August Wi-Fi Smart Lock (4th Gen)
Best OverallPros
- Easy DIY install in 10 minutes
- Works with Alexa, Google, and HomeKit
- Auto-unlock and auto-lock features
Cons
- Requires existing deadbolt
- Bulky exterior plate on some doors
The August Wi-Fi Smart Lock (4th Gen) stands out because it retrofits over your existing deadbolt. You keep your original key and lock hardware on the outside, while the smart module replaces the interior thumb turn. This makes it one of the easiest smart locks to install without changing your keys.
Owner reviews highlight the reliable auto-unlock feature, which uses your phone's location to unlock the door as you approach. The built-in Wi-Fi eliminates the need for a separate hub, and the battery life is rated at 3-6 months depending on usage. Some users note the lock can be slow to respond over Wi-Fi, but overall it offers the best balance of features and simplicity.
Yale Assure Lock 2 Touch
Best Budget / FingerprintPros
- Fast and accurate fingerprint reader
- Affordable price point
- Works with Yale Access app
Cons
- Wi-Fi module sold separately
- No HomeKit support without module
The Yale Assure Lock 2 Touch offers a built-in fingerprint reader at a price that undercuts most competitors. The touchscreen keypad and fingerprint sensor provide quick entry without needing your phone. It is a good choice for families who want multiple access methods.
Owner reviews praise the battery life, which often exceeds the rated 6 months. The lock is easy to install on a standard door. The main drawback is that Wi-Fi connectivity requires a separate Yale Wi-Fi module, adding to the cost if you want remote access. Without it, you are limited to Bluetooth range.
Ring Alarm Smart Lock (2nd Gen)
Best for Ring EcosystemPros
- Seamless Ring Alarm integration
- Auto-lock and disarm features
- Works with existing deadbolt
Cons
- Requires Ring Bridge or Alarm base
- No built-in keypad
The Ring Alarm Smart Lock (2nd Gen) is designed to work exclusively with the Ring Alarm security system. It can automatically lock when you arm the system and unlock when you disarm it. This integration makes it a natural fit for existing Ring users.
Owner reviews note the lock is reliable and the battery life is solid. The main limitation is that it requires a Ring Bridge or Alarm base station to function, so it is not a standalone lock. It also lacks a built-in keypad, meaning you need your phone or the Ring app to unlock it.
Schlage Encode Plus
Best for Apple Home KeyPros
- Built-in Wi-Fi, no hub needed
- Apple Home Key support
- Solid build quality
Cons
- Higher price than competitors
- Large exterior footprint
The Schlage Encode Plus is a premium lock that supports Apple Home Key, allowing you to unlock your door with a tap of your iPhone or Apple Watch. It also has built-in Wi-Fi and Thread, so it works with HomeKit without a separate hub. The keypad and physical key provide backup options.
Owner reviews highlight the robust construction and reliable performance. The lock is easy to install and the Schlage app is straightforward. The main downside is the price, which is higher than many alternatives. The lock is also physically larger, which may not suit all doors.
Level Lock+
Best Minimalist DesignPros
- Invisible design, looks like a standard lock
- Works with HomeKit
- Quiet operation
Cons
- No built-in keypad
- Slow response times reported
The Level Lock+ is designed to be completely hidden inside your door. From the outside, it looks like a standard deadbolt. The smart components are concealed, making it the most discreet smart lock available. It supports Apple HomeKit and works with the Level app.
Owner reviews appreciate the minimalist aesthetic and quiet motor. However, the lack of a keypad means you must use your phone or a physical key to unlock it. Some users report slower response times compared to other locks, and the setup can be finicky. It is best for those who prioritize appearance over features.
What to Check Before Buying a Smart Lock
Before you buy, check your door's thickness and backset. Most smart locks fit standard 1 3/8 to 1 3/4 inch doors with a 2 3/8 or 2 3/4 inch backset. Verify that your door is pre-drilled for a deadbolt. If you have a mortise lock or a non-standard door, your options are limited.
Consider your smart home ecosystem. If you use Apple HomeKit, look for locks with native HomeKit or Thread support. For Amazon Alexa or Google Assistant users, most Wi-Fi locks work well. Z-Wave locks require a separate hub but offer better reliability.
Mistakes to Avoid
Do not buy a lock that requires a subscription for basic features. Some locks hide remote access behind a monthly fee. Also, avoid locks with poor battery life or those that do not provide a low-battery warning. A lock that dies without warning can leave you locked out.
Do not ignore the physical key backup. Even the best smart locks can fail due to dead batteries or software issues. A physical key ensures you can always get in. Finally, check that the lock is ANSI Grade 1 or 2 certified for security.
