening doors, it’s best for those seeking flexibility and ease of installation, though it may be less suitable for extremely cold climates or heavy weather exposure.
Pros:- Supports multiple unlocking methods: keypad, fingerprint, app, voice
- Fast fingerprint recognition in 0.3 seconds
- No hub required for WiFi connectivity
- Easy installation suitable for most doors
Cons:- Batteries not included, need replacement

Our verdict“This lock offers a flexible, DIY-friendly option that combines biometric, keypad, and app control for versatile access.”
Nuki Smart Lock (Deadbolt) & Keypad 2 NFC – Keyless Door System with Auto-Lock, Fingerprint, and App Control
Compared with the other options, the Nuki Smart Lock supports a broad range of access methods, including smartphone, fingerprint, code, and NFC, making it one of the most flexible choices. It installs over existing deadbolts without wiring or drilling, appealing to those who want a quick upgrade without extensive modifications. Its support for Bluetooth, Wi-Fi, and Matter over Thread ensures compatibility with many smart home systems, and its IP54 rating makes it suitable for outdoor use. The main tradeoff is the need for a smartphone app for full functionality, and managing multiple access codes can become complex for large households or multi-tenant setups.
Pros:- Supports multiple access options: smartphone, fingerprint, code, NFC
- Easy retrofit installation over existing deadbolt
- Supports popular smart home systems: Alexa, Google, SmartThings
- High security with encryption and tamper alerts

This pick emphasizes advanced security features with AI-powered fingerprint verification and remote user management, making it suitable for multi-tenant properties or high-security households. It supports multiple unlocking methods—fingerprint, app, keypad, fob, and mechanical key—offering extensive flexibility. Compared with the Nuki or Philips WiFi Lock, it adds a waterproof rating of IP55 and anti-peeping password features, enhancing outdoor durability. The key tradeoff involves the need for a G1 Gateway for remote control, which adds complexity and cost. Batteries are not included, but their expected life exceeds 12 months, reducing maintenance. This lock is best for those prioritizing security, multiple access options, and outdoor resilience.
Pros:- Multiple unlocking options including fingerprint, app, keypad, and mechanical key
- AI-powered fingerprint recognition with learning capability
- Easy DIY installation without wiring or drilling

eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock with Wi-Fi, App Control, and Long Battery Life
The eufy Security Smart Lock C220 stands out for offering a variety of unlocking methods, including fingerprint, keypad, app, voice commands, and a physical key, making it a flexible choice for households with different user preferences. Compared to the Philips Wi-Fi Smart Deadbolt, the C220 excels in battery longevity, with up to 8 months on a set of batteries, reducing maintenance concerns. Its self-learning AI enhances fingerprint accuracy over time, but the BHMA Grade 3 security rating indicates it provides standard, not top-tier, physical security. Installation is straightforward, though some users might find removing the spacer cumbersome, especially on certain deadbolts. This model is ideal for users who prioritize multiple unlocking options and long battery life without needing advanced security grades or remote features.
Pros:- Multiple unlocking options including fingerprint, app, voice, and physical key

Not ideal for: Security-conscious users who require the highest grade of physical security or those needing remote access via a dedicated hub.
- Unlock Methods:Fingerprint, keypad, app, voice (Alexa/Google), physical key
- Battery Life:Up to 8 months

Philips Wi-Fi Smart Deadbolt Lock, Keyless Entry Door Lock with Code, Fingerprint, App, Voice Control, Auto Lock
The Philips Wi-Fi Smart Deadbolt makes a compelling case for users who want to control their lock remotely and enjoy real-time notifications. Unlike the eufy C220, it offers built-in Wi-Fi with a 65-foot remote range, enabling convenient access from anywhere, provided you have a stable internet connection. The auto-lock feature adds security with customizable timers, but it requires a 2.4GHz Wi-Fi network—limiting compatibility for some. Its multiple unlocking methods, including fingerprint, passcode, app, and voice, make daily access flexible. However, the absence of a door open/close sensor means you need to verify lock status manually or through other smart home integrations. This model is best for users who prioritize remote control and auto-lock functions for peace of mind.
Pros:- Multiple unlocking options including app, fingerprint, and voice control
- Supports remote access and real-time notifications
- Auto lock timer for enhanced security
- Easy DIY installation compatible with most doors
Cons:- Requires 2.4GHz Wi-Fi network, not compatible with 5GHz

- Lacks door open/close sensors for full status monitoring
Best for: Tech-savvy homeowners preferring remote access and automation features for added convenience and security.
Not ideal for: Users with unstable Wi-Fi or those who don’t want to rely on constant internet connectivity, as it requires consistent Wi-Fi for full functionality.

Factors to Consider When Choosing Smart Lock Deadbolt
Choosing the right smart lock deadbolt involves balancing features with your specific security needs and home setup. Consider how you will access the lock daily, whether remote control or biometric options are important, and how much you’re willing to spend for added convenience or security. The following factors help clarify what to look for beyond just compatibility and price.Security and Encryption
Look for smart locks that use advanced encryption protocols to prevent hacking. Features like tamper alarms, auto-locking, and secure keyless entry add layers of safety. Remember, a lock’s digital security should complement its physical strength. Investing in a model with strong encryption and security features helps protect your home from cyber threats and physical tampering.
Connectivity and Compatibility
Evaluate how the lock connects—Wi-Fi, Bluetooth, or Z-Wave—and ensure it integrates with your existing smart home ecosystem. Wi-Fi-enabled locks typically allow remote access and control without additional hubs, but may consume more power. Compatibility with voice assistants like Alexa or Google Assistant can simplify daily access, but verify these features support your devices before purchasing.
Battery Life and Power Options
Long battery life reduces the hassle of frequent replacements and ensures continuous security. Some models offer low-battery alerts or emergency power options like external USB. Consider whether the lock uses replaceable batteries or has a rechargeable power source, and choose accordingly based on your maintenance preferences.
Ease of Installation and Use
Most smart deadbolts are designed for DIY installation, but some may require additional tools or adjustments. User-friendly interfaces, clear instructions, and straightforward app setup make daily use smoother. If you’re less tech-savvy, prioritize models with simple installation and intuitive controls to avoid frustration.
Design and Aesthetics
The appearance of your lock affects curb appeal; choose finishes that match your home’s style. High-quality materials like metal or premium plastics provide durability and a more refined look. Keep in mind that more decorative designs may sometimes sacrifice security features for aesthetics—strike a balance based on your priorities.
Frequently Asked Questions
Can I replace my existing deadbolt with a smart lock?
Most smart lock deadbolts are designed to retrofit standard deadbolt holes, making replacement straightforward. However, it’s important to check the dimensions and compatibility with your current door setup. Some locks require minor adjustments or additional mounting plates, but many are DIY-friendly. Confirming compatibility before purchasing prevents installation surprises and ensures a secure fit.
How secure are smart lock deadbolts against hacking?
Smart lock deadbolts with up-to-date encryption and security protocols are generally safe from hacking attempts. Features like two-factor authentication and regular firmware updates further enhance security. However, no device is completely invulnerable, so choosing reputable brands with strong security measures is essential. Proper network security, like strong Wi-Fi passwords, also helps protect your lock from remote threats.
Do smart lock deadbolts require an internet connection to work?
Many smart locks rely on an internet connection for remote access and control, especially those with Wi-Fi capability. Some models also support Bluetooth for local control, which doesn’t need internet but limits remote features. If remote access is a priority, selecting a Wi-Fi-enabled lock is advisable, but ensure your Wi-Fi network is secure to prevent unauthorized access.
What happens if the batteries run out?
Most smart lock deadbolts include low-battery indicators well before the power runs out, allowing time to replace batteries. Some models have external power ports or backup keys to override digital access temporarily. Regularly checking battery status and keeping spares on hand helps prevent lockouts caused by power depletion.
Are biometric locks reliable for daily use?
Biometric options like fingerprint unlocking offer quick access and are generally reliable, but they can be affected by dirt, moisture, or skin conditions. Multiple users can register fingerprints, which adds convenience, but in some cases, fingerprint sensors may misread or fail to recognize certain fingers. Combining biometric access with traditional methods offers the most flexibility and security.
Conclusion
The best overall smart lock deadbolt for most users is the Schlage Encode, offering reliable security and seamless connectivity. Budget-conscious buyers should consider the eufy Security Smart Lock C220, which balances features with affordability. For those seeking advanced automation, the Nuki Smart Lock excels with its app control and auto-lock functions. Beginners or less tech-savvy homeowners will benefit from models with straightforward installation and operation, while homeowners with existing smart home setups might prioritize Wi-Fi compatibility and voice control. Your choice ultimately depends on your security needs, technical comfort, and budget.
