Cons
- Wi-Fi module is an extra cost
- Keypad can be hard to read in direct sunlight
The Yale Assure Lock 2 is a full replacement deadbolt that offers a clean touchscreen keypad and a modular design. You can buy the lock without Wi-Fi and add the module later if needed, making it a flexible option for budget-conscious buyers.
Owner reviews praise the long battery life and the smooth operation of the touchscreen. The lock is compatible with Alexa, Google Assistant, and Siri, and it integrates with the August app for remote access. The main complaint is the extra cost for the Wi-Fi module, which is required for remote control.

Best for Apple Home KeyPros
- ANSI Grade 1 security rating (highest)
- Built-in Wi-Fi and Thread for fast response
- Supports Apple Home Key for NFC unlock

The Schlage Encode Plus is the premium choice for Apple users, offering built-in Wi-Fi and Thread connectivity for fast, reliable performance. It features a built-in keypad and supports Apple Home Key, allowing you to unlock your door with a tap of your iPhone or Apple Watch.
Owner reviews consistently praise the build quality and the ANSI Grade 1 security rating, which is the highest residential standard. The lock is also compatible with Alexa and Google Assistant. The main downside is the premium price, but for those wanting top security and Apple integration, it is worth the investment.
Ring Smart Lock Pro
Best for Ring EcosystemPros
- Integrates seamlessly with Ring Alarm and cameras
- Auto-lock and auto-unlock with geofencing
- Works with existing deadbolt and key
Cons
- Requires Ring Bridge or Alarm base station
- No built-in keypad (sold separately)

Owner reviews note that the geofencing auto-unlock works well, and the lock is easy to install over an existing deadbolt. The main drawbacks are the need for a separate bridge and the lack of a built-in keypad, which requires an additional purchase for keyless entry.

Owner reviews appreciate the convenience of fingerprint access, especially for family members without phones. However, some users report that the sensor struggles with wet or dirty fingers. The app is functional but not as refined as the August or Yale apps.
What to check before buying a smart lock
Before purchasing a smart lock for your front door, verify your door's compatibility. Measure the backset (distance from edge of door to center of deadbolt hole) and check the thickness of your door. Most smart locks fit standard doors, but some require specific dimensions.
Consider your existing smart home ecosystem. If you use Amazon Alexa, Google Assistant, or Apple HomeKit, ensure the lock supports your preferred platform. Also, check if the lock requires a separate hub or bridge for remote access, as this adds to the total cost.
Battery life is another key factor. Most smart locks use AA batteries and last 3-12 months. Look for locks with low-battery alerts and physical key override options for emergencies.
Mistakes to avoid
One common mistake is buying a lock that does not fit your existing deadbolt. Always check if the lock is a retrofit model (fits over your existing deadbolt) or a full replacement. Retrofit models like the August are easier to install but may not fit all deadbolts.
Another mistake is ignoring security ratings. Look for ANSI Grade 1 or Grade 2 certification for residential security. Avoid locks with no visible security rating, as they may not be as durable against forced entry.
Finally, do not overlook the importance of a backup key. Even the best smart lock can run out of battery or have connectivity issues. Choose a model that includes a physical key override or a 9V battery backup terminal on the exterior.
FAQs
Do smart locks work with any door?
Most smart locks fit standard US doors with a 2-3/8 inch or 2-3/4 inch backset and a thickness of 1-3/8 to 1-3/4 inches. Always check the manufacturer's specifications before buying.
Can I still use my regular key with a smart lock?
Many smart locks, like the August Wi-Fi Smart Lock, allow you to keep your existing key and deadbolt. Full replacement locks often include a physical key override.
Do smart locks require a hub?
Some smart locks have built-in Wi-Fi and do not need a hub. Others, like the Ring Smart Lock Pro, require a separate bridge or alarm base station for remote access.
How long do smart lock batteries last?
Battery life typically ranges from 3 to 12 months depending on usage, connectivity type, and temperature. Most locks provide low-battery alerts in the app.
Are smart locks secure?
Yes, smart locks with ANSI Grade 1 or Grade 2 certification offer strong physical security. Digital security depends on encryption and regular firmware updates from the manufacturer.
Can I install a smart lock myself?
Retrofit models like the August are easy to install with just a screwdriver. Full replacement locks may require more effort, but most are DIY-friendly with clear instructions.
Do smart locks work with Alexa or Google?
Most modern smart locks support Alexa and Google Assistant for voice control. Check the product specifications for specific compatibility.
What happens if the battery dies?
Most smart locks have a physical key override or an external 9V battery terminal. Always keep the backup key accessible outside your home.
Can I use a smart lock with a rental property?
Yes, retrofit models are ideal for rentals because they do not require changing the lockset. Always check with your landlord before installing.
What is the difference between Bluetooth and Wi-Fi smart locks?
Bluetooth locks only work when you are nearby, while Wi-Fi locks allow remote access from anywhere. Wi-Fi locks consume more battery but offer greater convenience.
