How We Compare Smart Locks

Every lock in this guide is evaluated on five criteria:

Criteria	What We Look For
Security	ANSI/BHMA grade, encryption standard, tamper protection
Installation	DIY-friendly? Tools required? Fits standard US doors?
Connectivity	Bluetooth, WiFi, gateway? Remote access capability?
Smart Home	Alexa, Google, Apple HomeKit compatibility
Value	Features per dollar, not just the lowest price

Smart Lock Categories — Which Type Fits Your Life?

Before comparing individual locks, understand the categories.

1. Deadbolt Replacement Locks

Best for: Homeowners who want a full upgrade.

These replace your existing deadbolt entirely. They look like traditional locks from the outside but pack smart features inside.

• Pros: Clean look, full feature set, most secure option
• Cons: Requires removing existing hardware, not always renter-friendly
• Example: Feocey X, August Smart Lock Pro

2. Retrofit Locks

Best for: Renters who can’t modify their door.

These attach to the inside of your door over the existing deadbolt. Your outside lock and key stay the same.

• Pros: No drilling, landlord-approved, easy to remove
• Cons: Bulkier on the inside, fewer features on some models
• Example: August Smart Lock, Wyze Lock

3. Keypad Deadbolts

Best for: Families and Airbnb hosts who want code-based entry.

A traditional deadbolt with a keypad. Enter a code to unlock. No smartphone required.

• Pros: Simple, no app dependency, great for guests
• Cons: No remote access (Bluetooth-only models), limited features
• Example: Schlage Encode, Kwikset Halo

4. Fingerprint Smart Locks

Best for: Personal use, fast one-touch access.

Biometric locks that read your fingerprint. No codes to remember, no phone to pull out.

• Pros: Fastest unlock method, can’t lose or forget your “key”
• Cons: Fingerprint sensors can struggle with wet/dirty fingers, usually more expensive
• Example: Ultraloq U-Bolt Pro, Eufy Smart Lock Touch

5. Smart Locks with Cameras

Best for: Front doors where you want to see who’s there.

A deadbolt + video doorbell in one device. Unlock and see visitors from one app.

• Pros: All-in-one security, see delivery people and guests
• Cons: Expensive, faster battery drain, bulkier design
• Example: Eufy Video Smart Lock, Lockly Vision

What to Avoid When Buying a Smart Lock

🚩 Red Flags:

1. “No-name” brands with no warranty. If you can’t find a real company behind the product, skip it. A lock is a security device, not a phone case.
2. Locks that require a hub but don’t include it. Check if the “WiFi” feature requires a separate $50-80 hub.
3. Proprietary apps with bad reviews. The hardware might be great, but if the app is buggy, you’ll hate using it daily. Check app store reviews before buying.
4. No auto-lock feature. You will forget to lock your door at some point. Auto-lock saves you.
5. Batteries that are hard to replace. Some locks require partial disassembly to change batteries. Look for external battery compartments.
