Why Upgrade to a Smart Door Lock?
Traditional locks do one thing: lock and unlock with a physical key. Smart door locks do all of that — and a whole lot more. From keyless entry and remote access to activity logs and auto-locking, a smart lock gives you more control over who enters your home and when. If you've ever stood at your door wondering whether you locked it, a smart lock solves that problem permanently.
But with so many options on the market, how do you choose the right one? This guide breaks down exactly what to look for.
1. Check Your Door Compatibility First
Before anything else, make sure the lock will fit your door. Most smart locks are designed for standard single-cylinder deadbolts and work with doors that are 1〸⁄₃” to 2” thick. Key things to check:
- Door thickness — measure before you buy
- Backset — the distance from the edge of the door to the center of the lock hole (usually 2〸⁄₃” or 2¾”)
- Existing deadbolt — many smart locks replace only the interior portion, keeping your existing exterior hardware
If you're renting, look for a lock that installs over your existing deadbolt without permanent modifications — these are sometimes called "retrofit" smart locks.
2. Decide on Your Entry Methods
One of the biggest advantages of smart locks is the variety of ways you can unlock your door. Consider which of these matter most to you:
- Keypad / PIN code — great for households with kids or frequent guests; no phone required
- Smartphone app — unlock remotely, check status, and grant access from anywhere
- Fingerprint / biometric — fast and hands-free; ideal for everyday use
- Key fob or card — a physical backup that doesn't require a phone or remembered PIN
- Physical key backup — always worth having, especially during power outages or connectivity issues
- Voice control — works with Alexa, Google Assistant, or Siri if you're in a smart home ecosystem
The best smart locks offer multiple entry methods so you're never locked out regardless of the situation.
3. Consider Connectivity
Smart locks connect to your home network in different ways, and this affects what features are available:
- Bluetooth only — works when you're nearby; no remote access without a hub
- Wi-Fi built-in — enables remote access and real-time notifications without extra hardware
- Z-Wave / Zigbee — requires a compatible smart home hub but offers excellent reliability and range
- Thread / Matter — the newer standard; future-proof and works across ecosystems
If remote access is important to you — checking whether you locked the door while at work, or letting in a delivery — choose a lock with built-in Wi-Fi or a hub that enables it.
4. Look at Security Ratings
A smart lock is only as good as its physical security. Look for these certifications:
- ANSI/BHMA Grade 1 — the highest residential security rating; tested for 250,000 cycles
- UL Listed — independently tested for security and durability
- Anti-pick, anti-bump, anti-drill — physical attack resistance features worth checking for
On the digital side, look for AES-128 or AES-256 encryption for app and network communication, and two-factor authentication support for your account.
5. Battery Life and Power Backup
Smart locks run on batteries — typically AA or AAA — and most last 6–12 months with normal use. Things to look for:
- Low battery alerts — push notifications before the battery dies
- Emergency power option — some locks have a 9V terminal on the exterior so you can jump-start the lock if the battery dies completely
- USB-C or rechargeable battery — increasingly common on newer models
6. Auto-Lock and Activity Logs
Two features that are easy to overlook but make a big difference in daily life:
- Auto-lock — automatically locks the door after a set time (e.g., 30 seconds after closing). A must-have for peace of mind.
- Activity log — a timestamped record of every lock and unlock event, including which user or method was used. Invaluable for households with kids, cleaners, or Airbnb guests.
