Detailed Reviews

1. Schlage Encode Plus — Best Overall Smart Lock

Price: ~$300 | ANSI Grade 1 | Rating: 9.5/10

The Schlage Encode Plus is the most secure smart lock you can buy for residential use. It’s the only ANSI Grade 1 smart lock — the highest security rating — meaning it withstands 800,000 cycles and 10 strikes. It was also the first lock to support Apple Home Key, letting you unlock with a tap of your iPhone or Apple Watch.

Key Features:

• Apple Home Key — unlock with iPhone/Apple Watch (even with dead phone battery via power reserve)
• Built-in Wi-Fi — no hub or bridge required
• Up to 100 unique access codes with scheduling
• Auto-lock and built-in alarm sensor
• Works with Alexa, Google Assistant, HomeKit
• Snap-n-Stay design for easy solo installation

Pros: ANSI Grade 1 (best security), Apple Home Key, no hub needed, excellent build quality
Cons: $300 price tag, limited finishes (matte black, satin nickel), no fingerprint reader
Battery Life: ~1 year (4x AA batteries)

Best paired with: An Apple HomeKit security system like Abode for full smart home automation — auto-lock when you arm the system, unlock when you disarm.

2. Yale Assure Lock 2 — Best for Smart Home Flexibility

Price: ~$200-280 | ANSI Grade 2 | Rating: 9.2/10

Yale’s modular approach is genius — buy the base lock, then choose your connectivity module (Wi-Fi, Bluetooth, Matter, or Z-Wave). This future-proofs your investment because you can swap modules as technology evolves.

Key Features:

• Modular design — swap between Wi-Fi, Matter, Z-Wave, or Bluetooth modules
• Touchscreen or keypad options
• Up to 250 access codes
• DoorSense auto-lock with open-door detection
• Works with Alexa, Google, HomeKit (module dependent)

Pros: Most versatile connectivity, future-proof modular design, slim profile, Matter support
Cons: Modules sold separately ($30-80), Grade 2 only, touchscreen can be slow in cold weather
Battery Life: ~9-12 months (4x AA batteries)

Tip: Get the Z-Wave module if you’re pairing with a security system like Abode — Z-Wave is more reliable than Wi-Fi for lock control and uses less battery.

3. August Wi-Fi Smart Lock (4th Gen) — Best Retrofit Lock

Price: ~$230 | ANSI Grade 2 | Rating: 8.8/10

August’s genius is that it installs over your existing deadbolt — you keep your physical key as a backup. It’s the easiest smart lock to install (under 10 minutes) and the best choice for renters who can’t change their locks.

Key Features:

• Retrofit design — keeps existing key and exterior hardware
• Built-in Wi-Fi — no bridge needed
• Auto-lock and auto-unlock (geofencing)
• DoorSense open/close detection
• Apple HomeKit, Alexa, Google Assistant

Pros: Keeps your existing key, renter-friendly, great geofencing, easy 10-minute install

Battery Life: ~3-6 months (2x CR123A batteries)

4. Abode Lock — Best for Security System Integration

Price: $99 | ANSI Grade 2 | Rating: 8.5/10

• Auto-lock when system is armed (CUE automation)
• Auto-unlock when you disarm via keypad or app
• Lock status in Abode app alongside sensors and cameras

Battery Life: ~1 year (4x AA batteries)

Best automation combo: Door opens → camera starts recording. System armed → door auto-locks. You arrive home (geofence) → system disarms + door unlocks.

Smart Lock Buying Guide: What Actually Matters

Security Rating (ANSI Grade)

The ANSI/BHMA grading system rates lock durability and security:

Every lock on our list is Grade 1 or 2. Don’t buy a Grade 3 smart lock for an exterior door.

Connectivity: Wi-Fi vs Z-Wave vs Bluetooth vs Matter

Our recommendation: If you have a security hub like Abode, use Z-Wave — it’s more reliable and uses far less battery than Wi-Fi. If you’re standalone, Wi-Fi is the most convenient.

Security System Integration

A smart lock becomes far more powerful when connected to a security system:

• Auto-lock when armed: Forget to lock the door? The system does it for you when you arm it
• Unlock on disarm: Disarm from your phone and the door unlocks — hands full with groceries? No problem
• Lock status in one app: See if your door is locked right next to your camera feeds and sensor status
• Guest access + monitoring: Give a code to the dog walker and get an alert when they arrive

FAQ

Are smart locks safe?

Yes — most smart locks are as secure or more secure than traditional locks. Look for ANSI Grade 1 or 2 ratings. The Schlage Encode Plus (Grade 1) is actually harder to defeat than most standard deadbolts. Smart locks add security features traditional locks can’t match: auto-locking, access logs, and remote lock confirmation.

Can smart locks be hacked?

Theoretical hacking attacks exist but are extremely rare in practice. Criminals are far more likely to kick in a door or break a window than attempt a Bluetooth or Wi-Fi exploit. Use locks from reputable brands that issue firmware updates, enable two-factor authentication on your app, and pair with a monitored security system for layered protection.

Which smart lock works with HomeKit?

Schlage Encode Plus, Yale Assure Lock 2 (with HomeKit module), August Wi-Fi Smart Lock, Level Lock+, and Abode Lock (via the Abode hub) all support Apple HomeKit. The Schlage and Level also support Apple Home Key for tap-to-unlock.

Do smart locks work when the power goes out?

Yes. Smart locks run on batteries (AA or CR123A), not house power. Most last 6-12 months on a set of batteries. Many also have a physical key backup and emergency USB power port.

What’s the best smart lock for renters?

The August Wi-Fi Smart Lock — it installs over your existing deadbolt without any permanent modifications. When you move out, remove it and your original lock is intact. Takes under 10 minutes to install and remove.
