For most homes, the Schlage Encode Plus is the smart lock to buy first: it replaces the entire deadbolt with built-in Wi-Fi, a keypad and broad smart home compatibility, so there is no separate hub to manage. It is not the only good option, though, and the right smart lock depends on whether you want to keep your existing keys, use a fingerprint, or stick to one ecosystem.
We do not run lab tests here: we compare these locks from their specifications, documented features and aggregated user opinions on Amazon.

What to check before buying a smart lock
Retrofit vs. full deadbolt replacement. Some smart locks, like the August, attach over your existing deadbolt and turn it automatically, so you keep your original keys and exterior hardware. Others, like the Schlage Encode Plus, Yale Assure Lock 2 and Kwikset Halo Touch, replace the whole deadbolt with a new keypad or fingerprint reader built in.
Built-in Wi-Fi vs. a separate hub. A lock with built-in Wi-Fi connects straight to your router and works with a smartphone app from anywhere. Some smart locks need an extra bridge or hub for remote access, so check whether Wi-Fi is included before assuming full remote control is available out of the box.
Smart home compatibility. If you already use Alexa, Google Home or Apple Home, confirm the lock is certified for that specific ecosystem, since support varies by model and sometimes by which trim or bundle you buy.
Backup entry methods. A keypad code, a physical key backup, or a fingerprint sensor all matter if the battery dies or the network goes down. Most smart locks include at least a physical key override alongside their main unlock method.
A smart lock is only as secure as its installation. Confirm the lock is rated for your door thickness and backset before buying, and follow the included instructions closely, since a poorly mounted deadbolt undermines even the best electronics.
The best smart locks for home security
1. August Wi-Fi Smart Lock (4th Gen) with Keypad: best for keeping your existing keys
August Wi-Fi Smart Lock (4th Gen) with Keypad
The August fits over your current deadbolt and turns it automatically, so the outside of your door looks unchanged and your existing keys still work as a backup. According to user feedback, it is one of the fastest smart locks to install since there is no drilling or hardware replacement involved, and built-in Wi-Fi means remote locking and unlocking work without a separate hub.
Pros
- Installs over an existing deadbolt in minutes, no new hardware outside
- Keeps your original keys working as a backup
- Built-in Wi-Fi for remote lock and unlock
- Works with an included keypad for code-based entry
Cons
- Bulkier on the inside of the door than a full deadbolt replacement
- Depends on your existing deadbolt being in good working condition
2. Schlage Encode Plus Smart Wi-Fi Deadbolt: the best overall
Schlage Encode Plus Smart Wi-Fi Deadbolt
A full deadbolt replacement with a touchscreen keypad and built-in Wi-Fi, certified for Apple Home in addition to Alexa and other major platforms. Its combination of broad smart home support, a physical key backup and Schlage's established reputation in door hardware makes it the safest default pick for most homes.
3. Yale Assure Lock 2 with Wi-Fi and Keypad: best for modular options
Yale Assure Lock 2 with Wi-Fi and Keypad
The Assure Lock 2 uses a modular design that lets you swap the keypad module for a touchscreen or a fingerprint module later without replacing the whole lock. That flexibility makes it a good pick for anyone who wants to start with a keypad now and upgrade the unlock method down the line.
4. Kwikset Halo Touch Fingerprint Wi-Fi Smart Lock: best fingerprint unlock
Kwikset Halo Touch Fingerprint Wi-Fi Smart Lock
A deadbolt with a built-in fingerprint sensor as the primary unlock method, alongside built-in Wi-Fi and no separate hub required. It is the pick for households that want to skip codes and key fobs entirely and rely on a fingerprint for day-to-day entry, with a backup key for guests or in case of a dead battery.
How to choose
If you want the least disruptive upgrade, the August Wi-Fi Smart Lock keeps your existing keys and installs over your current deadbolt. For most homes starting from scratch, the Schlage Encode Plus is the safest all-around choice thanks to its wide smart home support. Anyone who wants room to upgrade later should look at the Yale Assure Lock 2's modular design, and households that prefer fingerprint entry over codes should go with the Kwikset Halo Touch.

Do smart locks work during a power outage?
Smart locks run on batteries, not household power, so a power outage does not affect them directly. However, a prolonged internet or Wi-Fi outage can disable remote app access, which is why most models keep a keypad code or physical key as backup.
How long do smart lock batteries last?
Most Wi-Fi smart locks last anywhere from six months to a year on a set of batteries, depending on usage and whether Wi-Fi is used constantly. Nearly all models warn you in the app well before the batteries actually die.
Can I install a smart lock myself?
Retrofit locks like the August are designed for a no-tools, few-minutes installation over an existing deadbolt. Full deadbolt replacements like the Schlage, Yale and Kwikset locks typically need a screwdriver and about 20 to 30 minutes, and are designed to fit standard door prep without extra drilling.
Are smart locks vulnerable to hacking?
Reputable brands build in encryption and undergo independent security testing (Schlage, Yale, August and Kwikset all publish certifications for their electronic locks). Using a strong Wi-Fi password and keeping the lock's firmware updated through its app are the most effective ways to reduce risk.
