How We Chose The Best Smart Locks

With more and more smart devices hitting the shelves every day, finding the best options can be challenging. In order to find the best smart locks amongst the thousands of available options, we decided to focus on a few simple criteria: security, accessibility, and ease of use.

High Security

As you would expect, the most important feature of any lock is security. You have to look for solid construction and quality materials. When it comes to smart locks, you also have to consider digital security. All of the locks on our list come with 128-bit data encryption, a level of encryption often used in banks, so you can rely on these smart locks to keep your home and family safe.

Accessibility Options

One of the best things about smart locks is that they provide alternative entry options. Instead of having to fumble with your keys when your hands are full or find a way to carry your keys and phone when you’re out for a run, you can have options that better fit your lifestyle such as keyless or automatic unlocking. That’s why we chose smart locks with multiple entry options so that there would be something here to fit every lifestyle.

Ease of Use

Installing new smart devices can be complicated, but not with these smart locks! All of the locks on our list offer easy installation and set up. All of them can be installed without the help of a professional and most take less than 10 minutes to set up.

Not only are all of these locks easy to install, but they are easy to use as well. With multiple entry options for each style of lock, you can ensure that no one in your family is ever left stranded outside.

What You Need To Know About Smart Locks

As far as smart products go, smart locks are fairly straightforward, but just in case this is your first foray into the field of smart locks, here is a little information that you may find useful.

Are Smart Locks Safe?

One of the most common questions that you’ll hear about smart locks is: Are they truly safe? When electronic locks first came into being, there were some serious issues with hackers being able to duplicate the access codes and open locks with ease. Thankfully, the technology involved has improved significantly since then. Many smart locks are not only highly-encrypted, but they also have built-in alarms that will alert you of any suspicious occurrences or attempted tampering. That is not to say that all smart locks are 100 percent secure, but they can in fact be more secure than traditional locks.

With traditional key-entry locks, there is always the chance of keys being lost or stolen. If a key is lost, you have to deal with the frustration and expense of rekeying the doors or replacing the hardware altogether. If you often have guests when you’re away from home, you also have to deal with the hassle of giving out extra keys or hiding a spare, which is a serious security risk. And, last but not least, there is always the possibility of someone picking the lock.

Smart locks remove nearly all of these risks. You never have to worry about hiding a spare key or giving keys out to friends or lodgers. You can simply grant them access remotely through your smartphone or give them a keycode of their own. The codes can be deleted and replaced as often as you like without any trouble or extra expense. Plus, most smart locks also keep a log of who is coming and going, so you always know when and why your door was unlocked.

If you’re looking to update more than just your lock, we also reviewed the best smart doorbell options.

What Happens If The Power Goes Out?

Everyone has heard stories about people getting locked out of their home or business because the electronic lock wasn’t working. Thankfully, with most modern smart locks, this is no longer an issue. All of the locks on our list are battery-powered, meaning the lock itself would not be affected by a power outage. If your lock has an automatic feature or a keypad, the lock will work as normal. Many of the best smart locks also offer a key-entry feature as a backup, just in case something does go wrong.

It is important to note that these locks rely on WiFi for remote use. So if your WiFi is down due to a power outage, you would have to rely on the Bluetooth option to open the door, but you would still be able to get in.

Can I Install It Myself?

As we mentioned in the previous section, these locks are quite user-friendly and that includes installation. None of the models on our list require hardwiring, so they are as easy to install as a regular deadbolt. Some even attach to your existing deadbolt, making them even easier to install. You’ll need to be a bit tech-savvy to set up the app, but if you’re accustomed to using a smartphone, you shouldn’t have any trouble completing the setup within 10 to 15 minutes.

How to Choose The Best Smart Lock For Your Home

Now that you know all about smart locks and how easy they are to use, let’s talk about how you can choose the best smart lock for your home. Thankfully, there are only two main factors to consider: security and entry options.


As you can probably guess, the primary concern is security, both physical and digital. Look for a lock made from quality materials, just as you would with a regular deadbolt. When it comes to digital security, be sure to look for a smart lock that offers solid encryption, preferably AES 128-bit encryption.

Entry Options

The next consideration will be entry options. What kind of features will you need to best fit your style and security needs? If the lock is primarily for your home then hands-free automatic entry may be the most important feature. If you love your smart home hub and want to be able to lock and unlock with voice commands, then connectivity will be a high-priority. Looking for a new lock for your rental or Airbnb? You will likely want to choose a unit with a keypad so that you assign new keycodes for each guest. Keep in mind that most smart locks come with multiple entry-options, so there’s an option to fit every situation. Simply consider which features stand out the most to you and choose accordingly.

Bottom Line

Smart locks are a great example of how technology can be used to improve our everyday lives. With a quality smart lock, you no longer have to worry about losing keys or having to make spares. You’ll no longer have to wonder about whether you locked the front door or not, you can simply pull out your phone and check. You may not even realize how much time you spend worrying about these things until you don’t have to think about them anymore.

You can’t go wrong with any of our top picks, but we recommend the ULTRALOQ U-Bolt Pro Smart Lock.
