Holiday season means a revolving door of guests, packages, dog sitters, and last-minute trips, and nothing makes it more stressful than hunting for a spare key. A smart lock fixes that. You can hand out temporary codes, unlock the door with your phone, and check from the airport that you actually locked up. If you've already upgraded your doorbell or smart plugs this fall, a smart lock is the natural next step.
We've rounded up what matters when shopping in 2026, plus five well-reviewed picks across different budgets and ecosystems.
What to Look for in a Smart Lock
- Retrofit vs. full replacement: Retrofit locks swap only the interior half and keep your existing exterior hardware and keys. They're great for renters. Full replacements give you a keypad or touchscreen on the outside.
- Smart home compatibility: Check for Matter, Apple Home, Google Home, or Alexa support, plus Thread or Wi-Fi connectivity, so it works with the gadgets you already own.
- Entry methods: Keypad codes, fingerprint, app, tap-to-unlock with your phone, and a physical key backup. More options means fewer lockouts.
- Guest access: Look for scheduled and temporary codes so the dog walker only gets in on weekdays.
- Battery life and backup: Most run on AA batteries for months. A low-battery alert and a 9V terminal or physical key for emergencies are must-haves.
5 Smart Lock Picks Worth Considering
1. August Wi-Fi Smart Lock (4th Gen): Best for Renters
This retrofit lock installs over your existing deadbolt, keeps your current keys working, and has built-in Wi-Fi, so no separate bridge is needed. It's a great fit if you can't change the exterior of your door. Shop August Wi-Fi Smart Lock on Amazon.
2. Yale Assure Lock 2: Best for Apple and Keypad Fans
A sleek keypad deadbolt with options for key-free touchscreen entry and Apple Home Key support on select models. Pick the connectivity module that suits your setup. Shop Yale Assure Lock 2 on Amazon.
3. Schlage Encode Plus: Best for Apple Home Key Tap-to-Unlock
Built-in Wi-Fi, a sturdy build, and support for tapping your iPhone or Apple Watch to unlock. It's a popular all-rounder for people who want a traditional keypad look with modern features. Shop Schlage Encode Plus on Amazon.
4. Level Bolt: Best Invisible Upgrade
Level hides the entire mechanism inside the door, so from the outside it looks like a normal deadbolt. It's ideal if you want smart features without changing your curb appeal. Shop Level Bolt on Amazon.
5. Aqara Smart Lock U200: Best for Smart Home Tinkerers
A feature-rich lock with multiple unlock methods and broad ecosystem support, often at a friendlier price than the big-name competition. Great for Matter and Thread enthusiasts. Shop Aqara Smart Lock U200 on Amazon.
How to Catch a Real Deal
Smart locks frequently go on sale in the run-up to Black Friday, but not every markdown is real. Before you buy:
- Check price history: A tracker like Keepa or CamelCamelCamel shows whether that "30% off" is truly lower than usual.
- Compare model years: Older generations are often discounted heavily and may offer nearly the same features.
- Confirm compatibility first: A cheap lock that doesn't work with your smart home platform isn't a bargain.
- Measure your door: Check backset and door thickness to make sure it'll fit before you click buy.
The Bottom Line
A smart lock is one of the most practical upgrades you can make before the holidays. Renters should look at a retrofit option like August, Apple users will love Schlage or Yale for tap-to-unlock, and tinkerers will get plenty from Aqara. Pick the one that fits your door and ecosystem, and you'll never scramble for a spare key again.
Prices and availability change often, so always check the current price on the retailer's site before purchasing.
