The Best Smart Locks for 2021 | Can be Controlled by a Smartphone

Coming home after a long day and having to fiddle around for your keys because thanks to winter it’s already dark isn’t fun. Luckily, modern tech has come up with a solution: smart door locks. Read ahead for what they do, how to choose the best setup, and our top picks for 2021!


Home security is an issue on everyone’s mind, and the market for smart home security keeps on growing. Keeping your family safe is the most important consideration, but convenience and monitoring are also great reasons to choose a smart door lock over a standard deadbolt. There are thousands of products on the market and lots of different features, so how do you pick the best one? Let’s start with the basics first.

The Basics of a Smart Door Lock

Smart WiFi Door Locks utilize technology to let you lock/unlock your door via smartphone, key fob, fingerprint, or voice control. These locks provide keyless entry, and many devices even give you remote access to allow friends and family in. In addition, many smart locks let you know when your door is accessed. Smart Door Locks can either replace or integrate with your existing deadbolt lock. Being able to track activity lends peace of mind, especially if you have children. Another cool feature is the ability to use temporary codes. Have a maintenance issue but won’t be home during business hours? Simply give the worker a temporary code and your issue is solved. This feature is also great for AirBnBs and rental properties.

Installation and Use

Most smart door locks are easy to install and do not require an electrician or locksmith. Many locks these days pride themselves on being user-friendly. Always make sure to follow the manufacturer’s directions when installing. Simple tools such as a screwdriver are usually all you need. Some models only work with certain types of door handles (such as lever vs. knob) or won’t work with a door over a certain thickness. Before purchasing, it’s a good idea to have basic measurements handy. If your door will be directly exposed to elements like rain or snow, take special care to choose a weatherproof model. Some smart door locks don’t have an outdoor component, so if this is a major concern, that may be the best choice.

Costs and Compatibility

Like with most gadgets, there’s a spectrum of prices available. An electronic keypad smart door lock will set you back less than $50, while a smart WiFi door lock with lots of features will cost a bit under $300. As a general rule of thumb, the more features a smart door lock has, the more expensive it will be. With that said, options for any budget are available. Knowing you are keeping your family and possessions safe is worth the investment.

A smart door lock can be a standalone purchase, but it is very likely only one component of your Smart Home and security measures. Compatibility varies from brand to brand. Popular systems like Alexa, Siri, Google Assistant, and Ring are often able to be connected. If you want your smart lock to work with a particular system, check the manufacturer’s specifications to verify it will be a good fit. Most smart door apps are created with both iOS and Android versions, so as long as you have a smartphone, you should be good to go. If you have another operating system or your phone is particularly old, you may want to look into exact specifications. You can also use a hub, which will cut down on the number of apps you need as well.

Emergency Considerations

Depleted lock battery, an electric outage or WiFi interruptions seem like the high-tech version of leaving your keys at the office, but there are ways around these issues. Most locks have workarounds that will still allow for functionality, such as Bluetooth or keypad functionality. Battery-operated models usually come with built-in low battery warning. As with any equipment, routine inspection and paying attention to alerts will go a long way in preventing issues. When choosing your device, make sure you are comfortable with the emergency options offered.

Commonly Asked Questions

 

Question: Do all smart locks require a hub?

A hub is the brain of your smart home and controls all of the devices. This hub will allow you to control your devices remotely, which is especially handy when you’re not there in person. Many people prefer hubs because they can use one app instead of different apps for different devices. However, many smart locks utilize home WiFi or Bluetooth, giving you more options. If using home WiFi, you may need a WiFi extender. When deliberating on your purchase, see what type of hub a smart door lock works with, and see what the lock itself comes with.

 

Question: What smart locks work with Alexa?

Thanks to voice control’s popularity, the majority of smart door locks these days are equipped to be compatible with Alexa or Google Assistant. This does vary from lock to lock, so it’s something to consider before purchasing.

 

Q: Can Alexa lock my door?

A: Most smart door locks are designed to be Alexa-compatible. When choosing your smart lock, check in the product description to make sure. To prevent a random person from unlocking your door with a voice command, Alexa will require a PIN that will verify it is you. Eventually, technology will progress so that voice recognition is widely used, but for now, there are other safeguards in place.

 

Q: Can smart locks be hacked?

A: Technically, yes. Any device with outside connectivity can be hacked. Internal security has been ramped up in the past few years to try to prevent this. Only give outdoor codes to those you trust, and keep your app passwords complex and difficult to guess. Many smart locks let you open the door hands-free by having your phone in your pocket. Make sure that your phone is secured with a password and you have some method of turning off usability in the case your phone is stolen. Additionally, purchase your smart door lock from a reputable company. The products we’ve included in our list come from renowned tech and security brands known for quality devices. Changing your passwords and door codes frequently is a good move as well.

 

Q: Will a smart door lock make my door more secure?

A: Homes without any security system are 300% more likely to be broken into according to recent statistics. Smart door locks can serve as a deterrent and many can function within a system of other home security devices. With a smart lock, you are much less likely to lose your key or have a hidden key found by a burglar. Be mindful to follow all manufacturer advisories for use and upkeep. An improperly used smart lock can compromise your safety. Overall, using keyless entry and being able to monitor your door’s usage remotely has a positive impact on home security.
