Smart lock shopping in 2025 presents several distinct categories of keyless entry systems. The perfect solution for your home depends on understanding these different types and your specific needs.
Deadbolt replacements
Deadbolt replacements completely substitute your existing lock hardware. You’ll need to remove your current deadbolt’s interior and exterior components. The Schlage Encode Smart WiFi Deadbolt leads this category with resilient hardware, user-friendly controls, and commercial-grade security that includes a built-in alarm system. The Yale Assure Lock 2 delivers a stylish keypad model with built-in Wi-Fi connectivity that works with multiple smart home platforms.
These full replacement locks feature a sleeker profile and more integrated features than other options. Built-in keypads, fingerprint readers, and specialized hardware like the Aqara Smart Lock U100 come standard. The U100 works with Apple’s Home Key to enable smooth iPhone and Apple Watch unlocking.
Deadbolt adapters
Deadbolt adapters let you keep your existing deadbolt and keys. These devices replace just your lock’s interior thumb turn with a motorized mechanism to trigger the existing deadbolt. The Yale Approach Lock with Wi-Fi + Keypad shows this design well – it works with almost any single-cylinder deadbolt while adding smart features.
The August Wi-Fi Smart Lock represents another popular choice that attaches to your existing deadbolt’s interior side. This modernization solution maintains your exterior lock’s appearance and lets you keep using physical keys. These adapters cost less than full replacements and serve as budget-friendly alternatives.
Lever-handle smart locks
Some doors use knobs or levers instead of deadbolts. Manufacturers now offer smart options specifically for these setups. The Schlage Encode Smart WiFi Lever works great for side entries, garage doors, and interior spaces like home offices. These locks replace your existing knob or lever completely while providing smart features similar to deadbolt versions.
Smart lever locks work best on doors without deadbolts or as extra security points inside your home. Installation requires just a single bore hole, making them perfect for interior doors that don’t have deadbolts.
Retrofit vs full replacement
Your specific situation determines whether to choose retrofit or full replacement options. Retrofit solutions offer several advantages:
- Keep your existing keys and exterior lock’s look
- Quick installation (under 10 minutes with just a screwdriver)
- Cost less than full replacements
- Perfect for renters who can’t make permanent door modifications
Full replacement locks provide different benefits:
- Sleeker, integrated design
- More feature options (built-in keypads, fingerprint readers)
- Better durability with all-new hardware
- Complete update of your door’s security
Full replacements offer the best long-term solution for homeowners who want detailed smart features. Retrofit options have improved substantially over the last several years. Models like the August Wi-Fi Smart Lock now work with keypads and other accessories that used to be available only on replacement models.
Key Features to Look for in a Smart Door Lock
Smart door locks need features that match what you’re looking for. The best ones combine security and convenience with capabilities that make them better than traditional locks.
Access methods: keypad, fingerprint, app, NFC
You can unlock smart doors in several ways without physical keys. The most popular ways to get in are:
- PIN codes: Use a unique 4-8 digit code on a touchscreen or physical keypad. Some models let you create up to 100 custom codes
- Biometric access: Your fingerprint works as a key (some locks store up to 50 fingerprints), and advanced palm vein recognition lets you enter without touching
- Smartphone control: Lock or unlock your door from anywhere using mobile apps with internet connection
- NFC/Home Key: Just tap your phone or watch on the lock (this works great with Apple Home Key on compatible models)
Most people like having backup options to get in. Security experts say smart locks should give you at least three ways to unlock the door in case one stops working.
Auto-lock and unlock options
Smart locks can secure your home without you lifting a finger. DoorSense™ technology knows when your door closes and locks it right away. You can also set the lock to secure itself after a specific time—from 30 seconds to 30 minutes.
The auto-unlock feature uses geofencing with your phone’s GPS, Bluetooth, and Wi-Fi. The lock spots you when you’re 200 meters from home and gets ready to unlock. It activates once you’re within Bluetooth range, usually 20-30 feet away. This hands-free entry helps a lot when you’re carrying groceries or have kids with you.
Battery life and backup options
These locks run on batteries that last 6 to 18 months based on how you use them and what features they have. Wi-Fi models use more battery power than Bluetooth-only versions. The apps warn you when batteries run low, and many locks show this warning on the device too.
The manufacturers have planned for dead batteries. Many locks have ports for 9V batteries as backup power. Some keep a backup keyhole just in case. To name just one example, Schlage Encode’s battery clips make changing batteries quick and easy.
Tamper alerts and activity logs
Your lock can tell you if someone tries to break in. It sends alerts straight to your phone if it detects forced entry[141]. The Aqara Smart Lock U100 goes further by shutting down its keypad after too many wrong codes.
Activity logs track everyone who comes and goes. The smartphone app shows timestamps and user details for each entry. These logs help families with kids or homes with service workers. You’ll know exactly who entered your property and when.
To conclude, pick a smart door lock by looking at which access methods work best for you. Think about whether auto-lock features fit your daily routine. Check how the battery system works and what security monitoring you need.
Smart Home Compatibility and Integration
Smart locks reach their full potential by connecting to your smart home ecosystem. The way these locks integrate with other devices has become a crucial factor for homeowners choosing keyless entry systems in 2025.
Works with Alexa, Google, and Apple Home
Voice control has become essential for anyone who owns a smart lock. Premium models now combine smoothly with all three major voice assistants. You can simply say “Hey Google, lock my door” or ask “Alexa, is my door locked?”. This hands-free feature comes in handy while you’re juggling groceries, watching kids, or welcoming guests.
Each platform brings something unique to the table. Apple Home’s users can use Home Keys on compatible locks like the Aqara U100. A quick tap of your iPhone or Apple Watch is all it takes to unlock the door. Google Assistant shines by letting you create custom routines. To name just one example, saying “Hey Google, I’m leaving” can lock your door, adjust your thermostat, and turn off lights all at once.
The Schlage Encode Plus and Yale Assure Lock 2 are great choices that work with all major platforms. The features vary between platforms though. Yale’s system won’t let you manage PINs through Apple Home – you’ll need their own app.
Matter and Thread support
Matter and Thread protocols are changing smart home integration by a lot. Matter ensures cross-platform compatibility, so your lock works with any smart home ecosystem whatever the brand. You can control your smart lock from any Matter-certified app.
Thread works alongside Matter to create a mesh network where devices talk to each other better. Thread offers several advantages over Wi-Fi:
- Batteries last longer – from months up to a year
- Everything keeps working locally even without internet
- The network heals itself if some devices go offline
Most premium smart locks now come with Matter-over-Thread technology. You’ll just need a compatible border router like Apple HomePod mini, Google Nest Hub, or Amazon Echo (4th gen) to bridge everything together.
Using smart locks with security systems
Your smart lock’s power really shows when it teams up with a security system. Connected to platforms like ADT or Alarm.com, your lock can set off a chain of events – like arming your security system at the time you lock up or turning on cameras when the door unlocks.
This setup automatically disarms the system when authorized users enter, which cuts down false alarms by a lot. The security system’s connection also lets you add door locks to complete scenes. One command can trigger multiple devices, like “Goodnight” routines that lock up every entry point at once.
The best part comes when you pair smart locks with video doorbells. Together they create a complete “smart front door” that lets you see visitors, talk to them, and let them in from anywhere. This setup is a great way to get packages delivered safely or give temporary access to service workers.
Are Smart Locks Safe? Understanding Security Standards
Security is the main concern for homeowners who want to install keyless entry systems. Smart lock safety goes beyond convenience. You need to understand industry standards, encryption practices, and clear up common misconceptions.
ANSI/BHMA lock grades explained
The American National Standards Institute (ANSI) and Builders Hardware Manufacturers Association (BHMA) set the standards for lock quality. These grades show how secure a lock is physically:
- Grade 1: Commercial-grade locks that withstand 10 ramming attacks and 250,000 cycles
- Grade 2: Residential/light commercial locks that survive 5 ramming attacks and 150,000 cycles
- Grade 3: Simple residential locks that endure 2 ramming attacks and 100,000 cycles
Traditional certification only measures physical security. BHMA is working on new standards for smart locks’ electronic components.
Encryption and data privacy
Good smart lock manufacturers use reliable encryption to protect your data. Most use AES-128 or AES-256 encryption—the same standards that governments and financial institutions trust. Many also use end-to-end encryption that keeps your data secure from your device to the lock.
Leading manufacturers take a “privacy by design” approach to protect you. Some store sensitive data like fingerprint templates on encrypted microchips instead of cloud servers. This keeps your biometric information safe even without internet connection.
Common myths about smart lock hacking
Smart locks are more secure than traditional locks, despite hacking concerns. No one has ever hacked a smart lock in real-life situations—only in controlled lab tests. Most burglars use physical force rather than complex hacking methods.
Weak passwords and outdated firmware pose the biggest security risks. So, using unique passwords and keeping your firmware updated will protect you from most vulnerabilities.
What happens during power or Wi-Fi outages
Smart locks run on battery power, not your home’s electrical system. They keep working even during blackouts. The batteries typically last 6-18 months based on how you use the lock and its connectivity features.
Quality locks come with backup options to give you peace of mind. You can use physical keys or emergency charging ports that work with 9V batteries for temporary power. Locks with internet features can still work through Bluetooth when Wi-Fi goes down.
Installation and Maintenance Tips for Homeowners
A smart lock can reshape your home security setup. You’ll need to decide whether to handle the project yourself or hire a professional.
DIY vs professional installation
Smart locks are designed with DIY installation in mind and require minimal technical skills. Homeowners can complete the installation in under 10 minutes with common household tools by following video tutorials and guides. This method saves $50 to $100 compared to hiring a locksmith.
Professional help makes sense for complex scenarios like fire-rated doors or situations that need extensive wiring. The DIY route works well for most standard doors and provides satisfaction while saving money. Your door’s alignment needs checking because slight misalignment creates excess friction and drains batteries faster.
Tools you’ll need
These essentials will help you complete a DIY installation:
- Screwdriver (both Phillips and flathead)
- Measuring tape
- Level
- Drill (sometimes necessary)
Smart locks come with installation kits that include required hardware and templates. The manufacturer’s manual should be nearby during installation since steps differ between brands.
How to manage battery life
Battery life ranges from 6 to 12 months based on usage patterns and connectivity features. Here’s how to extend battery life:
- High-quality alkaline batteries work better than rechargeable ones
- Unnecessary features like constant Bluetooth scanning should be disabled
- Lock sounds and LED status indicators can be turned off
- Wi-Fi-enabled locks should connect to a guest network to reduce traffic
Replace batteries right away when low-battery alerts show up—usually at 10-20% power. Backup batteries should be kept nearby to prevent lockouts.
Firmware updates and app settings
Software updates are just as crucial as physical maintenance. Firmware updates enhance security, fix bugs, and add new features. Many manufacturers let their companion apps update automatically.
Follow these steps to update firmware:
- Your phone needs 20% battery and your lock needs 40% battery
- Stay close enough for Bluetooth connection during the update (5-15 minutes)
- The app must stay open throughout—closing it stops the process
Check your lock’s connection status through the app regularly and adjust settings to balance convenience with power usage.
Conclusion
Smart locks have reshaped home security and brought breakthroughs right to our front doors. This piece explores how keyless entry systems provide multiple access methods, strong security standards, and uninterrupted integration with smart home systems. The shift from traditional locks to smart alternatives does more than just eliminate keys – it lets you control who enters your home and when.
Advanced encryption, backup entry methods, and physical hardening against break-ins have addressed most security concerns that stopped people from adopting smart locks. The ANSI/BHMA grading system helps you pick locks that fit your security needs. Features like tamper alerts give you peace of mind that regular locks can’t match.
Battery life isn’t a big issue with proper maintenance and emergency backup options in quality models. Users typically get 6-18 months of use before needing new batteries. The system alerts you well before power runs low.
Smart locks are worth the investment if you want both convenience and improved security. The technology keeps getting better with Matter and Thread protocols that promise smoother integration and reliability. Most homeowners can handle the DIY installation with basic tools and know-how.
These locks lead the way into home automation. They make daily life better by solving the lost key problem while adding security features that traditional locks can’t offer. Home security’s future is here, and you only need your fingerprint, smartphone, or voice to use it.
