5 Best Smart Locks on Amazon in 2026 — Secure Your Front Door

For years, I refused to install a smart lock on my front door. I trusted a heavy piece of brass over a Bluetooth connection any day. But after the third time my kids lost their house keys (and after paying a locksmith $150 to get us back inside), I finally caved.

I quickly learned that the smart lock market is a minefield. Some drain batteries in three weeks. Others require a separate $50 Wi-Fi hub just to connect to the internet. And some have apps so poorly designed you'd think they were built in 2012.

I've spent the last six months testing the top-rated models on my own front door. These are the 5 best smart locks on Amazon in 2026 that offer real security, reliable connectivity, and actually make your life easier.

1. Schlage Encode Plus: The Best Overall (and Best for Apple Users)

If you use an iPhone, stop reading this list and just buy the Schlage Encode Plus. It is the absolute gold standard for smart locks right now.

What makes it so special is its integration with Apple Home Key. You don't even have to open an app or use a keypad—you just tap your iPhone or Apple Watch against the lock, and the deadbolt slides open instantly. It works even if your phone battery is dead (using power reserve mode).

It connects directly to your Wi-Fi (no hub required) and has a built-in alarm that blares if someone tries to tamper with it. It is incredibly heavy-duty and carries a Grade 1 security rating, the highest residential rating possible.

Pros:

Apple Home Key support (tap to unlock)
Grade 1 security rating
Built-in Wi-Fi (no extra hub needed)

Cons:

Very expensive
Bulky interior housing

2. Yale Assure Lock 2: The Best for Google & Alexa Homes

If you are heavily invested in the Google Assistant or Amazon Alexa ecosystems, the Yale Assure Lock 2 is the sleekest, most reliable option available.

Yale redesigned this lock to be 30% smaller than the previous generation, so it doesn't look like a massive computer glued to your door. It features a beautiful matte keypad that wakes up when you touch it.

The auto-unlock feature is the best I've tested. It uses geofencing to sense when you pull into your driveway, and by the time you walk up to the door with an armful of groceries, the door is already unlocked.

Note: Make sure you buy the Wi-Fi version, not just the Bluetooth version, unless you already have a compatible smart home hub.

Pros:

Sleek, modern design (much smaller than competitors)
Flawless auto-unlock feature
Great integration with Google and Alexa

Cons:

Battery life is only about 3-4 months with Wi-Fi on
The setup process in the app can be finicky

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

If you live in an apartment, rent a house, or just really love the exterior hardware on your front door, you need a retrofit lock. The August Wi-Fi Smart Lock only replaces the thumb turn on the inside of your door. The outside remains completely unchanged, and your original keys will still work.

Because it doesn't have an exterior keypad, you control it entirely via the August app, auto-unlock, or a smart assistant.

It is incredibly easy to install. I had it up and running in less than 10 minutes using only a Phillips-head screwdriver. The 4th generation model is 45% smaller than the original and finally has Wi-Fi built-in, so you don't need to plug an ugly bridge into your wall outlet.

Pros:

10-minute installation
Keep your existing exterior hardware and keys
Excellent, reliable app

Cons:

Uses expensive CR123 batteries (not standard AA)
No exterior keypad for guests (must use the app)

4. Eufy Security S330 Video Smart Lock: Best All-in-One

If you don't already have a video doorbell (like a Ring or Nest), the Eufy Security S330 solves two problems at once. It is a premium smart lock and a 2K video doorbell combined into one sleek device.

The best feature of this lock is the fingerprint scanner. It reads your print and unlocks the door in under 0.3 seconds. It's faster than using a key, faster than a keypad, and faster than opening an app.

The camera is incredibly sharp, and unlike Ring, Eufy does not charge a monthly subscription fee to store your video clips. Everything is stored locally on the included chime box.

Pros:

Incredible fingerprint scanner
2K camera built-in
No monthly subscription fees for video storage

Cons:

The battery is proprietary and must be removed to charge
Very large exterior footprint

5. Kwikset Halo Wi-Fi: Best Budget Pick

Smart locks are expensive, but you don't have to spend $300 to get a good one. The Kwikset Halo frequently goes on sale for around $130, making it one of the best values on Amazon.

It connects directly to your Wi-Fi router, allowing you to create up to 250 unique user codes. This is perfect if you run an Airbnb, have a dog walker, or need to let a contractor in while you are at work. You can set codes to only work on specific days and times.

It also features Kwikset's SmartKey security, which allows you to re-key the lock yourself in seconds to match your other house keys.

Pros:

Great price for a Wi-Fi-enabled lock
Create up to 250 scheduled user codes
Easily re-key to match existing Kwikset keys

Cons:

The app is a bit basic compared to August or Yale
Motor is noticeably louder than competitors

FAQ: Buying a Smart Lock on Amazon

Do smart locks work if the power or Wi-Fi goes out?

Yes. Smart locks run on batteries (usually AA), so a power outage won't affect them. If your Wi-Fi goes down, you won't be able to control the lock remotely from your phone, but the physical keypad, fingerprint scanner, or traditional key will still work perfectly.

How long do the batteries last?

Most smart locks with built-in Wi-Fi will burn through a set of AA batteries in 3 to 6 months. Locks that use a separate Wi-Fi bridge (or only use Bluetooth) can last up to a year. The app will warn you weeks in advance when the battery is getting low.

What happens if the lock battery dies completely?

If you ignore the low-battery warnings for a month and it dies completely, most locks have a physical keyhole as a backup. If you buy a lock without a keyhole (like some Yale Assure models), they have two metal prongs on the bottom. You can press a standard 9V battery against those prongs to temporarily power the lock and enter your code.
