August 2nd Smart Lock – Keyless Home Entry with Smartphone, compatible with deadbolts , is the best smart lock available in 2020.

This is the smart lock we used to replace the deadbolt on the front door of our home. Thought the process was easy, we had some difficulty programming the wireless keypad.

But once we figured that out, we were able to sync things up with our smartphones and go hands free.

Frequently Asked Questions (FAQ)

Are smart locks any good?

Unless you have a pretty high-end smart lock at home, you’re likely missing out on remote monitoring, smart control, and smart access features. Deadbolts and doorknobs that are hooked up to the Internet of Things can help control your home with your smartphone from afar and give a more secure way to access your home.

What is the best Smart Lock?

The most important Smart Lock attribute is compatibility with your door, of course, although deadbolt locks are generally more compatible because of their design. Smart Locks that work with deadbolts are generally more secure than others. Some locks, like the Connect dongle, only work with certain doors so make sure you do your research regarding your door type.

The next thing you’ll need to research is how easy it is to install the lock. Some Smart Locks, like the August Smart Lock, are simple to install and need no tools. Others have specialty lock holes that might require drill bits or screws. If you want the Smart Lock to look nice and blend in with your door, you might want to consider one that uses your existing deadbolt lockhole. Some Smart Locks lose a little functionality because they use your existing holes.

What is the best door lock brand?

The best smart lock brand in my experience has been Yale. Their line of smart locks is highly reliable and very easy to control with the Android or Apple app. Since the units are wireless and battery-powered, the door lock is not affected by any power failure in your home.

This is an important point to consider when shopping for a smart lock. It makes no sense to buy a smart lock if it will not be able to function during a power failure. With this said, I strongly recommend having your existing lock professionally installed from Yale, Schlage, GE or another proven company. Not all locks are functional with smart technology and your lock may be one of these, so if you’re going to make the investment in a smart lock, make sure it’s going to work.

Which Smart Lock works best with Alexa?

The SmartThings Hub is the logical choice for home security users with an Alexa enabled device because you can monitor your entire household security through your voice. You can control your locks, lights, and cameras all through Alexa commands. However, it could be inconvenient to control your home automation hubs through Alexa when you are already using your smartphone or tablet to control your devices. I recommend combining the SmartThings Hub with the Wink Hub 2 if you want to be able to control both Alexa and your home router on the same device and don’t need Alexa.

Conclusion

Ultimately, whether you choose a Z-Wave, Zigbee or Bluetooth smart lock, you should consider what your locks are going to be used for. We would recommend Z-Wave locks to users who often leave their home for extended periods of time and/or want more control over who is allowed access to their home. We would recommend the Smartcode 914 for this purpose.
