Security Features That Matter

A smart lock's value lies in both convenience and security. Here are the features that separate good locks from great ones:

Encryption Standards

Look for AES-128 encryption at minimum. This military-grade encryption ensures that communications between your lock and phone/hub can't be intercepted. Premium locks like the Schlage Encode Plus use even stronger AES-256 encryption.

Auto-Lock

This feature automatically locks your door after a set period (typically 30 seconds to 5 minutes). It's essential for preventing the \”Did I lock the door?\” anxiety and ensures you never forget to lock up.

Pro Tip: Look for locks that pair auto-lock with DoorSense technology, which confirms the door is actually closed before locking. This prevents locking an open door.

Guest Access & Temporary Codes

The ability to create temporary access codes for visitors, service providers, or rental guests is one of smart locks' biggest advantages. Key features to look for:

• One-time codes: Expire after single use
• Scheduled access: Only work during specific dates/times
• Recurring schedules: Work on specific days (e.g., every Tuesday for house cleaning)
• Unlimited codes: Some locks limit you to 10-20 codes; better models support 100+

Activity Logs

Comprehensive activity logs show who locked/unlocked your door and when. Essential features include:

• Timestamps for all access events
• User identification (which code/phone was used)
• Failed attempt logging
• Remote access events
• Push notifications for key events

Tamper Alerts

Smart locks with built-in alarm technology (like Schlage Encode models) can detect forced entry attempts and sound an alarm. They also send instant notifications to your phone.

Geofencing

Uses your phone's location to automatically unlock when you arrive home and lock when you leave. While convenient, consider the security implications—some users prefer manual control for maximum security.

Physical Security Ratings

Look for BHMA (Builders Hardware Manufacturers Association) certification:

• Grade 1: Highest security (recommended for exterior doors)
• Grade 2: Moderate security (acceptable for residential use)
• Grade 3: Basic security (interior doors only)

Premium locks like Schlage Encode Plus carry Grade 1 certification, meaning they've been tested to withstand 800,000 lock/unlock cycles and significant forced entry attempts.

Frequently Asked Questions

Are smart locks secure?

Yes, when properly configured. Modern smart locks use AES-128 or AES-256 encryption, the same military-grade security used by banks. They're generally more secure than traditional locks because they eliminate key vulnerabilities (lost keys, unauthorized copies). However, security depends on:

• Using strong, unique access codes
• Keeping firmware updated
• Securing your home WiFi network
• Choosing locks from reputable manufacturers

The physical lock quality matters too—look for BHMA Grade 1 certification for maximum security against physical attacks.

What happens if the battery dies?

Smart locks provide multiple low-battery warnings (typically starting at 20% battery life) through app notifications and audible beeps. If batteries die completely:

• Locks with keypads: Many include a 9V battery terminal on the exterior—touch a 9V battery to it for emergency power to enter your code
• Locks with physical keys: Use your backup key
• Retrofit locks: Your original key still works normally

Battery life typically ranges from 6-18 months depending on usage and lock type.

Can smart locks be hacked?

While theoretically possible, hacking a smart lock is extremely difficult and rare. Reputable smart locks use the same encryption that protects online banking. The biggest security risks are actually:

• Weak user codes: Avoid simple codes like 1234 or 0000
• Unsecured WiFi: Use WPA3 encryption on your home network
• Shared access: Revoke codes for people who no longer need access
• Physical attacks: Smart locks can be picked or bumped like traditional locks (choose Grade 1 certified locks)

Z-Wave and Bluetooth locks are more secure than WiFi in terms of wireless attack surface, but all modern smart locks include strong security measures.

Do smart locks work without WiFi?

It depends on the lock type:

• WiFi locks: Keypads and physical keys still work, but no remote access or notifications
• Bluetooth locks: Work completely normally (they don't need WiFi)
• Z-Wave/Zigbee locks: Local control works if your hub has backup connectivity
• Matter locks: Can work locally on your home network even without internet

Basic functions (keypad codes, manual locking) always work—it's only remote features that require internet connectivity.

Can I use a smart lock on an apartment door?

Yes, but check your lease first. Many apartments prohibit replacing locks, making retrofit models your best option:

• Best for renters: August WiFi Lock, SwitchBot Lock Pro
• Why: Install on interior only, completely reversible, no landlord approval needed
• Bonus: Landlord's key continues to work from outside

If your lease allows lock replacement, any standard smart lock will work as long as you keep the original lock to reinstall when you move out.

How long does installation take?

Installation time varies by lock type:

• Retrofit locks (August, SwitchBot): 10-15 minutes, no tools needed
• Standard replacement (Yale, Schlage, Wyze): 20-30 minutes with basic screwdrivers
• Hidden locks (Level Lock+): 45-60 minutes or professional installation
• Camera-integrated locks: 30-45 minutes, may require wiring knowledge

Most homeowners can install standard deadbolt replacement locks in under 30 minutes using just a screwdriver. The apps typically walk you through setup step-by-step.

Final Verdict: Which Smart Lock Should You Buy?

The best smart lock for you depends on your specific needs, budget, and smart home ecosystem. Here's our final guidance:

For most people: The Yale Assure Lock 2 ($249) offers the best balance of reliability, features, and ecosystem flexibility. Its modular design means you can switch platforms without replacing the lock, and it works with everything from Alexa to Apple HomeKit.
